Note that if the area of any figure is multiplied by a factor of a.

The perimeter will be multiplied by √a

From the problem, the are of the square is multiplied by 1/9, so we need to get the square root of that factor to get the factor for the perimeter.

Therefore, the answer is C. multiplied by 1/3

Remember that to model this kind of problems, we can use the equation of a straight line

Where:

• b, are the fixed costs

• x ,represents what varies

• m, is the cost of what varies

1. Therefore, using the data provided, we can model the cost of production with a function where:

• x ,is the numbers of CD's produced

• C, is the cost of producing those CD's

2. To model the revenue, we'll have to take into account that every CD sells at $68. Therefore, the money collected by selling the x CD's produced is:

Where:

• x ,its the number of CD's produced and sold

• R, is the total revenue

3. To get the profit, we'll have to substract the production cost to the money collected by the sale. Remember we already have two expressions, in terms of x, that describe both situations. Therefore,

Where:

• x ,its the number of CD's produced and sold

• P, is the total revenue

4. In order to break even, the revenue (R) has to be equal to the cost of production (C), Thus,

Therefore, 546 CD's would have to be produced to break even.

The image of the point (-4, -1) after the translation is:

(-3, 1)

A translation:

Tᵃ'ᵇ applied to a point (x, y) gives:

Tᵃ'ᵇ(x, y) = (x + a, y + b).

In this case, we know that:

Tᵃᵇ(1, 1) = (1 + a, 1 + b) = (0, 3)

Then:

1 + a = 0

1 + b = 3

Solving these we get:

a = 1

b = 3 - 1 = 2

The translation is:

T¹'²

Applying this to the point (-4, -1) gives:

T¹'²(-4, -1) = (-4 + 1, -1 + 2) = (-3, 1)

The original equation is:

5 x^2 + (10 x^2 + 10) = 3 x^2 - 5

The first step the person did was:

15 x^2 + 10 = 3 x^2 - 5

so in this first step the person used the associative property of addition by associating 5 x^2 with 10 x^2 and combining them to give 15 x^2.

The rate at which the sloth travels as required in the task content is; -22ft/min.

It follows from the task content that the rate at which the sloth travels is to be determined.

Since the correct representation of the data is such that the distance and corresponding time pairs are as follows;

(98, 1) , (76, 2) , (54, 3), (32, 4).

Hence, the rate of distance change per time is the speed of the sloth and hence, the rate of distance change is;

Rate = ∆Distance/∆time.

Rate, R = (98 - 76)/(1 - 2)

Rate, R = 22/-1

R = -22 ft/min.

Ultimately, the rate at which the sloth travels is therefore; -22 ft/min.

The scale factor K = 0.9 is smaller than 1, so this is a reduction.

If we have a dimension L, a change of scale of scale factor K gives the new length: K*L

Then:

if K > 1, we have an enlargement.

if K = 1, we have a preservation (nothing changes)

if  0 < K < 1, we have a reduction.

In this case, we have K = 0.9, this is smaller than 1, so we have a reduction.

By applying line ratio, the coordinates of P are: [10, 8].

Mathematically, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical expression:

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

Given the following parameters:

Substituting the given parameters into the formula, we have;

P(x, y) = [(mx₂ + nx₁)/(m + n)],  [(my₂ + ny₁)/(m + n)]

P(x, y) = [(3(12) + 1(4))/(3 + 1)],  [(3(9) + 1(5))/(3 + 1)]

Option C gives the graph of Function g is a transformation of the parent cosine function such that g(x) = 3 cos(x + 2) + 1 as it the graph of cosine function.

The ratio between the adjacent side and the hypotenuse is known as the cosine function (or cos function) in triangles. One of the three primary trigonometric functions, cosine is the complement of sine (co+sine) and one of the three main trigonometric functions.

A graph is a structure that resembles a set of objects in mathematics, more specifically in graph theory, in which some pairs of the objects are conceptually "related." The objects are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Choice C provides a graph of the parent cosine function is transformed into function g such that g(x) = 3 cos(x + 2) + 1 on the cosine function graph.

What is system of linear equations?

A System of Linear Equations is when we have two or more linear equations working together.

Let [tex]x[/tex] be number of children and [tex]y[/tex] be number of adults.

Since [tex]2000[/tex] people enter the zoo then [tex]x+y=2000.[/tex]

The admission fee at a local zoo is $ [tex]1.50[/tex] for children and $ [tex]5.00[/tex] for adults and $[tex]7550.00[/tex] collected then [tex]1.5x+5y=7550[/tex].

Thus there are two linear equations to solve.

Substitute [tex]x=2000-y[/tex]  in  [tex]1.5x+5y=7550.[/tex]

[tex]1.5(2000-y)+5y=7550[/tex]

[tex]3000-1.5y+5y=7550[/tex]

[tex]3000+3.5y=7550[/tex]

[tex]3.5y=7550-3000[/tex]

[tex]3.5y=4550[/tex]

[tex]y=\frac{4550}{3.5}[/tex]

[tex]y=1300[/tex]

So [tex]x=2000-y=2000-1300=700.[/tex]

Therefore there are [tex]700[/tex] children and [tex]1300[/tex] adults.

for the square root you must look for a number that multiplied with itself gives you the indicated value

for this case a number that multiplied by itself gives you 100

sothe square root of 100 is:

The polynomial is f(x) = x³ - 12x² + 64x + 128

Given,

The polynomial has 4, 4-4i, and 4+4i as its roots.

f(-1) equals -255

We have to find a polynomial of degree 3.

If x = 4 is a root, then:

(x - 4) is a factor of the polynomial.

If x = 4 - 4i is a root,

Then,

(x - 4 + 4i) is a factor of the polynomial.

If x = 4+4i is a root.

Now,

(x - 4 - 4i) is a factor of the polynomial.

All the three roots are of the same polynomial.

So,

The polynomial is the product of these factors.

f(x) = k(x - 4) (x-4+4i) (x-4-4i)

f(x) = k(x - 4) [(x-4)² - (4i)²]

f(x) = k(x- 4) [x² + 16 - 8x + 16]

f(x) = k(x - 4) [x² - 8x + 32]

f(x) = k[x³ - 8x² + 32x - 4x² + 32x - 128]

f(x) = k[x³ - 12x² + 64x + 128]

Now find "k", we know that f(-1) = -255.

f(-1) = k[(-1)³ - 12(-1)² + 64(-1) + 128]

-255 = k[-1 - 12 - 64 + 128]

-255 = k × -255

k = 1

That is, the polynomial is f(x) = x³ - 12x² + 64x + 128
