whats the answer for this (-4)+(-4)+(-4)

Answer:

x = 20

Step-by-step explanation:

\(\frac{10}{x}\) = \(\frac{x}{40}\)

We cross-multiply and get

400 = \(x^{2}\)

\(\sqrt{400}\) = \(\sqrt{x^{2} }\)

x = 20

So, the answer is x = 20

Step-by-step explanation:

a. To solve the ODE y" + 4y = 10cos(5t) using Laplace transforms, we follow these steps:

Applying the Laplace transform to the equation, we get:

\(s^2Y(s) - sy(0) - y'(0) + 4Y(s) = 10/(s^2 + 25)\)

Using the initial conditions y(0) = 0 and y'(0) = 0, we simplify the equation to:

\(s^2Y(s) + 4Y(s) = 10/(s^2 + 25)\)

Combining the terms and factoring out Y(s), we have:

\(Y(s) = 10/(s^2 + 25) / (s^2 + 4)\)

We can rewrite Y(s) as:

\(Y(s) = A/(s^2 + 25) + B/(s^2 + 4)\)

Multiplying through by the common denominator\((s^2 + 25)(s^2 + 4)\), we get:

\(10 = A(s^2 + 4) + B(s^2 + 25)\)

Equating coefficients of the like terms, we have:

\(0s^3: 0 = Bs^2: 0 = 4A + 25B\)

0s: 0 = 4B

constant: 10 = 4A

From these equations, we find that A = 10/4 = 5/2 and B = 0

Taking the inverse Laplace transform of Y(s), we obtain the solution in the time domain:

y(t) = (5/2)cos(5t)

Therefore, the solution to the given ODE with the initial conditions is y(t) = (5/2)cos(5t).

b. To solve the ODE y^(4) - y = 0 using Laplace transforms, we follow these steps:

Applying the Laplace transform to the equation, we get:

\(s^4Y(s) - s^3y(0) - s^2y'(0) - sy''(0) - y'''(0) - Y(s) = 0\)

Using the initial conditions y(0) = 0, y'(0) = 1, y''(0) = 0, and y'''(0) = 0, we simplify the equation to:

\(s^4Y(s) - s^2 = s^3\)

Combining like terms and rearranging the equation, we have:

\(s^4Y(s) - Y(s) = s^3 + s^2\)

Factoring out Y(s), we get:

\(Y(s) = (s^3 + s^2) / (s^4 - 1)\)

We can rewrite Y(s) as:

\(Y(s) = (s^3 + s^2) / [(s^2 + 1)(s^2 - 1)]\)

Using partial fraction decomposition, we have:

\(Y(s) = (s + 1) / (s^2 + 1) + (s - 1) / (s^2 - 1)\)

Taking the inverse Laplace transform of Y(s), we obtain the solution in

the time domain:

y(t) = cos(t) + sinh(t)

Therefore, the solution to the given ODE with the initial conditions is y(t) = cos(t) + sinh(t).

The amount of charge on the capacitor after 0.06 seconds = 0.042 millicoulombs

An electric circuit is defined as the device that aids in transmission of electricity generated by a battery or a generator.

Answer:

You followed through on the offer cost of $21.45 per share for your stock, and you can sell it for its net resource estimation of $41.30 per share. That is a benefit of just $19.85 per share, which isn't the $20 per share you need to get.

Step-by-step explanation:

Sorry for the late answer my guy.

Based on the information given, the reason why the shares hasn't been sold is because the profit gotten is only $19.85 and not the $20 per share that the person wants to get.

From the information, it was stated that 100 shares of stock were bought in a fund with a net asset value of $21.30 and an offer price of $21.45.

The offer price of $21.45 per share was paid and it can be sold for a net asset value of $41.30 per share. Therefore, the profit made will be:

= $41.30 - $21.45

= $19.85

A)  Equation to represent perimeter of a square is directly proportional to the length of its sides is P = ks.

B) When we double the length of the side, s becomes 2s, and the perimeter becomes P = k(2s) = 2ks, k remaining constant.

A)  Let's define the perimeter of the square as P, and the length of one side as s. The direct proportionality between them can be expressed as:

P = ks

where k is the constant of proportionality.

