Need #47 and #48 asap!!<br> 20 pts!!
sergey [27]

Answer:

47-Step-by-step explanation:

X=121 because they are vertical angles

48- first divide 96 by 6 together the surface area of each side which is equal 16 then to find the length and the width find the square root of 16 which is 4 because it is a cube the length/width/height are all equal to four. So do 4 x 4 x 4 to find the volume of one cube. Which is equal to 64 then multiple by 8 to get the total volume 512cm^3

What is the equation of the circle with center (0, 1) and a radius of 10?
victus00 [196]

<u>Answer:  </u>

The equation of the circle with center (0, 1) and a radius of 10 is \bold{x^{2} + y^{2} - 2y-99 = 0}

<u>Solution: </u>

Equation of circle whose center (h, k) and radius r is given as,

(x-h)^{2} + (y-k)^{2} = r^{2} ---- eqn 1

From question, given that the circle has radius 10 and center (0, 1). We have to find the equation of the circle.

Hence we get, h = 0 ; k = 1; r = 10

By using eqn 1, the equation of circle whose center (0, 1) and radius 10 is given as

(x-0)^{2} + (y - 1)^{2} = 10^{2}

On Simplifying we get

x^{2} + (y-1)^{2} = 10^{2}

Expand (y-1)^{2} using the formula (a-b)^{2} = a^{2} - 2ab + b^{2}

x^{2} + y^{2} - 2y + 1 = 10^{2}

x^{2} + y^{2} - 2y + 1 = 100

x^{2} + y^{2} - 2y + 1-100 = 0

x^{2} + y^{2}- 2y- 99 = 0

Hence equation of the circle with center (0, 1) and a radius of 10 is  \bold{x^{2}+y^{2}-2 y-99=0}

Please answer this! (from khan academy 6th grade math)
Sladkaya [172]

Answer:

(-5, -7) and the x-axis

Step-by-step explanation:

when looking for a point that is 7 points away, we are looking for a difference of 7 in either the x-value or the y-value.

[remember: a point is written as (x, y) ]

We know that the x-value is -7, meaning that it is 7 units under the x-axis (meaning that it is 7 units away)

We know that our point, (2 , -7) has the same y-value as (-5, -7), so we are looking for a change in x. The difference (which is the change) between:

-5 and 2 is 7

(2 - (-5) = 2 + 5 = 7)

so, both the x-axis and the point (-5, -7) are 7 units away from (2, -7)

(the other point (-7, 7) is not near (2 , -7) at all--they have a larger difference on both the y-values, the x-values, and the length of if you made a diagonal line)

(I've attached an image to help you visualize what we're doing)

hope this helps!!
