Answer: The answer is 14 units I believe.
Answer: 3x^2 - 10x + 8 = (x -2)(3x-4)
We are asked to simplify the given mathematical expression a5*3b9*6a. To do this, we need to follow the law of exponent that if it is same variable being multiplied we can add the power. In this problem, variable "a" existed twice so we can add powers of a5 to 6a such as:
6a(5+1) *3b9
6a6*3b9 , then multiply constants which are 6 and 3
18a6b9
The answer is 18(a^6)(b^9).
The formula for surface area of a sphere is A=4*PI*r^2
Using that formula and the known surface are we can find the radius. We can then use that to find the volume.
500 = 4*PI*r^2
Divide both sides by 4:
500/4 = PI *r^2
125 = PI *r^2
Divide both sides by PI
125/PI = r^2
39.79 = r^2
r = SQRT(39.79)
r = 6.3 cm
Now we can find volume using V=4/3*PI*r^3
V = 4/3 *PI *6.3^3
V= 1051.3
The answer is C
