Question

A Young sumo wrestlers decided to go on a special diet to gain weight rapidly w (t)=80+5.4t how much weight does the wrestler gain every 2 months

Answer 1

The rate is 5.4 per month so in two months gains 10.8

Answer 2

10.8 kg

Explanation:

We are given that weight of young Sumo wrestler is given by

`w(t)=80+5.4t`

We have to find the weight of wrestler gain in every months.

In order to find the weight gain in 2 month we will find out w(2)

Then, we get

`w(2)=80+5.4(2)`

`w(2)=80+10.8`

`w(2)=90.8`

Weight gain in 2 month=90.8-80=10.8 kg

Hence,the wrestler gain 10.8 kg in every 2 months.
