Answer:

Step-by-step explanation:

Put the equation in the form ax+by+c=0:

$y\sqrt{3} =8x+\sqrt{3} \\=>8x-\sqrt{3} y+\sqrt{3} =0$

Check the solutions:

$(0,-1)$ :

$8(0)-\sqrt{3} (-1)+\sqrt{3} =2\sqrt{3}$

So this is not a solution.

( $(\sqrt{3} ,9)$ :

$8\sqrt{3} -9\sqrt{3} +\sqrt{3} =0$

So this is a solution

Suppose a ball is thrown directly upward from a height of 7 feet with an initial velocity of 50 feet per second. Use the quadrat

Fittoniya [83]

Answer:

t = 3.3 seconds

Step-by-step explanation:

From the formula of vertical motion of an object under gravity we can write the equation

$H = ut + \frac{1}{2} gt^{2}$ ....... (1)

Where u is the initial velocity (in feet per second) of throw of the object and t is time of travel in seconds and the value of g i.e. gravitational acceleration is 32 feet/sec².

Now, while a ball is thrown vertically upward with velocity 50 ft/sec from a height of 7 ft then the time of travel of the ball before reaching the ground, the equation (1) will be written as

$- 7 = 50t - \frac{1}{2} \times 32 \times t^{2}$

As we have selected the upward direction as positive so, gravitational acceleration,g will be negative and as the displacement is downward by 7 feet, so it will be negative.

⇒ 16t² - 50t - 7 = 0 ........ (2)

Now, applying Sridhar Acharya formula,

$t = \frac{-(-50) + \sqrt{(-50)^{2} - 4(16)(-7)}}{2(16)}$ {Neglecting the negative root as t can not be negative}

⇒ t = 3.3 seconds {Rounded to the nearest tenth}

The pizza is cut in three equal sections

And, then it gave to her four kids

So,

The part of the pizza that she give to her kids is one-third of the pizza gone for each and every kid

Comedy Drama Action Horror

Neporo4naja [7]

Answer:

B. Drama is the most popular genre

Step-by-step explanation:

⇒ Comedy: 5

Drama: 7

Action: 3

Horror: 1

⇒ Comedy: 2

Drama: 11

Action: 4

Horror: 5

<h3 /><h3>With this information we can start ruling out our answer choices.</h3>

<u>A. horror is the most popular genre</u>

Lets see, both of the sum of both days for <u>Horror is 6</u>, for <u>Action is 7,</u> <u>Drama is 18,</u> and <u>Comedy is 7, </u>with this we can conclude that<u> </u><u><em>horror is actually the least popular genre</em></u>

<u>B. Drama is the most popular genre</u>

Using the information we gathered previously, we know <u>Drama is the most popular genre</u>, therefore this option is a high possibility.

<u>C. People like comedies because they like to laugh</u>

Although, I personally love comedies for this reason, <u>this chart does not prove that people like comedies for this reason.</u>

<u>D. People don't like horror movies because they don't like to be scared</u>

As for option C, the <u>chart does not prove that is the case!</u>

<h3>Therefore we can conclude that <u>option B</u> is the best choice.</h3>
