Answer:
the sequence is geometric sequence with common ratio (-2).
Option : D is correct.
Step-by-step explanation:
In this question table is given as
n 1 2 3 4 5
f(n) 48 -96 192 -385 768
We have to find out if the sequence is arithmetic or geometric.
For Arithmetic sequence :
Difference should be common in each term of fees.
common difference = f(2) - f(1)
= -96 -48 = -144
similarly = f(3) - f (2) = 192 + 96 = 288
Here, ≠ so the sequence is not an arithmetic sequence.
For Geometric sequence :
Ratio should be common in each term of f(n)
Common ratio =

No fencing is required along the river. (See the figure below.) What are the dimensions of the largest area that can be enclosed? x = X yd y = 1590 yd What is this area? x yd2 Need Help?
The dimensions of the largest area that can be enclosed is 1590 × 795= 1264050 yd² when no fencing is required along the river.
Given the owner of the Rancho Los Feliz has 3180 yd of fencing to enclose a rectangular piece of grazing land along the straight portion of a river and then subdivide it by means of a fence running parallel to the sides. No fencing is required along the river.
We need to find the dimensions of the largest area that can be enclosed.
Therefore, the length of the land is the perimeter of the rectangle minus the river front.
We have; 2x + 3y = 3180 yd
Also, we can rewrite this equation in terms of x;
2x = 3180 - 3yy = (3180 - 2x) / 3
Substituting y in terms of x in the area equation;
Area A = x y= x(3180 - 2x) / 3
Taking the derivative of the area equation to find the maximum value of A;
A' = 1060 - 2x / 3 When A' = 0, x = 1590 / 2 = 795 yd.
Substitute x = 795 into the equation for y;
2(795) + 3y = 3180y = (3180 - 1590) / 3 = 530 yd
Therefore, the dimensions of the largest area that can be enclosed are; Length = 1590 yd Width = 795 yd
Hence, the area is given by; Area = Length × Width= 1590 × 795= 1264050 yd².

Astudent was asked to find a 99% confidence interval for the proportion of students who take notes using data from a random sample of size n - 83. Which of the following is a correct interpretation of the interval 0.14 « p<0.342?
The given confidence interval is 0.14 < p < 0.342, where p represents the proportion of students who take notes. To interpret this interval correctly, we can say: We are 99% confident that the true proportion of students who take notes lies between 0.14 and 0.342.
In other words, based on the data from the random sample of size 83, we estimate that the proportion of students who take notes falls within this range with a 99% level of confidence. This means that if we were to take multiple random samples of the same size and calculate confidence intervals, approximately 99% of those intervals would contain the true proportion of students who take notes.
Furthermore, the interval does not include the value of 0.5, which represents no preference or a 50% proportion. Since both 0.14 and 0.342 are less than 0.5, we can infer that the data suggests that a substantial proportion of students take notes, but we cannot conclude with certainty whether the majority or minority take notes without further information.
It's important to note that the interpretation assumes the random sampling method was appropriate and the sample is representative of the population of interest.

Find the absolute maximum and minimum values of the given function on the indicated inter- val. (a) f(x) = 31/3 - 3:2/3, on 11-,3).
The absolute maximum value of the function on the interval [-3, 1] is approximately 28.97, and the absolute minimum value is approximately 3.84.
To find the absolute maximum and minimum values of the function f(x) = 31/3 - 3x2/3 on the interval [-3, 1], we need to evaluate the function at its critical points and endpoints.
First, let's find the critical points by taking the derivative of the function:
f'(x) = (2/3)(31/3)(-3x^(-1/3)) = -2(31/3)(1/x^(1/3)) = -62/x^(1/3)
To find the critical points, we set f'(x) equal to zero and solve for x:
-62/x^(1/3) = 0
This equation has no solutions since the numerator is always non-zero.
Next, we evaluate the function at the endpoints of the interval:
f(-3) = 31/3 - 3(-3)^(2/3) ≈ 3.84
f(1) = 31/3 - 3(1)^(2/3) ≈ 28.97
Finally, we compare the values of the function at the critical points and endpoints to determine the absolute maximum and minimum:
Absolute maximum: f(1) ≈ 28.97
Absolute minimum: f(-3) ≈ 3.84
Therefore, the absolute maximum value of the function on the interval [-3, 1] is approximately 28.97, and the absolute minimum value is approximately 3.84.

Write a polynomial of least degree with roots 2 and – 7
Answer: x^2+5x-14
Step-by-step explanation:
2 and -7 are the roots of the polynomial then we have to write them as
x=2 ,x=-7
To convert these as factors, we have to write them as
( x-2) (x+7)
The product of those factors will give the polynomial. Because we have two factors, we will get a quadratic polynomial.
x^2+7x-2x-14
x^2+5x-14
Number of factors = Highest exponent of the polynomial
Answer:
y = x² + 5x - 14
Step-by-step explanation:
Given roots x = a, x = b, then the corresponding factors are
(x - a) and (x - b) and the polynomial is the product of the factors
y = (x - a)(x - b)
Here the roots are x = 2 and x = - 7, then the factors are
(x - 2) and (x - (- 7)) = (x + 7), so
y = (x - 2)(x + 7) ← expand using FOIL
y = x² + 5x - 14

