The total principal and interest payment that Nelson will have to pay after 2 months is $4665.50.

To calculate the total principal and interest payment, we need to determine the interest amount and add it to the principal.

First, let's find the interest amount:

Interest = Principal x Interest Rate x Time

Given:

Principal = $4650

Interest Rate = 2% per year

Time = 2 months

Since the interest rate is given on an annual basis, we need to convert the time from months to years. There are 12 months in a year, so 2 months is equivalent to 2/12 = 1/6 years.

Interest = $4650 x 0.02 x (1/6) = $15.50

Now, we can calculate the total principal and interest payment:

Total Payment = Principal + Interest

Total Payment = $4650 + $15.50 = $4665.50

After 2 hours the plan needs to be changed, and purchase solar for the cost effect.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that:

At 6 AM today, you purchased 1 MW of electricity contract for 12 PM at a price of 100 pounds/MWh.

Total cost = 6x100 = 600 pounds

Total cost for 2 hours = 200 pounds

Two hours later, the forecast for solar generation for 12 PM has changed from 4 GW to 4.5 GW.

Total cost for this:

From 8 AM to 12 PM = Number of hours 4 hours

4.5 GW = 4500 MW

= 105 pounds/MWh

Total cost for  4 hours = 630 pounds for 4500 MW per hour

Thus, after 2 hours the plan needs to be changed, and purchase solar for the cost effect.

a. The value of sin θ = 13/18

b. The size of sin θ is 46.2 degrees

First, we need to know the different trigonometric identities.

These trigonometric identities are listed thus;

From trigonometric relations, we have that the ratio for sine identity is represented as;

sin θ = opposite/hypotenuse

Then, we have from the information given that;

Hypotenuse side = 18cm

Opposite side = 13cm

Substitute the values, we have;

sin θ = 13/18

Divide the values

sin θ = 0. 7222

Find the sine inverse value, we have;

so, θ = sin⁻¹(13/18) = 46. 2 degrees

The expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2) Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

The property of exponents that must be applied to the expression p^(1/2) to derive p as the result is the Power of a Power Property.

The Power of a Power Property states that when a power is raised to another power, the exponents are multiplied.

For instance, consider the expression p^(1/2). We can apply the Power of a Power Property to this expression as follows: p^(1/2) = (p^(1/2))^1 By applying the Power of a Power Property, the exponent (1/2) is multiplied by the exponent 1, giving a result of 1/2.

Therefore, the expression becomes: p^(1/2) = p^(1/2 * 1) = p^(1/2)Now we can simplify p^(1/2) as p^1/2 which equals the square root of p.

So we have derived p as the result using the Power of a Power Property.

In summary, we must apply the Power of a Power Property to the expression p^(1/2) to derive p as the result.

Answer:

296.5 miles

Step-by-step explanation:

Round trip distance of City X to City Y is 647 miles.

Round trip includes to and fro.

i.e. City X to City Y and then City Y to City X back.

Let the distance between City X and City Y = D

Distance traveled in round trip between City X and City Y = D + D = 2D

Given than 2D = 647

OR

D = \(\frac{647}2\) = 323.5 miles

Kindly refer to the attached diagram, for the location of City Z.

Distance between XY = Distance from X to Z + Distance from Z to Y.

Given statement solution is :- The present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

To calculate the present value of an investment with compound interest, we can use the formula for the present value of an annuity:

PV = A *\((1 - (1 + r)^(-n)) / r\)

Where:

PV = Present value

A = Annual payment or cash flow

r = Interest rate per period

n = Number of periods

In this case, the annual payment (A) is R13,000, the interest rate (r) is 10% per year, and the investment is made for 8 years (n).

