Which is the equation of a circle whose center is at the origin and that passes through the point (3, 5)?
xxTIMURxx [149]

Answer:

x² + y² = 34

Formula:

  • (x - h)² + (y - k)² = r²                    where (h, k) is the center

<u>Here find the radius using distance formula</u>:                → origin : (0, 0)

  • √(x2-x1)²+(y2-y1)²
  • √(3-0)²+(5-0)²
  • √9+25
  • √34

<u>Thus the equation of circle</u>:

  • (x - 0)² + (y - 0)² = (√34)²
  • (x - 0)² + (y - 0)² = 34
  • x² + y² = 34

Which is an equation of the line that passes through the points (-6,-8) and (4,-4)
natita [175]

Answer:

y=\frac{2}{5}x-6.5

Step-by-step explanation:

\frac{(-8)-(-4)}{(-6)-4} \\ = \frac{-4}{-10} = \frac{2}{5\\}

y=mx+b

-8 = (\frac{2}{5}) (-6) +b

-8 = - \frac{12}{8} +b

b= -6.5

If f(x)=3x+2, find f(f^-1(14))
krek1111 [17]
F(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14)   f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x
