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.

Answer:

5. 3/5-2/5=1/5; answer is 1/5

6.7/10-3/10=4/10; answer is 2/5(simplify)

7.5/6-4/6=1/6; answer is 1/6

8.3/4-2/4=1/4; answer is 1/4

Step-by-step explanation:

Explanation is above, when subtracting fractions remember that the denominator must be the same and you can subtract the numerator.

Hope this helps!

Answer:

5. 2/5 - 1/5 =1/5

6. 4/10 - 3/10 =1/10

7. 1/6 - 4/6 = -3/6

8. 1/4 - 2/4 = -1/4

Step-by-step explanation:

800 grams into ounces is 28.2, rounded to the nearest tenth.

The conversion of 800 grams into ounces is 28.2.

Since 1 ounce (oz) = 28.35 grams (g)

So for 800 grams the no of ounces should be 28.2.

Answer:

8x-20

Step-by-step explanation:

Distribute:

=(6)(2x)+(6)(−3)+(−2)(2x)+(−2)(1)

=12x+−18+−4x+−2

Combine Like Terms:

=12x+−18+−4x+−2

=(12x+−4x)+(−18+−2)

=8x+−20

Answer:

=8x−20

Answer:

We know that:

csc(x) = 1/sin(x)

Now we want to work with:

2csc(x+y)

The first step is:

2csc(x+y)= 2/sin(x-y)

This is correct so far.

Now we need to use the relation:

sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)

Then:

sin(x - y) = sin(x)*cos(-y) + sin(-y)*cos(x)

sin(x) is an odd function, then: sin(-y) = -sin(y)

and cos(x) is an even function, then:

cos(-y) = cos(y)

Then we get:

sin(x - y) = sin(x)*cos(y) - sin(y)*cos(x)

then:

2/sin(x-y) = 2/(sin(x)*cos(y) - sin(y)*cos(x))

Now let's look at what she did:

2/sin(x-y) = 2/(cos x cos(-y)+sin xsin(-y))

Here is her error, she replaced:

sin(x - y) by cos x cos(-y)+sin(x)sin(-y)

This relation is for the cosine function, not the sine one, so here is her mistake.

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)

^^^^thats all i know, i got the answer from my teacher tho lol

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.

i hope it helped :)

Answer:

-3(3+20w)

Step-by-step explanation:

Factor the expression

Answer:

40/49

Step-by-step explanation:

One way to answer this is to ask the opposite question.

What is the probability that neither will show a number 4 or more?

That would mean BOTH have to each be a 3 or less.

For the first die to show 3 or less       -->  probability = 3/7

For the second die to show 3 or less -->  probability = 3/7

For them BOTH to show 3 or less       -->  probability = 3/7 * 3/7 = 9/49

Probability a thing happens + probability it doesn't happen = 1. Always.

Prob(both dice 3 or less) + Prob(at least one die 4 or more) = 1

So, Prob(at least one die 4 or more) = 1 - Prob(both dice 3 or less)

                                                            = 1 - 9/49

                                                            = 49/49 - 9/49

                                                             = 40/49

The probability of having atleast one dice with a value greater than or equal to 4 is 0.8163

Using a sample space which is attached below :

Recall :

Probability = required outcome / Total possible outcomes

Required outcomes = 40

Total possible outcomes = 7² = 49

The probability of having atleast one dice with a value greater than or equal to 4 will be :

Probability = 40 / 49 = 0.8163
