Answer:

Step-by-step explanation:

For many "mixture" problems, it is convenient to use a variable for the quantity of the highest contributor. Here, we can use 'a' to represent the number of adult tickets, because adult tickets cost the most. Then the number of student tickets is (a+25), and the total revenue is ...

  6a +3(a+25) = 660

  9a +75 = 660

  9a = 585

  a = 65

  (a+25) = 90

The drama class sold 90 student tickets and 65 adult tickets.

Shape P is translated to shape Q using b[tex]\left[\begin{array}{ccc}7\\4\end{array}\right][/tex]..

In mathematics, a translation is the up, down, left, or right movement of a shape. Because the translated shapes appear to be exactly the same size as the original ones, they are congruent with one another.

Given:

The shape P is mentioned on the graph is translated to shape Q.

So, the shape shifted 7 units to left.

and, the shape needs to shift downwards 4 places.

Hence, the required vector is [tex]\left[\begin{array}{ccc}7\\4\end{array}\right][/tex].

cos(2θ) + sin²(θ) = 0

Half-angle identity:

cos(2θ) + (1 - cos(2θ))/2 = 0

Simplify:

2 cos(2θ) + 1 - cos(2θ) = 0

cos(2θ) = -1

Solve for θ :

2θ = arccos(-1) + 2nπ

2θ = π + 2nπ

θ = π/2 + nπ

Answer:

f(g(4)) = -2

Step-by-step explanation:

First, find g(4) by plugging in 4 as x into the function:

g(x) = 2x - 3

g(4) = 2(4) - 3

g(4) = 8 - 3

g(4) = 5

f(g(4)) can be found by finding f(5), since g(4) = 5

Find f(5) by plugging in 5 into the function:

f(x)= x - 7

f(5) = 5 - 7

f(5) = -2

So, f(g(4)) = -2

Answer:

P = 2288 W

Step-by-step explanation:

The power, P (watts), of a car engine is proportional to the square of its speed i.e.

[tex]P\propto s^2[/tex]

or

[tex]P=ks^2[/tex]

Put s = 35, P = 1760 to find k.

[tex]k=\dfrac{P}{s^2}\\\\k=\dfrac{1760}{35^2}\\\\k=1.43[/tex]

Now put k = 1.43 and s = 40. So,

[tex]P=1.43\times (40)^2\\\\P=2288\ W[/tex]

So, the new power is 2288 W when the speed is 40 m/s.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(4, 5) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 5 = 20. In the next intermediate step the fraction result cannot be further simplified by canceling.

Answer:

  48

Step-by-step explanation:

Evaluate each of the functions by putting the number where x is.

  [tex]g(x)=x^2-4\\\\g(-7)=(-7)^2-4=49-4\\\\\boxed{g(-7)=45}\\\\f(x)=x+4\\\\f(-7)=-7+4\\\\\boxed{f(-7)=-3}[/tex]

Then the difference is ...

  g(-7) -f(-7) = 45 -(-3) = 45 +3 = 48

Answer:

solution given;

g(x)=x²-4

f(x)=x+4

Now

g(-7)-f(-7)=(-7)²-4-(-7+4)=49-4+3=48

Answer:

y = -1/2x + 4

Step-by-step explanation:

to answer this question you need to find the slope and the y-intercept

to find the slope of a line that is perpendicular to another line you take the opposite and reciprocal of the slope of the first line

in this case the slope of the initial line is 2; therefore, the opposite reciprocal is -1/2

knowing slope ('m') = -1/2 and having the point (-2, 5) can give us the y-intercept of the new line; we start with:

y = mx + b  and then plug the values in so find the y-intercept ('b')

5 = (-1/2)(-2) + b

5 = 1 + b

b = 4

put it all together:  y = -1/2x + 4

Answer:

B) Exp. Decay

Step-by-step explanation:

Because the term getting raised to a power is under 1, the function immediately starts going down and approaches negative infinity as x approaches infinity.

The type of function is f(x)=2(1/7)^x is Exponential Decay, the correct option is B.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

Function; f(x)=2(1/7)^x

Now,

The function has the form f(x)=abx

where a and b are constants and b is between 0 and 1. In this case, a is 2 and b is 1/7, which is less than 1. This means that the function decreases as x increases.

Therefore, by the given function the answer will be Exponential Decay.

Step-by-step explanation:

Given the parent function " y = ∛x" we know that the first graph should have a vertical shift down 2 units, and a horizontal shift 4 units to the right. There is no vertical stretch since there is no coefficient. (Check first graph)

Domain: - ∞ < x < ∞

Step-by-step explanation:

because 3times the cups is 36

so four times more 36

There are 13 cups of flour in this recipe when Katie uses 12 cups of flour and sugar to make cookies. The amount of flour is four more than three times the amount of sugar.

Let's assume the amount of sugar used in the recipe is represented by the variable "s."

According to the given information, the amount of flour used is four more than three times the amount of sugar. In mathematical terms, this can be expressed as:

Flour = 3s + 4

Now, we know that Katie uses 12 cups of flour in the recipe. We can set up an equation to solve for the amount of sugar:

12 = 3s + 4

Subtracting 4 from both sides of the equation:

12 - 4 = 3s

8 = 3s

Dividing both sides by 3:

8/3 = s

s = 2.67

Since the number of cups of sugar must be a whole number, we can round the value to the nearest whole number. Thus, s ≈ 3.

Now, we can find the amount of flour by substituting the value of sugar into the equation:

Flour = 3s + 4

Flour = 3(3) + 4

Flour = 9 + 4

Flour = 13

Therefore, there are 13 cups of flour in this recipe.

Step-by-step explanation:

A polynomial written in standard form would be written in such a way that the term with the highest degree comes first, followed by the second highest and so on, then what comes last is the constant.

Given the polynomial -7x³ - 1 - ⅑x, -7x³ with the highest degree comes first, followed by -⅑x, and then the constant, -1, comes last.

Thus, we would have:
