ANSWER QUICKLY PLEASE, WILL MARK BRAINLIEST (50 POINTS) Question: A diameter of a circle has endpoints P(-10,2) and Q(4,6)

a. Find the center of the circle.

b. Find the radius. If your answer is not an integer express it in radical form.

c. Write an equation for the circle.

a. The Center has coordinates (-10)+4)/2 and (-2+6) / 2 = (-3, 2)

b. The radius is the distance of the center from Q:-

= sqrt (4 - -3)^2 + (6-2)^2))

= sqrt 65

c . Equation of a circle is

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = the radius so our circle has the equation:-

(x + 3)^2 + (y - 2)^2 = 65

Hope this helps! :)

Answer:

A. The centre must be the midpoint of PQ

which would be C( (-10+4)/2 , (-2+6)/2 )

= C(-3,2)

B. radius is √( (4+3)^2 + (2-6)^2) = √65

C. equation:

(x+3)^2 + (y-2)^2 = 65

A cube is packed with decorative pebbles. If the cube has a side length of 2 inches, and each pebble weighs on average 0.5 lb per cubic inch, what is the total weight of the pebbles in the cube?

We can solve this problem by first solving for the total volume of the cube. The formula for volume of cube is given as:

V cube = s^3

Where s is the length of one side which is equivalent to 2 inches. Therefore:

V cube = (2 inches)^3

V cube = 8 cubic inch

Assuming that all the pebble fills the cube without any spaces, then the total weight of the pebbles in the cube would simply be:

Total weight = 0.5 lb per cubic inch * 8 cubic inch

Total weight = 4 lb

Therefore, the total weight of the pebbles in the cube is 4 lbs.

a phone company offers a choice of three text messaging plans plan it gives you unlimited text messages for $10 a month. Plan B charges $5 a month and plus $0.05 for each text message you send and plan C has no monthly fee but charges you $0.10 per message. write an equation for the monthly cost of each of the three plans

A.

$10

B.

$5 + 0.05t

(T = per text)

C.

0.10t

That’s what I got from the wording so hope that helped.

Need Help!!! ASAP A probability model includes P(red) = 2/7 and P(blue) = 3/14 which of the following probabilities could complete the model? Select all that apply.

P(green) = 2/7 P(yellow) = 2/7

P(green) = 3/8 P(yellow) = 1/8

P(green) = 1/4 P(yellow) = 1/4

P(green) = 5/21 P(yellow) = 11/21

P(green) = 3/7 P(yellow) = 1/14

Answer:

Step-by-step explanation:

The given probabilities are:

Their sum is

The probabilities that will complete the model should add up to so that the sum of all probabilities is 1.

Answer:

P(green) = 38, P(yellow) = 18

P(green) = 14, P(yellow) = 14

P(green) = 37, P(yellow) = 114
