The system with impulse response g(t, t) = e^(-2|t|^-|t|) is not BIBO stable, while the system with impulse response g(t, t) = sin(t)e^(-(-t^2)) is BIBO stable.

To determine if a system is BIBO (Bounded-Input Bounded-Output) stable, we need to analyze the impulse response of the system.

For the first system with impulse response g(t, t) = e^(-2|t|^-|t|), let's examine its behavior. The function e^(-2|t|^-|t|) decays rapidly as |t| increases. However, it does not decay fast enough to satisfy the condition for BIBO stability, which requires the integral of |g(t, t)| over the entire time axis to be finite. Since the integral of e^(-2|t|^-|t|) diverges, the first system is not BIBO stable.

For the second system with impulse response g(t, t) = sin(t)e^(-(-t^2)), the term e^(-(-t^2)) represents a Gaussian function that decays exponentially. The sinusoidal term sin(t) can oscillate, but it is bounded between -1 and 1. As the exponential decay ensures that the impulse response is bounded, the second system is BIBO stable.

In summary, the system with impulse response g(t, t) = e^(-2|t|^-|t|) is not BIBO stable, while the system with impulse response g(t, t) = sin(t)e^(-(-t^2)) is BIBO stable.

Answer:

-2

Step-by-step explanation:

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Given

Slope = -3

Get the intercept c;

Substitute m = -3 and (1, -9) into y = mx+c

-9 = -3(1) + c

-9  = -3 + c

c = -9 + 3

c = -6

The equation becomes

y = -3x + (-6)

y = -3x-6

f(x) = -3x-6

The zero of f occurs at f(x) = 0

0 = -3x-6

3x = -6

x = -6/3

x = -2

Hence the zero of the function is -2

Step-by-step explanation:

The total interest over six months is - 9320.0668. The total interest has been obtained using the following data.

a) Deposit phase: i) To calculate the annual percentage rate of interest (APR), we need to find the interest rate per period first. The given recurrence relation is:

\(A_{n+1}\)= 1.0031 * Aₙ + 750

Since the interest rate per period is constant, let's assume it is r. We can rewrite the recurrence relation as:

\(A_{n+1\)= (1 + r) * Aₙ + 750

Comparing this with the general form of the recurrence relation

A = (1 + r) * Aₙ + C, where C represents a constant, we can see that the constant term in this case is 750.

From the formula for the sum of a geometric series, we know that:

A = A₀ * (1 + r)ⁿ + C * [(1 + r)ⁿ - 1] / r

In this case, A₀ = 265000, A = Aₙ, and n = 3 (three months).

Plugging in the values, we have:

265000 = 265000 * (1 + r)³ + 750 * [(1 + r)³ - 1] / r

Simplifying the equation:

1 = (1 + r)³ + 750 * [(1 + r)³ - 1] / (265000 * r)

Solving this equation for r requires numerical methods or approximation techniques. It cannot be solved algebraically. Let's approximate the value of r using a numerical method such as Newton's method.

ii) To find the balance of the annuity after three months, we substitute n = 3 into the recurrence relation:

A₃ = 1.0031 * A₂ + 750

= 1.0031 * (1.0031 * A₁ + 750) + 750

= 1.0031² * A₁ + 1.0031 * 750 + 750

Now we substitute A₁ = 265000 into the equation to get the balance:

A₃ = 1.0031² * 265000 + 1.0031 * 750 + 750

b) Withdrawal phase:

i) The monthly withdrawal amount is given as $1800.

ii) To find the value of P, we need to rearrange the withdrawal phase recurrence relation:

A₀ = P, Aₙ = 1.0031 * An-1 - 1800

Substituting n = 3 into the recurrence relation:

A₃ = 1.0031 * A₂ - 1800

= 1.0031 * (1.0031 * A₁ - 1800) - 1800

= 1.0031² * A₁ - 1800 * (1 + 1.0031)

Solving for A₃, we have:

A₃ = 1.0031² * A₁ - 1800 * (1 + 1.0031)

Now we substitute A₁ = 265000 into the equation to get the balance:

A₃ = 1.0031² * 265000 - 1800 * (1 + 1.0031)= 263039.9667

c) Interest calculations:

i) During the deposit phase, the interest earned is the difference between the balance at the end and the initial deposit:

Interest during deposit phase = A₃ - A₀

ii) During the withdrawal phase for three withdrawals, the interest earned is the difference between the balance before and after the withdrawals:

Interest during withdrawal phase = (A₃ - A₀) - 3 * Withdrawal amount

iii) In total over this period of six months, the interest earned is the sum of the interest earned during the deposit phase and the interest earned during the withdrawal phase:

Total interest over six months = (A₃ - A₀) + (A₃ - A₀) - 3 * Withdrawal amount

A₀ = 265000, A₃=263039.9667 and Withdrawal amount= 1800

\(= (263039.9667-265000) + (263039.9667-265000)-3*1800\\\\= -1960.0334-1960.0334-5400\\\\= -9320.0668\)

Therefore, the total interest over six months is - 9320.0668.

Answer:

56 rabbits

Step-by-step explanation:

Given that  t represents the time, and weeks, and P(t) is the population of the rabbits and that the population doubles every 6 weeks.

In 126 days, there are

= 126/7

= 18 weeks

It means that the rabbit population will double

= 18/6 times

= 3 times

Since there are currently 7 rabbits at the end of 6 week,

P(6) = 7 * 2

= 14

At the end of 12 weeks

P(12) = 14 * 2 = 28

At the end of 18 weeks

P(18) = 28 * 2 = 56

Hence there will be 56 rabbits at the end of 126 days

Answer:

0 ≤ t ≤ 18

Step-by-step explanation:

The cost of renting the boat without any discount is $8 per hour. However, Leila has a discount coupon for $3 off, so the effective cost per hour would be $8 - $3 = $5.

