Help pleaseee!! I put 50

a) 86

b) 12.22222222... or 110/9

Step-by-step explanation:

F(30) = 1.8(30) + 32 = 86

F(C) = 10

10 = 1.8C + 32

-22 = 1.8 C

C = 12.222222222... or 110/9

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

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
