Answer:

Step-by-step explanation:

The given equation is in slope-intercept form:

y = mx + b

where the slope is m = -3 and the y-intercept is b = +2.

So, the graph will have a slope of ...

"rise"/"run" = -3 = -3/1

and will cross the y-axis at y=2.

Graphs A and B cross the y-axis in the right place, but only Graph B has a negative "rise" a x increases.

For the right triangle shown, the lengths of two sides are given. Find the third side. Leave your answer in simplified, radical

Answer: $c=4\sqrt{2}$

Step-by-step explanation:

For this exercise you need to apply the Pythagorean Theorem. This is:

$h^2=l^2+m^2$

Where "h" is the hypotenuse of the Right triangle and "l" and "m" are the legs.

In this case, you can identify that:

$h=c\\\\l=a=4\\\\m=b=4$

Knowing these values, you can substitute them into $h^2=l^2+m^2$ :

$c^2=4^2+4^2$

Now you must solve for "c":

$c=\sqrt{4^2+4^2}$

Evaluating, you get:

$c=\sqrt{16+16}\\\\c=\sqrt{32}$

To simplify the result:

- Descompose 32 into its prime factors:

$32=2*2*2*2*2=2^5$

- By the Product of powers property, you know that:

$2^5=2^4*2$

- Make the substitution:

$c=\sqrt{2^4*2}$

- Finally, knowing that $\sqrt[n]{a^n}=a$ , you get:

$c=2^2\sqrt{2}\\\\c=4\sqrt{2}$

Part C:

y = total cost

M = minutes

You can talk on the phone only 100 minutes per month

Company A:

y = 0.04M + 5

y = 0.04(100) + 5

y = 4 + 5

y = 9 $9 per month

Company B:

y = 0.10M + 2

y = 0.10(100) + 2

y = 10 + 2

y = 12 $12 per month

Company A offers the best deal because at Company A you have to pay $9 for 100 minutes per month, and at Company B you have to pay $12 for 100 minutes per month, so you have to pay $3 less.

Part D:

1.) With a budget of $30, Company A would allow me to talk longer on the phone. I know this because for Company A, you pay $3 less per month for the same amount of minutes as Company B. This means that I will save more money with Company A, and I can buy more minutes. (something like this)

How do you round an irrational number to the nearest hundredth

MariettaO [177]

To round to the nearest cent, nearest penny, or nearest hundredth, you will need to locate the hundredths place. Then look at the digit to the right. If it is 5 or above, the number in the hundredths place will be increased by 1 and all the rest of the numbers after it are dropped. If the number is 4 or below, you leave the digit in the hundredths place alone and drop all the rest of the numbers after.

<span>Just remember, if the problem asks you to round to the nearest hundredth, make the end result look like money, meaning only two digits after the decimal point!</span>
