<h3><u>Option C</u></h3><h3><u>The vertex form of the equation is:</u></h3>

<em><u>Solution:</u></em>
<em><u>The vertex form of equation is given as:</u></em>

Where, (h, k) is the vertex
Given that,

We have to find the vertex form of equation
Step 1:
Complete the square for 

a = 1
b = -6
c = 14
Consider the vertex form of a parabola.

Substitute the values of a and b into following:

Find the value of "e" using following formula:

Substitute the values of a, d, e in eqn 1

Thus vertex form form is found. Option C is correct
Answer: 51°
Step-by-step explanation:
3:5
x:85°
85/5=17
3x17=51
So, 51° is the answer!
Hope this helped! ;)
Let, the time when <span>Jan cough up to Carol = x
We know, Distance = Speed * Time.
So, Equation would be: 2x + 5*2 = 6x
2x + 10 = 6x
6x - 2x = 10
4x = 10
x = 10/4 = 2.5
Distance traveled in that time = 2.5 * 6 = 15 miles
In short, Your Answer would be: 15 miles
Hope this helps!</span>
