Answer:

  y = -5x³

Step-by-step explanation:

The point of inflection of the parent cubic function f(x) = x³ is at the origin, the same place it is shown on the graph. So, there is no translation involved in creating the graph.

We know the parent function gives f(1) = 1, but here, we have (x, y) = (1, -5). This suggests a vertical scale factor of -5. So, the transformed function is ...

  y = -5x³

The perimeter of the entire figure is 62.8 cm.

Given, that the diameter of the inner semicircles is 9 cm and the width between the outer and inner semicircles is 2 cm.

The radius of the inner semicircle =4.5 cm and the radius of outer semicircle =5.5 cm (∵Diameter=9+2=11 cm)

We need to find the perimeter of the entire figure.

<h3>What is the perimeter?</h3>

A perimeter is a closed path that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.

We know that, the circumference of a semicircle=πr and the circumference of two semicircles=2πr

Thus, the circumference of inner semicircles=2×3.14×4.5=28.26 cm

The circumference of outer semicircles=2×3.14×5.5=34.54 cm

The perimeter of the entire figure=28.26+34.54=62.8 cm

Therefore, the perimeter of the entire figure is 62.8 cm.

sketch the graph of each function. Then State the domain, range and increasing, decreasing intervals. Part 3. ​
Eddi Din [679]

Answer:

19) Domain: - ∞ < x < ∞                    20) Domain:  - ∞ < x < ∞

Range: - ∞ < y < ∞                                  Range: - ∞ < y < ∞

Increases throughout                            Decreases throughout

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 < ∞

Range: - ∞ < y < ∞

Increases throughout

______________________________

For the second graph there should be a vertical shift down three units, a horizontal shift 1 unit to the left, and a vertical stretch by a factor of - 1. (Check second graph)

Domain: - ∞ < x < ∞

Range: - ∞ < y < ∞

Decreases throughout

Find the center and radius of the circle with the equation: a. center: (-5, 1) radius: 4 c. center: (-5, 1) radius: 2 b. center:
damaskus [11]

Answer:

Step-by-step explanation:

if center= (h,k)

radius=r

eq. of circle is (x-h)^2+(y-k)^2=r^2

a.

center= (-5,1)

radius=4

eq. of circle is (x+5)^2+(y-1)^2=4^2

b.

center=(5,-1)

radius=4

eq. of circle is  (x-5)^2+(y+1)^2=4^2

c.

center=(-5,1)

radius=2

eq. of circle is (x+5)^2+(y-1)^2=2^2

d.

center=(5,-1)

radius=2

eq. of circle is (x-5)^2+(y+1)^2=2^2
