Answer:
Step-by-step explanation:
first find the area of the circle face.
formula is pi x r² (pi goes on for a long time, this is just rounded!)
so 3.14 x 25 = 78.5
now multiply this by the height
78.5 x 3 = 235.5cm³
Step-by-step explanation:
x^2+2x+7y=15
7y=15-x^2-2x
y=15/7-1/7x^2-2/7x , x ∈ all real numbers
The formula for the future value of the account is
A = P(1 + r/n)^(nt)
where you have
A = 19909.20
P = 8975
r = 0.038
t = 21
The resulting equation is not one that can be solved by algebraic means, but we can use a graphing calculator to find n. This graph shows us n = 12, so
the interest compounds monthly.
