The integrat (cos(x - 3) dx is transformed into L' (t)dt an g(t) = 1/2 sin(t-3/2) is incorrect. The correct option g(t) = 1/2 cos(t-3/2).
To transform the integral ∫cos(x - 3)dx into L'(t)dt using an appropriate change of variable, the substitution method make the substitution:
t = x - 3
To find dt, differentiate both sides of the equation with respect to x:
dt = dx
substitute these expressions into the integral:
∫cos(x - 3)dx = ∫cos(t)dt
The integral has been transformed into ∫cos(t)dt.
regarding the options for g(t),
Option 1: g(t) = 1/2 cos(t-3/2)
Taking the derivative of g(t) with respect to t,
g'(t) = -(1/2)sin(t - 3/2)
Option 2: g(t) = 1/2 sin(t-3/2)
Taking the derivative of g(t) with respect to t,
g'(t) = (1/2)cos(t - 3/2)

During the summer John collected cans to recycle. In August he collected 718 cans bringing his total to 2,275 cans. How many cans did John collect before August?
Answer: 1557 cans
Step-by-step explanation:
Since we are informed that John collected 718 cans in August bringing his total number of cans to 2,275 cans, the number of cans that John collected before August will be:
= Total number of cans collected - Number of cans collected in August
= 2275 - 718
= 1557 cans

so, it is 2 to the power integers.
Software can generate samples from (almost) exactly Normal distributions.
Here is a random sample of size 5 from the Normal distribution with mean 10 and standard deviation 2:
6.47 7.51 10.10 13.63 9.91
These data match the conditions for a z test better than real data will: the population is very close to Normal and has known standard deviation s = 2, and the population mean is µ = 10.
Test the hypotheses
H0 : µ = 8
Ha : µ ? 8
In Exercise 15.41 (given above), a sample from a Normal population with mean µ = 10 and standard deviation s = 2 failed to reject the null hypothesis H0 : µ = 8 at the a = 0.05 significance level.
Enter the information from this example into the Power of a Test applet.
(Don't forget that the alternative hypothesis is two-sided.)
What is the power of the test against the alternative µ = 10?
The power of the test against the alternative µ = 10 is 1.
Given: A sample from a Normal population with mean µ = 10 and standard deviation s = 2 failed to reject the null hypothesis
H0: µ = 8 at the a = 0.05 significance level.
To find :
The power of the test against the alternative µ = 10.
Step 1: We have
H0 : µ = 8
Ha: µ ≠ 8α
= 0.05
Sample size n = 5
Population Standard deviation s = 2
Population means µ = 10
The alternative hypothesis is two-sided.
Hence α/2 = 0.025.
Using a normal table, the critical values for a two-tailed test at the 0.05 level of significance are -1.96 and +1.96 respectively.
Step 2: We know that
[tex]\[z=\frac{\overline{x}-\mu }{\frac{s}{\sqrt[]{n}}}\][/tex]
where [tex]\[\overline{x}\][/tex] = sample mean,
µ = Population mean,
s = Population Standard deviation and
n = sample size.
By using the given data, z can be calculated as below:
[tex]\[z=\frac{10-8}{\frac{2}{\sqrt[]{5}}}[/tex]
=[tex]4.47[/tex]
The value of z falls in the critical region if it is less than -1.96 or greater than +1.96.
Since 4.47 is greater than +1.96, the null hypothesis is rejected.
Since the null hypothesis is rejected, it is logical to expect that the power of the test will be high.
Hence, the power of the test against the alternative µ = 10 is 1 (100%).

Use the SOR method with w = 1.2 to solve the following linear system with a tolerance TOL = 10-3 in the lo norm. - 4x1 + x2 – x3 + x4 = -2, X1 + 4x2 – X3 – X4 = -1, -X] – x2 + 5x3 + x4 = 0, X1 – x2 + x3 + 3x4 = 1.
Using the Successive Over-Relaxation (SOR) method with a relaxation factor of w = 1.2 and a tolerance of TOL = 10^-3 in the l2 norm, the linear system of equations can be solved iteratively. The solution will converge to the desired tolerance level.
The SOR method is an iterative technique used to solve linear systems of equations. It requires an initial guess for the solution and iteratively updates the values until the desired tolerance is reached.
To apply the SOR method, the given linear system can be rewritten as a matrix equation: AX = B, where A is the coefficient matrix, X is the solution vector, and B is the constant vector. The system can be solved by iterating through the equations and updating the values of X until convergence is achieved.
In this case, the SOR method is performed with a relaxation factor of w = 1.2, which helps to accelerate convergence. The tolerance is set to TOL = 10^-3, indicating the desired level of accuracy.
The SOR algorithm is then applied iteratively until the solution converges within the specified tolerance. The updated values of X are calculated using the SOR formula, and the process is repeated until the difference between consecutive iterations falls below the tolerance level.
By following this iterative process with the given parameters, the SOR method will yield the solution to the linear system of equations.

