Answer:
see explanation
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
Given A = 55 , then
s² = 55 ( take the square root of both sides )
s = 
≈ 7 in ( to the nearest whole inch )
s ≈ 7.4 in ( to the nearest tenth of an inch )
This is the answer that I came out with. Hope it helps.
Answer:
x = 8√5
Step-by-step explanation:
for right triangle
c^2 = a^2 + b^2
with c is the hypotenuse; a & b are the other sides
(4 + 16)^2 = (4√5)^2 + x^2
400 = 80 + x^2
x^2 = 320
x^2 = 64(5)
√x^2 = √64(√5)
x = 8√5
Answer:
y=45000(1-0.03)^x
Step-by-step explanation:
1) the exponential decay formula is
y=c(1-r)^x
where c= starting amount
r=rate of change
x=time
so
y=45000(1-0.03)^x
y=45000-1350x
