Quantrell bought a television set on sale for his apartment for $1,500, but he will spread the payments over two years. The store charges 18 percent interest for financing, and his payments will be $74.89. Hence, he will pay $1650.22 in interest over the life of the loan.

How much will he pay in interest over the life of the loan?He bought a television set on sale for $1500 that he will spread the payments over two years.The total amount he will pay in two years for the TV is obtained by adding up the cost of the TV set and the interest over the life of the loan. To compute the interest, we will first find the total payment he will make in two years.

To find the total payment, multiply the number of payments by the amount of each payment. Then,Total payment = Number of payments × Amount of each paymentSubstituting the values of number of payments and amount of each payment, we get:Total payment = 2 × $74.89Total payment = $149.78Now, let's calculate the interest on the loan,Interest = Total payment − Cost of the TV setInterest = $149.78 − $1500Interest = $1650.22

The volume V of solid S is e - 1 cubic unit.

What is Volume?

Volume refers to the measure of three-dimensional space occupied by an object or a region. It quantifies the amount of space enclosed by the boundaries of an object or contained within a given region. In mathematical terms, volume is often calculated by integrating the cross-sectional areas of the object or region along a particular axis. Volume is typically expressed in cubic units, such as cubic meters (m^3) or cubic centimeters (cm^3). It is an essential concept in geometry, physics, engineering, and other scientific fields where the measurement of three-dimensional space is involved.

To find the volume of solid S, we need to integrate the areas of the cross sections perpendicular to the x-axis along the interval \([e, \infty).\)

The area of each square cross-section is equal to the square of the side length, which in this case is \(y = \sqrt{\ln(x)}.\)

Therefore, the volume V of solid S can be calculated as:

\(V = \int_{e}^{\infty} (\sqrt{\ln(x)})^2 dx\)

To evaluate this integral, we can simplify the expression:

\(V = \int_{e}^{\infty} \ln(x) dx\)

Using integration by parts, we let \(u = \ln(x)\)and dv = dx:

\(du = \frac{1}{x} dx\\v = x\)

Applying the integration by parts formula:

\(V = [uv] - \int v du= [x \ln(x)] - \int x \left(\frac{1}{x}\right) dx= x \ln(x) - \int dx= x \ln(x) - x + C\)

Evaluating the definite integral:

\(V = [x \ln(x) - x]_{e}^{\infty}= (\infty \cdot \ln(\infty) - \infty) - (e \cdot \ln(e) - e)= \infty - 0 - (1 - e)= e - 1\)

Therefore, the volume V of solid S is e - 1 cubic unit.

The closest correlation of rates of return between stocks a and b is approximately -0.487 (negative), indicating opposite movements.

The relationship coefficient between two stocks an and b can be determined utilizing the equation:

relationship coefficient = covariance/(standard deviation of stock a * standard deviation of stock b)

Considering that the covariance between the profits of stocks an and b is - 0.073, and the standard deviation of the paces of return is 0.5 for stock an and 0.3 for stock b, we can substitute these qualities into the recipe to track down the connection coefficient.

relationship coefficient = - 0.073/(0.5 * 0.3) ≈ - 0.487

Consequently, the nearest worth of the connection of the paces of return between stock an and b is - 0.487. This negative relationship coefficient demonstrates that the profits of the two stocks will generally move in inverse bearings. At the point when one stock's return is high, the other stock's return is probably going to be low, as well as the other way around.

Answer:

96 squared meters

Step-by-step explanation:

Area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

To solve this, we need to first find out how big the area is with the path. To do this, we need to add the 2m on to the length and width of the lawn.

Now, we have the numbers we need to solve for the total area. If we know that the area can be solved using length × width, we can use this equation:

So, the lawn's area including the fence is 576 square meters.

To find out the area of just the fence, we can take the area of the lawn with the fence and subtract the area of the lawn from it. The equation can look like this:

Therefore, the area of the path is 96 squared meters.

Answer:

The area of the path is 200 m².

Step-by-step explanation:

To find the area of the path, subtract the area of the lawn from the area of the path and lawn.

If a lawn that is 30 m long and 16 m wide is surrounded by a path that is 2 m wide, then the length and width of the area of the path and lawn is 34 m long and 20 m wide.  

Given the area of a rectangle is the product of the measures of its length and width:

The solution to the given differential equation is: x⁷ cos y = y + C

where C is the constant of integration

To solve the given differential equation:

\(\[7x^6\cos y dx - dy = 0\]\)

We can separate the variables and integrate both sides.

Separating variables, we can write the equation as:

\(\[7x^6\cos y dx = dy\]\)

Now, we can integrate both sides with respect to their respective variables:

\(\[\int 7x^6\cos y dx = \int dy\]\)

Integrating the left side:

\(\[\int 7x^6\cos y dx = 7 \int x^6 \cos y dx\]\)

To integrate \(\(x^6 \cos y\)\)with respect to x, we can use integration by parts.

Let's take u = x⁶ and \(\(dv = \cos y dx\)\).

Differentiating u with respect to \(\(x\) gives \(du = 6x^5 dx\).\)

Integrating dv with respect to x gives \(\(v = \int \cos y dx = \cos y \cdot x\).\)

Applying the integration by parts formula:

\(\[\int x^6 \cos y dx = u \cdot v - \int v \cdot du\]\)

Substituting the values:

\(\[\int x^6 \cos y dx = x^6 \cdot \cos y \cdot x - \int (\cos y \cdot x) \cdot (6x^5 dx)\]\)

Simplifying:

\(\[\int x^6 \cos y dx = x^7 \cos y - 6 \int x^6 \cos y dx\]\)

Moving the integral term to the left side:

\(\[7 \int x^6 \cos y dx = x^7 \cos y\]\)

Dividing both sides by 7:

\(\[\int x^6 \cos y dx = \frac{x^7 \cos y}{7}\]\)

Now, substituting this result back into our original equation:

\(\[7 \int x^6 \cos y dx = dy\]\)

\(\[\frac{7x^7 \cos y}{7} = dy\)

Simplifying:

x⁷ cos y = dy

Finally, the solution to the given differential equation is:

x⁷ cos y = y + C

b. A polynomial P(x) is divided by x - a, the remainder is zero. What can we conclude?

Using the factor theorem, if p(x) is a polynomial and x - a is a linear factor, then if x - a is a factor of p(x), then the remainder when p(x) is divided by x - a is zero.

So, from the above since the remainder when P(x) is divided by x - a is zero, then x - a is a factor of P(x)
