The <em><u>correct answer</u></em> is:

C. (1, 1/2) (2, 1/4) (3, 1/8) (4, 1/16)

Explanation:

In order to be an exponential function, the y-coordinates of each point should be multiplied by a constant to get the next y-coordinate.  For C, we multiply by 1/2:

1/2(1/2) = 1/4; 1/4(1/2) = 1/8; 1/8(1/2) = 1/16

This means it is an exponential function.

When you divide a whole number by a decimal less than 1, the quotient is greater than the whole number. why?
Viktor [21]
Well if you get back to the definition of a division, diving X by Y is finding out how many Ys you can have in a X.

It is clear that you will have more than X times Y if Y is less than 1 since dividing X by 1 is exactly X.

If you think of 10 and 1, you can divide 10 in exactly 10 portions of 1.
But you can divide it into 100 portions of 0,1.
And 100 is bigger than 10 of course.
Hope this helps.

Which expression uses the greatest common factor and the distributive property to rewrite the sum 7 + 75
Lady_Fox [76]

Answer:

75 + 45 = 15(3 + 5)

Step-by-step explanation:

Given

75 + 45 <em>-- Corrected</em>

Required

Use the GCF to write it as a distributive property

First, we find the GCF of 75 and 45

45 = 3 * 3 * 5

75 = 3 * 5 * 5

The common factor is:

GCF = 3 * 5

GCF = 15

So, 75 + 45 becomes

75 + 45 = 15 * 3 + 15 * 5

Factorize

75 + 45 = 15(3 + 5)

<em>Hence, the sum has been rewritten as </em>15(3 + 5)<em></em>

Hi! If you have time, I am stuck on this problem. I don't get it. You need to find the net pay and I was wrong. Please help. No
ElenaW [278]

Answer:

Your pay before taxes are $292.50 (gross earnings)

So your total tax is $31.55 (Total deductions)

After the tax is deducted the pay is $260.95 (net pay)

The rest of the answers to the chart are below and bolded

Step-by-step explanation:

Okay simple explanation

you need to find total and the tax for each one by multiply by it’s percent

THe total you cna get of course form multiply 30 hours by 2.75 per hour so you’d get 292.50

Now to find the tax just multiply 292.50 by the percents given and make sure to move those decimal Places

292.50*0.1=29.25 (federal tax / 10%)

292.50*0.062=1.86 (ss tax / 6.2%)

292.50*0.0145=0.435 {round that to nearest penny 0.44} (Medical care/ 1.45%)
