solve the sum-of-forces equation just derived, 0=∑ify,i=pa−(p dp)a−rhoagdy , to obtain an expression for dp and thus a differential equation for pressure.

Answers

Answer 1

The pressure gradient is a function of the pressure itself, the local acceleration due to gravity, and the density of the fluid.

The sum-of-forces equation is 0=∑ify,i=pa−(p dp)a−ρagdy. Rearranging the equation to isolate dp yields the following expression:

dp = (pa - ρagdy) / p

Differentiating both sides with respect to y yields the differential equation for pressure:

dp/dy = (a(pa - ρagdy) - (dp)(pa)) / p

This equation can be further simplified using the product rule to yield:

dp/dy = pa2/p2 - ρag/p.

This differential equation shows that the pressure gradient is a function of the pressure itself, the local acceleration due to gravity, and the density of the fluid.

The graph of y=16x2 is a parabola that is symmetric about the y-axis and opens upwards. Its vertex is at (0,0) and its intercepts are at (0,0) and (±√16,0). As x increases, the graph increases at a faster rate.

The graph of y=16x2 is a parabola that is symmetric about the y-axis and opens upwards. The vertex of the parabola is the point (0,0), which is the point where the parabola changes direction. The y-intercept of the graph is the point (0,0) and the x-intercepts are the points (±√16,0). This means that the graph crosses the x-axis at x=±√16.  As x increases, the graph increases at a faster rate. This is because the exponent of x is 2, meaning that the graph is a quadratic equation. When x=0, the graph is at 0, and as x gets larger, the graph increases more quickly. The graph reaches its maximum at x=√16, where y=16. From this point, the graph decreases until it reaches 0 again at x=-√16.

Show your work.


Question 26

Answers

The solution to the inequality in question is less than or equal to 4300 pounds and 2.6875 cubic yards of sand can be hauled in the truck to still classify as a passenger vehicle.

From the question itself, we can deduce that the inequality is -

Let us assume that the amount of stuff carried by the vehicle is = x

So, the inequality becomes -

= 4200 + x ≤ 8500 pounds

So, if we solve this we will find that the weight of stuff to be carried is going to be -

= x ≤ 8500 - 4200

= x ≤  4300

It should be no more than 4300 pounds.

We can still classify it as a passenger vehicle by carrying only 1.4655 pounds of sand because -

= 2.6875 *1600 = 4300 pounds

This means that by carrying 2.6875 pounds we maintain the rules to remain a passenger vehicle.

PART A
Given this information, fill out the normal distribution chart below for the weight of 9oz bags of chips from this factory.

Answers

The normal distribution chart below for the weights of the factory are 9.02, 9.07, 9.12, 9.17, 9.22 from left to right.

What is standard deviation?

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability. When data points are closely spaced from the mean, there is a small variation, and when they are far spaced from the mean, there is a large variation. The standard deviation determines how much the values deviate from the mean. The most popular way to assess dispersion is standard deviation, which is based on all values.

From the given samples of 9oz of chips we have the following values:

Mean = 9.12 ounces

SD = 0.05 ounces

The normal distribution of the chart below will have the following values:

The mean or the center value of the graph with the highest peak is:

Mean = 9.12

The value to the right of the mean value will be:

Mean + SD = 9.12 + 0.05 = 9.17

Mean + 2(SD) = 9.12 + 2(0.05) = 9.22

Similarly, the value to the left of the mean value will be:

Mean - SD = 9.12 - 0.05 = 9.07

Mean - 2(SD) = 9.12 - 2(SD) = 9.02

Hence, the normal distribution chart below for the weights of the factory are 9.02, 9.07, 9.12, 9.17, 9.22 from left to right.

What is area of a triangle?

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.

