Answer:
80.
Step-by-step explanation:
x^2y^3 * x^3y^2
= x^(2+3)y^(3+2)
= x^5y^5 and as x^2y^3 = 10 and x^3y^2 = 8 we have:
10 * 8
= 80.
If the radius is 5 ft, the circumference is 10 pi or about 31.4
1000 divided by 31.4 = 31.8
So, it should make a minimum of 32 revolutions to reach 1000 feet.
To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,
f(a + 2) = (3 + a + 2) / (a + 2 - 3)
Simplifying the function generated above,
f(a + 2) = (5 + a) / (a - 1)
First distribute 3 to (x-4). that gives you 3x-12. Now your equation is x-2=3x-12. Now you subtract x from 3x. now you're equation is -2=2x-12. then add 12 to the left. You're final answer is 10.
