Question

A young sumo wrestler decided to go on a diet yo go on a special high protein diet to gain weight rapidly.he started at 90 kilograms and gained weight at a constant rate.after 8 months ,he weighed 138 kilograms. Let W(t) denote the sumo wrestlers W as a function of time. Write the functions formula

Answer 1

48 kilo.÷8 months is the correct formula to this answer

Answer 2

$W(t) = 6t+90$; you first need to find out how much he'll gain in one month. If he went from 90 kg to 138, you should subtract $138-90=48$. This means he gains 48 in 8 months. Next, you should divide $48/8=6$, so he gains 6 kg/month. Since he starts out with 90 kg, 90 is the y-intercept. $t$ will equal the time in months, and the slope is $\frac{6}{1}$-- or $W(t) = 6t+90$.
