No, 1 1 2 3 5 8 is not an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a constant to the previous term.

Thus, the difference between successive terms is the same. In the given sequence, the difference between terms 1 and 2 is 0, between terms 2 and 3 is 1, between terms 3 and 5 is 2, and between terms 5 and 8 is 3. Therefore, the difference between successive terms is not the same and hence, 1 1 2 3 5 8 is not an arithmetic sequence.

The constant of proportionality for respective problems is 2/7, 15, 2.75, 13, 4/3.

A) In the first block,

Using points we can find the equation of line ,

Using the formula (y - y₀) = m (x - x₀)

where m is the slope of the equation

The equation of line becomes 2x = 7y

⇒ y = 2/7x

⇒ 2/7 is the constant of proportionality

B) From the graph given,

Again Using the formula (y - y₀) = m (x - x₀)

If we consider two points,

(2,30) and (4,60)

The equation of line becomes

15x = y

Here, the constant of proportionality is 15.

C) It is given the equation is y = 2.75x

The constant of proportionality here is 2.75

D) It is given that,

The price of 5 games is $65.00

The price of 1 game will be 65 / 5

= $13.00

The equation becomes

y = 13x

So, the constant of proportionality becomes 13.

E) Let us consider 2 points (3,12) and (6,24)

The equation of line using the formula (y - y₀) = m (x - x₀) becomes 4x = 3y

⇒ y = 4/3 x

The constant of proportionality becomes 4/3.

The residual square sum may equal 0. Your model will fit your data more closely if the residual sum of squares is small; conversely, if the residual sum of squares is large, your model will match your data less closely. A value of 0 indicates that your model fits the data perfectly.

What Exactly Is Residual Value?

The estimated value of an asset that is fixed at the end of its useful life or lease term is its residual value, which is often referred to as salvage value. In lease agreements, the residual value is one of the lessor's main methodologies for calculating the lessee's periodic lease payments.

A good residual value is what?

Check out the Car Lease Ratings section of our Lease Kit for a complete list of high-residual vehicle brands and models.

                   A car is probably not a good lease deal if the lease-end residual value is less than 50% of the MSRP (for a 36-month lease). 55% to 65% of MSRP would be a nice residual.

Explanation:

The legs of any right triangle are always perpendicular. They meet up to form a right angle, aka 90 degree angle.

The line y = 2x+4 goes through (2,8). This can be confirmed with a graph. Or note how plugging x = 2 leads to y = 8.

Therefore, y = 2x+4 forms one of the legs of this triangle.

The slope here is 2 = 2/1; the negative reciprocal is -1/2 = -0.5, which is the slope of the perpendicular line. We want this line to go through (2,8)

So,

y = mx+b

8 = -0.5*2+b

8 = -1+b

8+1 = b

9 = b

b = 9

The equation of the perpendicular line is y = -0.5x+9

Replace -0.5 with the fraction -1/2 if needed.

Dilation is a type of transformation in geometry that changes the size of a shape without changing its orientation. When a shape is dilated by 1 2, it means that the shape is multiplied by a factor of 1 2.

This means that the shape is made half of its original size. The shape will be reduced to one-half of its original area and its perimeter will be halved as well. When a shape is dilated by a factor greater than 1, it will be expanded; when a shape is dilated by a factor less than 1, it will be reduced.

When a shape is dilated by 1 2, the center of dilatation is the same as the original shape's center of dilation. The scale factor of the dilation is 1 2, so the coordinates of the center of dilation will not change.

Based on the information provided, the price of each DVD is $11.

To calculate the price of the DVD, two main variables must be considered:

Tax is a compulsory amount that is levied on goods and services by the government. Tax serves as a form of transfer of wealth from the private individuals to the government.

Taxes increase the cost of a good or service.

Now, let's calculate the cost of each DVD:

The price of each DVD = (total cost - tax) / number of DVDs bought

The price of each DVD = (61 - 6) / 5

The price of each DVD = 55 / 5

The price of each DVD = $11

Based on this, the price of each DVD was $11, you can double-check this below

The behavior of the graph relative to the x axis can be described by the equation of the line.

The equation of a line is y = mx + b, where m is the slope and b is the y-intercept. The slope of a line represents the rate of change of the graph with respect to the x axis; a positive slope indicates the graph is increasing, while a negative slope indicates it is decreasing. The y-intercept is the point at which the line crosses the y axis. For example, if the equation of the line is y = 2x + 4, then the slope of the line is 2, meaning the graph increases by 2 units every time the x axis increases by 1 unit, and the y-intercept is 4, meaning the line crosses the y axis at the point (0, 4). By analyzing the equation of the line, you can determine the behavior of the graph relative to the x axis.

The value of x in the equation 8 (x - 3) + 7 = 2x (4 - 17) is x = 1/2.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side

The given equation is,

8 (x - 3) + 7 = 2x (4 - 17)

Distributive property : p (q + r) = p q + p r

Applying the property here,

8x - (8 × 3) + 7 = 2x × (-13)

8x - 24 + 7= -26x

8x - 17 = -26x

8x + 26x = 17

34x = 17

x = 17/34

x = 1/2

Jon should solve for y in the first equation because the coefficients can be reduced by a common factor to eliminate the coefficient of y.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Given linear equations are,

6x + 3y = 27

5x + 2y = 21

The coefficients of the first equation are multiples of 3.

Hence dividing throughout the first equation by the common factor 3, coefficient of y will be eliminated.

6x/3 + 3y/3 = 27/3

2x + y = 9

y = 9 - 2x

Solving by substitution, the second equation becomes,

5x + 2(9 - 2x) = 21

5x + 18 - 4x = 21

x = 3

y = 9 - 2x = 3

The solution of the partial differential equation 7.7.2 is given by

u(x,t) = t^2 sin(2πx) + c,u(0.3,1.5) = 1.96 + c, where c is an arbitrary constant.

Partial differential equations are mathematical equations used to describe how a function changes as its inputs change. The equation 7.7.2 is a linear second order partial differential equation in two independent variables. It has the form of a generalized wave equation, in which a wave propagates through a medium with varying physical properties.

To calculate partial differential equations u(x,t) for given values of x and t:

Let x = 0.3 and t = 1.5

Substituting these values into the equation, we get:

u(0.3,1.5) = (1.5)^2 sin(2π(0.3)) + c

= 2.25 sin(0.6π) + c

= 2.25(0.87) + c

If the model train is 57 cm long, then 266 m is the length of real train.

In the given question, a model train has a scale of 3 cm : 14 m.

If the model train is 57 cm long, then we have to find how long the real train is.

The scale of model train is 3 cm :  14 m.

Now firstly convert m in cm. As we know that 1 m = 100 cm

Now, the scale of model train is 3 cm :  1400 cm.

The length of the model train is 57 cm.

So in the scale of the model train 3 cm = 57 cm

Now the scale of the model train 1 cm = 19 cm

Now find the length of the real train by multiplying the 1400  by 19 because in the scale of 1 cm is equal to the 19 cm.

So, the length of the real train = 1400 × 19

The length of the real train = 26600 cm
