The answer would be 40
-4(-2) = 8
8(5) = 40
Answer:
Step-by-step explanation:
Given that a bank representative studies compound interest, so she can better serve customers. She analyzes what happens when $2,000 earns interest several different ways at a rate of 2% for 3 years.
a) the interest if it is computed using simple interest. 12.00
=
dollars
b) the interest if it is compounded annually.
=
dollars
c) the interest if it is compounded semiannually
=
d) the interest if it is compounded quarterly.
=
e) the interest if it is compounded monthly.
=
Answer:
50
Step-by-step explanation:
42/n³∑k²+12/n²∑k+30/n∑1
=42/n³[n(n+1)(2n+1)/6]+12/n²[n(n+1)/2]+30/n [n]
=7n(n+1)(2n+1)/n³+6n(n+1)/n²+30
=7(n+1)(2n+1)/n²+6(n+1)/n+30
=[7(2n²+3n+1)+6(n²+n)+30n²]/n²
=[14n²+21n+7+6n²+6n+30n²]/n²
=[50n²+27n+7]/n²
=[50+27/n+7/n²]
→50 as n→∞
because 1/n,1/n²→0 as n→∞
Answer:
7x4=28 there
Step-by-step explanation:
Answer:
Step-by-step explanation:
Rule: never completely trust a diagram that comes with a geometry question. This is a case in point. The "tiny" square is actually much larger than the "larger" square.
If you are trying to find the length of the sides of the squares, the formula is
Area = side^2
3025 = side^2
Take the square root of both sides.
sqrt(3025) = sqrt(side^2)
To find the square root of 3025, do the following
Press √
type in 3025
type in =
You should get 55.
======================
The second square is done the same way
√
90.75
=
And you should get 9.526
