Find the value of p3- q3, if p-q = -7 and pq= -10

Answers

Answer:   -133

===================================================

Work Shown:

p-q = -7

(p-q)^2 = (-7)^2

p^2-2pq+q^2 = 49

p^2-2(-10)+q^2 = 49

p^2+20+q^2 = 49

p^2+q^2 = 49-20

p^2+q^2 = 29

By the difference of cubes formula, we can say,

p^3 - q^3 = (p-q)*(p^2+pq+q^2)

p^3 - q^3 = (p-q)*(p^2+q^2+pq)

p^3 - q^3 = (-7)*(29-10)

p^3 - q^3 = -133

--------------

Here's another way to solve:

p-q = -7

p = q-7

pq = -10

(q-7)*q = -10

q^2-7q = -10

q^2-7q+10 = 0

(q-5)(q-2) = 0

q-5 = 0 or q-2 = 0

q = 5 or q = 2

If q = 5, then p = q-7 = 5-7 = -2

If q = 2, then p = q-7 = 2-7 = -5

We can see that no matter what we pick for q, we'll get p*q = -10

Also, you should find that p^3-q^3 is equal to -133 for either case as well.

Zeke owns stock in a high-tech firm. Each share is currently valued at $21 per share, which is 30% less than Zeke paid to purchase it. What did Zeke pay per share?

Answers

Answer:

$14.7

Step-by-step explanation:

Zeke owns stock in a high tech firm

Each share is valued at $21

It's is 30% less than the amount it was purchased

Therefore Zeke pay per share can be calculated as follows

= 21× 30/100

= 21×0.3

= 6.3

= 21-6.3

= 14.7

Hence Zeke's pay per share is $14.7

Answers

Answer:

True

Step-by-step explanation:

Smoking damages your entire cardiovascular system. Speaking of this Nicotine causes blood vessels to tighten, which restricts the flow of blood. Over time, the ongoing narrowing, along with damage to the blood vessels, can cause *peripheral artery disease*. Smoking also raises blood pressure, weakens blood vessel walls, and increases blood clots.

* Peripheral artery disease is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs

10/15

Hi! The answer is true because if you divide 6/4 you get 1.5 so 1.5 X 4 is 6 so you know that is proportional and 15/10 is 1.5 so you know that is proportional as well.

1.5 X 4 = 6
1.5 X 10 = 15

Since they both equal 1.5 after you divide them you know it’s proportional. I hope this helped, Goodluck :)

Answers

Answer:

Options A and E

Step-by-step explanation:

Isosceles triangle → Two sides and opposite angles of the equal sides will be equal

In the given triangle measure of all sides are different.

Therefore, it's not an isosceles triangle.

Equilateral triangle → All sides and opposite angles are equal.

Given triangle is not an equilateral triangle.

Scalene triangle → All sides and angles are different in measure.

It's an scalene triangle.

Since, one angle of the triangle is a right triangle, it's a right triangle.

Option A and E are the correct options.

The rules of a game allow a team to score either 2 points or 5 points, depending on the nature of the scoring play. If the final score between two teams was 34 to 29, and there were 18 scoring plays altogether, how many 5-point plays were there?

Answers

Answer:

9

Step-by-step explanation:

Given that :

Total Number of scorings (both Teams) = 18

Let :

x = number of 5 point score ; y = number of 2 point score

Total points scored = 34 + 29 = 63

x + y = 18 - - - (1)

5x + 2y = 63 - - (2)

From (1)

y = 18 - x

In (2) ; we have ;

5x + 2(18 - x) = 63

5x + 36 - 2x = 63

3x + 36 = 63

3x = 63 - 36

3x = 27

x = 9

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out the maximum amount of profit the company can make, to the nearest dollar. y=-2x^2+105x-859 y=−2x 2 +105x−859

Answers

Answer:

$519

Step-by-step explanation:

