The volume of a cubic cardboard box is 125/8 ft3.

lina2011 [118]

Answer:

The answer is

Step-by-step explanation:

Since the cardboard box is a cube all it's sides are equal

Volume(V) of a cube = l³

where l is the length of one side

From the question

$V = \frac{125}{8} \: {ft}^{3}$

The length of each side of the cardboard box is

${l}^{3} = \frac{125}{8} \\ \sqrt[3]{ {l}^{3} } = \sqrt[3]{ \frac{125}{8} } \\ l = \frac{5}{2}$

We have the final answer as

$\frac{5}{2} \: \: \: feet \\$

Hope this helps you

Cot^2x-csc^2x=-1 for all values of x true or falsse

Leno4ka [110]

Our basis for this equality is the pythagorean theorems of trigonometry. There are three equations for the pythagorean theorems. These are:

sin²x + cos²x =1
1 + tan²x = sec² x
1 + cot² x = csc² x

These are all derived from circle geometry on the cartesian plane. Now, the useful trigonometric property to be used is the third one. Rearranging this, we come up with

cot²x - csc²x = -1

This coincided with the given equation. Therefore, this is true. This is because it is already established from the pythagorean theorems.

Express M in terms of B and n: B = 3Mn 2

Molodets [167]

We are given the expression B=3Mn/2 and told to express M in terms of B and n. This means that we should apply mathematical operations on both sides of the equation so we "isolate " M on one side of the equality sign. We begin with the given equation

$B=\frac{3\cdot M\cdot n}{2}$

First, we multiply both sides by 2, so we get

$2\cdot B=3\cdot M\cdot n$

Next, we divide by 3 on both sides, so we get

$\frac{2\cdot B}{3}=M\cdot n$

Finally, we divide both sides by n, so we get

$\frac{2\cdot B}{3\cdot n}=M$

In this case, we have succesfully expressed M in terms of B and n
