Question

MEDAL :)

Answer 1

Using the following equation, find the center and radius:

x2 −2x + y2 − 6y = 26

The center is located at (−1, −3), and the radius is 36.

The center is located at (1, 3), and the radius is 36.

The center is located at (−1, − 3), and the radius is 6.

The center is located at (1, 3), and the radius is 6.

Answer 3

@israr000

Answer 4

I woul say C

Answer 5

*Would

Answer 6

Help

Answer 7

you would need to complete the square to be sure

Answer 8

x2 −2x +1 + y2 − 6y +9 = 26 +1 +9 , radius of 6 is looking good

(x-1)=0 and (y-3)=0 do not give us a center at -1,-3

Answer 9

Right so looking at this our only solution would be D

Answer 10

correct

Answer 11

YAY! I have one more similar to this one. Give me a sec

Answer 12

A circle is represented by the equation below:

(x + 8)2 + (y − 3)2 = 100

Which statement is true?

The circle is centered at (−8, 3) and has a radius of 20.

The circle is centered at (8, −3) and has a diameter of 20.

The circle is centered at (8, −3) and has a radius of 20.

The circle is centered at (−8, 3) and has a diameter of 20.

Answer 13

So I would say B idk about u

Answer 14

your issue seems more to do with finding a center on these.

the center will zero out your x and y parts:

x+8=0
y-3=0

Answer 15

Ok, Then we..............

Answer 16

then we choose the one that has the right center

Answer 17

So supposing this, it would mean that D right?

Answer 18

yes

Answer 19

@amistre64 Is it okay to explain something then give the answer? Or do you HAVE to lead them to it?

Answer 20

YAY! OMG UR AN AWSOME TEACHER

Answer 21

you have to lead them to it, and then correct them as needed.

Answer 22

:)

Answer 23

Oh

Answer 24

I have this one too. I hope im not too much of a bother.

Snowy's Snow Cones has a special bubble gum snow cone on sale. The cone is a regular snow cone that has a spherical piece of bubble gum nested at the bottom of the cone. The radius of the snow cone is 3 inches, and the height of the cone is 5 inches. If the diameter of the bubble gum is 1.1 inches, what is the closest approximation of the volume of the cone that can be filled with flavored ice? Use 3.14 for pi.

31.87 cubic inches

36.92 cubic inches

46.40 cubic inches

62.87 cubic inches

Answer 25

I was saying C but my sister says its B

Answer 26

this one has a few steps to it

determine the volume of a truncated cone, and subtract the volume of half a sphere.

Answer 27

My sis did the steps and got the answer B it looks pretty convincing but im not sure

Answer 28

But after considering I and doing the math we came up to A. What do u think @amistre64

Answer 29

The radius of the snow cone is 3 inches,
and the height of the cone is 5 inches.

5h to 6d ratio

If the diameter of the bubble gum is 1.1 inches,

5(1.1)/6 to 6(1.1)/6
.916667 height with a radius of .55

5 * 3^2 pi/3 - .916667*.55^2pi/3 = volume of truncated cone


subtract from that: 1/2 (4pi .55^3/3)


what is the closest approximation of the volume of the cone that can be filled with flavored ice? Use 3.14 for pi.

Answer 30

5 * 3^2 pi/3 - .916667*.55^2pi/3- 1/2 (4pi .55^3/3)

the wolf says C is the better route

Answer 32

Yay i was right :)

Answer 33

So this is the oficial last one :P

Answer 34

Lines CD and DE are tangent to circle A as shown below:

Answer 35

If arc CE is 130°, what is the measure of ∠CDE?

20°

40°

42.5°

50°

Answer 36

So after calculations we got to B what do u think? did we do good.

Answer 37

what were the calcs you used?

Answer 38

Well they used postulates. Idk why but I was going to say it was C bcause its most resonable.

Answer 39

bcause since it is 130 degrees the other 42.5 would be better in then 40

Answer 40

what is the sum of the inside angles of a square (a regular quadralateral)?

Answer 41

is it not 180

Answer 42

trianlge is 180

square is 4*90 = 360

Answer 43

we are given, x + 90+90+130 = 360 in this case

Answer 44

Ohhh

Answer 45

we could also do an average ...

(360-130)-130

Answer 46

So answer would be.

Answer 47

ive given you 2 options to work with ... the math is simple enough. what are the results?

Answer 48

internet likes to conk out ...
