Consider the following first order differential equation: y = 3xy - 4 sec(y) (a) (7 points) Find the general solution to the differential equation. (b) (2 points) Find the particular solution when y(2) = 2

Answers

Answer 1

The general solution to the given first-order differential equation is y = ln|x| - 4 sec(y) / 3, where ln|x| represents the natural logarithm of the absolute value of x and particular solution is 2 = ln|2| - 4 sec(2) / 3.

To find the general solution, we start by isolating the variable y on one side of the equation. By rearranging the equation, we get y + 4 sec(y) / 3 = 3xy. Then, we divide both sides by 3x, which yields (y + 4 sec(y) / 3) / (3x) = 1. Finally, by integrating both sides with respect to x, we obtain the general solution: ∫ [(y + 4 sec(y) / 3) / (3x)] dx = ∫ 1 dx. Integrating the left side and simplifying, we arrive at y = ln|x| - 4 sec(y) / 3, as the general solution.

To find the particular solution when y(2) = 2, we substitute the given initial condition into the general solution. Plugging in y = 2 and x = 2, the equation becomes 2 = ln|2| - 4 sec(2) / 3. We can then solve this equation numerically or using numerical methods to find the value of x that satisfies the equation.

Step-by-step explanation:

Hey there!

The area of a shape is the total measurement of the inside of the shape

Meaning the parts I shaded in the screenshot

As you can see in the image, there is less area in shape B than shape A

Meaning, that the area has decreased

Now, Tom says that both area and perimeter has decreased

Lets check if the perimeter has decreased

If you look at it, the perimeter hasn't decreased at all

All that has happened was the shape getting a new form

The dimension are basically split

For example, if the top side of the square was 6 inches

Then the dimension after taking out a square from the shape would split

The top side of that square after is was split would be something along the ligns of 4 inches, and 2 inches and other dimensions like that

That is how I think of the perimeter and if it changes or not

Find the area enclosed by the curve x 3t, y t and the y-axis. Step 1 The curve x = t2-3t, y = Vt intersects the y-axis when x = 0, which occurs when t = 0 and 3 3 H 3 '

Answers

The area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis is 2.08 square units.

We have been given parametric equations x = t^2 − 3t, y = √t

We need to find the area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis.

Consider x = 0

So, t^2 − 3t =  0

t(t - 3) = 0

t = 0   or  t = 3

Let f(t) =  t^2 − 3t and g(t) = t

Differentiate the curve f(t) with respect to t.

f'(t) = 2t - 3

NWe know that the formula to find the area under the curve.

A = ∫[a to b] g(t)f'(t) dt

here, a = 0 and b = 3

so, A = ∫[0 to 3] √t (2t - 3) dt

A = ∫[0 to 3] (2t√t - 3√t) dt

A = ∫[0 to 3] (2t^(3/2) - 3t^(1/2)) dt

A = [4/5 t^(5/2) - 2 t^(3/2)]_[t = 0, t = 3]

A = 4/5 3^(5/2) - 2 3^(3/2) - 0 + 0

A = 4/5 3^(5/2) - 2 3^(3/2)

A = 6√3 /5

A = 2.08

Therefore,  the area of the curve is 2.08 square units.

(c) What is the velocity of each vehicle when they are abreast? 485 A juggler performs in a room whose ceiling is 9ft above the level of his hands. He throws a ball vertically upward so that it just reaches the ceiling. (a) With what initial velocity does he throw the ball? (b) How many seconds are required for the ball to reach the ceiling? He throws a second ball upward, with the same initial velocity, at the instant the first ball touches the ceiling. (c) How long after the second ball is thrown do the two balls pass cach other? (d) When the balls nass, how far are they above the juggiers hands?

Answers

a). Solving for time (t): t = 150 ft / (v_car - v_truck)

b). Distance traveled by the car = v_car * t

c). The velocity of each vehicle when they are abreast is equal to the velocity of the car or the velocity of the truck.

(a) To calculate how long it takes for the car to overtake the truck, we need to consider their relative speeds and the distance traveled by the truck before being overtaken.

Let's assume the car's speed is v_car and the truck's speed is v_truck. Given that the truck has moved 150 ft before being overtaken, we can set up the following equation:

Distance traveled by the car = Distance traveled by the truck + 150 ft

Using the formula distance = speed × time, we can express this equation as:

v_car * t = v_truck * t + 150 ft

Since the car overtakes the truck, its speed is greater than the truck's speed (v_car > v_truck).

Solving for time (t):

t = 150 ft / (v_car - v_truck)

(b) To determine how far the car was initially behind the truck, we can substitute the value of time (t) obtained in part (a) into the equation for distance traveled by the car:

Distance traveled by the car = v_car * t

(c) When the car overtakes the truck and they are abreast, their velocities are the same. Therefore, the velocity of each vehicle when they are abreast is equal to the velocity of the car or the velocity of the truck.

