Answer:

(x - 4)² + (y - 5)² = 4

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

Given

(x - 4)² + (y - 5)² = 2

with centre (4, 5) and r = $\sqrt{2}$

The comparable equation with equivalent left side and r = 2 is

(x - 4)² + (y - 5)² = 4

What value of b makes the polynomial below a perfect square?

Marina CMI [18]

Polynomials are perfect squares when the first term (term x2) and the third term (term 49) are both squares. In order to find the value of b, you must take the square root of the third term and multiply by the exponent in the first term. This means since the sqrt(49) is 7, and 7x2=14; then the correct answer is C. 14.

-- Remember this only works on perfect square polynomials.

Give the equation of the circle whose center is (5 -3) and goes through (2 5)

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

The standard form for the equation of a circle is

$(x-h)^2+(y-k)^2=r^2$

From the info given, we have the center, (h, k) as (5, -3) and the x and y coordinates of (2, 5). We will use these to solve for r-squared, then plug back in what we need to write the equation.

$(2-5)^2+(5-(-3))^2=r^2$ which simplifies to
