solve the system of linear equation by graphing
y=x-7
y=-2x+5​

According to the question  ⅆyⅆx at the point (2,8) is -12/103.

We start by implicitly differentiating the given equation with respect to x:

3x^2 + 13y(dy/dx) = dy/dx

Now we substitute the values x = 2 and y = 8:

3(2)^2 + 13(8)(dy/dx) = dy/dx

12 + 104(dy/dx) = dy/dx

Simplifying, we get:

104(dy/dx) - dy/dx = -12

(104-1)(dy/dx) = -12

103(dy/dx) = -12

dy/dx = -12/103

If √ x √ y = 12 and y ( 9 ) = 81 ,then by implicit differentiation y ' = -6.75.

Starting with the equation √x√y = 12, we can differentiate both sides with respect to x using the chain rule:

d/dx [√x√y] = d/dx [12]

Using the chain rule on the left-hand side, we get:

(1/2)(y/x^(3/2)) dx/dx + (1/2)(x/y^(1/2)) dy/dx = 0

Simplifying this expression gives:

y/x^(3/2) dx/dx + x/y^(3/2) dy/dx = 0

Since we are asked to find y'(9), we can substitute x = 9 and y = 81 into this equation:

y/9^(3/2) dx/dx + 9/y^(3/2) dy/dx = 0

Simplifying this expression further by substituting √y = 12/√x, which follows from the original equation, gives:

y/27 dx/dx + 9/(4x) dy/dx = 0

We are given that y(9) = 81, which means x√y = √(xy) = 36, since √x√y = 12. Therefore, xy = 36^2 = 1296.

Differentiating this equation with respect to x using the product rule gives:

x dy/dx + y dx/dx = 0

Solving for dy/dx, we get:

dy/dx = -y/x

Substituting this into the expression for dy/dx in terms of x and y above, we get:

y/27 dx/dx + 9/(4x) (-y/x) = 0

Simplifying this equation gives:

y' = (-3/4) y/x

Substituting x = 9 and y = 81 gives:

y'(9) = (-3/4) (81/9) = -6.75

Therefore, y'(9) = -6.75.

The material is unable to store energy and instead dissipates it, exhibiting a purely viscous response.

Viscoelastic materials exhibit both viscous and elastic behavior under deformation. The storage modulus (G') and loss modulus (G'') are two measures of the viscoelastic response of a material. The storage modulus represents the elastic response of the material and is a measure of its ability to store energy, while the loss modulus represents the viscous response and is a measure of its ability to dissipate energy.

In the context of a dynamic mechanical analysis (DMA) experiment, the storage and loss moduli are defined as:

G' = σ' / γ

G'' = σ'' / γ

where σ' and σ'' are the in-phase and out-of-phase components of the stress, respectively, and γ is the strain amplitude. The phase lag angle δ is defined as the difference between the phase angles of the stress and strain, given by:

tan δ = G'' / G'

For purely viscous materials, the storage modulus is zero and the loss modulus is nonzero. In this case, the phase angle is π/2, indicating that the stress is 90 degrees out of phase with the strain. This means that the material is unable to store energy and instead dissipates it, exhibiting a purely viscous response.

To find the change-of-coordinates matrix from basis b to the standard basis c, we need to express each vector in b in terms of the vectors in c, and then use those coefficients to form the matrix.

Let's first express b in terms of c. We want to find constants a, b, and c such that:

1 − 3t t^2 = a(1) + b(t) + c(t^2)

2 − 5t 3t^2 = a(0) + b(1) + c(t^2)

2 − 3t 6t^2 = a(0) + b(0) + c(1)

From the third equation, we can see that c = 6t^2. Substituting into the first equation and solving for a and b, we get:

1 − 3t t^2 = a(1) + b(t) + 6t^2(t^2)

1 − 3t t^2 = a + (b + 6)t^2

a = 1

b = −3

Substituting c = 6t^2, a = 1, and b = −3 into the second equation, we get:

2 − 5t 3t^2 = −3t + 6t^2(t^2)

2 − 5t 3t^2 = 6t^4 − 3t

change-of-coordinates matrix from b to c is:

[1 −3 0]

[0 6 −3]

[0 0 6]

To find the b-coordinate vector for 2 − 5t 4t^2, we need to express this vector in terms of the basis vectors in b:

2 − 5t 4t^2 = a(1 − 3t t^2) + b(2 − 5t 3t^2) + c(2 − 3t 6t^2)

Substituting the values we found for a, b, and c, we get:

2 − 5t 4t^2 = 1(1 − 3t t^2) − 2(2 − 5t 3t^2) + 4(2 − 3t 6t^2)

Simplifying, we get:

The solution to the integral equation using Laplace transform is:

y(t) = (1/16)e^2t - (1/16)e^-2t + (1/4)

To solve the integral equation y(t) 16∫t0(t−v)y(v)dv=12t using Laplace transforms, we need to apply the Laplace transform to both sides and solve for y(s).

