Question

After a baby was born, he began to gain weight at a rate of 2 pounds per month. The weight of the baby at birth was 10 pounds. write an equation for W, in terms of t, representing weight, in pounds, of the newborn baby tt months after birth.

Answer 1

Answer:

$W(t) = 2t$

Step-by-step explanation:

Given

Weight = 2 pounds

Rate = monthly

Required

Determine the weight of the baby in t months

When the baby is 1 month old, t = 1;

$Weight = 2\ pounds * 1$

$Weight = 2\ pounds$

When the baby is 2 months old, t = 2;

$Weight = 2\ pounds * 2$

$Weight = 4\ pounds$

When the baby is t months old;

$Weight = 2\ pounds * t$

$Weight = 2t\ pounds$

Represent Weight as a function of t

$W(t) = 2t$

Hence, the formula is $W(t) = 2t$

Answer 2

Answer:

2t+8
