What is the equation of the circle with center (1, 1) that passes through the point (−3, 4)?
Alex_Xolod [135]

Answer:  (x - 1)² + (y - 1)² = 25

<u>Step-by-step explanation:</u>

The formula for a circle is     (x - h)² + (y - k)² = r²     where

  • (h, k) is the center
  • r is the radius

Typically, you are given the center and the radius.  In this problem, you are given (x, y) so you must plug that into the equation to find r².

Given: (x, y) = (-3, 4)   and   (h, k) = (1, 1)

                       (-3 - 1)² + (4 - 1)² = r²

                         (-4)²    +   (3)²   = r²

                          16      +    9     = r²

                                  25         = r²

Next, input (h, k) and r² into the equation

                  (x - 1)² + (y - 1)² = 25

Write 6(x – 5)4 + 4(x – 5)2 + 6 = 0 in the form of a quadratic by using substitution.
pogonyaev

We are given the equation:

6(x-5)^{4}+4(x-5)^{2}+6=0..........(1)

Now we have to write it in quadratic form using substitution.

The general form of quadratic equation is given by:

ax^{2}+bx+c=0

So let us say

(x-5)^{2}=u.......(2)

Plugging the value of (x-5)² from equation (2) in (1),

6u^{2}+4u+6=0

Answer : Option B. 6u^{2}+4u+6=0

If 9,309 is factored so that 29 is one of the factors, what number is the other factor
astra-53 [7]

answer: 321

work: factors are two numbers that are multiplied together to equal another number. so, the other factor is whatever the result of 9309/29 is. 9309/29= 321. so, the other factor is 321.