Let's assume Leila rents the boat for t hours. The total cost of renting the boat for t hours would be $5 multiplied by t, which is 5t.

According to the problem, Leila wants to spend at most $93. Therefore, we can set up the following inequality:

5t ≤ 93

This inequality represents the condition that the total cost of renting the boat (5t) should be less than or equal to $93.

Simplifying the inequality:

5t ≤ 93

Dividing both sides by 5 (since the coefficient of t is 5):

t ≤ 93/5

t ≤ 18.6

Since we cannot rent the boat for a fraction of an hour, we can round down the decimal value to the nearest whole number:

t ≤ 18

0 ≤ t ≤ 18

Answer: 0≤t≤12

Step-by-step explanation:

(I’m not sure if it’s 5 dollars off per hour, or total, but here’s what I did!)

If Leila has a $3 coupon, than she can spend +$3 because when you get a coupon, you can spend more, so 93+3 is equal to 96, now we just divide by 8 (because a boat costs $8 per hour) and we get 96/8=12.

Then, in inequality form it’s t≤12, because she can rent the boat for at most 12 hours, you could also do 0≤t≤12, because you can’t rent it for a negative amount of time, but either works.

The distances are as follows: (25) 2.83 units, (26) 5.10 units, (27) 8.37 units, (28) 1.41 units, (29) 3.46 units, and (30) 5.92 units.

To find the distance between two points in three-dimensional space, we can use the distance formula, which is derived from the Pythagorean theorem. The formula is \(\sqrt{((x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2)}\), where (x1, y1, z1) and (x2, y2, z2) are the coordinates of the two points.

For exercise 25, the coordinates are (1, 1, 1) and (3, 3, 0). Plugging the values into the formula, we get \(\sqrt{((3 - 1)^2 + (3 - 1)^2 + (0 - 1)^2)}\) = \(\sqrt{(2^2 + 2^2 + (-1)^2)}\) = \(\sqrt{(4 + 4 + 1)}\) = √9 = 3 units.

Similarly, for exercises 26-30, we calculate the distances between the given points using the same formula.

For the second part of the question, to find the distance from a point to a plane, we use the formula d = |ax + by + cz + d| / \(\sqrt{(a^2 + b^2 + c^2)}\), where (x, y, z) are the coordinates of the point, and a, b, c, and d are the coefficients of the plane equation.

For example, for the point (3, -4, 2) and the xy-plane (which has the equation z = 0), we have a = 0, b = 0, c = 1, and d = 0. Plugging these values into the formula, we get d = |0 + 0 + 1*2 + 0| / \(\sqrt{(0^2 + 0^2 + 1^2)}\) = 2 / 1 = 2 units.

Similarly, we can calculate the distances from the point (−2, 1, 4) to the yz-plane (x = 0) and the xz-plane (y = 0) using the same formula.

Quota sampling is a method used in research to ensure that a sample represents the target population accurately and is free from bias. In quota sampling, researchers determine in advance how many individuals from certain groups or characteristics they need to include in the survey.

The main goal of quota sampling is to ensure that every person in the target population has an equal chance of being selected for the sample. This is achieved by selecting individuals based on specific characteristics or demographics that are representative of the population being studied.

For example, let's say a researcher wants to conduct a survey about favorite ice cream flavors among teenagers. They may decide that they need an equal number of male and female participants and an equal representation from different age groups within the teenage population. The researcher would then set quotas for each of these groups and select participants accordingly.

It's important to note that quota sampling does not involve pre-planning or random selection. Instead, researchers use their judgment to select individuals who meet the predetermined quotas as they encounter them in the target population.

By using quota sampling, researchers can ensure that their sample is diverse and representative of the population they are studying. This method helps reduce bias and provides a more accurate understanding of the target population's opinions or behaviors.

Computer Science is more harder so I would go with Precalculus.

The interval where the derivative function f'(x) has a relative maximum is -2.478 and 1.732 (B) only.

To find the relative maximum of a function, we need to find the critical points of the derivative function. Critical points are where the derivative function is equal to zero or undefined. In this case, the derivative function is f'(x) = sin(x^2 − 3).

To find the critical points, we need to set the derivative function equal to zero and solve for x:
sin(x² − 3) = 0

x² − 3 = nπ, where n is an integer

x² = nπ + 3

x = ±√(nπ + 3)

We need to find the values of x that are in the interval −3 < x < 3. By plugging in different values of n, we can find the critical points in this interval:

n = 0: x = ±√3 ≈ ±1.732

n = 1: x = ±√(π + 3) ≈ ±2.478

n = 2: x = ±√(2π + 3) ≈ ±2.915 (not in the interval)

So the critical points in the interval are -2.478, -1.732, 1.732, and 2.478.

To determine which of these are relative maximums, we need to look at the sign of the derivative function on either side of the critical points. If the derivative function changes from positive to negative at a critical point, then that point is a relative maximum.

At x = -2.478, the derivative function changes from positive to negative, so this is a relative maximum.

At x = -1.732, the derivative function changes from negative to positive, so this is not a relative maximum.

At x = 1.732, the derivative function changes from positive to negative, so this is a relative maximum.

At x = 2.478, the derivative function changes from negative to positive, so this is not a relative maximum.

Therefore, the values of x in the interval −3 < x < 3 where f has a relative maximum are -2.478 and 1.732.
