What are the zeros of the quadratic function f(x)=8x^2-16x-15

____ [38]

Step-by-step explanation:

<u>Step 1: Use the quadratic formula to find the zeros</u>

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

$x=\frac{-(-16)\pm \sqrt{(-16)^2-4(8)(-15)} }{2(8)}$

$x=\frac{16\pm \sqrt{736} }{16}$

$x=\frac{16\pm 4\sqrt{46} }{16}$

$x=\frac{4\pm \sqrt{46} }{4}$

Answer: $x=\frac{4\pm \sqrt{46} }{4}$

Find the tangents of the acute angles in the right triangle. Write each answer as a fraction.

Crank

Hi there! Look at the attachments along with my explanation. Before we are going to answer your problem, we need to know the basic Trigonometric Ratio first.

tanA = opposite/adjacent

Now see my attachments. The first attachment is the original image from your problem.

The second attachment is when we draw to focus on angle H (in a better perspective)

The third attachment is when we draw to focus on angle G in a better perspective.

Now that we know tanA = opposite/adjacent

Define A = any angles.

Therefore,

tanH = 1/2

tanG = 2/1 = 2

Answer

tanG = 2
tanH = 1/2
