The price of Stock A at 9 A.M. was ​$12.95 Since​ then, the price has been increasing at the rate of ​$0.12 each hour. At noon the price of Stock B was ​$13.70. It begins to decrease at the rate of ​$0.13 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Answers

Answer:

The prices of the two stocks will be the same in 1.56 hours.

Step-by-step explanation:

The price of Stock A at 9 A.M. was ​$12.95 Since​ then, the price has been increasing at the rate of ​$0.12 each hour.

This means that after x hours, the value of Stock A is:

[tex]S_{A}(x) = 12.95 + 0.12x[/tex]

After noon:

Noon is 3 hours after 9 AM, so

[tex]S_{A}(3) = 12.95 + 0.12*3 = 13.31[/tex]

So in x hours after noon, the value is given by:

[tex]S_{A}(x) = 13.31 + 0.12x[/tex]

At noon the price of Stock B was ​$13.70. It begins to decrease at the rate of ​$0.13 each hour.

This means that after x hours, the value of Stock B is:

[tex]S_{B}(x) = 13.70 - 0.13x[/tex]

In how many hours will the prices of the two stocks be the​ same?

This is x for which:

[tex]S_{A}(x) = S_{B}(x)[/tex]

[tex]13.31 + 0.12x = 13.70 - 0.13x[/tex]

[tex]0.25x = 0.39[/tex]

[tex]x = \frac{0.39}{0.25}[/tex]

[tex]x = 1.56[/tex]

The prices of the two stocks will be the same in 1.56 hours.

A salesperson receives a 3% commission on sales. The salesperson receives $180 in commission. What is the amount of sales?

Thank you :)

Answers

Answer:

$6,000

Step-by-step explanation:

Form an equation

let s be the amount of sales

You know that the salesperson gets 3%, or 0.03 of the sales, so:

0.03x = 180

Then, solve

[tex]0.03x=180[/tex]

multiply both sides by 100 to get rid of the decimal

[tex]3x=18000[/tex]

divide both sides by 3

[tex]x=6000[/tex]

So the amount of sales is $6,000

Please someone help I need help so bad I’m so scared I’m gonna fail this test I may get held back if I fail this test please help me

Answers

Use elimination to cancel y. Add both systems together:
2x + 8x - y + y = 10 + 20

Combine like terms:
10x = 30

Divide by 10:
x = 3

Plug x back in to solve for y:
2(3) - y = 10
6 - y = 10

Subtract 6:
-y = 4

Divide by -1:
y = -4


So your solution is x = 3 and y = -4 which is also written as (3, -4).

Answer:

  (2/3)(e^t +1)^(3/2)

Step-by-step explanation:

Use the substitution ...

  u = e^t +1

Then du = e^t and you are finding the integral of ...

  ∫u^(1/2)·du

which you know by the power rule is ...

  (2/3)u^(3/2) = (2/3)(e^t +1)^(3/2)


Which of the following is the minimum value of the equation y = 3x2 - 4x - 2?

Answers

Answer: 3x

Step-by-step explanation:

*Remember BIDMAS*

b- brackets i- Indices (exponents) d- division m- multiplication a- addition s- subtraction

(*Reminder* exponents can be written on a keyboard like 2 squared is 2^2)

you need to follow these steps to be able to solve any equation

if there is no brackets like yours then add to make it easier

3x^2 - 4x - 2 = (3x^2) - 4x - 2

From the steps I showed you indices is first so 3x multiplied by 3x is 9x  

now there is nothing left except for subtraction so solve from left to right always so 9x - 4x - 2 is 5x then 5x - 2 is 3x, x doesn’t change or gets subtracted.

The price listed for 4 dinner plates at a home store is $23.88. What amount will Jane need to pay, if she decides to purchase 10 such dinner plates?

Answers

If you want to answer this, then you’ll first have to figure out how much money the one plate costs. So you would divide $23.88 by 4 and the number you get is how much they paid for one plate.

Next you would have to take the number you get from the division problem and multiply that by 10. That will give you your answer for how much she will need to pay.

Work:
$23.88 / 4 = 5.97
5.97 x 10 = 59.70

She needs to pay $59.70 for the plates.

Mean:
Median :
Mode :
Range :

Answers

Answer:

Mean: 12.857

Median: 13

Mode: 15

Range: 9

Step-by-step explanation:

First, let's define what each of these terms mean.

Mean is the average of all the numbers in a set of data. Median is the number in the middle of a set of data after being put in ascending order. Mode is the number most frequently seen in a set of data. Range is the difference between the largest and the smallest number in a set of data.

First, let's go ahead and put all our terms in ascending order. It'll look like this: 8, 10, 12, 13, 15, 15, 17.

To find our mean, we'll add up all the terms and divide them by how many there are. First, we'll add up 8 + 10 + 12... and so on for a total of 90. Next, we'll divide 90 by 7 since there are 7 different terms in our set. 90 / 7 should roughly give you a mean of 12.857, but you can round it as needed.

Next, we'll find the median. The median is the number that is in the exact middle of a set once the terms are put in ascending order. Since, we put our terms in order already, we can see that the number in the middle of our set is 13, and I underlined it in the set to give you a visual!

Next, we'll find the mode. The mode is the number most frequently seen in our set of data. Since 15 is listed the most frequently (twice) it is our mode!

Finally, we'll find the range. The range is just the biggest number minus the smallest number. Our biggest number here is 17, and our smallest number here is 8. Just do 17 - 8 for a range of 9. Let me know if you have any other questions!
