Answer:
The Base is 150 and the Exponent is 4
The answer is either the first or second if u can put 2 down then both
L x W = 105
L + W = 26 so L = 26 - W
substitute L = 26 - W into L x W = 105
(26 - W) x W = 105
26W - W^2 = 105
W^2 - 26W + 105 = 0
(W - 21)(W - 5) = 0
W - 21 = 0; W = 21
W - 5 = 0; W = 5
The the dimensions of the rectangle are 5 ft and 21 ft.
Double check:
The sum of the length and the width is 26 feet: 21 + 5 = 26 feet
A rectangle has an area of 105 square feet: 21 x 5 = 105 square feet
Answer:
$29,721
Step-by-step explanation:
We have been given that Wyatt is investing money into a savings account that pays 2% interest compounded annually, and plans to leave it there for 15 years. We are asked to find the amount deposited by Wyatt in order to have a balance of $40,000 in his savings account after 15 years.
We will use compound interest formula to solve our given problem.
, where,
A = Final amount after T years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
T = Time in years.
Let us convert our given interest rate in decimal form.

Upon substituting our given values in compound interest formula, we will get:




Switch sides:



Upon rounding our answer to nearest dollar, we will get:

Therefore, Wyatt will have to invest $29,721 now in order to have a balance of $40,000 in his savings account after 15 years.
