Write the standard equation for the circle center (-6,8) that passes through (0,0)
Reil [10]

Answer:

D

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 6, - 8), thus

(x + 6)² + (y + 8)² = r²

The radius is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)

r = \sqrt{(0+6)^2+(0+8)^2} = \sqrt{36+64} = \sqrt{100} = 10

Hence

(x + 6)² + (y + 8)² = 100 → D

Help please now i cant figure it out
12345 [234]

Answer:

a. \frac{-11}{24}

b. \frac{-3}{2} \\

c. \frac{31}{7}

d.  \frac{11}{16}

11, 3, 31, 11 = code

Step-by-step explanation:

a. \frac{-1}{6}\\ * 2\frac{3}{4} =

2\frac{3}{4} = \frac{4*2+3 }{4}=  \frac{11}{4}

\frac{-1}{6}\\ * \frac{11}{4} = \frac{-1*11}{6*4} = \frac{-11}{24}

b.  \frac{3}{16} / \frac{-1}{8} =

\frac{3}{16} * \frac{8}{-1} = \frac{3*8}{16*-1} \\ = \frac{24}{-16} = \frac{-3}{2} \\

c. \frac{-31}{56} * \frac{-8}{1} = \frac{31}{7} (you can reduce 8 & 56 by dividing by 8: 56/8=7 & -8/8= -1)

d. 1 \frac{7}{8} / 2\frac{8}{11} =

1 \frac{7}{8} = \frac{8*1+7}{8} = \frac{15}{8}

2\frac{8}{11} = \frac{11*2+8}{11} = \frac{30}{11}

\frac{15}{8} * \frac{11}{30} = \frac{11}{16} (you can reduce 15 & 30 by dividing by 15: 15/15=1 & 30/15 = 2)
