Ok, 1 bionimial theorem coming right up
for a binomial expansion of (a+b)^n
the kth term is
means
n is 5
4th term
4-1=3
and a=2x
b=5
so
(10)(4x^2)(125)
5000x^2 is the 4th term
-11 and -1. they add up to -12. they are multiplied to 11
Answer:
128 + 96√3 or 294.28 unit^3 to the nearest hundredth.
Step-by-step explanation:
The surface area of one of the pyramids = area of the square base + area of the 4 equilateral triangles
= 8^2 + 4 * 1/2 * 8 * 4√3
= 64 + 64√3.
So the area of the new solid = 2(64 + 64√3) - area of 2 triangles
= 2(64 + 64√3) - 32√3
= 128 + 128√3 - 32√3
= 128 + 96√3.

There is a formula for this:
Total Time = (worker1 * worker2) / (worker1 + worker2)
(3 * 8) / (3 + 8)
24 / 11 =
2.1818181818 hours
