What are the solutions to the quadratic equation 9x(2) + 64 = 0?

Contact [7]

Answer:

Solution of given quadratic equation is

$(\frac{8i}{3}, -\frac{8i}{3} )$

Step-by-step explanation:

The given quadratic equation is

$9x^2 + 64 = 0$

The general form of the quadratic equation is given by

$ax^2 + bx + c = 0$

Comparing the general form with the given quadratic equation

$a = 9\\b = 0\\c = 64$

The solutions of the quadratic equation is given by

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Substitute the values of a, b and c

$x=\frac{-0\pm\sqrt{0^2-4(9)(64)}}{2(9)}$

$x=\frac{\pm\sqrt{-2304}}{18}$

$x=\frac{\pm48i}{18}$

$x=\frac{\pm8i}{3}$

$x=\frac{8i}{3}$

and

$x=-\frac{8i}{3}$

Where i represents iota which means that the given quadratic equation has complex roots.

So the solution of given quadratic equation is

$(\frac{8i}{3}, -\frac{8i}{3} )$

The factored form of the given quadratic equation is

$(x+ \frac{8i}{3}) (x- \frac{8i}{3}) = 0$

Nick has four (4) quarters and eight (8) dimes in his pocket.

Four quarters equals to a dollar and eight dimes equals eighty cents.
Four plus eight is twelve.

Help me with the diagram please!!!

Answer:

(B) 30

Step-by-step explanation:

Imagine you drew a line from Point T until it touched Line PR. Let's call that point where it touched Line PR "Point Z".

That line (called Line TZ) would be perpendicular to PR, forming a 90 degree angle.

Now, TZW is a triangle.

To find x, we need to find the angle measurment of Angle ZTW.

This is where we use the hexagon.

A hexagon's interior angle sum is 720, meaning each interior angle is equal to 120 degrees. So Angle UTS would equal 120 degrees.

However, Line TZ bisects that 120 degree angle, so Angle ZTW would equal 60 degrees (because 120/2 = 60).

Now we have two angles of the triangle: 90 & 60.

A triangle's interior angle sum is 180.

Add 90 & 60, which is 150, and subtract 150 from 180.

The result is 30, which is the angle measurement of x.

Hope it helps (●'◡'●)
