Answer:

5 1/3

Step-by-step explanation:

<h2>Lesson: Adding or Sutracting Fractions</h2>

Convert mixed number to improper fraction.

3 5/6=23/6

23/6+3/2

23/6+9/6

Denominators are equal, and it should be combine the. fractions.

23+9/6

Add the numbers from left to right.

23+9=32

32/6

Make sure to cancel by the common factor of 2.

16/3

Convert improper fractions into the mixed number.

16/3=5 1/3

5 1/3 is the correct answer.

I hope this helps you, and have a wonderful day!

Use the Addition Formula for Cosine to prove the Double-Angle Formula for Cosine. cos(2x) = cos2(x) − sin2(x) Rewrite 2x as x +

andre [41]

Answer with Step-by-step explanation:

We are given that

LHS

$cos 2x$

To prove that

$cos 2x=cos^2x-sin^2 x$

$cos(x+x)$

We know that

$cos(x+y)=cos xcosy-sinx siny$

Using the formula

$cos(x+x)=cosx\cdot cosx-sinx\cdot sinx$

$cos2 x=cos^2 x-sin^2 x$

By using

$cosx\cdot cosx=cos^2 x$

$sinx\cdot sinx=sin^2 x$

LHS=RHS

Hence, proved.

Which of the following represents a function with the greatest rate of change?

defon

So the rate of change can be found in different places.

For the first one:

This equation is in slope-intercept form, or y = mx + b.

m would be the slope/rate of change, and b the y intercept. (x and y would just be any sets of ordered pairs that fit into the equation.)

So if you look at which number is in the m spot, or the rate of change spot, you see that 5 is the rate of change.

For the second one: The formula for slope is:

m = $\frac{ y_{2} - y_{1} }{x_{2} - x_{1} }$

So just put in any ordered pairs in. I'm just going to put in the ordered pairs, (6, 30) and (4, 22).

Or,

m = (30 - 22) / (6 - 4)

Or,

m = 8/2

Or 4.

For the third one:

You can use the same formula as I stated above.

So you have to look for two ordered pairs here, two points.

So you can estimate that two of the points are: (0, 3) and (-2, -9).

So then just solve for that.

(-9 - 3) / (-2 - 0) = -12 / -2 = 6

For the last one:

Again, use the same equation.

m = (7 - 1) / (-1 - (-3))

m = 6/2

m = 3

So the one with the greatest rate of change would be C.
