The distance traveled by the ray will be 26 inches. Then the correct option is B.

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

In a science experiment, a student concluded that a ray has to travel a distance from one corner at the top of the rectangular prism to the opposite side where the surface touching the floor is intersected.

If the length, width, and height of the prism are given as 24 inches and 8 inches, 6 inches respectively.

Then the distance traveled by the ray will be

We know the formula

D² = L² + W² + H²

We have

L = 24 in

W = 6 in

H = 8 in

Then the distance will be

D² = 24² + 6² + 8²

D² = 576 + 36 + 64

D² = 676

D = 26 in

Thus, the correct option is B.

More about the coordinate geometry link is given below.

If n^-2 = 1/16, then n could be which of the following?
Zepler [3.9K]

Answer:

The correct choice is

\boxed{n=4}

Step-by-step explanation:

The given equation is

n^{-2}=\frac{1}{16}

We rewrite the left hand side of the equation as a power(a number to a given exponent.

n^{-2}=\frac{1}{4^2}

Recall that;

\frac{1}{a^m}=a^{-m}

We apply this property to obtain;

n^{-2}=4^{-2}

Since the exponents are the same, the bases are also the same.

Therefore n=4

A cylinder has a height of 6 meters and a radius of 3 meters. What is its volume? Use ​ ≈ 3.14 and round your answer to the near
bija089 [108]

Answer:

169.56 m³

Step-by-step explanation:

» <u>Concepts</u>

The volume of a cylinder is how much space there is inside the cylinder. The formula to find the volume is πr²h, where r = radius and h = height. Once you get the volume, you have to add <unit>³.

» <u>Application</u>

We are given the radius as three meters and the height as six meters; we also have to use π as 3.14. Now, we just have to plug in these values into the aforementioned formula.

» <u>Solution</u>

  • <u></u>3.14*3^3*6
  • 3.14*9*6
  • 28.26*6
  • 169.56
