Explanation:

f(n) + g(n) = (-2n^3 + 3n^2) + (-2n - 4)
f(n) + g(n) = -2n^3 + 3n^2 - 2n - 4

How will the volume of the pyramid change if each side is multiplied by a factor of 5?

o-na [289]

The volume of the pyramid is changed by a factor of 125

<u>Solution:</u>

Given that, each side of a pyramid is multiplied by a factor of 5.

We have to find how will the volume of the pyramid changes?

Now, we know that, volume of a pyramid $=\frac{\text {length} \times \text { breadth } \times \text {height}}{3}$

Now, each dimension is multiplied by factor of 5.

Then, volume of new pyramid $=\frac{(5 \times l e n g t h) \times(5 \times \text { breadth) } \times(5 \times \text { height })}{3}$

$=5 \times 5 \times 5 \times \frac{\text { length } \times \text {breadth\timesheight}}{3}$

Volume of new pyramid = 125 $\times$ volume of old pyramid.

Hence, the volume of the pyramid is changed by a factor of 125.

Answer:

Angle 5 = 35 degrees

Step-by-step explanation:

A straight line is equal to 180 degrees, meaning 1 + 2 + 5 = 180 degrees because they make up a straight line.

Angle 2 = 55 degrees

Angle 1 = 90 degrees (because it is a right angle)

Angle 5 = ?

Set up an equation:

90 + 55 + angle 5 = 180

145 + angle 5 = 180

Angle 5 = 35

Can someone explain how u can write a percent in simplest form?

mash [69]

Answer:

The answer is 1 1/4 or a.

Step-by-step explanation:

Basicallly percents are based of 100% so there is a 100% which would be a whole then there is only 25% and if you take 4 quarters and each quarter is 25 cents and there is 4 quarters in a whole that would be 1/4. You add the 1 whole and the 1/4 to get 1 1/4.

Hope this helps, tried to explain it in the best way I can.

Which beat explains what determines whether a number is irrational?

lisov135 [29]

Answer:

The correct answer is Choice D. An irrational number is a number that can be written as a decimal but never terminates or repeats.

A good example of an irrational number is the number pi. We know that it begins as 3.14. However, that is only the beginning. It goes on forever without repeating or terminating.
