2. Solve the equation using the quadratic formula. -4x2 + 40x + 16 = 0 Page 1 of 2

kumpel [21]

The solution to given quadratic equation is x = -0.3851 or x = 10.3851

Solution:

Given equation is:

$-4x^2 + 40x + 16 = 0$

To find: solve by quadratic equation formula

$\text {For a quadratic equation } a x^{2}+b x+c=0, \text { where } a \neq 0\\\\x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Using the above formula,

$\text{ For} -4x^2 + 40x + 16 = 0 \text{ we have } a = -4 ; b = 40 ; c = 16$

Substituting the values of a = -4 ; b = 40 ; c = 16 in above quadratic formula we get,

$\begin{aligned}&x=\frac{-40 \pm \sqrt{40^{2}-4(-4)(16)}}{2 \times-4}\\\\&x=\frac{-40 \pm \sqrt{1600+256}}{-8}\\\\&x=\frac{-40 \pm 43.081}{-8}\\\\&x=\frac{-40+43.081}{-8} \text { or } x=\frac{-40-43.081}{-8}\\\\&x=-0.3851 \text { or } x=10.3851\end{aligned}$

Thus the solution to given quadratic equation is x = - 0.3851 or x = 10.3851

Given that (9,-8) is on the graph of f(x), find the corresponding point for the function f(x-2)

MrRa [10]

Answer:

(11,-8)

Step-by-step explanation:

f(x-2) determines a horizontal translation 2 units to the right. Since (9,-8) is the point for f(x) then f(x-2) will be the point (11,-8) where 9 has moved two units to the right 11.

A stain glass window is shaped like a semicircle. The bottom edge of the window is 36 inches long. What is the area of the stain

Lubov Fominskaja [6]

I don't really have a calculator on me. But I'll tell you how to go through it.
So the formula for the area of a circle is Pi x radius^2.
So since the diameter is 36, divide that by 2 to get the radius, and you're left with 18. Now do 18 squared and then times that by Pi. Now you've got the area of the whole circle, but since we only have a semicircle, you need to divide your answer by two to get the area of the semi circle
