Answer:

Step-by-step explanation:

h(-7) just means that inside the x value, you replace the x with a -7.

h(-7) = |3x| - 1

h(-7) = | 3(-7)| - 1

h(-7) = | -21 | - 1

NOTE: -21 is inside |x|, those straight lines mean absolute value. No matter what, any negative number would turn into a positive one. And if it’s posititve, then it stays positive.

h(-7) = 21 - 1

h(-7) = 20

A vat of milk has spilled on a tile floor. The milk flow can be expressed with the function r(t) = 4t, where t represents time i

Likurg_2 [28]

R(t) = 4t
A(r) = π(r^2)

a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)

b) t = 4,

A(4) = 16*3.14*(16)^2 = 12,861.44
