Question 501545
Male caloric needs. The number of calories needed each day by a moderately active man who weighs w kilograms, is h centimeters tall, and is a years old can be estimated by the polynomial
19.18w + 7h − 9.52a + 92.4.
One of the authors of this text is moderately active, weighs 87 kg, is 185 cm tall, and is 59 yr old.
 What are his daily caloric needs?
Let c = calories needed
c = 19.18w + 7h − 9.52a + 92.4
w = 87, h=185, a=59
so we have:
c = 19.18(87) + 7(185) − 9.52(59) + 92.4
c = 2668.66 + 1295 + 561.68 + 92.5
c = 4617.84 calories

26.Divide and check:
t^2-13/t-4
Set up the problem like this and use long division
:
......._______________
(t-4)|x^2 + 0x - 16
:
You should get (x+4) remainder 3/(x-4)
