First do the educations on the sides then add them unless you’re finding the area then multiply xoxo
Answer:
Step-by-step explanation:
2^-3=1/2^3
3^-2=1/3^2
(2^-3)(3^-2)=1/72
Formula for Riemann Sum is:

interval is [1,3] so a = 1, b = 3
f(x) = 3x , sub into Riemann sum

Continue by simplifying using properties of summations.

Now you have an expression for the summation in terms of 'n'.
Next, take the limit as n-> infinity.
The limit of

goes to 0, therefore the limit of the summation is 12.
The area under the curve from [1,3] is equal to limit of summation which is 12.
The equation you are looking for is P(1 + r/n)^nt, which is 320,000(1+0.0575)^10 = 559,698
