Given data:
The given equationn of the circle is (x + 1)^2 + (y - 5)^2 = 16.
The standard equation of the circle is,

The given equation can eb written as,

Compare the above equation with standard equation.

Thus, the coordinate of centre is (-1, 5) and radius is 4.
Answer:
5=5=10
Step-by-step explanation:
Answer:
95 - 20 = <em>t</em>
Step-by-step explanation:
Let's start with the facts. You know that Mike's test score is 20 points lower than Mark's. You know that Mark's score was 95.
If we are trying to find Mike's test score, <em>t</em>, the equation would be this:
The equation would be 95 - 20 = <em>t</em>

The given function is

. This is a quadratic function because the degree of the polynomial, the variable with the highest exponent, is 2.
All quadratic functions can be expressed in the form

.
In your equation,
a = -1
b = 50
c = -264
The equation for the x-coordinate vertex of a quadratic function is

.
Applying this to the given function,

.
Now plug the value of x into f(x) to find f(x) (aka the y-coordinate).

The vertex is (25, 361)
Part B
The x-intercept is where the graph crosses the x-axis. Therefore, f(x) (aka the y-coordinate) will be 0. So the x-intercept will be in the form of (x, 0).
To find the x-intercept, set f(x) = 0.

.
Therefore the x-intercepts will be at (6, 0) and (44, 0)
