Answer:
Step-by-step explanation:
In the first part, we are given the function:

Suppose we make x = tan θ
Then dx = sec² θ.dθ


Since; sec² θ - tan² θ = 1
sec² θ = 1+ tan² θ

∴


Thus; In the first part, Use x = tan θ, where
, since the integrand comprise the expression 
From the second part by using substitution method;

Answer:
100.5 inches approximately
Step-by-step explanation:
2πr = circumference
r=16
3.14*16*2=100.48
Answer:
n = 1
Step-by-step explanation:
2n-10 = -8
Then add 10 to both sides
2n = 2
Divide both sides by two
n = 1
Step-by-step explanation:
45+45
90
I guess is the answer
Hello,
y=35*6^x
==>ln(y)=ln(35)+x*ln(6)
==>e^ln(y)=e^(ln(35)+x*ln(6))
==>y=35*ln(6)*e^x≈62.711*e^x