Applying the Laplace transform to both sides of the given integral equation, we get:

Ly(t) * 16[1/s^2] * [1 - e^-st] * Ly(t) = 1/(s^2) * 1/(s-1/2)

Simplifying the above equation and solving for Ly(t), we get:

Ly(t) = 1/(s^3 - 8s)

Now, we need to find the inverse Laplace transform of Ly(t) to get y(t). To do this, we need to decompose Ly(t) into partial fractions as follows:

Ly(t) = A/(s-2) + B/(s+2) + C/s

Solving for the constants A, B, and C, we get:

A = 1/16, B = -1/16, and C = 1/4

Therefore, the inverse Laplace transform of Ly(t) is given by:

y(t) = (1/16)e^2t - (1/16)e^-2t + (1/4)

Hence, the solution to the integral equation is:

y(t) = (1/16)e^2t - (1/16)e^-2t + (1/4)

There are 6 units between the highest and lowest points in the motion of the weight.

To find the number of units between the highest and lowest points in the motion of the weight described by the equation f(x) = 3 cos(2x), we need to analyze the amplitude of the function.

The amplitude of a cosine function is represented by the coefficient of the cos(2x) term. In this case, the amplitude is 3. Since the cosine function oscillates between -1 and 1, the highest point of the motion occurs at 3 * 1 = 3, and the lowest point occurs at 3 * (-1) = -3.

To find the number of units between the highest and lowest points, subtract the lowest point from the highest point: 3 - (-3) = 3 + 3 = 6 units.

Write the equation 4x + 1 = 2y + 6 in slope-intercept form

Answer: Let x be the cost of one slice of pizza and y be the cost of one soda.

From the problem, we know that:

6x + 4y = 37 ...(1)

4x + 6y = 33 ...(2)

To solve for x and y, we can use the method of elimination. Multiplying equation (1) by 3 and equation (2) by 2, we get:

18x + 12y = 111 ...(3)

8x + 12y = 66 ...(4)

Subtracting equation (4) from equation (3), we get:

10x = 45

Dividing both sides by 10, we get:

x = 4.50

Substituting this value of x into equation (1), we get:

6(4.50) + 4y = 37

Simplifying, we get:

27 + 4y = 37

Subtracting 27 from both sides, we get:

4y = 10

Dividing both sides by 4, we get:

y = 2.50

Therefore, one slice of pizza costs $4.50 and one soda costs $2.50.

To find the duration of the award show, we need to subtract the start time from the end time. We can do this by breaking down the times into hours and minutes, and then subtracting the corresponding hours and minutes.

The start time is 23:30 (11:30 PM) and the end time is 2:55 (2:55 AM). However, we cannot subtract 23 from 2, as that would give us a negative value. Instead, we add 12 to the end time to convert it to a 24-hour format.

2:55 + 12:00 = 14:55

Now we can subtract the start time from the end time:

14:55 - 23:30 = 14:55 - 23:30 = 1:35

Therefore, the duration of the award show was 1 hour and 35 minutes. It's important to note that this assumes that the start and end times are given in the same time zone. If the times are given in different time zones, we would need to take into account any time differences between the two.

Let's find the values of m and n when p² + p + 2 is a factor of

f(p) = p⁴ - mp³ - 5p² + 8p - n.

To know that

p² + p + 2 is a factor of f(p),

we will divide

p⁴ - mp³ - 5p² + 8p - n by p² + p + 2 by long division.

We'll have:           __________p² │p⁴ - mp³ - 5p² + 8p - n-p⁴ - p³ - 2p²      -mp³ + mp² - 3p² + 8p      _________________         mp³ - mp² - 2p² + 8p - n         -mp³ - mp² - 2mp      ___________________                2mp² + 8p - n                  -2mp² - 2mp - 4p              _______________                        10p + n

The remainder is 10p + n.

Since p² + p + 2 is a factor of f(p), then

p² + p + 2

will divide the remainder,

10p + n, with zero remainder.

That is, if we substitute p = -2 in 10p + n, we'll get

10(-2) + n = -20 + n.

Since -2 is a root of p² + p + 2,

then -20 + n = 0, which implies n = 20.

Substitute p = -1 in the remainder,

10p + n, we have 10(-1) + n = -10 + n.

Since -1 is also a root of p² + p + 2,

then -10 + n = 0,

which implies n = 10.

So, we have two values for n, 10 and 20.

To find m, we substitute the value of n in the quotient we got earlier:

2mp² + 8p - n = 0,

we substitute

n = 10 to get:

2mp² + 8p - 10 = 0

The general form of a quadratic equation is

ax² + bx + c = 0.

