The output of this code will be a signal that starts at zero and gradually increases to three. After five seconds, the signal starts decreasing to zero, with an exponential decay rate. The output plot will look like a ramp that rises linearly and falls exponentially after five seconds.

The term "son of a mention" is not familiar in mathematics. The correct term might be "son of a gun" or "son of a function."A differential equation used to model your specific engineering course is called an engineering differential equation. Such equations are used to predict, control, and monitor various physical processes, ranging from the dynamics of mechanical systems to the motion of fluids and gases, and electrical and electronic circuits. It's essential to know the form of the differential equations, the initial and boundary conditions, and the physical meaning of the parameters to use them effectively in modeling physical systems.

The following MATLAB code represents a simple for loop with a nested if-else statement and a plotting command. The code generates a signal with two segments: a rising ramp from zero to three and a falling ramp from three to zero. The signal has a total duration of 10 seconds, a sampling interval of 0.05 seconds, and a plotting delay of 0.002 seconds.

t = t + 0.05 10 pauses (0.002)

Answer:

(5,21)

Step-by-step explanation:

multiply the second equation by 4

=4x-20y=-400

now subtract the second from first

4x-4x = 0

-y-(-20y) = 19y

-1-(-400) = 399

19y = 399

divide equation by 19

399/19 = 21

y = 21

input 21 into any of the equations

4x-21=-1

4x=20

A sine wave is also known as a sinusoid. The sine function that has an amplitude of 5, a midline of 2 and a period of 3/7​ is 5Sin(16πx/3)+2.

A sine wave, also known as a sinusoid, is the graph of the sine function. Any curve that can be expressed in the form is referred to as a sinusoid. (A and B are both positive.) Sinusoids are the most generic version of the sine function.

Given the amplitude of the function is 5, the vertical shift is 3, and the period of 3/7. Therefore, the values of constants can be written as,

a = 5

b = (2π)/(3/7) = 14π/3

d = 2

Substituting the values in the sine function,

a sin b (x-c) + d

= 5 Sin(16π/3)(x-0) + 2

= 5 Sin(16πx/3) + 2

Hence, the sine function that has an amplitude of 5, a midline of 2 and a period of 3/7​ is 5Sin(16πx/3)+2.

Solution of the expression are,

x = 4 and x = - 4

Given that;

Expression is,

- 2 |x - 2| + 3 = x - 5

Now, We can simplify the expression as;

- 2 |x - 2| + 3 = x - 5

- 2 |x - 2| = x - 5 - 3

- 2 |x - 2| = x - 8

|x - 2| = 4 - x/2

This gives two solutions as;

x - 2 = 4 - x/2

x + x/2 = 6

3x/2 = 6

3x = 12

x = 4

And, x - 2 = - (4 - x/2)

x - 2 = - 4 + x/2

x - x/2 = - 4 + 2

x/2 = - 2

x = - 4

Thus, Solution of the expression are,

The rate of change of a circle diameter with respect to radius is 0.

The rate of change of a circle diameter with respect to radius (D2(r)) can be calculated by using the formula dD2/dr. This formula states that the rate of change of a function at a given point is equal to the derivative of the function at that point.

To calculate the rate of change of a circle diameter with respect to radius, we must first calculate the derivative of the circle diameter with respect to radius. The formula for diameter of a circle is D = 2r, where r is the radius of the circle. Taking the derivative of the equation with respect to r gives us dD/dr = 2. This means that the rate of change of a circle diameter with respect to radius is 2.

We can also calculate the rate of change of a circle diameter with respect to radius using the formula dD2/dr. This formula states that the rate of change of a function at a given point is equal to the second derivative of the function at that point. Taking the second derivative of the equation for the diameter of a circle with respect to radius gives us d2D/dr2 = 0. This means that the rate of change of a circle diameter with respect to radius is 0.

Therefore, the rate of change of a circle diameter with respect to radius is 0.

The probability of the experiment ends after exactly six flips of the coin with a head on the fifth toss as well as on the sixth is 3/8.

Let's say that the probability of getting a head in a single coin toss is p = 0.5.

Here, we have to calculate the probability of getting a head in both the fifth and the sixth toss when the experiment ends after exactly six flips of the coin after three heads have occurred.

Let's say that X is the number of coin tosses that are needed to get three heads.

So, X can be 3, 4, 5, 6, and so on.

