Answer:

<u>B. 1/2 and 1.</u>

Step-by-step explanation:

The coefficient of a variable is the number that the variable is being multiplied for. In this example. We can see that x² is being multiplied by 1/2, therefore <u>1/2 is one of the coefficients</u>.

In the case of x, it doesn't have a number before it, it means that it's being multiplied by 1. Hence, our <u>second coefficient is 1</u>.

A sphere has a volume of 457.3 in^3. What is the radius of the sphere?
Ne4ueva [31]

Answer:

\large\boxed{R\approx4.78\ in}

Step-by-step explanation:

The formula of a volume of a sphere:

V=\dfrac{4}{3}\pi R^3

R - radius

We have the volume V = 457.3 in³. Substitute:

\dfrac{4}{3}\pi R^3=457.3\qquad\text{multiply both sides by 3}\\\\4\pi R^3=1371.9\qquad\text{divide both sides by 4}\\\\\pi R^3=342.975\qquad\text{divide both sides by}\ \pi\\\\R^3=\dfrac{342.975}{\pi}\qquad/\pi\approx3.14/\\\\R^3\approx\dfrac{342.975}{3.14}\\\\R^3\approx109.2277\to R\approx\sqrt{109.2277}\\\\R\approx4.78\ in
