Mathematics
1 answer:
Alex787 [66]3 years ago
8 0

Answer:

option (3)

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = x² - 12x + 7

Using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 12x

f(x) = x² + 2(- 6)x + 36 - 36 + 7

      = (x - 6)² - 29

with vertex (h, k ) = (6, - 29 )

Need answers quick. Find the endpoint of the line segment with the given endpoint and midpoint. Endpoint: (−6,−6) Midpoint: (−2,
HACTEHA [7]

Answer: The second endpoint is  (2,6)

Step-by-step explanation:

\frac{-6 +x}{2} = -2  solve for x  

-6 +x = -4

+6        +6

x= 2

\frac{-6+y}{2} = 0  

-6 + y = 0

+6         +6

 y= 6

What is the equation for a circle with center (2, -3) and radius of 6?
torisob [31]
The general formula for a circle is:
x^2 + y^2 = r^2

Since the r^2 = 36, we know the first two options are incorrect 

If the circle's centre is at (2, -3), the numbers being squared should be the negative of the coordinate

So, the final answer is (x-2)^2 + (y+3)^2 = 36
