A function is given. f(z) = 2 – 5z^2 ;z = -2, z = 0
(a) Determine the net change between the given values of the variable.
(b) Determine the average rate of change between the given values of the variable.

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer: 100

step-by-step explanation:

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