Given the amount of profit made expressed as y=-2x^2+105x-859

At maximum profit, dy/dx = 0

dy/dx = -4x + 105

0 = -4x + 105

4x = 105

x = 105/4

x = 26.25

Substitute into the original function

y=-2x^2+105x-859

y=-2(26.25)^2+105(26.25)-859

y = - 1,378.125+2,756.25-859

y = 519.125

Hence the maximum amount of profit the company can make is $519

A Three-Point TurnChapter 1"You know, hardly anyone ever needs to do a three-point turn anymore," said Justin, trying to help Becky calm down."Oh, so it's not a useful skill AND I am probably going to fail the driving test because I can't do it anyway," Becky said, raising her voice for emphasis. "That should make me feel like a million bucks when I flunk."Justin was riding with Becky so she could take her driving test. He had volunteered for the job because he thought she would be less nervous with him than with their mom, but so far, he wasn't sure he was making any difference."Slow down, your turn is coming up here," he said, looking ahead."I know, I know," she replied, "I've been here before rememberthe last time I flunked."Justin was pretty sure if he had let her miss the turn, things would only have deteriorated further, but he wasn't sure he was fond of being the scapegoat for Becky's anxiety."Listen, you need to take a few deep breaths," he said, hoping he could help her at least relax a bit. "Being nervous won't help you with the three-point turn or anything else you have to do. Hey, did you just take that turn without your turn signal on?" This was going to be harder than he thought."Stop yelling at me," Becky replied, clearly frustrated, "I can't concentrate.""Look, you need to stop and get yourself together here," Justin started. "It is not just about passing the driving test. I don't want to get in an accident, so pull into that parking lot."Becky drove into the office building's parking lot where Justin was pointing. Justin knew they were less than a mile from the licensing office, and if she continued in this condition, he'd be having this same discussion three months from now when she tried the test again for the third time."You need to get a grip," he started after she put the car in park, "because you have studied and practiced driving all year. You know this stuff inside and out, backwards and forwards. What are you so nervous about?""I don't know, I don't know," Becky wailed, resting her head on the steering wheel. "I just get so tired of failing."Listening quietly as Becky sobbed, Justin realized this was about much more than a driving test. He also knew if he didn't find a way to help Becky things would just get worse.Chapter 2Justin took a deep breath and collected his thoughts. Becky was an unbelievably consistent straight-A student. It was Justin who got the bad grades in school, and Justin who had to repeat every math class he'd ever taken. It was Justin who wished he could get the grades Becky got. Some things came easier for Justin: He was athletic, handy with tools, and good at making the best of whatever life threw at him. Mom called him her "lemons into lemonade" kid. But for the most part, Becky succeeded easily, whereas Justin had to work and work to just get a passing grade.Rather than having Becky catalogue all the things she supposedly "failed" at, Justin decided to try an alternative approach, one that wouldn't remind him of all the ways he had failed."Okay, Becky, let's assume for a moment you fail this test again. What is the worst thing that could happen?" he asked."I would be the oldest kid at school without a license and be humiliated," she replied. Justin thought he heard a bit of panic in her voice but continued with his plan."Yes, but won't we still have to drive to school together for at least one more year anyway?" he asked."Yes, but..." she started."And who will know, if you don't tell anyone except your friends, that you don't have your license? You know Mom can't afford another car just for you, right?""Yes," she said quietly."So what difference does it make, really," he said. "Another three months to wait in the grand scheme of your life doesn't seem like all that long, right?""I suppose not," she said.Justin could tell she was breathing more slowly now. "Besides," he said, "I would miss all the practice driving with you," and for good measure he reached over and pinched her arm."Ow," she said, hitting back at him, "that hurt.""So let's go do this, okay?"Okay," she said. Becky cranked up the car, backed slowly out of the parking spot and drove up to the parking lot's exit. Justin noticed, as they waited for the traffic to clear, that she had remembered the turn signal.Read this line from Chapter 1:"Stop yelling at me," Becky replied, clearly frustrated, "I can't concentrate."Which of the following has a more negative connotation than frustrated?
