We have the following expression:
 y = (v ^ 2) / (2 * a)
 We must clear v from the equation.
 For this, we follow the following steps:
 Step 1)
 Pass 2 * a to multiply:
 2 * a * y = v ^ 2
 Step 2)
 Square root on both sides:
 root (2 * a * y) = v
 Step 3)
 Rewrite expression:
 v = root (2 * a * y)
 Answer:
 
v = root (2 * a * y)

If an angle measuring 20 is bisected to form two new angles, what is the measure of each new angle
alexgriva [62]

Answer:

10 degrees

Step-by-step explanation:

Bisection means dividing into two equal parts

So, if we bisect an angle measuring 20 degrees

It will divide into 2 equal parts and:

=> 20/2 = 10 degrees

Two angles of 10 degrees will be formed.

A students work to simplify a radical is shown below. Select the statemmebt which best applies to rhe sample mathematical work
Alik [6]

Answer:

D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further.

Step-by-step explanation:

If you add all the exponents of y in first line then we get

4+4+4+4+4+3=23

Which is same as the exponent in original problem.

So first line is good.

Since it is 4th root so each y^4 will turn into y when it moves out of the radical so final answer is correct.

Hence correct choice is "D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further." is the correct answer.

What is the solution to -7=-(x-5)
saul85 [17]

-7= -(x-5)

Step 1: Distribute the secret -1 behind the parentheses so -1(x-5) is -1x+5

Step 2:-7= -1x+5 Subtract 5 from both sides --> -12=-1x

Step 3: Divide both sides by -1 so -12/-1 and -1x/-1

x=12
