I think its idfk…maybe?!?
Step-by-step explanation:
Firstly, we'll try to simplify the integrand. By hint 1, we see that:

Simplifying the integrand gives us:

Next, by hint 2, we observe that:

So this tells us to make the substitution: 
Doing so gives us:
, which should be trivial.
Answer:
i think D) x > -21 is answer
Answer:
What is part 1?
Step-by-step explanation:

A=futurer amount
P=present amount
r=rate in decimal
n=number of times compounded per year
t=time in years
A=2500
r=0.05
n=2
t=2




divide both sides by [tex} 1.025^{4} [/tex]
2264.88=P
