<span>I am guessing Both Table A and Table B represent functions.

I say this because you can plot all of those things on a graph, if you couldn't they wouldn't be functions.

What is the approximate distance between the points (-6, 8) and (4, 13)?

ddd [48]

Answer:

5√5

Step-by-step explanation:

To find the distance you can use the distance formula.

√(13 - 8)^2 + (4 + 6)^2

√25 + 100

√125

The phone company offers Rachel 12c per minute for her long distance calls. A discount company called Rachel and offered her lon

kupik [55]

Step-by-step explanation:

x = number of minutes

the cost function (in c) of the phone company is

cp(x) = 12x

and the cost function of the discount company is

cd(x) = x/2 + 4600 (R46)

we now need to calculate for what x this becomes the same cost :

12x = x/2 + 4600

24x = x + 9200

23x = 9200

x = 400 minutes

she would have to talk for at least 400 minutes long distance per month to make it an even or then better deal.

with 400 minutes being the break-even point.

so, to make it a better deal (not just equal), she has to talk for at least 401 minutes per month.

Write the equation of the circle with center (3,2) and with (9,3) being a point on the circle

miss Akunina [59]

Answer:

$(x-3)^2 + (y-2)^2 = 37$

Step-by-step explanation:

To write the equation of a circle, use the formula $(x-h)^2+(y-k)^2 = r^2$ where the center of the circle is (h, k).

This means the equation is $(x-3)^2 + (y-2)^2 = r^2$ .

Find the radius r by finding the distance between (3,2) and (9,3) using the distance formula.

$d = \sqrt{(9-3)^2 + (3-2)^2} =\sqrt{6^2 + 1^2} =\sqrt{36+1} =\sqrt{37}$

Since the radius is √37 and therefore $r^2 = 37$ .

The equation is $(x-3)^2 + (y-2)^2 = 37$ .
