A circle has its center at (-2,3) and a radius of 5. What is the equation for the circle?
DanielleElmas [232]
Since the equation for a circle is (x-h)^2+(y-h)^2=r^2, with the center being (h,k) and the radius being r, we can plug it in to get (x-(-2))^2+(y-3)^2=5^2
=(x+2)^2+(y-3)^2=25

If f(x) = 4x3 - 2x and g(x) = x3 + 6x2 + 3x - 7, then find f(x)<br> + g(x)
leva [86]

Answer:

5x^3+6x^2+x-7

Step-by-step explanation:

f(x) = 4x^3 - 2x and g(x) = x^3 + 6x^2 + 3x - 7,

f(x) + g(x)= 4x^3 - 2x+ x^3 + 6x^2 + 3x - 7

               4x^3 + x^3 + 6x^2 + 3x- 2x - 7

Combine like terms

5x^3+6x^2+x-7

What are the solutions to the quadratic equation x^2-16=0
maks197457 [2]
Good evening.


This is a incomplete quadratic equation, because it does not have the term bx. Therefore, we can solve this faster with the following strategy:

\mathsf{x^2 - 16 = 0}

Add 16 to both sides:

\mathsf{x^2 - 16 + 16 = 0 + 16}\\ \\ \mathsf{x^2 = 16}

Take the square root:

\mathsf{\sqrt {x^2} = \pm\sqrt{16}}\\ \\ \mathsf{\boxed{\mathsf{x = \pm4} }}

Therefore:

\boxed{\boxed{\mathsf{S=\{-4, \ +4\}}}}