Comparing it with 2mp² + 8p - 10 = 0, we get:

a = 2m, b = 8, and c = -10

We know that the equation p² + p + 2 = 0 has two roots.

Let's solve it by the quadratic formula:

p = [-(1) ± √(1² - 4(2)(2))] / (2(2))p = [-1 ± √(1 - 16)] / 4p = [-1 ± √(-15)] / 4

Since the roots of p² + p + 2 = 0 are complex, then m is also complex, so we have:

m = α + iβor m = α - iβ

where α and β are real numbers.

We'll substitute

p = -1 - i in the quadratic equation

2mp² + 8p - 10 = 0 to get:

2m(-1 - i)² + 8(-1 - i) - 10 = 0

Expanding (-1 - i)², we get:

2m(1 - 2i - i²) + (-8 - 8i) - 10 = 02m(-1 - 2i) + (-18 - 8i) = 02m(-1) + (-18) = 0

Therefore, m = 9.

Substituting p = -1 + i in the quadratic equation

2mp² + 8p - 10 = 0, we get:

2m(-1 + i)² + 8(-1 + i) - 10 = 0

Expanding (-1 + i)², we get:

2m(1 + 2i - i²) + (-8 + 8i) - 10 = 02m(-1) + (2 - 8) = 0

Therefore, m = 3.

To prove that idt ◦f = f, we need to show that they have the same mappings. This can be done by applying both functions to each element of set s and comparing the results. By definition of the identity function, we know that idt(x) = x for all x in set t. Therefore, idt ◦f(x) = f(x) for all x in set s.

Step 1: Define the identity function id_T: T → T. For any element x in T, id_T(x) = x.

For any x in S, (id_T ◦ f)(x) = id_T(f(x)) by definition of composition. Since id_T is the identity function on T and f(x) is an element of T, id_T(f(x)) = f(x). Thus, (id_T ◦ f)(x) = f(x) for all x in S, proving that id_T ◦ f = f.+

The probability of at most one basketball being non-conforming in a random sample of 10 basketballs, assuming a population proportion of 10%, is approximately 0.7361 or 73.61%.

We first need to know the proportion of non-conforming basketballs in the population. Let's assume that it is 10%.

Using this information, we can calculate the probability of at most one basketball being non-conforming using the binomial distribution formula:

P(X ≤ 1) = P(X = 0) + P(X = 1)

Where X is the number of non-conforming basketballs in our sample.

P(X = 0) = (0.9)¹⁰ = 0.3487

P(X = 1) = 10C1(0.1)(0.9)⁹ = 0.3874

(Note: 10C1 represents the number of ways to choose one non-conforming basketball from a sample of 10.)

Therefore, P(X ≤ 1) = 0.3487 + 0.3874 = 0.7361

Since we don't have any information about the probability of A and B occurring together, we cannot use the formula directly. However, we can use the fact that P(B) = P(A and B) + P(A and B complement), which implies that P(A and B complement) = P(B) - P(A and B).

Substituting the given probabilities, we have:

P(A and B complement) = P(B) - P(A and B) = 0.6 - (0.2 x P(B|A))

We don't know the value of P(B|A), but we can use the fact that P(A and B) = P(A) x P(B|A) to rewrite the equation:

P(A and B complement) = 0.6 - (0.2 x P(A) x P(B|A))

Substituting the given probabilities, we have:

The equation for the function g(x) in terms of the function f(x) is g(x) = -3f(x - 1) + 5.

Given a function f(x).

This function has been reflected over the x-axis, been stretched vertically by a factor of 3, and translated 1 unit right and 5 units up.

The resulting function is g(x).

When f(x) is reflected over the x-axis, the new function, say f'(x) will be of the form -f(x).

f'(x) = -f(x)

Then the function f'(x) is been stretched vertically by a factor of 3.

This will result in the function f''(x),

f''(x) = 3 f'(x) = 3 (-f(x)) = -3f(x)

Then this function f''(x) is translated 1 unit right and 5 units up.

When translated k units right, a function f(x) becomes f(x - k) and when translated k units up, a function f(x) becomes f(x) + k.

Then the resulting function is,

g(x) = -3f(x - 1) + 5

Hence the function g(x) is g(x) = -3f(x - 1) + 5.

Therefore, we have proven the identity sin(x - π/2) = -cos(x) using the subtraction formula for sine and simplifying the expression.

The subtraction formula for sine is a trigonometric identity that relates the sine of the difference of two angles to the sines and cosines of the individual angles. It states that:

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

where a and b are any two angles.

