The expression that could result in a final unit measure of dollars is given by (mnk²) dollars.

To write an expression that could result in a final unit measure of dollars, we need to consider the units given.

We have three units, i.e., m feet, n feet, and k dollars per square foot.

To convert these units to dollars, we need to multiply the given units with appropriate conversion factors.

The conversion factor for the given units is as follows:

Unit 1: 1 foot = k dollars (Conversion factor)

Unit 2: 1 foot = k dollars (Conversion factor)

Unit 3: 1 square foot = 1 x k dollars = k dollars (Conversion factor)

Now, let us write the expression that results in a final unit measure of dollars.

The expression should be written in HTML format.

Let us begin: Final Unit Measure = (Unit 1) x (Unit 2) x (Unit 3)

Final Unit Measure = (m feet) x (n feet) x (k dollars per square foot)

Final Unit Measure = m x k dollars x n x k dollars per square foot

Final Unit Measure = (m x k x n x k) dollars

Final Unit Measure = (mnk²) dollars.

Thus, the expression that could result in a final unit measure of dollars is given by (mnk²) dollars.

As per the concept of confidence interval, we can be 90% confident that the true proportion of red candies in all the bags is between 0.195 and 0.285.

To do this, we first need to determine the level of confidence we want for our interval.

Next, we use a formula to calculate the confidence interval. The formula for a confidence interval for a population proportion is:

p ± z x √(p(1-p)/n)

where p is the sample proportion (in this case, 120/500 = 0.24), z* is the z-score that corresponds to the desired level of confidence (for a 90% confidence interval, z* = 1.645), and n is the sample size (in this case, 500).

Substituting the values into the formula, we get:

0.24 ± 1.645 x √(0.24(1-0.24)/500)

Simplifying, we get:

0.24 ± 0.045

Therefore, the lower limit of the confidence interval is 0.195 (0.24 - 0.045), and the upper limit is 0.285 (0.24 + 0.045).

The altitude of the plane at the George Washington Bridge is approximately 0.2095 miles (or 1,106 feet) above sea level, plus whatever the height of the bridge is.

Altitude refers to the height of an object or location above a specific reference point, usually the Earth's sea level. In aviation, altitude is often used to describe the height of an aircraft above sea level, and is measured in feet or meters.

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It involves the study of trigonometric functions, which are functions of an angle, and are used to relate the angles and sides of a right triangle.

In the given question,

To solve this problem, we need to use trigonometry and the fact that the plane descended at a 2° angle. Let's assume that the altitude of the plane at the George Washington Bridge is h feet.

Using trigonometry, we know that the tangent of the angle of descent is equal to the difference in altitude divided by the horizontal distance traveled. In this case, we have:

tan(2°) = (h - e) / 6

To solve for h, we need to isolate it on one side of the equation. Multiplying both sides by 6, we get:

6 tan(2°) = h - e

Adding e to both sides, we get:

h = 6 tan(2°) + e

We can use a calculator to find the tangent of 2°, which is approximately 0.03492. Substituting this value and the given distance of 6 miles into the equation, we get:

h = 6(0.03492) + e

h = 0.2095 + e

Therefore, the altitude of the plane at the George Washington Bridge is approximately 0.2095 miles (or 1,106 feet) above sea level, plus whatever the height of the bridge is.

The present value that must be invested to get $2500 after 6 years at a simple interest rate of 11.0% is $1509.64.

In this case, we know the final amount that we want to have after 6 years, which is $2500. We also know the interest rate, which is 11.0%. What we need to find is the principal amount, which is the present value that we must invest now to achieve the desired future value.

Using the formula for simple interest, we can rearrange it to solve for the principal:

Principal = Simple Interest / (Rate x Time)

We know that the simple interest is the difference between the final amount and the principal amount. Therefore, we can substitute the values into the formula:

$2500 - Principal = (Principal x 0.11 x 6)

Simplifying the equation, we get:

$2500 = Principal + (0.66 x Principal)

$2500 = 1.66 x Principal

Dividing both sides by 1.66, we get:

Principal = $1509.64

General solution = CF + PS= c₁ cos 5x + c₂ sin 5x - (2/25) tan 5x= C sin (5x) + D cos (5x) - (2/25) ln(sec(5x) + tan(5x)), where C = c₂ and D = c₁.

Explanation:

The general solution of the given non-homogeneous differential equation: y"(x) + 25y(x) = 2tan 5x isy (x) = C sin (5x) + D cos (5x) - (2/25) ln(sec(5x) + tan(5x)).

First of all, we need to find the complementary function(CF) of the differential equation to find the general solution.To find the complementary function (CF),

we set the non-homogeneous term to 0.y" (x) + 25y (x) = 0T

his is a homogeneous differential equation with the characteristic equation: r² + 25 = 0Solving this quadratic equation gives:r = ± 5i

Hence, the complementary function is given by:CF = c₁ cos 5x + c₂ sin 5xwhere c₁ and c₂ are constants of integration.

Now, we find the particular solution (PS) of the given non-homogeneous differential equation using the method of undetermined coefficients.

Given, y" (x) + 25 y (x) = 2 tan 5x

For PS, we assume that y = A tan 5x + B

where A and B are constants to be determined.Substituting this in the given equation, we get:10A sec² 5x + 25(A tan 5x + B) = 2 tan 5x

Simplifying this equation, we get:10A sec² 5x + 25A tan 5x + 25B = 2 tan 5x⇒ 10A sec² 5x + 23A tan 5x + 25B = 0

Comparing the coefficients of tan 5x and sec² 5x on both sides, we get:A = -2/25 and B = 0

Hence, the particular solution is given by:PS = - (2/25) tan 5xNow, the general solution of the given non-homogeneous differential equation is given by

:GS = CF + PS= c₁ cos 5x + c₂ sin 5x - (2/25) tan 5x= C sin (5x) + D cos (5x) - (2/25) ln(sec(5x) + tan(5x)), where C = c₂ and D = c₁.

Answer:

Step-by-step explanation:

We can use the simple interest formula to solve this problem. The formula is:

I = P * r * t

Where:

I = Interest earned

P = Principal (initial amount of money)

r = Interest rate per year (as a decimal)

t = Time (in years)

From the problem statement, we know that:

I = $80.00

r = 0.04 (4% as a decimal)

t = 8 years

Substituting these values into the formula, we get:

$80.00 = P * 0.04 * 8

Simplifying:

$80.00 = 0.32P

Dividing both sides by 0.32, we get:

P = $250.00

Therefore, the principal is $250.00.

The radius of the sphere with a volume of 4,500π cubic inches is 15 inches, not 2,000 inches as the student had incorrectly calculated.

What is volume?

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

The volume of the sphere is given as 4,500π cubic inches.

The formula for volume of the sphere is -

V= 4/3πr³

Substituting the values in the equation -

4,500π = 4/3πr³

4,500 = 4/3r³

The mistake in the student's calculation is in the step where they simplified 4/3πr³ to 4,500.

To correct this, we need to isolate r³ by dividing both sides by 4/3 -

4,500 = (4/3)r³

4,500 ÷ (4/3) = r³

4,500 × 3/4 = r³

3,375 = r³

Then, we can take the cube root of both sides to find r -

r = ∛3,375 = 15
