\(\sqrt{\frac{p}{2}-2 } = \sqrt{p-8}\)

Answers

Answer 1

\(\boldsymbol{\sqrt{\dfrac{p}{2}-2}=\sqrt{p-8}}\)

Cancel the square root on both sides.

\(\boldsymbol{\sf{\dfrac{p}{-2}-2=\sqrt{p-8} }}\)

Multiply both sides by 2.

\(\boldsymbol{\sf{p-4=2p-16 }}\)

Subtract p from both sides.

\(\boldsymbol{\sf{-4=2p-16-p }}\)

Simplify

\(\boldsymbol{\sf{-4=p-16 }}\)

Add 16 to both sides.

\(\boldsymbol{\sf{-4+16=p }}\)

Simplify

\(\boldsymbol{\sf{12=p}}\)

Swap sides.

\(\boldsymbol{\sf{p=12 \ \ \to \ \ \ Answer}}\)

Verification

\(\boldsymbol{\sqrt{\dfrac{p}{2}-2}=\sqrt{p-8} \ \ \to \ \ \ Exercise \ normal.}\)

Let p=12.

\(\boldsymbol{\sqrt{\dfrac{12}{2}-2}=\sqrt{12-8}}\)

Simplify 12/6 to 6.

\(\boldsymbol{\sqrt{6-4}=\sqrt{12-8} }\)

Simplify 6-2 to 4.

\(\boldsymbol{\sqrt{4}=\sqrt{12-8} }\)

Since 2×2=4, the square root of 4 is 2.

\(\boldsymbol{2=\sqrt{12-8} }\)

Simplify 12-8 to 4.

\(\boldsymbol{2=\sqrt{4} }\)

Since 2×2=4, the square root of 4 is 2.

Brenlyn's boss told her that once she has worked with the company for 10 years, her salary will be increased to 3 times what she makes now plus $2,000. If s represents her original salary, Which expression represents what her salary will be after 10 years at the company?

Answers

Answer:

3s + 2000 = x

Step-by-step explanation:

So, her original salary, s, will be tripled after 10 years. Hence 3 multiplied by "s" her original salary. Then you see the keyword "plus" 2000. So you would just add on to that. That's how you get 3s + 2000 = x (her salary after 10 years.)

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
please help me i will give brainliest to first person to anwser.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value

Answers

The value of A/B is given as follows:

A/B = -2.

What are the asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Answers

Answer:

  a.  12

  b.  1/2

Step-by-step explanation:

Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.

a. Possibilities

As the tree diagram shows, the number of possible meals is ...

  (possible meats)×(possible fruits)×(possible desserts)

  = 3×2×2 = 12

There are 12 possible lunch options.

b. Cookies

Half the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:

  P(no cookie) = 1/2

__

Additional comment

The bottom line of the tree diagram has 6 Cs and 6 Ms. That is, 6 of the 12 options for meals have no cookie.

At the beginning of the school year, 70 students signed up for music lessons. Students could choose drums, guitar, piano, or violin. The results are shown in the table. Which is a true statement about this situation?


Instrument Boys Girls

Drums 11 6

Guitar 6 8

Piano 9 15

Violin 4 11

A.

About 28% of students signed up for violin lessons.


B.

About 17% of students signed up for drum lessons.


C.

A greater percent of boys are taking piano lessons than girls.


D.

The same percent of boys and girls are taking guitar lessons.

Answers

Answer:

D.

Step-by-step explanation:

1. Answer A:

15 students signed up for violin lessons (4 boys + 11 girls)

15 / 70 = approx. 21% of the class.

Answer A says 28%, so this is incorrect.

2. Answer B:

17 students signed up for drum lessons (11 boys + 6 girls)

17/70 = approx. 24%

B says 17% signed up for drums, so this is incorrect.

3. Answer C.

Wrong because more girls signed up for piano lessons (15 girls, whereas only 9 boys signed up for piano)

4. D. The same percent of boys and girls are taking guitar lessons.

Get the total number of boys and girls in the class (just add the results for each separately for all instruments)

Boys: 11 + 6 + 9 + 4 = 30

Girls: 6+8+15+11 = 40

6 out of 30 boys signed up for guitar

6/30= 20%

8 out of 40 girls signed up for guitar

8/40 = 20%

Step 3: -110 = 22x

Step 4: -5 = x

Answers

when multiplying -2 by 7 the answer will be -14 instead of 7 so the answer will be like this
