Give the equation of the circle centered at the origin and passing through the point (0,-8)
Norma-Jean [14]

Answer:

The answer to your question is x ² + y² = 64

Step-by-step explanation:

Process

1.- Find the length of the radius

C (0, 0)

P (0, -8)

d = \sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}  }

d = \sqrt{(0- 0)^{2}+ (-8 - 0)^{2}  }

d = \sqrt{64}

d = 8

2.- Find the equation of the circle

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

h = 0   and k = 0

    (x - 0)^{2} + (y - 0)^{2} = 8^{2}

            x² + y² = 64

A polynomial is factored using algebra tiles
dezoksy [38]

Answer:

A) x^2-2x-8

Step-by-step explanation:

The polynomial factored is equal to the area of the algebra tiles. This means the quadratic is

x^2 + x+ x -x -x -x -x-1-1-1-1-1-1-1-1\\x^2-2x-8

After writing out each tile as a term, combine like terms to simplify. This ia the quadratic.

x^2-2x-8

Please help me. i will mark you as most brilliance and give you 5 stars! Please be specific when answering. thank you! :)
serg [7]

Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

URGENT!: Which best explains why these two figures are similar or not similar?
-BARSIC- [3]

Answer:

These two figures are similar because \frac{5}{3} equals \frac{15}{9}.

Step-by-step explanation:

The figures will be similar if their ratios of the two sides are equal. So we need to check the ratios of the figures to see if they are similar or not.

For the smaller figure the ratio is \frac{5}{3}, and for the bigger figure the ratio is \frac{15}{9}. which upon simplification reduces to  \frac{5}{3}.

So we see that the ratios are equal. Thus the figures are similar.
