25 points. What is the value of this expression? 1/4^-3
Inga [223]

Answer:

64

Step-by-step explanation:

A negative exponent means we first calculate the exponent, then we take the reciprocal.

The first step is to calculate (\frac{1}{4})^3. This is equal to \frac{1*1*1}{4*4*4}=\frac{1}{64}. Then, we take the reciprocal. The answer is 64.

Answer:

Rate of Change is 1

Step-by-step explanation:

The Average rate of change is the ratio of change in y and the change in x

Hence

Avg Rate of Change  = Change in y / Change in x

The two coordinates are

(-4,0) and (0,4)

Change in x = 0-(-4) = 4

Change in y = 4-0 = 4

Hence

Avg Rate of Change = 4/4

= 1

Answer = 1

5c-6=4-3c<br>2c-6=4<br>2c=10<br>c=5<br>describe the error made in the problem.​
SVETLANKA909090 [29]

Answer:

5(c) - 6 = 4 - 3(c) is wrong

Step-by-step explanation:

The other problems are correct and equal. This one is wrong because when you do the equations you get 19 = -11 which is clearly not equal. You would need to change the equation to make it equal. So it would be:

5(c) - 6 = 4 - -3(c) so now it is 19 = 19.

So you would change 5(c) - 6 = 4 - 3(c)  into 5(c) - 6 = 4 - -3(c)

<em>I hope this helps :)</em>

If your total annual income was $30,694.95, then how much did you earn per month, on average?​
tatuchka [14]

In average, your monthly income is $2,557.91

<h3>How much did you earn per month, on average?​</h3>

We know that in the year you win a total of $30,694.95, and we want to know how much you win per month.

We know that in a year there are 12 months. To get how much you win, in average, in one of these months, you need to take the quotient between the total amount that you earn in one year, and the number of months in a year.

It gives:

N = $30,694.95/12 = $2,557.91

In average, your monthly income is $2,557.91
