Hope this helps you..!!!
Answer:
r=4
Step-by-step explanation:
Area of a circle is
A = pi* r^2
We know the area and 3.14 = pi
50.24 = 3.14 * r^2
Divide each side by 3.14
50.24/3.14 =3.14 /3.14 *r^2
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
The mean is 13 and the median is 8. to sum them up i would say that they are both pretty close so the answer is c
Ok so compound interst formula is

where
F=future amount
A=present amount
c=percent interest in decimal form
n=number of times compoounded per year
t=times in years
A= present amount=100
c=2%=0.02
n=1 since once per year
t=t
so
F=100(1+(0.02)/1)^(1t)
F=100(1+0.02)^t
F=100(1.02)^t
x=1.02
The question doesn't make sense.
az = 8, the z should be a #
an = -3an-1, is this supposed to be
?
What's the z?
