Answer:
S(x)=42000 * 1.04^x
Step-by-step explanation:
now = 42000
in 1 year = 42000 *1,04, because 4% increase is to multiply 1,04
in 2 years = 42000 *1,04*1.04 = 42000*1.04^2
in x years = 42000 * 1.04^x
Answer:
The radius is 7 cm
Step-by-step explanation:
We know the area of a circle is given by
A = pi r^2
49 pi = pi r^2
Divide each side by pi
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
The radius is 7 cm
Answer:
B
Step-by-step explanation:
the radii have to be cubed cause a volume is cubed
3^3:5^3
27:125
I hope this helps and sorry if it's wrong
