What is compound interest?

Compound interest is a type of financial phenomenon in which interest you earn in a savings or investment account earns interest of its own over time. It is also said that Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest

the given parameters to help solve the question are

Amount = R50,000

Interest rate = 8%

Time = 25years compounded quarterly

The formula for compound interest compounded quarterly is

A= P × (1 + R/(4 × 100))⁴ⁿ,

where P is the principal and R is the interest rate

50000 = R[1+0.08]⁴*³

50000 = R[1.08)¹²

R= 50000/1.08¹²

According to the given information, the one angle on the straight line inside a circle is 135 then the value of the x = 4 as both angles are supplementary angles.

Supplementary angles are two angles whose sum is 180 degrees. In other words, if we add the measures of two supplementary angles, the result is always 180 degrees.

When two lines intersect, they form four angles at the intersection point. If two of these angles are supplementary, they are called adjacent supplementary angles. In this case, they share a common side and a common vertex, and their non-shared sides form a straight line.

For example, if angle A and angle B are adjacent angles, and angle A measures 120 degrees, then angle B must measure 60 degrees, since 120 + 60 = 180.

If the two angles are on a straight line, then they are supplementary, meaning their sum is 180 degrees. Therefore, we can set up the equation:

135 + (11x + 1) = 180

Simplifying the left side, we get:

136 + 11x = 180

Subtracting 136 from both sides, we get:

11x = 44

Dividing both sides by 11, we get:

x = 4

Therefore, the value of x is 4.

Sample Response: Bobby’s interquartile range is 113, while Amelia’s is 179. A lower interquartile range means Bobby’s scores are closer to the median.

I cannot agree or disagree with personal beliefs. However, based on statistical principles, if the range of Bobby's scores is narrower than Amelia's range, then it is likely that Bobby's scores are closer to his median. Alternatively, if Amelia's scores are spread out more, her median may not be a good representation of the typical score, and her scores may not cluster closely around it. Ultimately, without more information on the distribution of the scores, it is impossible to determine who has scores clustered closer to their median.

The derivative of the function y =  ((2x - 1)³)/√(3x + 1)​ is dy/dx = (2x - 1)²[3x + 6]/(2[√(3x + 1)]³)

The derivative of a function is the limit as the change in x tnds to zero of the change in y over the change in x.

To find the derivative of the function y =  ((2x - 1)³)/√(3x + 1)​, we use the quotient rule.

dy/dx = (vdu/dx - udv/dx)/v²

where u = (2x - 1)³ and v = √(3x + 1)

So, du/dx = 3(2x - 1)² and dv/dx = 3/[2√(3x + 1)]

Substituting the values of the variables into the equation, we have that

dy/dx = (vdu/dx - udv/dx)/v²

dy/dx = (√(3x + 1) × 3(2x - 1)²  -  (2x - 1)³ × 3/[2√(3x + 1)])/[√(3x + 1)]²

dy/dx = (3√(3x + 1)(2x - 1)²  -  3(2x - 1)³/[2√(3x + 1)])/[√(3x + 1)]²

= (3√(3x + 1)√(3x + 1)(2x - 1)²  -  3(2x - 1)³/[2√(3x + 1)])(3x + 1)²

= [3(3x + 1)(2x - 1)²  -  3(2x - 1)³/[2√(3x + 1)])(3x + 1)²

= (2x - 1)²[3(3x + 1)  -  3(2x - 1)/[2√(3x + 1)])(3x + 1)²

= (2x - 1)²[9x + 3  -  6x + 3]/[2√(3x + 1)])(3x + 1)²

= (2x - 1)²[3x + 6]/(2[√(3x + 1)]³)

So, dy/dx = (2x - 1)²[3x + 6]/(2[√(3x + 1)]³)

The solution of Unit Problem is Solution of first part is As the contribution margin is positive, accepting the special sales order would be profitable for Hobby-Cardz,and second part is  total profit is negative

Contribution margin is the difference between a product's revenue and its variable costs. It represents the amount of money that is available to cover fixed costs and contribute to profit.

1)Incremental Analysis without special order:

Revenue from 51,000 packs at $0.43 per pack = $21,930

Total variable costs for 51,000 packs = 51,000 x $0.33 = $16,830

Contribution margin = $21,930 - $16,830 = $5,100

As the contribution margin is positive, accepting the special sales order would be profitable for Hobby-Cardz.

2)Incremental Analysis with special hologram baseball cards:

In addition to the incremental analysis performed in Part 1, we need to consider the additional cost of $5,300 to develop the hologram.

