3 is 6 less than its square.
3^2 = 9
9-3 = 6
I hope this helps!
To solve this we are going to use the compound interest formula with periodic deposits:
where
is the final amount after
years
is the initial investment
is the periodic deposits
is the interest rate in decimal form
is the number of times the interest is compounded per year
is the time in years
Since he is going to save from 27 years old until 65 years old,
. We know that hes is opening his IRA with $0, so
; We also know that he is going to invest $200 at the beginning of each month, so
. To convert the interest rate to decimal form, we are going to divide it by 100:
, and since the interest is compounded monthly,
. Lets replace all the values in our formula to find
:
We can conclude that Rick will have $157,419.04 in his IRA account by the time when he retires.
Problem One
Test it.
a^2 + b^2 = c^2
a = 8
b = 12 What will c calculate to be.
8^2 + 12^12 = c^2
c^2 = 64 + 144
c^2 = 208
If 18 is to be the hypotenuse of the triangle c^ must equal 324.
208 is nowhere's near that amount.
Mario is right.
Question Two
The only way Hank will be right is if 26 is the hypotenuse. If that is so, the third side is 24. This is how you do it.
a^2 + b^2 = c^2
c = 26
a = 10
10^2 + b^2 = 26^2
100 + b^2 = 676 Subtract 100
b^2 = 676 - 100
b^2 = 576
b = sqrt(576)
b = 24
If 26 is not the hypotenuse, the right triangle cannot be drawn.
Times the answer by the number you divide too and if your answer is correct then we'll done if your answer was wrong check it again
