SSSSS [86.1K]

Answer:

Center (4, -13)

Radius = 17

Step-by-step explanation:

Circle equation: $( x - h )^2 + ( y - k )^2 = r^2$

(h, k) is the center of the circle and the r is the radius.

$(x-4)^{2} +(y+13)^{2} = 289$

h = 4, k = -13, r = 17

Part B

stira [4]

<h3>Given:</h3>

Radius of 50 point region= 3 in
Width of other regions= 4 in

The area of the target which earns 30 points on a throw.

<h3>Solution:</h3>

$\huge\boxed{Formula: a= \pi{r}^{2}}$

$4+3$

$=7$

Let's solve

We have to find the answer in terms of π so, we'll just have to multiply the radius by itself.

$a={7}^{2}$

$\large\boxed{a= 49 \pi\: {in}^{2}}$

Hence, the area of the target which earns 30 points on a throw is 49π square inches.

Adam, Brian, and Casey are all brothers. Brian is three years less than twice Casey’s age. Adam is 9 years older than Casey. The

blagie [28]

Let Casey's age be x

Brian's age will be -3 from 2 times x ( Casey's age ) so it will be 2x-3

Adam's age will be Casey's age (x) + 9 which is x+9

NOW the sum of all these ages is 46 so..

Casey's age + Brian's age + Adam's age = 46

x + 2x-3 + x+9 = 46

2x + x + x + 9 -3 = 46

4x + (9 - 3) = 46

4x - 6 = 46

now transfer the numbers on the left one by one to the other side( right )

4x = 46 - 6 ( always remember the sign of the number becomes the opposite when we transfer them to other side)

4x = 40

x = 40 / 4

x = 10

so x = Casey's age = 10

2x - 3 = Brian's age = 2 * 10 - 3

= 20 - 3 = 17

x + 9 = Adam's age = 10 + 9 = 19
