How do i Factor 4w^2=24w

Mathematics
1 answer:
Sophie [7]3 years ago
7 0

Simplifying

4w2 + 24w = 0


Reorder the terms:

24w + 4w2 = 0


Solving

24w + 4w2 = 0


Solving for variable 'w'.


Factor out the Greatest Common Factor (GCF), '4w'.

4w(6 + w) = 0


Ignore the factor 4.

Subproblem 1

Set the factor 'w' equal to zero and attempt to solve:


Simplifying

w = 0


Solving

w = 0


Move all terms containing w to the left, all other terms to the right.


Simplifying

w = 0

Subproblem 2

Set the factor '(6 + w)' equal to zero and attempt to solve:


Simplifying

6 + w = 0


Solving

6 + w = 0


Move all terms containing w to the left, all other terms to the right.


Add '-6' to each side of the equation.

6 + -6 + w = 0 + -6


Combine like terms: 6 + -6 = 0

0 + w = 0 + -6

w = 0 + -6


Combine like terms: 0 + -6 = -6

w = -6


Simplifying

w = -6

Solution

w = {0, -6}

A wheel with radius 1 foot makes 1 revolution in 4 seconds. What is the linear velocity, in feet per second, of a point on the e
Alex

Answer:

v=\dfrac{\pi}{2}\ ft/s

Step-by-step explanation:

Given that,

A wheel with radius 1 foot makes 1 revolution in 4 seconds

We need to find the linera velocity of a point on the edge of the wheel. We know that, the linear velcity is given by :

v=r\omega

Where

\omega is angular velcocity,\omega=2\pi\ rad

\omega=\dfrac{1}{4}\times 2\pi\\\\=0.5\pi\ rad/s

So

v=1\times 0.5\pi\\\\v=\dfrac{\pi}{2}\ ft/s

So, the linear velocity of the wheel is equal to \dfrac{\pi}{2}\ ft/s.

babunello [35]
<h2>L+T = 8</h2><h2>T = 2L -1</h2>

Step-by-step explanation:

Let the number of lions be represented by L

Let the number of tigers be represented by T

<u>A zoo has a total of 8 lions and tigers</u><u> </u><u>:</u>

<u>L + T= 8</u>

<u>Th</u><u>e number of tigers are one less than twice the number of lions.</u><u> </u><u>:</u>

T = 2L -1

To ensure he never eats the whole cake, Bobby only decides to eat half of what’s left for each serving. If 2/3 of the cake are l
siniylev [52]
1st serving: 2/3 * 1/2 = 2/6 or 1/3
2nd serving: 1/3 * 1/2 = 1/6
3rd serving: 1/6 * 1/2 = 1/12
4th serving: 1/12 * 1/2 = 1/24
5th serving: 1/24 * 1/2 = 1/48

1/3 + 1/6 + 1/12 + 1/24 + 1/48 
1/3 * 16/16 = 16/48
1/6 * 8/8 = 8/48
1/12 * 4/4 = 4/48
1/24 * 2/2 = 2/48
1/48 * 1/1 = 1/48

16/48 + 8/48 + 4/48 + 2/48 + 1/48 = 31/48

Bobby ate 31/48 of the cake in total.

Maria is play a game where you score -5 points each time you guess the correct answer.The goal is to get the lowest score.To win
oee [108]

Answer:

7

Step-by-step explanation:

Just notice that correct answers are whole numbers.

And, to win the game,Maria must have a score less than -80, it means she needs to score al least -85 ( it can not be -81, -82.. because 1 correct answer score -5, only multiples of -5 are accepted)

So,  we take: \frac{-85}{-5} = 7 correct answers to win the game.

Hope it will find you well.