B) For example, let's say we have a square with sides of length 4 cm. The perimeter of this square would be,

P = 4 + 4 + 4 + 4 = 16 cm

Now, let's double the length of each side to 8 cm. The perimeter of this new square would be calculated being,

P = 8 + 8 + 8 + 8 = 32 cm

As it can be found that the perimeter has doubled as well. This can be explained using the equation from part A, P = ks

When we double the length of the side, s becomes 2s, and the perimeter becomes:

P = k(2s) = 2ks

The proportionality constant, k, stays the same. Therefore, the perimeter is directly proportional to the length of the sides.

To find the Laplace transform of f(t), we use the formula:

L{f(t)} = ∫[0,∞) \(e^(-st)\) f(t) dt

where L{f(t)} denotes the Laplace transform of f(t) and u(t) is the unit step function.

Using the linearity of the Laplace transform, we can find the Laplace transform of each term separately and add them up.

L{6u(t-2)} = \(6e^(-2s)\) / s (applying the time-shift property)

L{3u(t-5)} = \(3e^(-5s)\) / s (applying the time-shift property)

L{-4u(t-6)} = -\(4e^(-6s\)) / s (applying the time-shift property)

Therefore, the Laplace transform of f(t) is:

F(s) = L{f(t)} = 6\(e^(-2s)\) / s + \(3e^(-5s)\) / s - \(4e^(-6s)\)/ s

= \((6e^(-2s) + 3e^(-5s) - 4e^(-6s)) / s\)

Hence, the Laplace transform of f(t) is F(s) = \((6e^(-2s) + 3e^(-5s) - 4e^(-6s)) / s.\)

x = 6 units

Step-by-step explanation:

For θ = 30°, Perpendicular is 3. Hypotenuse is x.

We can use trigonometry to find x.

\(\sin(30)=\dfrac{P}{H}\)

\(\sin(30)=\dfrac{3}{x}\\\\x=\dfrac{3}{\sin(30)}\\\\x=6\)

So, the value of x is equal to 6 units.

According to the information, the average will not adequately show the growth of the area covered by mold.

To identify how well does the average rate of change describe how the mold changes for these 6 days we must carefully observe the data in the table and draw a conclusion.

As we can see, the value of the area covered by mold doubles every day. From the foregoing, we can infer that an average will not correctly express this change because it expresses a general value over all days that does not reflect growth.

A linear function can be represented by an equation of the form y = mx + b, where m is the slope of the function and b is the y-intercept. The x-intercept is the point where the graph of the function intersects the x-axis, and the y-intercept is the point where the graph intersects the y-axis.

Given that the x-intercept of the linear function is −8 and the y-intercept is 4, an equation of the function can be written as:

y = mx + b

Substituting the values of the x-intercept and the y-intercept into this equation, we get:

y = m(-8) + 4

Since the y-intercept is 4, this equation can be rewritten as:

y = 4 + mx

This equation represents a linear function with a y-intercept of 4 and a slope of m.

Therefore, an equation of the linear function with an x-intercept of −8 and a y-intercept of 4 is y = 4 + mx.

Answer:

D.) 9:1

he original poster has an area of:

Area = length x width = 5 in x 3 in = 15 sq in

When the length and width are tripled, the new poster has a length of 5 in x 3 = 15 in and a width of 3 in x 3 = 9 in. So, the area of the new poster is:

New Area = length x width = 15 in x 9 in = 135 sq in

The ratio of the area of the new poster to the area of the original poster is:

New Area : Original Area = 135 sq in : 15 sq in = 9 : 1

Step-by-step explanation:

The rules for the lines are:

a. y = -4x - 24

c. y = -2x + 4

e. y = 1.5x - 3.75

a. If the gradient is -4 and the x-intercept is -6, the equation of the line can be written in slope-intercept form as:

y = -4x + b

To find the y-intercept (b), we use the x-intercept (-6) and substitute it into the equation:

0 = -4(-6) + b

0 = 24 + b

b = -24

Therefore, the equation of the line is:

y = -4x - 24

b. If the gradient is -2 and the x-intercept is 2, the equation of the line can be written in slope-intercept form as:

y = -2x + b

To find the y-intercept (b), we use the x-intercept (2) and substitute it into the equation:

0 = -2(2) + b

0 = -4 + b

b = 4

Therefore, the equation of the line is:

y = -2x + 4

c. If the gradient is 1.5 and the x-intercept is 2.5, the equation of the line can be written in slope-intercept form as:

y = 1.5x + b

To find the y-intercept (b), we use the x-intercept (2.5) and substitute it into the equation:

0 = 1.5(2.5) + b

0 = 3.75 + b

b = -3.75

Therefore, the equation of the line is:

y = 1.5x - 3.75
