Answer:

i am on this exact question and i am confused myself because it seems like the answer should be "180 degree rotation with a translation of 5 units to the right" but that is not an option :/ so my best guess is either A or D hope this helps at all

Consider the equation 5/3v + 4 + 1/3v = 8. What is the resulting equation after the first step in the solution?

BigorU [14]

You would combing like terms. In this case, it is 5/3v and 1/3v. So you would add them together to get 6/3v,or just 2 because 6 divided by 3 is 2. So now you have 2v+4=8.

The standard form of the equation of a parabola is y= x2 - 6x + 14.

Bas_tet [7]

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

$y = (x - 3)^2 + 5$

<em><u>Solution:</u></em>

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

$y = a(x- h)^2 + k$

Where, (h, k) is the vertex

Given that,

$y = x^2 - 6x + 14$

We have to find the vertex form of equation

Step 1:

Complete the square for $x^2 - 6x + 14$

$\text{ Use the form } ax^2 + bx + c \text{ to find values of a, b, c }$

a = 1

b = -6

c = 14

Consider the vertex form of a parabola.

$a(x + d)^2 + e ----- eqn 1$

Substitute the values of a and b into following:

$d = \frac{b}{2a}\\\\d = \frac{-6}{2 \times 1}\\\\d = -3$

Find the value of "e" using following formula:

$e = c - \frac{b^2}{4a}\\\\e = 14 - \frac{(-6)^2 }{4 \times 1}\\\\e = 14 - 9\\\\e = 5$

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

$y = 1(x -3)^2 + 5\\\\y = (x - 3)^2 + 5$

Thus vertex form form is found. Option C is correct

Which equation can be used to determine the reference angle, r, if 0=7 pi/12?

viktelen [127]

Answer:

$r=180-\frac{7\pi }{12}$

Step-by-step explanation:

To find the reference angle of a given angle, first of all, the quadrant of the given angle is determined.

So for 7pi/12

The quadrant is 2nd.

For the angle belonging to 2nd quadrant the equation for reference angle will be:

r=180 - theeta

$r=180-\frac{7\pi }{12}$
