Answer:

y = -¼│x − 5│+ 3

Step-by-step explanation:

y = a│x − h│+ k

(h, k) is the vertex of the absolute value graph. In this case, it's (5, 3).

y = a│x − 5│+ 3

One point on the graph is (1, 2). Plug in to find the value of a.

2 = a│1 − 5│+ 3

2 = 4a + 3

a = -¼

Therefore, the graph is:

y = -¼│x − 5│+ 3

Answer:

C. $Cos(28) = \frac{15}{17}$

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

$Cos(\theta) = \frac{Adjacent}{Hypotenuse}$

Reference angle = 28°

Adjacent = 15

Hypotenuse = 17

Plug in the values

$Cos(28) = \frac{15}{17}$

The steps to derive the quadratic formula are shown below:

Georgia [21]

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

Step-by-step explanation:

We can rewrite the left hand side as a perfect square, more specifically

$\left(x+\frac{b}{2a} \right)^2$

So, taking the square root of both sides,

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