25 points no I need help with math

1. 23.55 in

2. 102.36 mm

Step-by-step explanation:

First, the circumference of a circle is written as: , where either equivalence works and d = diameter and r = radius.

1. We know that d = 7.5, so we just plug this into the equation:

Thus, the circumference is 23.55 inches.

2. We know here that r = 16.3, so we can plug this into the other equivalence:

≈

Thus, the circumference is 102.36 millimeters.

Hope this helps!

1. 23.55 inches

2. 102.36 millimeters

Step-by-step explanation:

1. Circumference = pi × d

3.14 × 7.5

= 23.55 in

2. Circumference = 2pi × r

2 × 3.15 × 16.3 = 102.364 mm

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
