Answer:

The rate of decrement is given as: r = 4%. From the table, the initial population is. P (0) = 7900. So, the population in t years is. P (t) = P (0) * (1 - r)^t. This gives. P (t) = 7900 * (1 - 4%)^t. Evaluate the difference.

Population after 2 years = P (1 + 4/100)2 = 62500 X (104/100)2

= 62500 × 26/25 X 26/25 = 100 × 26 ×26 = 67600.

Answer:

  5 m

Step-by-step explanation:

The length of the side of a square is the root of the area of the square. The area of this square is the difference between the trapezoid area and the triangle area.

__

  square area = trapezoid area - triangle area

  square area = 57.5 m² -32.5 m² = 25 m²

Then the side length is ...

  side length = √(square area) = √(25 m²)

  side length = 5 m

The length of a side of the square is 5 m.

Let's solve the given problem. Suppose v is an eigenvector of a matrix A with eigenvalue 5 and an eigenvector of a matrix B with eigenvalue 3.

We are to determine the eigenvalue λ corresponding to v as an eigenvector of 2A² + B².We know that the eigenvalues of A and B are 5 and 3 respectively. So we have Av = 5v and Bv = 3v.Now, let's find the eigenvalue corresponding to v in the matrix 2A² + B².Let's first calculate (2A²)v using the identity A²v = A(Av).Now, (2A²)v = 2A(Av) = 2A(5v) = 10Av = 10(5v) = 50v.Note that we used the fact that Av = 5v.

Therefore, (2A²)v = 50v.Next, let's calculate (B²)v = B(Bv) = B(3v) = 3Bv = 3(3v) = 9v.Substituting these values, we can now calculate the eigenvalue corresponding to v in the matrix 2A² + B²:(2A² + B²)v = (2A²)v + (B²)v = 50v + 9v = 59v.We can now write the equation (2A² + B²)v = λv, where λ is the eigenvalue corresponding to v in the matrix 2A² + B². Substituting the values we obtained above, we get:59v = λv⇒ λ = 59.Therefore, the eigenvalue corresponding to v as an eigenvector of 2A² + B² is 59.

Answer:

Step-by-step explanation:

The area of the computer monitor display is approximately 0.103 square meters, with three significant figures.

The area of the monitor display in square meters is found by converting the measurements from inches to meters and then calculate the area.

The conversion factor from inches to meters is 0.0254 meters per inch.

Width in meters = 14.60 inches * 0.0254 meters/inch

Height in meters = 10.95 inches * 0.0254 meters/inch

Area = Width in meters * Height in meters

We calculate the area:

Width in meters = 14.60 inches * 0.0254 meters/inch = 0.37084 meters

Height in meters = 10.95 inches * 0.0254 meters/inch = 0.27813 meters

Area = 0.37084 meters * 0.27813 meters = 0.1030881672 square meters

Now, we determine the number of significant figures.

The measurements provided have four significant figures (14.60 and 10.95). However, in the final answer, we should retain the least number of significant figures from the original measurements, which is three (10.95). Therefore, the answer should have three significant figures.

Thus, the area of the monitor display in square meters is approximately 0.103 square meters, with three significant figures.

The B coordinate vector for \($-1+2t$\) will be:

\(\[\begin{bmatrix}c_1 \\c_2 \\c_3 \\\end{bmatrix}\]\)

What is linear algebra?

Linear algebra is a branch of mathematics that deals with the study of vector spaces, linear transformations, and systems of linear equations. It focuses on the properties and operations of vectors and matrices, as well as their relationships and transformations.

To find the B coordinate vector for a given vector in the standard basis, you need to express that vector as a linear combination of the basis vectors of B. Here's how you can approach it:

1. Given vector:\($-1+2t$\)

2. Write the given vector as a linear combination of the basis vectors of B:

\($-1+2t = c_1(1-2t+t^2) + c_2(3-5t+4t^2) + c_3(2t+3t^2)$\)

3. Equate the coefficients of corresponding terms:

 \($-1 + 2t = c_1 + 3c_2$\\\\ $0t = -2c_1 - 5c_2 + 2c_3$ \\ \\$0t^2 = c_1 + 4c_2 + 3c_3$\)

4. Solve the system of equations to find the values of \(c_1$, $c_2$, and $c_3$.\)

By solving the system of equations, you can find the values of \(c_1$, $c_2$, and $c_3$\) , which will form the B coordinate vector for the given vector \(-1+2t$.\) Substitute the values back into the linear combination equation to obtain the B coordinate vector.

Once you have the values of \($c_1$, $c_2$, and $c_3$,\) the B coordinate vector for \($-1+2t$\) will be:

\(\[\begin{bmatrix}c_1 \\c_2 \\c_3 \\\end{bmatrix}\]\)

In the absence of price discrimination, the profit-maximizing conditions would be different, and the resulting prices, quantities, total revenue, total cost, and profit would also be different.

