Ababy was born and then began to gain weight at a rate of 1.5 pounds per month. after 4 months, the baby's weight was 16 pounds. write an equation for the function w ( t ) , w(t), representing weight, in pounds, of the newborn baby t t months after birth.

W(t) = 10 + 1.5*t

Step-by-step explanation:

Given:

The weight gain of the baby is 1.5 pounds per month.

After 4 months,baby's weight = 16 pounds

Let us the say the weight of the baby when it was born be x.

Then:

x + 1.5*(4) = 16

x = 10

Then weight of the baby as a function of number of months(t) will be=

initial weight + incremental weight per month*no of months(t).

W(t) = 10 + 1.5*t

lockers 1, 4, 9, 16, 25, 40, and 49 are open
