If the interest earned for 4 years = $360, then the interest earned for 1 year would be $90 ($360/4). The interest rate would be 9% (or .09) which can be calculated by 90/1000=.09
You can use the Pythagoras theorem for this since a right triangle is formed.

C = 12
A = 4
B = x
Input values:





So, about 11ft.
Answer:
Step-by-step explanation:
(-1, 1) (1, -3)
(-3 - 1)/(1 + 1)= -4/2 = -2
y - 1 = -2(x + 1)
y - 1 = -2x - 2
y = -2x - 1
answer is A
Circles will never have a side but they only have 1 line that can be counted as a side.
