Answer:

no

Step-by-step explanation:

It does.

5x-2=0

5x=2

x=2/5

(2/5, 0)

is an x-intercept

Select the points that lie on the function g(x) = -x2 (Choose all that apply.) (0, 0) (-3, -9) (3, -9) (-3, 9)
Evgesh-ka [11]
The function is :

                              \displaystyle{ g(x)=-x^2, 

which means that "g of a number" is equal to "negative, the square of that number".

According to the function we calculate g(0), g(-3), g(3) as follows:

g(0)=-0^2=-0=0\\\\g(-3)=-(-3)^2=-9\\\\g(3)=-3^2=-9

This means that we have the points (0, 0), (-3, -9), and (3, -9) lying on the graph of the function.


Answer: (0, 0), (-3, -9), (3, -9)

5) Suppose a slice of a 12-inch pizza has an area of 20 square inches. What is the angle of
devlian [24]

Answer:

The angle of the slice is 63.64 degrees

Step-by-step explanation:

Here in this question, we are concerned with calculating the angle of the slice.

What we should know are as follows;

1. A pizza is a perfect circular shape

2. A 12-inch pizza means the diameter of the pizza is 12 inches and consequently its radius will be 12/2 = 6 inches

3. A slice of a pizza represents a sector of the circle( a sector is part of a circle bounded by 2 radii and an arc)

Mathematically, to calculate the angle of the slice, we simply use the formula for the area of a sector.

Area of sector = theta/360 * pi * r^2

where Area of sector = 20 square inches

theta is the center angle we are looking for

r is the radius of the pizza which is 6 inches

Plugging these values into the area of sector equation, we have

20 = theta/360 * 22/7 * 6^2

20 = theta/10 * 22/7

22 theta = 10 * 20 * 7

theta = 1400/22

theta = 63.64 degrees which is approximately 64 degrees to the nearest degree
