The correct option is D.

Interest that compounded continuously to the principal amount. This interest rate provides exponential growth to a period of time.

Formula of continuous compound interest rate;

P(t) = P₀[tex]e^{rt}[/tex]

where P₀ is the principal amount, r is the interest rate and t is the time period.

A customer uses a store credit card to purchase a boat for $10,500.

The store credit card offers an annual interest rate, compounded continuously, of 18.99% with no payments due for the first two years.

That means,

P₀ = $10500, r = 18.99 and t = 2.

So,

P(t) = P₀[tex]e^{rt}[/tex]

Substituting the values,

P(t) = (10500)

P(t) = (10500)(1.46199)

P(t) = 15350.917

P(t) = $15350.92

Therefore, the final amount is $15350.92.

The remote interior angles of ∠1 are 34° and the right angle. The amount of m∠2 is 56°.

∠1 is an exterior angle because it is located outside the triangle. It has 2 remote interior angles. Remote interior angles are the angles with no shared vertex with the exterior angle. In this case, the remote interior angle of ∠1 is angle 34° and the right angle.

m∠1 can be measured by adding the remote interior angles:

m∠1 = 34° + 90°

m∠1 = 124°

Since m∠1 share a vertex with m∠2, then the total of both angles should be equal to 180° (a straight line). Hence:

m∠1 + m∠2 = 180°

Using the value of m∠1 known above, we can find the value of m∠2:

m∠1 + m∠2 = 180°

124° + m∠2 = 180°

m∠2 = 56°

A magnitude 8 on the Richter scale is 100 times more ground shaking than one that measures 6 on the Richter scale.

The magnitude of an earthquake is determined using the logarithm of the amplitude (height) of the largest seismic wave, calibrated to a scale by the seismometer. The Richter scale was originally developed to measure the magnitude of moderate earthquakes (magnitude 3 to magnitude 7) by assigning numbers so that the magnitude of one earthquake can be compared to another. We have, maganitude of two earthquakes, 8 and 6 Let the magnitude of first earthquake be A and second be B . So, A = 8 , B = 6 , to compare two earthquakes in terms of shaking, you subtract one magnitude from the other and raise 10 to that power, 10⁽ᴹ ⁻ ᴹ´⁾

=> 10ᴬ⁻ᴮ = 10⁸⁻⁶ = 10² = 100

So, the gradient of y = -3x^1 is -3.

The gradient of a function y = f(x) with respect to x is the derivative of the function with respect to x, denoted by dy/dx or f'(x).

In the case of y = -3x^1, the gradient is -3.

It is a constant function, thus, the slope is always the same and equal to the coefficient of the x term, which in this case is -3.

The gradient of a function tells us the rate of change of the function with respect to x. In other words, it tells us how steep the function is at any given point. A positive gradient means that the function is increasing, while a negative gradient means that the function is decreasing.

To prove the congruence between two triangles there are several postulates, that can be applied depending on the congruent parts of the triangles.

The postulates are:

SAS (Side-Angle-Side): This postulate states that if two triangles have two corresponding sides congruent and one corresponding angle congruent, we can conclude that those triangles are completely congruent.

ASA (Angle-Side-Angle): This postulate states that if two triangles have two corresponding angles congruent and one corresponding side congruent, then those triangles are congruent.

SSS (Side-Side-Side): This postulate states that if two triangles have all three corresponding sides congruent, then triangles are congruent.

AAS (Angle-Angle-Side): If two pairs of corresponding angles are congruent and one pair of corresponding sides is congruent, then both triangle are congruent each other.

HL (Hypothenuse-Leg): this postulate is applied when we have right angles. It states that two right triangles are congruent if they have one pair of corresponding leg congruent, and the hypothenuses are also congruent. We could conclude that those right triangles are congruent.

From these postulate, we can demonstrate the congruence between two triangles. Then, from that congruence, we deduct the congruence between each corresponding parts of those triangles. For example, if we demonstrate the congruence by AAS, we deduct that the third angle is also congruent, and the other two sides are also congruent.

The general form of a perfect square trinomial is (x + y)², where x and y are the roots of the trinomial. It can also be written as x² + 2xy + y² or x² + (2xy)x + y².