485:

(a) To calculate the initial velocity with which the juggler throws the ball upward, we need to use the kinematic equation for vertical motion. Assuming upward as the positive direction, the equation is given by:

v_f = v_i + (-g) * t

where:

v_f is the final velocity (0 m/s when the ball reaches the ceiling),

v_i is the initial velocity (what we need to find),

g is the acceleration due to gravity (-9.8 m/s^2),

t is the time taken to reach the ceiling.

Since the final velocity is 0 m/s, we can rearrange the equation to solve for v_i:

0 = v_i - 9.8 m/s^2 * t

Since the ball just reaches the ceiling, the displacement is equal to the height of the ceiling (9 ft or approximately 2.7432 m). We can use the kinematic equation:

s = v_i * t + (1/2) * (-g) * t^2

Rearranging this equation to solve for t:

2.7432 m = v_i * t - 4.9 m/s^2 * t^2

(c) To determine how long after the second ball is thrown the two balls pass each other, we need to find the time at which the first ball reaches its maximum height and begins descending. This time is equal to half of the total time it takes for the first ball to reach the ceiling and fall back down.

(d) When the balls pass each other, the second ball is at the same height as the first ball when it was thrown. This height is equal to the height of the ceiling (9 ft or approximately 2.7432 m) above the juggler's hands.

Answers

Implicit solution for the differential equation is  x^7y^6 + x^7y^2 - (1/8)x^8 + C = 0, where C is the arbitrary constant.

The given differential equation is not in a standard form, but we can check if it is exact by verifying if its partial derivatives satisfy the condition ∂M/∂y = ∂N/∂x, where M and N are the coefficients of dx and dy, respectively. In this case, M = 7y^6 + 2x^3y and N = -6xy^3 - x^6.

By computing the partial derivatives, we find ∂M/∂y = 42y^5 + 2x^3 and ∂N/∂x = -6y^3 - 6x^5. Since these derivatives are not equal, the equation is not exact.

To make the equation exact, we can introduce an integrating factor μ. By dividing the equation by μ and comparing the coefficients of dx and dy, we find that μ = 1/(x^7y^5) is an integrating factor.

Multiplying the entire equation by μ, we obtain (7y/x + 2x^2y^(-4)) dx - (6y^(-2) + x^(-7)) dy = 0.

Now, we recognize that this equation is a total derivative. Integrating both sides with respect to x and y, we obtain the implicit solution x^7y^6 + x^7y^2 - (1/8)x^8 + C = 0, where C is the arbitrary constant.

Hence, the solution to the given differential equation, in implicit form, is x^7y^6 + x^7y^2 - (1/8)x^8 + C = 0, where C represents the arbitrary constant.

a book store was selling 7 books for $39.55. online you could buy 3 books for $24.96. which place has a lower unit price

Answers

Answer:

the book store selling 7 books for $39.55 (the book store)

Step-by-step explanation:

we have to calculate what each book costs. to find out what each book costs, we have to use division...

so for the book store:

39.55 / 7 = 5.65       -       this means that each book costs $5.65 by itself

for the online store:

24.96 / 3 = 8.32       -       this means that each book costs $8.32 by itself

now we have to compare the prices... $5.65 costs less than $8.32, so the book store would have a lower unit price.

The given open sentence is 2t - t = 0. We are asked to find the solution set for this equation using the replacement set {1, 2, 3, 4}.

To find the solution set, we substitute each value from the replacement set into the equation and check if it satisfies the equation. Let's go step by step:

1. Substitute 1 for t in the equation:
2(1) - 1 = 2 - 1 = 1. Since 1 is not equal to 0, 1 is not a solution.

2. Substitute 2 for t in the equation:
2(2) - 2 = 4 - 2 = 2. Since 2 is not equal to 0, 2 is not a solution.

3. Substitute 3 for t in the equation:
2(3) - 3 = 6 - 3 = 3. Since 3 is not equal to 0, 3 is not a solution.

4. Substitute 4 for t in the equation:
2(4) - 4 = 8 - 4 = 4. Since 4 is not equal to 0, 4 is not a solution.

After substituting all the values from the replacement set, we see that none of them satisfy the equation 2t - t = 0. Therefore, there is no solution in the replacement set {1, 2, 3, 4}.

Writing the equation of a sine or cosine function given its graph:

Answers

A generic graph would be

\(A\cos \mleft(\frac{2\pi x}{p}+\varphi\mright)+D\)

Where:

A = amplitude

p = period

φ = phase

D = middle line

First let's evaluate the period of the function, see that x = -1/4 we have y = 5, it will have again at x = 3/4.

The period is

\(\begin{gathered} p=\frac{3}{4}+\frac{1}{4} \\ \\ p=\frac{4}{4}=1 \end{gathered}\)

Let's put it in our function already

\(\begin{gathered} A\cos \mleft(\frac{2\pi x}{p}+\varphi\mright)+D \\ \\ A\cos (2\pi x+\varphi)+D \end{gathered}\)

To find out the amplitude, we take the max value, the minimum value (all in modulus) and take the average, the max value here is 5 and the minimum -3 (in modulus it's 3), the average is

\(A=\frac{5+3}{2}=\frac{8}{2}=4\)

Therefore

\(4\cos (2\pi x+\varphi)+D\)

And the D value will be the average too, of the maximum two, but here we don't use the modulus on negative values, therefore

\(D=\frac{5-3}{2}=\frac{2}{2}=1\)

Hence.

