Question

How do you do 5a) and 5b)????? Please help!!!!

Answer 1

`21.0 { { {1221220 = 223jn}^(n \: \: \: \: \: \: \: \: \: \: \: \: \tan( \beta \beta \beta \beta \beta \beta \pi\pi) ) }^(2) }^(2) * (?)/(?)`

Answer 2

31° F and 67° F

Explanation:

(a)

When t = 0 then

f(0) = 31 +
`(0)/(100)` = 31 + 0 = 31° F

(b)

When t = 10 , then

f(10) = 31 +
`(40(10^3))/(10^3+100)` = 31 +
`(40000)/(1100)` = 31 + 36.36... ≈ 67° F
