Answer:
2730$
Step-by-step explanation:
The amount of money left in the account after n years is given by the equation
where
is the initial amount of money
r is the rate of interest
n is the number of years
In this problem, we have:
is the initial amount of money
is the interest rate (5%)
n = 1 is the number of years
Therefore, the amount of money after 1 year is
Secd(38)
= 1/cosd(38)
= 1/sqrt[1-sind^2(38)] because cos^2(x) + sin^2(x) = 1
cos(30) = sqrt(3)/2 = 0.8660
cos(45) = 0.707
so cos(38) can be assumed to some where around 0.8
= 1/0.8
= 1.25
Therefore D is correct answer
Step-by-step explanation:
You deposit some money into a bank account paying 4% simple interest per year. You received $72 in interest after 3 years. How much the deposit (principal) was?
At start Keenan has x strawberries. He gives Tisha x/2. Then Tisha keeps 4 strawberries and gives Suvi the rest. If y is the number of strawberries that Suvi gets:
y = x/2 - 4.
For example: Keenan has 20 strawberries. He gives Tisha 10 and Tisha gives Suvi 6:
6 = 20/2 - 4
6 = 10 - 4
