why is the domain of sin^-1(x) and cos^-1(x) are different while the domain of sin(x) and cos(x) are the same?
Answers
The domain of sin^-1(x) and cos^-1(x) are different while the domain of sin(x) and cos(x) are the same is due to the inverse properties and the range of their respective functions.
The domain of sin(x) and cos(x) are the same because both are trigonometric functions that can accept any real number as input, meaning their domain is all real numbers (-∞, ∞).However, when we consider their inverse functions, sin^-1(x) and cos^-1(x), we need to restrict their domain to ensure that these inverse functions are well-defined and unique. The range of sin(x) is between -1 and 1, so the domain of sin^-1(x) is restricted to the interval [-1, 1]. Similarly, the range of cos(x) is also between -1 and 1, but its behavior is different from sin(x), so the domain of cos^-1(x) is also restricted to the interval [-1, 1].In conclusion, while sin(x) and cos(x) share the same domain, their inverse functions, sin^-1(x) and cos^-1(x), have different domains due to the need to restrict their inputs to ensure unique and well-defined inverse functions.

1. For the plot shown, (a) Over the time range shown, is this signal continuous or discrete? (b) Is this a causal signal? Explain. Neatly sketch the following: (c) \( y(t)=x(t-2) \) (d) \( y(t)=x(t+1)
Answers
The signal in the plot is a continuous signal. It is a causal signal, because the output value at any time t only depends on the input values up to time t. The shifted signals y(t) = x(t-2) and y(t) = x(t+1) are also continuous signals.
A continuous signal is a signal that can be represented by a function that is continuous at all points in time. A causal signal is a signal whose output value at any time t only depends on the input values up to time t.
The signal in the plot is a continuous signal because the graph of the signal is a smooth curve. The signal is also a causal signal because the output values of the signal at time t do not depend on the input values at time t+1 or later.
The shifted signals y(t) = x(t-2) and y(t) = x(t+1) are also continuous signals because they are simply shifted versions of the original signal. The graph of y(t) = x(t-2) is the graph of the original signal shifted two units to the right. The graph of y(t) = x(t+1) is the graph of the original signal shifted one unit to the left.

a graduate class has 7 students with a grades and 14 students with b grades. calculate the number of ways in which 4 a students can be uniquely selected.
Answers
There are 35 unique ways to select 4 A students from 7 A students. This can be calculated using the formula: 7C4 = 7! / (4! * (7 - 4)!)
This is a permutation and combination problem that involves finding the number of unique arrangements possible for 4 students out of 7 students who have received grades A.
The formula for permutation of n items taken r at a time is given by P(n,r) = n! / (n-r)! where n is the total number of items and r is the number of items taken at a time.
In this case, we have to find P(7,4) = 7! / (7-4)! = 5040/3! = 840. This means there are 840 different ways in which 4 A students can be uniquely selected from a class of 7 students who received grades A.
This concept is important in many areas of mathematics and science, particularly in the field of statistics where it is used in hypothesis testing, estimation and prediction.

Answers
Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls

Certify Completion Icon Tries remaining: 3 A high school has 52 players on the football team. The summary of the players' weights is given in the box plot. The median weight of the players on the football team is 160 pounds.
The box plot shows that the median weight of the players is the middle value of the distribution. In this case, the median weight is halfway between the 26th and 27th players, which is 160 pounds.
The box plot also shows that the minimum weight of the players is 150 pounds and the maximum weight is 212 pounds. The interquartile range, which is the range of the middle 50% of the data, is 20 pounds.
In conclusion, the median weight of the players on the football team is 160 pounds. This means that half of the players on the team weigh more than 160 pounds and half of the players weigh less than 160 pounds.

a poster of area 11760 cm2 has blank margins of 10 cm wide on the top and bottom and 6 cm wide on the sides. find the dimensions that maximize the printed area.
Answers
A poster of area 11760 cm2 has blank margins of 10 cm wide on the top and bottom and 6 cm wide on the sides. The dimensions that maximize the printed area are 500 cm x 23.52 cm.
The problem can be solved using the following concept:
Suppose we have a function f(x), then at the maximum/minimum point, it holds:
f '(x) = 0
In the given problem, let:
q = length of the poster
p = width of the poster
Then,
p x q = 11760
or q = 11760/p
Let f(p,q) be the function of printed area, then:
f(p,q) = (p - 20)(q - 12)
f(p) = (p - 20) (11760/p - 12)
f(p) = -p² + 1000p - 980 x 20
At the maximum point:
f '(p) = 0
-2p + 1000 = 0
p = 500
Substitute p = 500 to get q:
q = 11760/p = 11760/500 = 23.52
Hence, the maximum printed area obtained if the dimensions are 500 cm x 23.52 cm

