The volume Vcm3 of fluid in a container at time t seconds can be modelled using the differential system dVdt=2V−15. If V=15cm3 at time t=0, calculate the volume of fluid in the container after 2 seconds. Give your answer to the nearest cubic centimetre. Do not include any other symbols or units in your answer.

Answers

The ODE is separable, as

dV/dt = 2V - 15   →   dV/(2V - 15) = dt

Integrate both sides to get

1/2 ln|2V - 15| = t + C

(To compute integral, consider substituting U = 2V - 15.)

The volume is V = 15 cm³ when t = 0, so that

1/2 ln(15) = C

and so the volume at any time t is such that

1/2 ln|2V - 15| = t + 1/2 ln(15)

Solve for V :

ln|2V - 15| = 2t + ln(15)

2V - 15 = exp(2t + ln(15))

2V - 15 = exp(2t) exp(ln(15))

2V - 15 = 15 exp(2t)

2V = 15 + 15 exp(2t)

V = 15/2 (1 + exp(2t))

(where exp(x) = )

Then the volume of fluid after t = 2 s is

V = 15/2 (1 + exp(4)) ≈ 417 cm³

The population would be the name that is used to refer to the segmentation variables

What is population in research?

In research, population refers to the entire group of individuals or objects that share a common characteristic and are of interest to the researcher. The population is the group to which the researcher wishes to generalize their findings. For example, if a researcher is studying the effects of a new medication on blood pressure in adults, the population would be all adult individuals who have high blood pressure.

It is important to define the population accurately in research because the results of the study can only be generalized to the population being studied. If the population is not defined accurately, the results of the study may not be applicable or generalizable to other groups or populations.

50 Points!!!!!! Triangle ABC is given.

Angle A is labeled two x degrees. Angle B is labeled forty degrees. Angle C is labeled three x degrees.

What is the measure, in degrees, of ∠A?

Enter your answer in the box.

50 Points!!!!!! Triangle ABC is given.Angle A is labeled two x degrees. Angle B is labeled forty degrees.

Answers

All 3 angles add up to 180 degrees.

so 40 + 2x + 3x = 180

40 + 5x = 180

5x = 140

x = 28

So angle A = 2x = 2(28) = 56 degrees.

Answer: 56°

Step-by-step explanation:

We know that a triangle's angles add up to 180 degrees. We will create an equation to help us solve for x using this information.

     Given:

           2x + 3x + 40 = 180

     Combine like terms:

           5x + 40 = 180

     Subtract 40 from both sides of the equation:

           5x = 140

     Divide both sides of the equation by 5:

           x = 28

Next, we will substitute this value of x into the expression for ∠A.

     ∠A = 2x = 2(28) = 56°

The time, t, required to drive a certain distance varies inversely with the speed r. if it takes 7 hours to drive the distance at 55 miles per hour, how long ill it take to drive the same distance at 65 miles per hour, how long will it take to drive the same distance.
A. about 6.25 hours
B. about 385.00 hours
C. about 5.92 hours
D. about 3.21 hours

Answers

Option C. It t will take approximately 5.923 hours to drive the same distance at 65 miles per hour.

How to solve for the time taken

t = k / r

where k is the constant of variation.

First, we need to find the constant of variation, k, using the given information:

t = 7 hours when r = 55 mph

7 = k / 55

To find k, multiply both sides by 55:

k = 7 * 55 = 385

Now that we have the constant of variation, we can find the time it will take to drive the same distance at 65 mph:

t = k / r

t = 385 / 65

t ≈ 5.923 hours

So, it will take approximately 5.923 hours to drive the same distance at 65 miles per hour.

Answers

Solving a system of equations we can see that:

She needs to use 56 oz of the 85% solution.She needs to use 14 oz of the 60% solution.How many ounces of each solution should she use?

We can use the variables:

x = mass of the 60% solution.

y = mass of the 85% solution.

We can write a system of equations.

x + y = 70

x*0.6 + y*0.85 = 70*0.8

We can isolate x on the first equation to get:

x = 70 - y

Replace that in the other one:

(70 - y)*0.6 + y*0.85 = 70*0.8

Now we can solve this for y.

y*0.25 = 70*0.8 - 70*0.6

y = 14/0.25 = 56

Then he needs to use 56 ounces of the 85% solution, and 14 ounces of the 60% solution.

Give your answer to 1 decimal place.

Answers

The percentage population increase from 2001 to 2011 is 50%.

To calculate the percentage population increase from 2001 to 2011, you need the population figures for both years. Let's assume the population in 2001 was 100,000 and in 2011 it was 150,000.

The formula to calculate the percentage increase is:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Plugging in the values:

Percentage Increase = ((150,000 - 100,000) / 100,000) * 100 = (50,000 / 100,000) * 100 = 0.5 * 100 = 50%

Therefore, the percentage population increase from 2001 to 2011 is 50%.

Please note that the actual population figures for the respective years need to be used in the calculation to obtain an accurate result. The example above is for illustrative purposes.

Justin owns a small business selling used books. He knows that in the last week 76 customers paid cash, 4 customers used a debit card, and 42 customers used a credit card. If next week, he is expecting 200 customers, about how many would you expect to pay with cash? Round your answer to the nearest whole number.

Answers

Rounding this to the nearest whole number, we can estimate that about 125 customers will pay with cash next week.

Based on the previous week's data, the percentage of customers who paid with cash is (76/122)*100 = 62.3%. If we assume that this percentage will remain constant for the next week, then we can estimate that out of 200 customers, approximately 62.3% will pay with cash.
To calculate this, we can use the proportion:
(76/122) = (x/200)
where x is the number of customers we expect to pay with cash next week.
Solving for x, we get:
x = (76/122)*200 = 124.59
Rounding this to the nearest whole number, we can estimate that about 125 customers will pay with cash next week.
