Question

Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 8% each week. The following function represents the weekly weed growth: f(x) = 86(1.08)x. Rewrite the function to show how quickly the weeds grow each day.

f(x) = 86(1.08)7x; grows approximately at a rate of 5.6% daily
f(x) = 86(1.087)x; grows approximately at a rate of 0.56% daily
f(x) = 86(1.01)x; grows approximately at a rate of 0.1% daily
f(x) = 86(1.01)7x; grows approximately at a rate of 1% daily

it is A

Answer 6

so u were correct

Answer 7

thank you

Answer 8

ofc

Answer 9

Politely disagree with A

If the weekly growth rate is 8% (0.08) then the daily growth rate is 0.08/7 = 0.01 or a 1% growth rate

The original exponent is x for weeks, but since we want the new equation in days, we have to multiply weeks by 7 to get 7x as the new exponent
