1. Need distance formula to find how long it is then cut it in half to find the radius....d= 10.....r= 5

Need midpoint formula to find the center....midpoint= (-1, -1)

(h,k) in the equation of a circle is the center, "r" is the radius. When you plug in the center, you have to put the opposite signs...so......

equation of a Circle = (x - h)^2 + (y - k)^2 = r^2 = (x + 1)^2 + (y + 1)^2= 25

2. A= pi(r^2)

200.96= 3.14(r^2)

64 = r^2

r = 8

Then to find the circumference, C= 2(pi)(r) = 2 (3.14) (8) = 50.24

For 3 and 4, is there a diagram?

A quilt design uses parallelogram-shaped pieces that have a base measure of 4 inches and a height of 6 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?

1.225 in.

2.360 in.

3.(450 in.)

4.900 in.

<span> 15*4*6 = 360 sorry but I only have the answers for number 1 and 2

</span>

The value of this problem would be 126. The degrees of the triangle is 180 so add the numbers 45 + 9 which equals 54. Then, you need to subtract 180 from 54 and that's how you find the value.

**Answer:**

C 1/2

**Step-by-step explanation:**

There are 4 suits, 2 suits are red (hearts and diamonds) while 2 are black (clubs and spades)

Since 13 cards are in each suit, 26 cards are red ( 2 * 13)

There are 52 total cards

P (red) = red cards/ total cards

= 26 / 52

= 1/2

**Answer: **

Assuming the questions wants another form of 6x²+13x+5:

(2x+1)(3x+5) would work.

Step-by-step explanation:

Multiply (2x+1)(3x+5) and you'll get 6x^2+13x+5

A = (9,-8) B = (-6,7)

P is (2/3) the line of the line segment from A to B

So, AP = (2/3) AB and BP = (1/3) AB

OR we will divide the length of AB with the ratio 2 : 1 from A

∴ m = 2 , n = 1

∴

** **∴

** **The coordinates of point P is ( -1 , 2 )

The correct answer is option three