\(4\cos (2\pi x+\varphi)+1\)

We know that when x = 0 we have y = 1, then

\(\begin{gathered} y=4\cos (2\pi x+\varphi)+1 \\ \\ 1=4\cos (2\pi\cdot0+\varphi)+1 \\ \\ 4\cos (\varphi)=0 \\ \\ \cos (\varphi)=0 \end{gathered}\)

When cos(φ) = 0? when φ = π/2 for example. Of course, there are other solutions but we just need one. Now we have all the parameters of our cosine

\(4\cos \mleft(2\pi x+\frac{\pi}{2}\mright)+1\)

The final answer is:

\(4\cos \mleft(2\pi x+\frac{\pi}{2}\mright)+1\)

Answers

The inequality that represents all the solutions of -2(3x + 6) ≥ 4(x + 7) is x ≤ -4

How to determine the solution of the inequality?

From the question, we have the following parameters that can be used in our computation:

-2(3x + 6) ≥ 4(x + 7)

Divide both sides of the inequality by -2

So, we have the following representation

3x + 6 ≤ -2(x + 7)

Open the brackets

This gives

3x + 6 ≤ -2x - 14

Add 2x to both sides of the inequality

So, we have the following representations

5x + 6 ≤ -14

Subtract 6 from both sides of the inequality

So, we have the following representations

a fair die is rolled times. what is the probability that a is obtained on at least one of the rolls? round your answer to three decimal places. (if necessary, consult a list of formulas.)

Answers

The probability of obtaining a 1 on at least one roll of a fair die rolled times is 0.421 (rounded to 3 decimal places).

Let E be the event of obtaining a 1 on at least one roll. We can find the probability of E using the complement rule:
P(E) = 1 - P(E')
where E' is the event of not obtaining a 1 on any of the rolls. Since the die is fair, the probability of obtaining any number on any roll is 1/6. Therefore, the probability of not obtaining a 1 on any roll is (5/6) for each roll.Using the multiplication rule for independent events, the probability of not obtaining a 1 on any of the rolls is:
(5/6) x (5/6) x (5/6) x ... x (5/6) (rolled times) = (5/6)^n
Therefore, the probability of obtaining a 1 on at least one roll is: P(E) = 1 - P(E') = 1 - (5/6)^n
We are given that the die is rolled times. Substituting n = into the formula above, we get:
P(E) = 1 - (5/6)^ = 1 - 0.3349 ≈ 0.421
Therefore, the probability of obtaining a 1 on at least one roll of a fair die rolled times is 0.421 (rounded to 3 decimal places).

Answers

Answer:

A) -3/4

B) 15 more minutes

C) 80 minutes

Step-by-step explanation:

A. rate of change = -3/4

B. 16 minutes

C. 1 hour 20 minutes

What is slope?

The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

Given:

A) At first the tank contain 15 gallons of water.

After 4 minutes the tank contain 12 gallons of water.

So, rate of change

=12-15/4-0

=-3/4

=-3/4

B) now, Let x be the number of minutes will it take for the tank to drain completely.

So,

(3/4 gallons per minute) *x = 12 gallons

x = 12*4/3

x = 16 minutes

C) As, the tank has capacity of 75 gallons.

So, the tank of water is full when there is 10 gallons of water which is 60 gallons more.

Let 'y' be the number of minutes before Bob arrived when the water tank was completely full.

(3/4) (y) = 60

y = 60*4/3

y=  80 minutes

y= 1 hour 20 minutes

Answers

The rectangular equation for the path of the projectile launched at height h and angle θ with initial velocity vo is y = 6 + x - 0.008x². To find h, vo, and θ, we can eliminate the parameter t from the parametric equations and solve for the coefficients of the resulting rectangular equation. By comparing the coefficients, we can determine h = 6, vo = √2000, and θ = arctan(√2000).

To eliminate the parameter t from the parametric equations x = tvo cos(θ) and y = h + (vo sin(θ)t - 16t²), we can solve the first equation for t and substitute it into the second equation. This gives us y = h + (x / (vo cos(θ)))tan(θ) - (16 / (vo² cos²(θ)))x². Comparing this equation with the given rectangular equation y = 6 + x - 0.008x², we can determine the values of h, vo, and θ. In this case, h = 6, vo = √2000, and θ = arctan(√2000).

Using a graphing utility, we can plot the rectangular equation y = 6 + x - 0.008x² to visualize the path of the projectile. Additionally, we can sketch the curve represented by the parametric equations x = tvo cos(θ) and y = h + (vo sin(θ)t - 16t²) to confirm that they represent the same path.
