ANSWER IS LAST CHOICE 256/81
You can take the reciprocal of the fraction and drop the negative sign in the exponent. Then:
(-4/3)^4 = (-4)^4 / 3^4 = 256/81
Answer:
The radius is 5 in
Step-by-step explanation:
The area of a circle is given by the formula
A = pi *r^2
We know the area = 78.5 in^2 (volume would be in^3 area is in^2)
78.5 = 3.14*r^2
Divide each side by 3.14
78.5/3.14 = 3.14/3.14*r^2
25 = r^2
Take the square root of each side
sqrt(25) sqrt(r^2)
5 =r
I would say: as the hours spent studying per week increased, the grade point averages increased as well, so all of it is just increasing. I say this because it begins at 0, or almost nothing and works its way up. Hope this is helpful.