Using the formula and substituting the given values, we can calculate the present value:

PV = \(13000 * (1 - (1 + 0.10)^(-8)) / 0.10\)

Calculating this expression:

PV = \(13000 * (1 - 1.10^(-8)) / 0.10\)

= 13000 * (1 - 0.46318) / 0.10

= 13000 * 0.53682 / 0.10

= 6977.66 / 0.10

= 69776.6

Therefore, the present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

B. A mosaic has an area of \frac{3}{4} square foot and a width of \frac{1}{5} foot. What is the length of the mosaic?

Step-by-step explanation:

Mathematic representation of a story

Real-life problems involving calculations usually come as stories. The mathematician must be able to represent them in the mathematics language to solve them.

This is an unusual case where the maths are given, and we must find the equivalent story that generated it.

Recall the area of a rectangular shape of length L and width W is:

A = L*W

If we had the area and wanted to calculate the width or the length, we can solve for the required variable as follows:

\(\displaystyle L=\frac{A}{W}\)

\(\displaystyle W=\frac{A}{L}\)

We are given the division:

\(\displaystyle \frac{3}{4}\div \frac{1}{5}\)

can be the calculation of any of the above-mentioned situations.

Note that in both cases, the area is the dividend or the numerator of the fraction. This leads to preselect only the options that provide an area of 3/4 as part of the data.

Only option B. uses 3/4 as the area of the rectangular shape. As 1/5 is the other dimension of the rectangle, this is the correct answer.

Orbital period of the planet is 2√2 earth years

According to Kepler's third law, the square of a planet's orbital period is proportional to the cube of its semi major axis.  

T² α a³

where, T is orbital period and a is length of semi-major axis.

Given,

Distance between the sun and the planet

= twice the distance of sun and earth

Let distance between sun and earth a₁ = d

then distance between planet and sun a₂= 2d

Orbital period of earth T₁ = 1 earth year

By Kepler's third law

T² α a³

(T₁/T₂)² = (a₁/a₂)³

(1/T₂)² = (D/2D)³

1/T₂² = 1/8

T₂ = 2√2 earth years

Hence, 2√2 earth years is the orbital period of other planet.

In conclusion, none of the given statements are correct based on the information provided.

To determine the correct statement, let's analyze the given information and the regression equation:

The regression equation for estimating the number of customers on a given day is y = 1.03x + 229.4, where x represents the day number and y represents the number of customers served.

We are also given that the restaurant has been making a net profit of $5.82, on average per customer:

Now let's evaluate each statement:

A. On day 7, the owner can expect 15 more customers than she has served on day 6.

To determine the number of customers on day 7, we substitute x = 7 into the regression equation:

y = 1.03(7) + 229.4 = 7.21 + 229.4 = 236.61

So, the number of customers on day 7 is approximately 237, which is not 15 more than the number of customers served on day 6.

Therefore, statement A is incorrect.

B. If the number of customers continues to follow the current trend, the restaurant will make a net profit of $1,377 on day 7.

To calculate the net profit on day 7, we need to multiply the average net profit per customer ($5.82) by the number of customers on day 7:

Net profit on day 7 = $5.82 \(\times\) 237 ≈ $1,379.34

So, statement B is incorrect as the net profit on day 7 is not expected to be $1,377.

C. On day 12, the owner can expect a net profit of $1,300.

Since the question only provides information about the number of customers served for the first 6 days, we cannot determine the net profit on day 12.

Therefore, statement C is incorrect.

D. Net profit for days 6 and 7 combined is expected to be less than the earned net profit on day 1.

To calculate the net profit for days 6 and 7 combined, we need to calculate the number of customers on both days using the regression equation and then multiply it by the average net profit per customer.

Let's substitute x = 6 into the regression equation:

y = 1.03(6) + 229.4 = 6.18 + 229.4 ≈ 235.58

Now, let's calculate the net profit for days 6 and 7 combined:

Net profit on days 6 and 7 = ($5.82 \(\times\) 235) + ($5.82 \(\times\) 237) ≈ $2,735.2

Comparing this to the earned net profit on day 1, we cannot determine if it is less or greater without the information provided.

Therefore, statement D is incorrect.

In conclusion, none of the given statements are correct based on the information provided.