A right angled triangle is a triangle with 90°. Since of one of the angle is 45° , this means that the triangle is isosceles and the other two sides will be equal. This means a= b

An ideal gas is a hypothetical gas which follows the ideal gas laws. These laws state that the pressure, volume, and temperature of an ideal gas are related to each other in a predictable and measurable way. In this case, the cylinder has a fixed length and diameter, and the piston is held in place. This means that the volume of the cylinder is fixed and cannot change, even if heat is added to the gas.

How many days will it take for 125 people to contract the virus?

This question uses the theory of exponential growth and decay.

The equation y=500/1990e^-. 5(t) models the spread of a flu virus through a population, where y is the total number of people infected after t days.

The equation follows an exponential decay curve, where the number of people infected decreases with each passing day. In this case, the rate of decay is -.005.

given below

Step 1: Rearrange the equation to isolate t.

y = 500/1990e^-.005(t)

500/y = 1990e^-.005(t)

500/y = e^-.005(t)

ln(500/y) = -.005(t)

Step 2: Substitute the given values of y (125) and solve for t.

iii) train

Since each choice have an equal chance of being chosen,

The probability of Choosing a bus will be 1/3

The probability of Choosing a cab will be 1/3

The probability of Choosing a train will be 1/3

Now, the Probability of Not Choosing the cab will be the sum of the probabilities of choosing a bus and train i.e, 2/3

Now there will be two possibilities-Either She chooses a cab in the morning and something else in the evening Or She chooses a cab in the evening and something else in the morning.

Therefore, the probability of choosing a cab exactly one time =

( Probability of cab in morning x Probability of no cab in the evening) + (Probability of no cab in morning x Probability of cab in evening)
Probability of choosing a cab exactly once

= 1/3 x 2/3  + 2/3 x 1/3

= 4/9

Therefore, the probability that she will choose to use a cab exactly one time is 4/9.

Step-by-step explanation:

the size of a bacteria population grows at a rate of p(t) where t is measured in weeks

Answers

The bacteria will reach its maximum size at t = 8.94 weeks.

To find when the bacteria will reach its maximum size, we need to find the maximum value of p(t). The first step is to find the derivative of p(t):

dp(t)/dt = -8000(t^2 - 80)/(80 + t^2)^2

Next, we need to find the critical points of this derivative by setting it equal to 0 and solving for t:

dp(t)/dt = 0

-8000(t^2 - 80)/(80 + t^2)^2 = 0

t^2 - 80 = 0

t = √80

t = 4√5

t ≈ 8.94

Since t = 4√5 is the only critical point, we can see that it is a local maximum. To confirm this, we need to find the second derivative and evaluate it at t = 0:

d^2p(t)/dt^2 = 16000t (t^2 - 240) / (80 + t^2)^3

d^2p(t)/dt^2 = 160000 * -160 / (80 + 80)^3 < 0

Since the second derivative at t =  4√5 is less than 0, it is a local maximum.

A customer at a shipping store is planning to send a package and is considering two options. The customer can send a package for $5, plus an additional $2 per pound. The cost, y, can be represented by the equation y = 5 + 2x, where x represents the amount of pounds of the package. Another option is that the customer can pay a one-time fee of $15 to send the box, represented by the equation y = 15.

Based on the graph of the system of equations, when will the cost of the two shipping options be the same?

A package that weighs 15 pounds will cost $35 for both options.
A package that weighs 15 pounds will cost $25 for both options.
A package that weighs 10 pounds will cost $15 for both options.
A package that weighs 5 pounds will cost $15 for both options.

Answers

Answer:

A package that weighs 5 pounds will cost $15 for both options.

Step-by-step explanation:

The equation for the cost of the first shipping option is y = 5 + 2x, where x represents the amount of pounds of the package. The cost, y, increases by $2 per pound of the package. So, if the package weighs 5 pounds, the cost of the first option would be y = 5 + 2 * 5 = $15.

The equation for the second shipping option is y = 15, representing a one-time fee of $15 to send the box. The cost is fixed at $15 regardless of the weight of the package.

Therefore, if the package weighs 5 pounds, the cost of both shipping options would be $15, and the two options would cost the same.
