1. One species of bamboo can grow at an average rate of 60 centimeters per day. Assuming that the
bamboo plant maintains the average rate of
growth per day, how tall will the bamboo plant be
if it grows for:
a. 10 days?

b. 30 days?

c. one-half day?

Show step by step please

Step-by-step explanation:

Given the expression f(t, r) = 13t - 8r²

We are to justify Ava solution at when t = -10 and r = -2

Substitute the given values into the function given;

f(t, r) = 13t - 8r²

f(-10, -2) = 13(-10) - 8(-2)²

f(-10, -2) = 13(-10) - 8(4)

f(-10, -2) = -130-8(4)

f(-10, -2) = -130 - 32

f(-10, -2) = -152

Ava made a mistake in step 4. She added -130 to -8 to get -138 before multiplying by 4 thereby falsifying her result. She must have multiplied -4 by 8 before adding the resulting answer to -130 as shown. Hence the correct answer is -152
