This is a classic example of a 45-45-90 triangle: it's a right triangle (one angle of 90) & two other sides of the same length, which means two angles of the same length (and 45 is the only number that will work). With a 45-45-90 triangle, the lengths of the legs are easy to determine:
45-45-90
1-1-sqrt2
Where the hypotenuse corresponds to sqrt2.
Now, your hypotenuse is 10.
To figure out what each leg is, divide 10/sqrt2 (because sqrt2/sqrt2 = 1, which is a leg length in the explanation above).
Problem: you can't divide by radicals. So, we'll have to rationalize the denominator:
(10•sqrt2)/(sqrt2•sqrt2)
This can be rewritten:
10sqrt2/sqrt(2•2)
=10sqrt2/sqrt4
=10sqrt2/2
=5sqrt2
Hope this helps!!
A = P ( 1+r )^ t
A = the future value including interest
P = the principal = $15,000
r = the annual interest rate = 6% = 0.06
t = the number of years = 5 years
So
A = 15,000(1 + 0.06)^5
A = $20,073.38
Answer
She will have paid $20,073.38 at the end of the five year
Answer:
There is no equal sign.
Step-by-step explanation:
There is no equal sign to make it an algebraic equation.
Answer:
I'm guessing the volume would be 125.66
Step-by-step explanation:
V=πr^2h
π·2^2·10 =
125.66
Not sure how accurate this is, but its been a while since I've done the volume of a cylinder
