Ayoung sumo wrestler decided to go on a special diet to gain weight rapidly. w(t), left parenthesis, t, right parenthesis 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? plz me

80 lb

Step-by-step explanation:

Before this wrestler begins his diet, he obviously weighed something.  Look at W(t) =80+ 5.4t  and set t = 0; you get W(0) = initial weight = 80 lb + (5.4 lb/month)(0) = 80 lb.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
