Write the equation of a circle with a center at (-1,2) and a radius of 7

Sever21 [200]

Answer:

$(x+1)^2+(y-2)^2=49$

Step-by-step explanation:

The standard form for the equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where r is the radius, and the center is (h, k).

(h, k) = (-1, 2), r = 7

$(x-(-1))^2+(y-2)^2=7^2\\\\(x+1)^2+(y-2)^2=49$

Solve the equation, , using the quadratic formula.

N76 [4]

Answer:

$x=1\ or\ x=-\frac{1}{2}$

Step-by-step explanation:

To solve the given quadratic equation $2x^2-x-1=0$ you can apply the Quadratic formula, which is shown below:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

Where:

$a=2\\b=-1\\c=-1$

Therefore, when you substitute values into the Quadratic formula shown above, you obtain the following solution:

$x=\frac{-(-1)\±\sqrt{(-1)^2-4(2)(-1)}}{2*2}$

$x=1\ or\ x=-\frac{1}{2}$
