Answer:
80kg
Step-by-step explanation:
A young sumo wrestler decided to go on a special diet to gain weight rapidly. W(t) models the wrestler's weight (in kilograms) as a function of time t (in months). W(t)=80+5.4t
What was the wrestler's weight before his special diet?
Again the function is W(t)=80+5.4t,
We know that W is the weight while t stands for time in months
so we can start by using t at 0,3,4
when t=0
W(0)=80+5.4*0=80kg
W(3)=80+5.4*3=96.2kg
W(4)=80+5.4*3=101.6kg
so before his special diet he was 80kg
Answer: 20

20÷1÷[(2)÷2] Do 10÷5 in parenthesis
20÷1÷[(1)] Do (2)÷2
20÷1 Do 1÷[(1)]
20 Do 20÷1, and that is your answer
<span><span>16<span>x^4</span></span>+<span>40<span>x^3</span></span></span>−<span>24<span>x^<span>2