find the lengths of the sides of the triangle with the indicated vertices, and determine whether the triangle is a right triangle, an isosceles triangle, or neither. a(3, 4, 1), b(0, 6, 2), c(3, 5, 6)
The lengths of the sides of the triangle ABC are √14, √26, and √26, and the triangle is neither a right triangle nor an isosceles triangle.
To find the lengths of the sides of the triangle with vertices A(3, 4, 1), B(0, 6, 2), and C(3, 5, 6), we can use the distance formula.
The distance formula between two points (x₁, y₁, z₁) and (x₂, y₂, z₂) in three-dimensional space is given by:
d = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)
Let's calculate the lengths of the sides of the triangle:
Side AB:
d₁ = √((0 - 3)² + (6 - 4)² + (2 - 1)²)
= √((-3)² + 2² + 1²)
= √(9 + 4 + 1)
= √14
Side BC:
d₂ = √((3 - 0)² + (5 - 6)² + (6 - 2)²)
= √(3² + (-1)² + 4²)
= √(9 + 1 + 16)
= √26
Side AC:
d₃ = √((3 - 3)² + (5 - 4)² + (6 - 1)²)
= √(0² + 1² + 5²)
= √(0 + 1 + 25)
= √26
Now, let's analyze the triangle based on the lengths of its sides:
Since all three sides have different lengths (√14, √26, and √26), the triangle is neither an isosceles triangle (which has at least two sides of equal length) nor a right triangle (which satisfies the Pythagorean theorem).
In summary, the lengths of the sides of the triangle ABC are √14, √26, and √26, and the triangle is neither a right triangle nor an isosceles triangle.

What is the range of the function f = [0,00) + R, defined by the rule f(t) = -247 (a) (0,1) (c) R (b) (0,11 (d) (0,00)
The range of the function f = [0,00) + R, defined by the rule f(t) = -247 is {-247}. The correct option is d.
The range of a function is the set of all possible outputs or y-values. Here, the function is f(t) = -247 with the domain [0,00), which means that for any value of t between 0 and 00 (excluding 00), the function will always give the same output, -247. This is because the rule for the function is simply -247, and doesn't depend on the input value of t.
The range of the function f is simply {-247}, which is a singleton set containing only one element (-247). In other words, the only possible output or y-value for this function is -247, and there are no other possible values for f(t) for any value of t between 0 and 00 (excluding 00).
Thus, the correct option is d.

U (X): 0 3 4.5 6 7 8 9 10 11 12 13 14 15
(a) Calculate the probabilities p1 and p2 such that 45 is indifferent to the lotteries: (20, p1; 150, 1 −p1) and (−20, p2; 110, 1 −p2)
(b) Calculate the selling price and risk premiums of the lotteries: (−90, 0.5; −20, 0.5) and (−100, 0.2; −50, 0.3; −20, 0.4; 70, 0.1).
(c) Calculate the buying price for the following lottery (150, 0.4; 45, 0.6).
If utility function is given then we set up U(45) = p2 * U(-20) + (1 - p2) * U(110) and solve for p2.
(a) To find the probabilities p1 and p2, we set up the equation U(45) = p1 * U(20) + (1 - p1) * U(150) and solve for p1. Similarly, we set up U(45) = p2 * U(-20) + (1 - p2) * U(110) and solve for p2.
(b) The selling price of a lottery is the amount at which an individual is willing to sell the lottery. We compare the expected utility of the lottery to the utility of the certain amount. The risk premium is the difference between the selling price and the expected value of the lottery.
(c) The buying price is the amount an individual is willing to pay for a lottery. We set up the equation U(45) = p * U(150) + (1 - p) * U(45) and solve for p to find the buying price.
Note: The specific calculations for parts (a), (b), and (c) require the values of U(X) for each corresponding X value in the utility function.

solve the problem. determine if the lower bound theorem identifies -4 as a lower bound for the real zeros of f(x). f (x) = 3x3 2x2 - 9x 4 select one: a. yes b. no
The correct answer is: a. yes. To determine if the lower bound theorem identifies -4 as a lower bound we need to analyze the behavior of the function as x approaches negative infinity.
The lower bound theorem states that if a polynomial function has a negative leading coefficient (in this case, 3), then any lower bound M must have the property that f(M) is either negative or zero.
Let's evaluate f(-4) to see if it is negative or zero: f(-4) = 3(-4)^3 + 2(-4)^2 - 9(-4) + 4= 3(-64) + 2(16) + 36 + 4= -192 + 32 + 36 + 4= -120. Since f(-4) = -120 is negative, the lower bound theorem identifies -4 as a lower bound for the real zeros of f(x).Therefore, the correct answer is: a. yes

Write an equation of the line perpendicular to the given line that contains P.
John is 30 years old. He will receive two payments of $2500 each. The first payment will be an unknown number of years in the future. The second payment will be five years after the first payment. At an annual effective interest rate of I=5%, the present value of the two payments is $2606. Determine at what age John will receive the second payment.
Answer:
16 years
Step-by-step explanation:
Let us assume that he would received the first payment after t years
So
The following formula should be used
PV = P ÷ (1 + r)^t + P ÷ (1 + r)^t+5
$2,606 = $2,500 ÷ (1 + 0.05)^t + $2,500 ÷ (1 + 0.05)^t + 5
$2,606 = $2,500 ÷ 1.05^t (1 + 1 ÷ (1.05)^5)
1.05^t = $2,500 ÷ $2,606 (1.7835) = 1.71098
t = ln(1.71098) ÷ ln(1.05)
= 11
Therefore he would be received the second payment after

Given the figure below, find the values of x and z.
Answer:
x = 12
z = 101
Step-by-step explanation:
Hello There!
First lets find z
Well the angle that has a measure of 79 degrees and angle z are supplementary angles meaning that the sum of the two is 180
So we can find the missing angle by subtract the given angle (79 in this case) from 180
180 - 79 = 101 so z = 101
Now lets find x
The angle that has a measure of 79 degrees and the angle labeled (6x+7) are vertical angles
If you didn't know vertical angles are congruent
That being said lets create an equation to solve for x
79 = 6x + 7
now we solve for x
step 1 subtract 7 from each side by
7 - 7 cancels out
79 - 7 = 72
now we have 72 = 6x
step 2 divide each side by 6
72/6=12
6x/6=x
we're left with x = 12