If the experiment ends on the 6th flip, then the first three tosses must result in heads, and the next two must be tails, and the sixth toss must be a head.

The probability that the experiment ends after exactly six flips of the coin with a head on the fifth toss as well as on the sixth is  3/8.

Explanation:

Given that an experiment consists of tossing a fair coin until three heads occur.

Therefore,

p(head) = p = 1/2 and

p(tail) = q = 1 - p = 1/2.

Let X be the number of coin tosses required to get three heads.

If X=6, then the sequence of the toss must be H, H, H, T, T, H.

So, the probability of this sequence is (1/2)3(1/2)2(1/2)

= 1/48.

Therefore, the probability of ending the experiment after exactly six flips of the coin with a head on the fifth toss as well as on the sixth is:

P(getting H on 5th and 6th toss) = 1/48/P(X=6)

As there are many ways of getting 3 heads in X tosses, we should compute the probability of all these ways and sum them up to get P(X=6).

The possible ways are:

H, H, H, T, T, H or

H, H, T, H, T, H or

H, T, H, H, T, H or

T, H, H, H, T, H or

T, H, T, H, H, H or

T, T, H, H, H, H.

So,

P(X=6) = 6(1/2)3(1/2)2(1/2) + 6(1/2)2(1/2)3(1/2)2 + 6(1/2)2(1/2)2(1/2)3 + (1/2)3(1/2)3(1/2) + 6(1/2)2(1/2)3(1/2)2 + (1/2)3(1/2)2(1/2)3

= 7/16

Hence, P(getting H on 5th and 6th toss) = 1/48 × 16/7 = 3/8.

Therefore, the probability of the experiment ends after exactly six flips of the coin with a head on the fifth toss as well as on the sixth is 3/8.

Step-by-step explanation:

Katie outscored approximately 1.39% of the students in her section.

If Katie received a z-score of 2.2, this means that her score was 2.2 standard deviations above the mean of the exam scores for her section.

We can use a standard normal distribution table or calculator to find the percentage of scores that fall above a z-score of 2.2.

Using a standard normal distribution table, we can find the proportion of scores that fall below a z-score of 2.2, and then subtract this from 1 to find the proportion of scores that fall above a z-score of 2.2.

The table value for a z-score of 2.2 is approximately 0.9861, which means that approximately 98.61% of the scores fall below a z-score of 2.2. Therefore, approximately:

1 - 0.9861 = 0.0139, or 1.39%

of the scores fall above a z-score of 2.2.

This means that Katie outscored approximately 1.39% of the students in her section.

Given the the following equations, find the unknown value, ?, that makes the equations true

.\(? - 4 - 2p + 5 = 6p + 17d - 4 + 3 - 2d = ? - 112c - 8 - 2c + 10 - 4 = 10c -?\)

Starting with the equation, \(? - 4 - 2p + 5 = 6p + 1\)

Start with the side that is more complex, \(?-4-2p+5\). Simplify it as best you can by combining all like terms.

\(?-4-2p+5\)

=>\((?)+(-2p)+(-4+5)\)

=> \(?-2p+1\)

Now look at the R.H.S (\(6p+1\)), notice how we have the +1 in the simplified expression above. So what value would we put in for "?" to get 6p? That value would be 8p.

Now we have, \((8p)-2p+1=6p+1\)

Let x represent the number of session

Since One tennis club charges $ 34 per session to play tennis. We can write the cost as:

cost = 34x

And another tennis club charges an annual fee of $ plus $ 22 per session. We can write the cost as:

cost = 48 + 22x

At the same cost, we have:

34x = 48 + 22x

34x - 22x = 48

The payback period of the project is 2 years.

The payback period is a financial metric used to evaluate the time it takes for an investment to recoup its initial cost. It measures the length of time required for the cash inflows from the investment to equal or surpass the initial investment amount. In this case, the initial investment is $35,000, and the cash flows are $10,000 in year 1, $20,000 in year 2, and $10,000 in year 3. To calculate the payback period, we need to determine in which year the cumulative cash inflows will equal or exceed the initial investment.

By adding the cash flows year by year, we can see that at the end of year 1, the cumulative cash inflow is $10,000. By the end of year 2, the cumulative cash inflow becomes $30,000 ($10,000 from year 1 + $20,000 from year 2). Finally, at the end of year 3, the cumulative cash inflow reaches $40,000 ($10,000 from year 3).
