Answer:

(x-5)^2+(y-1)^2=20

Step-by-step explanation:

<u>Equation of a circle</u>

(x-a)^2+(y-b)^2=r^2

(where (a, b) is the center and r is the radius)

Given:

  • center = (5, 1)
  • diameter = 4√5

Diameter = 2r (where r is the radius)

⇒ r = 4√5 ÷ 2 = 2√5

Substituting these values into the equation:

\implies (x-5)^2+(y-1)^2=(2\sqrt{5})^2

\implies (x-5)^2+(y-1)^2=20

Answer:

Using the distance formula, when I plugged in the information, the answer I got was the square root of 85. (B)

explanation:

C(x₁ , y₁) and T(x₂ , y₂) OR C(0,4) and T(-6,-3)

CT=√[(x₂ - x₁)² + (y₂ - y₁)²] =√[(-6-0)² + (-3 - 4)²]

CT=√[(36) + (49)} = CT = √85

is the following statement sometimes,always or never true?negative - positive =negative defend your answer
Elanso [62]
It is always negative, because it keeps going down on the number line. Say it is negative 8 minus 5, it would be negative 13, because it adds to the negatives, so it would go deeper into the negatives.

What is the greatest common factor (gcf) of the numerator and denominator in the rational expression below? 7x+14/2x^2+x-6
Mashutka [201]
The answer is C. The numerator 7x+14 can be factored as 7(x+2). The denominator 2x^2+2x-6 can be factored as (x+2)(2x-3). The greatest common divisor of 7(x+2) and (x+2)(2x-3) is obviously x+2, which is contained in both of the two expressions.