In part 1, we are given three signals and asked to identify their characteristics. The first signal is a pulse of width 2 units, which means it has a duration of 2 units and starts at t=5 and ends at t=7. The second signal is a sum of two pulses of width 1 unit each, which means it has two parts, each with a duration of 1 unit, and one starts at t=5 while the other starts at t=7. The third signal is a ramp starting at t=2 and ending at t=4, which means its amplitude increases linearly from 0 to 1 over a duration of 2 units.
In part 2, we are asked to sketch the signals. The first signal can be sketched as a rectangular pulse of height 1, starting at t=5 and ending at t=7. The second signal can be sketched as two rectangular pulses of height 1, one starting at t=5 and the other starting at t=7, with a gap of 2 units between them. The third signal can be sketched as a straight line starting at (2,0) and ending at (4,2), which means its amplitude increases linearly from 0 to 2 over a duration of 2 units. It is important to note that the height or amplitude of the signals in part 2 corresponds to the value of the signal in part 1 at that particular time.

find the area of the region bounded by the given curves. y = 6x2 ln(x), y = 24 ln(x)
Answers
The area of the region bounded by the given curves. y = 6x2 ln(x), y = 24 ln(x) is 2.85 sq.units.
In this question we need to find the area of the region bounded by the given curves. y = 6x^2 ln(x), y = 24 ln(x)
Equating both the equations of the curve,
6x^2 ln(x) = 24 ln(x)
24 ln(x) - 6x^2 ln(x) = 0
x = 1, 2
This means, the curves intersect at x = 1 and x = 2.
So, the required area would be,
A = ∫[1 to 2] [24 ln(x) - 6x^2 ln(x)] dx
First we find the indefinite integral ∫[24 ln(x) - 6x^2 ln(x)] dx
= -6 ∫[-4 ln(x) + x^2 ln(x)] dx
= -6 ∫ln(x) (x^2 - 4) dx
= -6 ln(x) (1/3 x^3 - 4x) + 2/3 x^3 - 24x
So, ∫[1 to 2] [24 ln(x) - 6x^2 ln(x)] dx
= [-6 ln(x) (1/3 x^3 - 4x) + 2/3 x^3 - 24x] _(x = 1 to x = 2)
= 32 ln(2) - 58/3
= 22.18 - 19.33
= 2.85 sq.units.
Therefore, the area of the region is 2.85 sq.units.

Because the final price was calculated by multiplying the initial price by 60%, we can represent that with the function:

Answers
Answer:
11.52 feet
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³, where V is the volume and r is the radius.
We can rearrange the formula to solve for the radius:
r = (3V/4π)^(1/3)
Substituting the given volume V = 7,234.56 ft³, we get:
r = (3(7,234.56)/(4π))^(1/3) ≈ 11.52 ft
Therefore, the radius of the sphere is approximately 11.52 feet.

Answers
False. The derivative of the function f(x) = 5sin(x) + cos(x) is not equal to -5cos(x) - sin(x). The correct derivative of f(x) can be obtained by applying the rules of differentiation.
To find the derivative, we differentiate each term separately. The derivative of 5sin(x) is obtained using the chain rule, which states that the derivative of sin(u) is cos(u) multiplied by the derivative of u. In this case, u = x, so the derivative of 5sin(x) is 5cos(x).
Similarly, the derivative of cos(x) is obtained as -sin(x) using the chain rule.
Therefore, the derivative of f(x) = 5sin(x) + cos(x) is:
f'(x) = 5cos(x) - sin(x).
This result shows that the derivative of f(x) is not equal to -5cos(x) - sin(x).
In summary, the statement that f'(x) = -5cos(x) - sin(x) is false. The correct derivative of f(x) = 5sin(x) + cos(x) is f'(x) = 5cos(x) - sin(x).
