Nonperiodic waveforms. Jump to level 1 \[ v(t)=2 u(t-1)-3 u(t+5) \] At time \( t=-1, v(t)= \)
Answers
Therefore, the value of v(t) at time t = -1 is -3. The function v(t) is a nonperiodic waveform, which means that it does not repeat itself after a certain period of time.
The function is defined as follows:
v(t) = 2 u(t - 1) - 3 u(t + 5)
where u(t) is the unit step function. The unit step function is a function that is equal to 1 for all values of t greater than or equal to 0, and 0 for all values of t less than 0.
To find the value of v(t) at time t = -1, we simply substitute -1 into the function. This gives us:
v(-1) = 2 u(-1 - 1) - 3 u(-1 + 5)
The first unit step function evaluates to 0, because -2 < 0. The second unit step function evaluates to 1, because 4 > 0.
Therefore, the value of v(-1) is equal to:
v(-1) = 2 * 0 - 3 * 1 = -3
Therefore, the value of v(t) at time t = -1 is -3.

Find the value of the inverse function f(x) = x^5 + x + 9 at a point. (Use symbolic notation and fractions where needed.)f^-1 (1037) = _______
Answers
the value of the inverse function f(x) = x^5 + x + 9 at a point 1037 is f^-1 (1037) = 2.22560245.
The inverse of the function f(x) = x^5 + x + 9 is given by f^-1 (x) = x^5 + x + 9.
To find the value of f^-1 (1037) we can apply the inverse of f(x) to 1037.
The inverse of f(x) is f^-1 (x) = x^(1/5) – (x^2 – 9)^(1/2)/5.
Substituting 1037 for x,
we get f^-1 (1037) = 1037^(1/5) – (1037^2 – 9)^(1/2)/5
= 2.2471254 - 0.17152295/5 = 2.22560245.
Therefore, the value of the inverse function f(x) = x^5 + x + 9 at a point 1037 is f^-1 (1037) = 2.22560245.

The price we have to pay for the disc after 10% discount is 1467 dollars.
What is percentage ?Percentage is the value per hundredth.
According to the given question we bought a disc which costs 1630 dollars there's a 10% discount we have to find how much i have to pay.
10% of 1630 dollars will be
= (10/100) × 1630 dollars.
= 16300/100 dollars.
= 163 dollars.

Answers
Alice paid $25 for her pair of jeans, and Jeff paid $4 for the steaks.
Let's calculate the final amount paid by Alice and Jeff for their purchases.
Alice:
Alice has a budget of $30 for a pair of jeans, and a coupon for $10 off.The price of the jeans she selects is $35 before the coupon.To find the final price she paid, we need to subtract the coupon discount from the original price of the jeans: $35 - $10 = $25.So Alice paid $25 for her pair of jeans.Jeff:
Jeff finds a pack of steaks for $16 and is willing to pay up to $20.This means he has a surplus of $20 - $16 = $4 that he is willing to spend on the steaks.The butcher notices the meat is near the expiration date and gives Jeff an extra 75% off.To calculate the discount, we first need to find 75% of the original price: 0.75 * $16 = $12.So Jeff gets a discount of $12, and the final price he paid is the original price minus the discount: $16 - $12 = $4.Therefore, Jeff paid $4 for the steaks.So, Alice paid $25 for her pair of jeans, and Jeff paid $4 for the steaks.

if f(x) is symmetric on (a,b), could you write down an equation
for it. (hint. you can try with y=1/x−a + b)
Answers
If f(x) is symmetric on the interval (a, b), we can write an equation for it using a transformation of the function y = 1/x.
To achieve symmetry on the interval (a, b), we need to shift the graph horizontally by (a + b)/2 units. This will ensure that the function is symmetric about the line x = (a + b)/2.
The equation for the symmetric function can be written as:
y = 1/(x - (a + b)/2)
This equation represents a transformation of y = 1/x where the graph is shifted horizontally to achieve symmetry on the interval (a, b).

The probability of winning a certain game is 0. 5. If at least 70 percent of the games in a series of n games are won, the player wins a prize. If the possible choices for n are n=10, n=20, and n=100, which value of n should the player choose in order to maximize the probability of winning a prize?.

What is the binomial theorem on probability?The probability of precisely x successes on n further trials in an experiment with two potential outcomes is referred to as the binomial probability (commonly called a binomial experiment).
When a procedure is performed a certain number of times (for example, in a group of patients), the result for each patient can either be a success or a failure, the binomial distribution model enables us to calculate the probability of witnessing a defined number of "successes."
The probability of winning a prize remains the same for. n = 10 or n=20 or n = 100; the probabilities are the same.
Given that,
p = 0.5, So, q = 1 - 0.5 = 0.5.
If 70% of 'n' games are won then 30% of n games must be lost.
Let n = 10.
Therefore, P ( x = 3) = \(^{10}C_3p^7q^3\)
or, P ( x = 3) = \(^{10}C_3(0.5)^7(0.5)^3\)
or, P (x = 3) = 120×0.0078×0.125.
or, P (x = 3) = 0.117 Or 11.7% chance.
Now, Changing the value won't have any effect as all the 'n's are multiple of 10 and we'll have same probability.

Each one of the ten people has to shake hands with all the $20$ other people they don’t know. So $10\cdot20 = 200$. From there, we calculate how many handshakes occurred between the people who don’t know each other. This is simply counting how many ways to choose two people to shake hands from $10$, or $\binom{10}{2} = 45$. Thus the answer is $200 + 45 = \boxed{\textbf{(B)}\ 245}$.

The respiratory system takes in oxygen from the air, and also gets rid of carbon dioxide. The digestive system absorbs water and nutrients from the food we consume.
How does the respiratory system and the digestive system work together?The respiratory system is mainly used to transport air, whilst the digestive system is used to transport fluids and solids, from water and food we eat. The respiratory and the digestive systems share the area of the mouth and upper throat, in which air, fluids, and solids can be mixed.

Given: x varies jointly with w and y. If x= 20 when w=

15
and y = 10, what is the value
Answers
The value x, in the joint variation, when w = 8 and y = 3/15, is calculated as: x = 8.
How to Solve a Joint Variation Problem?The formula for joint variation if x varies jointly with w and y, is:
x = kwy, where k is the constant of variation.
To solve for k, we can use the initial condition where x = 20 when w = 2/5 and y = 10:
20 = k(2/5)(10)
Simplifying, we get:
20 = 4k
Divide both sides by 4:
20/4 = 4k/4
k = 5
Now that we know k, we can use it to solve for x when w = 8 and y = 3/15:
x = (5)(8)(3/15)
Simplifying, we get:
x = 8
Therefore, when w = 8 and y = 3/15, the value of x is 8.