To find the profit-maximizing conditions with third-degree price discrimination, we need to equate the marginal revenue (MR) to the marginal cost (MC) for each market segment.

Given the demand equations and the total cost function:

Market 1: Q1 = 160 - 10P1 or P1 = 16 - 0.1Q1

Market 2: Q2 = 200 - 20P2 or P2 = 10 - 0.05Q2

Total Cost: TC = 120 + 4Q

To find the profit-maximizing prices and quantities, we equate MR to MC for each market segment:

MR1 = MC:

16 - 0.2Q1 = 4

0.2Q1 = 12

Q1 = 60

MR2 = MC:

10 - 0.1Q2 = 4

0.1Q2 = 6

Q2 = 60

Substituting the quantities back into the demand equations, we find:

P1 = 16 - 0.1(60) = 10

P2 = 10 - 0.05(60) = 7

The total revenue (TR) can be calculated by multiplying the price by the quantity for each market segment:

TR = P1 * Q1 + P2 * Q2

TR = (10 * 60) + (7 * 60)

TR = 600 + 420

TR = 1020

The total cost (TC) is given by the total cost function:

TC = 120 + 4Q

TC = 120 + 4(60 + 60)

TC = 120 + 480

TC = 600

Finally, the profit (π) can be calculated by subtracting total cost from total revenue:

π = TR - TC

π = 1020 - 600

π = 420

In the absence of price discrimination, the profit-maximizing conditions would be different, and the resulting prices, quantities, total revenue, total cost, and profit would also be different.

(By the way T^2 = A^3 is called Kepler's Third Law.  Actually Johannes Kepler stated it as:

T^2 = R^3 where "r" means radius of orbit.)

Step-by-step explanation:

If planet Y is twice the mean distance from the sun as planet X, then by a factor of \(2^{\frac{3}{2}}\) is the orbital period increased and this can be determined by using the given data.

Given :

The equation T squared = A cubed shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A, in astronomical units, AU.

The following steps can be used to determine the factor from which the orbital period increased:

Step 1 - Write the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A, in astronomical units, AU.

\(\rm T^2=A^3\)

Step-by-step explanation:

The rate of increase in population size will depend on the magnitude of the difference between the birth and death rates, as well as the extent of emigration and immigration.

If the number of births in a population are greater than the number of deaths and the emigration rate is 2x the immigration rate, then the population size is likely to increase over time. This is because there are more individuals being born than dying, and even though there is a higher emigration rate, the net effect is still an increase in population size. However, the rate of increase in population size will depend on the magnitude of the difference between the birth and death rates, as well as the extent of emigration and immigration.
If the number of births in a population is greater than the number of deaths, and the emigration rate is 2x the immigration rate, the population size is likely to experience some growth due to the excess of births over deaths. However, the growth may be slowed down or even potentially decrease over time, as the higher emigration rate could lead to more people leaving the population than entering it. The overall change in population size will depend on the balance between these factors.

The number of inches burned from the candle is represented by 1.2t, while the remaining length of the candle is given by 12.5 - 1.2t. The first two statements are true, but the third statement is false.

a. The expression representing the number of inches burned from the candle since it was lit can be calculated by multiplying the rate of burning (1.2 inches per hour) by the number of hours elapsed (t). Therefore, the expression is 1.2t.    b. To find the remaining length of the candle, subtract the number of inches burned from the original length of the candle. The original length is 12.5 inches, so the expression representing the remaining length is 12.5 - 1.2t.     c. The first statement is true. The number of inches burned is indeed proportional to the time since the candle has been burning, as given by the expression 1.2t.

The second statement is also true. The remaining length of the candle decreases linearly with time, following the expression 12.5 - 1.2t.

The third statement is false. The change in the candle's height is not proportional to the amount of time since it has been burning. It is only proportional to the number of inches burned, not the time itself.

The 9th term of the geometric sequence is 1,562,500.

Let the first term of the geometric sequence be "a" and the common ratio be "r".

From the given information, we know that:

2nd term = a * r = 20                  ---(1)

5th term = a * r^4 = 2500             ---(2)

Dividing equation (2) by equation (1), we get:

(a * r^4)/(a * r) = 2500/20

r^3 = 125

r = 5

Substituting this value of r in equation (1), we get:

20 = a * 5

a = 4

So the geometric sequence is: 4, 20, 100, 500, 2500, ...

To find the term that is 1,562,500, we can use the formula for the nth term of a geometric sequence:

an = a * r^(n-1)

Setting this equal to 1,562,500 and solving for n, we get:

1,562,500 = 4 * 5^(n-1)

5^(n-1) = 390625

n - 1 = log_5(390625)