Do there exist subspaces S,T, and U of R3 such that SIT, SIU, and T 1 U? If so, provide an example of such an S, T, and U, and prove that SIT, SIU, and T 10. If not, prove why they do not exist.
There exist no subspaces S, T, and U of R³ such that SIT, SIU, and T∩U.
In order to answer the given question, we first need to understand the definition of subspaces of a vector space.A subspace of a vector space is a subset that meets three requirements:
i) It includes the zero element of the vector space.
ii) It is closed under addition (if u and v belong to the subspace, then u + v is also in the subspace).
iii) It is closed under scalar multiplication (if u is in the subspace and k is a scalar, then ku is also in the subspace).
there exist no subspaces S, T, and U of R³ such that SIT, SIU, and T∩U.
The reason is simple because if T∩U = Ø, then either SIT or SIU will be the trivial subspace {0}.
However, this contradicts the fact that both SIT and SIU have to contain a non-zero vector as they are subspaces that are generated by S, T, and U.
Therefore, it is proven that there exist no subspaces S, T, and U of R³ such that SIT, SIU, and T∩U.

The area between the graph of y = f(x) and the x-axis on the interval [a, b] by evaluating the definite integral of f(x) over that interval.
The definite integral of f(x) from a to b represents the signed area between the graph of f(x) and the x-axis. The sign of the area depends on the behavior of f(x) above and below the x-axis.
If f(x) is non-negative (greater than or equal to 0) on the interval [a, b], then the area between the graph of f(x) and the x-axis will be positive or zero.
If f(x) is non-positive (less than or equal to 0) on the interval [a, b], then the area between the graph of f(x) and the x-axis will be negative or zero.
If f(x) changes sign on the interval [a, b] (i.e., it is positive in some regions and negative in others), then the area between the graph of f(x) and the x-axis will be the sum of the positive areas minus the sum of the negative areas.

A set H in R² is displayed on the right. Assume the set includes the bounding lines. Determine whether H is a subspace of R² and justify.
To determine whether set H is a subspace of R², we need to check if H satisfies the three requirements for a subspace: closure under addition, closure under scalar multiplication, and contains the zero vector.
To determine if set H is a subspace of R², we need to check if it satisfies the three properties of a subspace.
Closure under addition: For any two vectors u and v in H, their sum u + v should also be in H. If the lines forming the boundary of H extend infinitely, then any two vectors u and v in H can be added to form a vector that lies within H. Thus, H is closed under addition.
Closure under scalar multiplication: For any vector u in H and any scalar c, the scalar multiple cu should also be in H. Similarly to the closure under addition, if the lines forming the boundary of H extend infinitely, then any vector u in H can be multiplied by a scalar to obtain a vector that lies within H. Hence, H is closed under scalar multiplication.
Contains the zero vector: The zero vector (0, 0) is part of R² and is also part of H since it lies within the boundary of H.
Since H satisfies all three requirements, it is a subspace of R².

Determine the number of ways 7 books can be arranged on a shelf if a) there are no restrictions?
The number of ways seven books can be arranged on a shelf if there are no restrictions is 7! = 5040.Why? As there are no restrictions, any of the seven books can occupy any of the seven places on the shelf. Therefore, there are 7 ways to place the first book. After the first book has been placed, there are 6 ways to place the second book (as one place is now occupied).Then, after the first and second books have been placed, there are 5 ways to place the third book (since two places are now occupied). Similarly, there are 4 ways to place the fourth book after the first four have been placed. There are 3 ways to place the fifth book after the first five have been placed.
There are 2 ways to place the sixth book after the first six have been placed. There is only one way to place the last book after the first six have been placed.
So, using the Multiplication Principle, the number of ways 7 books can be arranged on a shelf is:7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040.

A debt of $25,000 is to be amortized over 17 years at a 7% annual interest rate under monthly compounding. What value of monthly payments will achieve this? Please round your numerical answer to the nearest integer dollar.
After considering the given data we conclude that value of monthly payments will achieve this is $25,000 over 17 years at a 7% annual interest rate under monthly compounding is $203.
To evaluate the monthly payments that will amortize a debt of $25,000 over 17 years at a 7% annual interest rate under monthly compounding, we could apply the following steps:
Alter the annual interest rate to a monthly interest rate by applying division of 12. The monthly interest rate is 7% / 12 = 0.5833%.
Alter the number of years to the number of months by multiplying by 12. The number of months is 17 × 12 = 204.
Apply the formula for the monthly payment on an amortized loan:
[tex]P = (r * PV) / (1 - (1 + r)^{(-n))}[/tex]
Here,
P = monthly payment,
r = monthly interest rate,
PV = present value of the loan (which is $25,000),
n = total number of payments (which is 204).
Placing in the values, we get:
[tex]P = (0.005833 * 25000) / (1 - (1 + 0.005833)^{(-204))} = $202.91[/tex]
Hence, the monthly payments that will amortize the debt of $25,000 over 17 years at a 7% annual interest rate under monthly compounding is $203 (rounded to the nearest dollar).

Now,
To solve for x in the equation 2x+9=4x+1, we need to isolate x on one side of the equation.
First, we can simplify both sides by subtracting 2x from each side:
2x+9-2x=4x+1-2x
Simplifying this gives us:
9=2x+1
Next, we can subtract 1 from each side:
9-1=2x+1-1
Simplifying this gives us:
8=2x
Finally, we can divide both sides by 2:
8/2=2x/2
Simplifying this gives us:
