Exponent is the expression in where you convert product factor expression into a shorter expression. So really you use it to make the question simpler and shorter(easier to understand).

Answer:

Step-by-step explanation:

Using exponents is an abbreviated form of repeated multiplication. That is, exponents are used to write a multiplication composed of several equal numbers in a more simplified way.

This is called power, and it is formed by the base, which is the number that is multiplying several times, and by the exponent, which is the number of times the base is multiplied.

For example: 5x5x5x5x5x5x5. You can see that the number 5 is multiplied many times, that makes it longer. This would be the basis. The number 5 is multiplied 7 times (7 being then the exponent), therefore you can express this multiplication as:

$5^{7}$

Andre owns a computer backup service. He charges his customers $2.50 for each backup CD. His expenses include $875 for the CD re

alukav5142 [94]

Answer:

$p =2.15n - 875$

Step-by-step explanation:

Given

$CD_s= n$

$Charges = 2.50$ per CD

<u>Expenses</u>

$E_1 = 875$

$E_2 = 0.35$ per CD

Required

The profit (p)

First, calculate the total income on n CDs

$Total = Charges * n$

$Total = 2.50 * n$

$Total = 2.50n$

Next, the expenses on n CDs

$Expenses = E_1 + E_2 * n$

$Expenses = 875 + 0.35 * n$

$Expenses = 875 + 0.35n$

The profit (p) is:

$p = Total - Expenses$

$p =2.50n - (875 + 0.35n)$

Open bracket

$p =2.50n - 875 - 0.35n$

Collect like terms

$p =2.50n - 0.35n - 875$

$p =2.15n - 875$

What is the answer and why is it the answer

Afina-wow [57]

The answer is the third answer because it is the only option where the number 45 is multiplied by something bigger than 1. If something is multiplied by something smaller than one then it will be smaller than the number multiplied.

Aka: 45x0.8 is 36, because 0.8 is smaller than one

Write in 0 and 0 at the top: this indicates that if there are zero pennies, the height of the tower is 0. This is the point (0,0). Another point is (4, 28): a tower of 28 pennies is 4 cm tall.

Find the slope of the line connecting (0,0) and (4,28).
4cm - 0 cm
m = ----------------- = (1/7) (cm/penny)
28 - 0

The equation we need, relating # of pennies to height of tower, is

t = (1/7) (cm/penny)x, where x is the # of pennies.

Thus, if x = 1, then t=1/7 cm

And, if x =15, then t = 15/7 cm

And so on.

Lunna [17]

f(x)=lnx

y=f(x)

dy/dx= 1/x

tangent at (x,y) has slope 1/x

eqn of tangent is y = mx + c

since the tangent passes through origin, c=0

substitute y = lnx and m= 1/x to above eqn

lnx = 1

x=e

y=lne=1
