Question

Pls help me i will give the crown thing

Answer 1

Answer:

Given function:

t(s) = 3s + 20

where:

• t(s) = number of palm trees grown
• s = number of seeds planted

Given function:

s(d) = 20d

where:

• s(d) = number of seeds planted per day
• d = number of days

To determine the composite function that represents how many palm trees Carlos can expect to grow over a certain number of days, simply substitute s = 20d into t(s) = 3s + 20:

⇒ t(d) = 3(20d) + 20

⇒ t(d) = 60d + 20

The unit of measurement is how many palm trees Carlos can expect to grow over a certain number of days:

$\sf \dfrac{palm \ trees}{days}$