Revenue from 51,000 packs at $0.43 per pack = $21,930

Total variable costs for 51,000 packs = 51,000 x $0.33 = $16,830

Contribution margin = $21,930 - $16,830 = $5,100

Less: Additional cost of hologram development = $5,300

Total profit/loss = $5,100 - $5,300 = ($200)

As the total profit is negative, accepting the special sales order with the hologram development cost would result in a loss of $200. Therefore, Hobby-Cardz should not accept the special order under these circumstances.

Answer:

We need to subtract 41/6 from 53/6 to get 8. Alternatively, we can say that 8 is 41/6 less than 53/6.

Step-by-step explanation:

To determine how much to subtract from 53/6 to make 8, we need to perform the following calculation:

53/6 - x = 8

where x is the amount we need to subtract.

To isolate x, we need to isolate it on one side of the equation. We can do this by subtracting 53/6 from both sides:

53/6 - x - 53/6 = 8 - 53/6

Simplifying the left-hand side gives:

-x = 8 - 53/6 + 53/6

Simplifying the right-hand side gives:

-x = 41/6

Multiplying both sides by -1 gives:

x = -41/6

Therefore, we need to subtract 41/6 from 53/6 to get 8. Alternatively, we can say that 8 is 41/6 less than 53/6.

Answer:

The dimensions of the rectangle are approximately 8.54 units by 3.54 units.

Step-by-step explanation:

Let's start by using algebra to represent the information given in the problem.

Let L be the length of the rectangle.

Then, the width of the rectangle is 5 units less than the length, which means the width can be expressed as L - 5.

The area of a rectangle is given by the formula A = L * W, where A is the area, L is the length, and W is the width. In this case, we are given that the area is 36 square units. So we can write:

A = L * (L - 5)

36 = L * (L - 5)

Expanding the right-hand side of the equation, we get:

36 = L^2 - 5L

Moving all the terms to the left-hand side of the equation, we get:

L^2 - 5L - 36 = 0

Now we can use the quadratic formula to solve for L:

L = (-(-5) ± sqrt((-5)^2 - 4(1)(-36))) / (2(1))

Simplifying this expression, we get:

L = (5 ± sqrt(229)) / 2

We can discard the negative solution since the length of a rectangle cannot be negative.

So, the length of the rectangle is approximately 8.54 units (rounded to two decimal places).

To find the width, we can substitute this value of L into the expression we derived earlier for the width:

W = L - 5

W = 8.54 - 5

W ≈ 3.54 units (rounded to two decimal places)

Therefore, the dimensions of the rectangle are approximately 8.54 units by 3.54 units.

To find the volume of an irregular 3D shape like Myron's pool, he needs to determine:

The change referred to in the headline is an absolute change. An absolute change is a difference or increase in a quantity that is measured without reference to the original or initial value.

In this case, the headline states that enrollments at Northeastern University are expected to increase by 1,700 students. This means that the actual number of students is expected to increase by 1,700 from its current or previous level, without any reference to the original number of students enrolled at Northeastern University.

An absolute change is usually expressed in units of the quantity being measured, such as students, dollars, or meters. In contrast, a relative change is expressed as a percentage or ratio of the original or initial value. A relative change indicates how much a quantity has changed in proportion to its initial value.

For example, if enrollments at Northeastern University were expected to increase by 10%, this would be a relative change because it represents a percentage of the current or previous level of enrollment.

The altitude of the plane is approximately 21.65 miles.

An altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex).

We have an observer on the ground (you) and a plane flying towards you. Let's call the distance between the observer and the point directly below the plane "x", and let's call the altitude of the plane "h".

At the first moment, the angle between the ground and your line of sight to the plane is 45 degrees. This means that the angle between the plane's altitude and the ground is also 45 degrees (since the plane is flying horizontally towards you). We can use trigonometry to find the value of "x" in terms of "h".

In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:

tan(45) = h/x

Since tan(45) = 1, we can simplify this to:

h/x = 1

h = x

So the distance between the observer and the point directly below the plane is equal to the altitude of the plane.

One minute later, the angle between the ground and your line of sight to the plane is 60 degrees. We can use the same approach to find the new value of "x" in terms of "h".

In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:

tan(60) = h/(x + 450/60)

Simplifying this, we get:

h = (x + 7.5h) * sqrt(3)

Solving for "x", we get:

x = (h / sqrt(3)) - 7.5h

Now we can substitute the value of "x" from the first moment (which is equal to the altitude of the plane) into this equation to find the altitude of the plane:

h = (h / sqrt(3)) - 7.5h

h = h(1 / sqrt(3) - 7.5)

h = 21.65 miles (rounded to two decimal places)

Therefore, the altitude of the plane is approximately 21.65 miles.
