Answer:

200 5/8

Step-by-step explanation:

Since you need to find the area, you multiply 6x15 1/2 and add it to 10 1/4x10 1/2.

Factor 64 – x15. (4 – x3)(16 + 4x3 + x3) (4 – x3)(16 + 4x3 + x6) (4 – x5)(16 + 4x5 + x5) (4 – x5)(16 + 4x5 + x10)
Katen [24]

Answer:

(4 - x^{5} )(16 + 4x^{5} + x^{10} )

Step-by-step explanation:

64 - x^{15} ← is a difference of cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²), thus

64 - x^{15}

= 4³ - (x^{5} )³

= (4 - x^{5} )(4² + 4x^{5} + (x^{5} )² )

= (4 - x^{5} )(16 + 4x^{5} + x^{10})

Which is the best approximation of the volume of a cone with the same base and height as the cylinder?
Sever21 [200]
If the volume of a cylinder is x, then the volume of a cone with same height and diameter is x/3

so

if the cone is 72ft³ then the cone with same base and height is 72/3ft³=24ft³


answer is A

I'm guessing you're given the function y(x)=2-x^3, and you're asked to find the inverse function y^{-1}(x). To do this, swap x and y, then solve for y:

x=2-y^3\implies y^3=2-x\implies y=(2-x)^{1/3}=\sqrt[3]{2-x}

so that the inverse function is

y^{-1}(x)=\sqrt[3]{2-x}

Just to verify:

y(y^{-1}(x))=y(\sqrt[3]{2-x})=2-(\sqrt[3]{2-x})^3=2-(2-x)=x

y^{-1}(y(x))=y^{-1}(2-x^3)=\sqrt[3]{2-(2-x^3)}=\sqrt[3]{x^3}=x

But in case you're actually only interested in computing the square root, first we note that \sqrt x (the real-valued square root) is only defined as long as x\ge0. So \sqrt{-x^3} is defined as long as -x^3\ge0, or x^3\le0, or equivalently x\le0. Under this condition, we could write

\sqrt{-x^3}=\sqrt{-x\times x^2}=\sqrt{-x}\sqrt{x^2}

We can simplify this further, but we have to be careful. Suppose x=-1. Then x^2=(-1)^2=1. But we get the same result if x=1, since x^2=1^2=1. There are two possible values of x that given the same value of x^2, so to capture both of them, we take \sqrt{x^2}=|x|, the absolute value of x. Then

\sqrt{-x^3}=|x|\sqrt{-x}

We can't simplify the square root term further than this.
