Answer:
Compound Interest= $3440
Final Amount= $5440
Step-by-step explanation:
Compound Interest's formula= P(1+r/100)^n
where P is Principal, r is Rate then n is Years
So in this case,,2000(1+.72)^1 = $3440
Hence, Total Amount = Principal+Interest
therefore T.A= $2000+$3440
T.A=$5440
Thanks... Subjected to Review
4. -8
5. 24
6. I can't see it properly so if it's ÷ answer is 9 if it's - answer is -70
Computing an integral by substitution is the reverse of the chain rule for computing the derivative. Substitution is intended to rewrite a complicated-looking integral involving the derivative of some component expression as another much simpler integral. For example, if 
, then 
and
###
Integration by parts is the reverse of the product rule for derivatives:
Integrating both sides with respect to 
gives

Personally, I think the best way to grasp the idea behind the two methods is to practice. You start to notice patterns to the point where knowing which is the "right" method to use becomes second nature.
<span>If this statement is a True or False question.
Then, TRUE. A "b" value of less than 1 produces a graph with exponential decay.
We consider this formula: y = a*b^x or f(x) =a*b^x
a is the initial value, b is the rate, x is the exponent.
If b has a value of less than 1, as the exponent increases the resulting value of y decreases.
f(x) = 20(0.90)^x
f(1) = 200(0.90)</span>¹ = 180
f(2) = 200(0.90)² = 162
f(3) = 200(0.90)³ = 145.80
f(4) = 200(0.90)⁴ = 131.22
f(5) = 200(0.90)⁵ = 118.10
Exponential decay is the decrease in a quantity. As you can see in the given example the value of f(x) decreases as the value of x increases because the value of b is less than 1.