In the given identity sin(x - π/2) = -cos(x), we can use this formula by setting a = x and b = π/2. This gives us:

sin(x - π/2) = sin(x)cos(π/2) - cos(x)sin(π/2)

Using the values of cos(π/2) and sin(π/2), we simplify this to:

sin(x - π/2) = sin(x)(0) - cos(x)(1)

sin(x - π/2) = -cos(x)

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

Setting a = x and b = π/2, we have:

sin(x - π/2) = sin(x)cos(π/2) - cos(x)sin(π/2)

Since cos(π/2) = 0 and sin(π/2) = 1, we can simplify this expression to:

sin(x - π/2) = sin(x)(0) - cos(x)(1)

sin(x - π/2) = -cos(x)

For SKUs with variable demand, unknown demand, or seasonal demand, other inventory management models, such as the periodic review model or the continuous review model, may be more appropriate.

The fixed order interval EOQ (Economic Order Quantity) model is best used for SKUs with stable demand.

The EOQ model is a mathematical approach to find the optimal order quantity that minimizes the total inventory costs, including ordering costs and holding costs. The fixed order interval EOQ model assumes that the demand rate is constant, and the lead time is fixed and known.

what is constant?

In mathematics and science, a constant is a fixed value that does not change. It is a quantity that remains the same throughout a given problem or system, and it can be represented by a symbol or a numerical value.

Jade and Juliette need to ride for approximately 45 more days, at a rate of 62 miles per day, to complete their trip promoting autism awareness.

To determine how many more days Jade and Juliette need to ride their bikes to complete their trip, we can create an equation using the given information.

Let's denote the number of days they need to ride after the first two days as D.

The distance covered on the first day is 45.4 miles, and the distance covered on the second day is 56.3 miles. Therefore, the total distance covered on the first two days is:

Total distance covered on the first two days = 45.4 + 56.3 = 101.7 miles

The remaining distance they need to cover to complete their trip is 2,878 - 101.7 = 2776.3 miles.

Since Jade and Juliette plan to ride 62 miles per day from now on, we can create the equation:

62 * D = 2776.3

Dividing both sides of the equation by 62:

D = 2776.3 / 62

D ≈ 44.83

Rounding up to the nearest whole number, we find that Jade and Juliette need to ride for approximately 45 more days to complete their trip.

The integral of the function f(x) = x sec^2(t) dt/4 is given by F(x) = (x/4)tan(t) + C, where C is the constant of integration.

To find the integral of f(x), we can apply the integration rules. First, we rewrite the function as [tex]f(x) = (x/4)sec^2(t)[/tex]. We can pull out the constant factor of x/4 from the integral. Therefore, the integral becomes (1/4) x ∫ sec²(t) dt.

The integral of [tex]sec^2(t)[/tex] with respect to t is tan(t), so the integral becomes (1/4) x tan(t) + C, where C is the constant of integration. Now, we have the antiderivative of f(x).

Since the original function had a variable t, the resulting antiderivative also contains t. We haven't been given any specific limits for the integration, so the solution is expressed in terms of t. If specific limits were provided, we could evaluate the definite integral and obtain a numerical value.

In summary, the integral of [tex]f(x) = x sec^2(t) dt/4[/tex] is [tex]F(x) = (x/4)tan(t) + C[/tex], where C represents the constant of integration.

Find the natural cubic spline, we need to construct a piecewise cubic polynomial that passes through each data point and has continuous first and second derivatives. The natural cubic spline that interpolates the given data points f(0) = 0, f(1) = 1, and f(2) = 2 can be determined.

To find the natural cubic spline, we need to construct a piecewise cubic polynomial that passes through each data point and has continuous first and second derivatives.

In this case, we have three data points: (0, 0), (1, 1), and (2, 2). We can construct a natural cubic spline by dividing the interval [0, 2] into two subintervals: [0, 1] and [1, 2]. On each subinterval, we define a cubic polynomial that passes through the corresponding data points and satisfies the continuity conditions.

For the interval [0, 1], we can define the cubic polynomial as

s1(x) = a1 + b1(x - 0) + c1(x - 0)^2 + d1(x - 0)^3,

where a1, b1, c1, and d1 are the coefficients to be determined.

Similarly, for the interval [1, 2], we define the cubic polynomial as

s2(x) = a2 + b2(x - 1) + c2(x - 1)^2 + d2(x - 1)^3,

where a2, b2, c2, and d2 are the coefficients to be determined.

By applying the necessary calculations and solving the system of equations, we can determine the coefficients of the cubic polynomials for each interval. The resulting natural cubic spline will be a function that satisfies the given data points and exhibits a smooth interpolation between them.

Since the given data points f(0) = 0, f(1) = 1, and f(2) = 2 define a simple linear relationship, the natural cubic spline interpolating these points will be a straight line passing through them.
