Answer:
Step-by-step explanation:
The amount (A) in a deposit after 1 year is calculated as follows:
A = P*(1 + r)
where:
P is the present value
r is the annual rate (decimal)
After the first year:
A = 300*(1 + 0.055) = $316.5
After the second year, the account will have a new amount of $316.5 due to the new $300 and the interest gained with the previous $316.5:
A = 316.5 + 316.5*(1 + 0.055)
After the third year:
A = 316.5 + [316.5 + 316.5*(1 + 0.055)]*(1 + 0.55)
A = 316.5 + 316.5*(1 + 0.055) + 316.5*(1 + 0.055)^2

Given that the shape of the satellite looks like a parabola
The equation of parabola is given as follows
Where
a= 13
Therefore
Lets take (13 , y) is a
Now by putting the values in the above equation we get
y=3.25 in
Therefore the depth of the satellite at the nearest integer will be 3.3 inches.
Depth = 3.3 inches
