Find the radius of circle if AB = 24 and OC = 5
Likurg_2 [28]

Answer:

13

Step-by-step explanation:

Since OCB forms a right triangle, you can find the length of side OB and therefore the radius by simply using the pythagorean theorem. The first step is to note that, since AB=24 and OC bisects that, that both CB and AC have length 12. Therefore, the radius is BO=\sqrt{12^2+5^2}=13. Hope this helps!

30 POINTS!!! PLEASE HELP ME
Ludmilka [50]

Remark

All you need is 2 points to get the line of the equation. One is itself (B and B') is the same in both triangles. Now we need to find one more point. Since this is a reflection, the midpoint between C and C' is the second point. That choice of C and C' is completely arbitrary.

Step One

y intercept of the line. That point is B which is (0,1)

Step Two

Find the midpoint between C and C'

C is (-4,-2) and C' is ( 0 , - 4) The midpoint is

C" = (x2 + x1)/2 , (y2 + y1)/2

C" = (-4 + 0 )/2 , (-2 + - 4) / 2

C" = (-4)/2 , - 6/2

C" = (-2, - 3) C" is the midpoint between C and C'

Step 3

Find the equation of the line.

y = ax + b We are trying to find A

y = ax + 1

-3 = a(-2) + 1

-3 - 1 = a(-2)

- 4 = a(-2) Divide by -2

-4/-2 = a

a = 2

The slope of the line is 2

Answer

y = 2x + 1

Grandma Gertrude gave 131313 pieces of jewelry and Grandma Fien gave yyy pieces of jewelry to the Carlson sisters to divide even
alex41 [277]

Answer: (13 + y) / 5

Step-by-step explanation:

Since Grandma Gertrude gave 13 pieces of jewelry and Grandma Fien gave y pieces of jewelry to the Carlson sisters, the total jewellery given to the sisters will be:

= 13 + y

Since there are 5 Carlson sisters, the number of pieces of jewelry that each sister receive will be:

= Total jewelries / Number of sisters

= (13 + y) / 5
