Question

PLEASEEEE HELPPPPP MEEEEEEE. I think it is 43

48. In the circle, mBC = 86°. The diagram is not drawn to scale.
What is m∡BCP? (1 point)
43°
86°
90°
172°

Answer 1

Can you help?

Answer 2

Yes, you are correct

Answer 3

OMG THANKS. I have another.

Answer 4

53. What is the equation of the circle with center (–4, –3) that passes through the point (6, 2)? (1 point)
(x – 4)2 + (y – 3)2 = 25
(x – 4)2 + (y – 3)2 = 125
(x – (–4))2 + (y – (–3))2 = 25
(x – (–4))2 + (y – (–3))2 = 125

Answer 5

what is your choice?

Answer 6

Im between b and d

Answer 7

go ahead, so far so good. Now, make decision

Answer 8

Okay. b?

Answer 9

hahahaa.... Are you sure?

Answer 10

no, thats why im asking for help

Answer 11

don't forget center is (-4,-3)

Answer 12

not (4,3)

Answer 13

ohh okay so d

Answer 14

Again, sure??

Answer 15

trust yourself

Answer 16

uhm no. I was thinking b or d because of the 125 at the end. Im really bad at this. Can you help me?

Answer 17

(x-h) ^2 + (y-k)^2 = r^2
h = (-4) ; k = (-3)
so \(\Large (x- (-4)^2 ...\) is the correct one. So??

Answer 18

andd im confused. would it be a then?

Answer 19

d is correct one
a has the left hand side is ok, but the right hand side =25 makes it wrong

Answer 20

oh. I guess i shouldnt second guess myself. Can you help me with another?

Answer 21

just post, If I can, I will.

Answer 22

52. What is the standard equation of the circle in the graph?
(x + 3)2 + (y – 2)2 = 9
(x – 3)2 + (y + 2)2 = 9
(x – 3)2 + (y + 2)2 = 3
(x + 3)2 + (y – 2)2 = 3

Answer 23

don't you know how to do or you just get stuck at some where? Tell me what do you have so far

Answer 24

I dont know this one at all. I failed the circle part of all my test this semester

Answer 25

Hint: find the coordinate of center . I mean (h,k)

Answer 26

-2,2?

Answer 27

(-3,2) check whether I am right or not

Answer 28

Oh yes yourr right. I didnt realize it was by 2s

Answer 29

confirm (h, k) =(-3,2); separate them , we have h =-3, k =2 right?
I cheat a little bit on the radius. hihihi
from the center, you count the horizontal direction, what is the radius?

Answer 30

is the radius 2?

Answer 31

it is 3 units , right? so r =3
now you have (h,k) you have radius =3 just plug all into the formula

Answer 32

ah 3?

Answer 33

so?? the answer is??? Work on it?? don't wait for me. I won't do your homework.

Answer 34

is it c?

Answer 35

hey, you guess??? NO!!
you have radius =3 , if it is c, how r^2 =3 still?

Answer 36

I really dont understand this. Can you show me how to do it for next time? Im not asking you do give me the answer right off. Explain

Answer 37

next time? not now?

Answer 38

After looking at it i think its d? Can you review that and check it?

Answer 39

ok, I explain it now, h = -3 , k =2 radius r =3 . The equation of the circle is
\[(x-\color{red}{h})^2 + (y-\color{blue}{k})^2=r^2\\(x-\color{red}{(-3)})^2 + (y-\color{blue}{2})^2=3^2\\(x\color{red}{+3})^2 + (y-\color{blue}{2})^2=9\]

Answer 40

Oh so its a