The general form of a perfect square trinomial is (x + y)^2, where x and y are the roots of the trinomial. To check if a trinomial is a perfect square, we can try to factor it into the square of a binomial. We can also complete the square method, which involves adding and subtracting the square of half of the x-coefficient of the linear term and then grouping the resulting terms.

It is important to note that for a trinomial to be a perfect square trinomial, the constant term must be a square of an integer and the linear term must be an even number.

Perfect square trinomials are used in solving quadratic equations and understanding their solutions, they also have applications in algebra, geometry, and trigonometry. Factoring them is a fundamental skill in algebra and is used in solving different types of mathematical problems.

The values within the range of the piecewise-defined function are

y = -6,  y = -4, y = 1 and y = 3.

A piecewise function, or f(x), is a function with various definitions at various intervals of x. A piecewise function's graph is divided into sections that each correspond to one of its definitions. A very good illustration of a piecewise function is the absolute value function.

Given f(x) = 2x + 3,   if x < -3

f(x) = x, if  x = -3

f(x) = -x - 2, if  x > -3

the function will be at x ≤ -3 and x ≥ -3

We now wish to determine which values fall within this function's range. Keep in mind that the set of possible outputs from a function constitutes its range.

The range of the first part of the function f(x) = 2*x + 2 has an upper bound at x = -3

f(-3) = 2*-3 + 2 = -6 + 2 = -4

Then the range of the first part is (-∞, -4)

Notice that the actual value -4 belongs to the range because x is smaller than and equal to -3.

The range of the second part has a lower bound for x = -3, the lower bound is:

f(-3) = -(-3) - 2 = 1

Then the range of this part is (1, ∞)

Then the range of the piecewise function is:

(-∞, -4) U (1, ∞)

and including -4 and 1

y = -6,  y = -4

y = 1,     y = 1

An angle bisector of a triangle is a line segment that divides an angle into two congruent angles. In an equilateral triangle, all angles are congruent (60 degrees), so any line segment that divides an angle into two congruent angles is also an angle bisector.

To find the angle bisector of an equilateral triangle, you can use the following method:

Draw an equilateral triangle.

Choose an angle and draw the angle bisector from the vertex of the angle to the midpoint of the opposite side.

Since all the angles of an equilateral triangle are congruent, the angle bisector that you drew bisects any angle of the triangle.

Alternatively, you can use the following method:

Draw an equilateral triangle.

Connect the midpoint of one side of the triangle to the opposite vertex.

The segment that you drew bisects the angle of the triangle.

It is important to note that in an equilateral triangle, all medians, altitudes, angle bisectors, and perpendicular bisectors are congruent, they all divide the triangle in the same ratio, so they all meet at the same point, called the centroid, which is 2/3 of the distance from each vertex to the midpoint of the opposite side.

The length of the rectangle is 74 yard.

The perimeter of a rectangle is the sum of the lengths of all four sides of the rectangle. It is calculated by adding twice the length and twice the width. The formula to calculate the perimeter of a rectangle is

P = 2(L + W), where P is the perimeter, L is the length and W is the width of the rectangle. In simpler terms, it is the total distance around the rectangle.

The perimeter of rectangle is given by  2 ( l + b)

where l is length of rectangle and b is width of the rectangle

given that perimeter of rectangle is 274

so 2 (l+b)= 274

=>  l+b= 137   ---(i)

so l = 137 -b

=> l = 137 - 63

Co-prime numbers are those numbers that have only one common factor, namely 1.

Coprimes are pair of numbers that have no common factor other than 1. There should be at least two numbers to form a set of coprimes. Such numbers have only 1 as their highest common factor, for example (4 and 7), (5, 7, 9) are co-prime numbers. It should be noted that concurrent primes need not always be primes. If the only common factor of two numbers a and b is 1, then a and b are coprimes. In this case, (a, b) is considered a prime pair. Minor primes are also referred to as relatively primes. To determine whether any two numbers are co-prime, we first find their greatest common factor (GCF). If their GCF is 1, we can say they are co-prime. Consider the two numbers 5 and 9. The factors of 5 are 1 and 5. The factors of 9 are 1, 3, and 9. The factor that is common to both 5 and 9 is 1. The GCF of (5, 9) = 1. Thus, (5 , 9) is a co-prime pair.
