Answer: B - $6,098.35

Step-by-step explanation:

This is a compound interest question. The compound interest formula is:

A = P ( 1 + r/n)^nt

A = Future amount of investment

P = Starting amount of investment

r = Rate of interest

n = Number of times interest compounds per year

t = Time (Years)

You must turn the percentage (1%) into a decimal by dividing by 100

1/100=.01

So, the equation for this question is:

A = 4,800(1+[tex]\frac{.01}{2}[/tex])^(2)(24)

A = 4800(1.005)^48

A = 4800(1.2704891611)

A = 6,098.35

{2x + y = 2

{5x + 3y - 9

Solution: We can solve this system of equations either by substitution or elimination method. Here, let's use substitution method.

From equation 1, we have: y = -2x + 2

Substituting this in equation 2, we get: 5x + 3(-2x + 2) - 9 = 0

Expanding the right-hand side, we get: 5x - 6x + 6 - 9 = 0

Simplifying further, we get: -x + (-3) = 0

Adding x to both sides, we get: -3 = x

Substituting this value of x in y = -2x + 2, we get: y = -2(-3) + 2 = 6

So, the solution to the system of equations is (x, y) = (-3, 6)

{5x - 2y = -2

{3x + 4y - 30

Solution: We can solve this system of equations by either substitution or elimination method. Here, let's use elimination method.

We can multiply equation 1 by 3 and equation 2 by 2, to make the coefficients of y same in both equations. Doing this, we get:

15x - 6y = -6

6x + 8y - 60 = 0

Adding these two equations, we get: 21x + 2y - 60 = 0

Simplifying further, we get: 21x = 60 + 2y

Dividing both sides by 21, we get: x = (60 + 2y)/21

Substituting this in equation 1, we get: 5((60 + 2y)/21) - 2y = -2

Expanding the right-hand side, we get: 60/21 + 10/21 y - 2y = -2

Simplifying further, we get: 60/21 + (-12/21) y = -2

Adding 12/21 y to both sides, we get: 60/21 = (-2) + (12/21) y

Subtracting -2 from both sides, we get: 62/21 = (12/21) y

Dividing both sides by 12/21, we get: y = 62/12 = 5 1/6

Substituting this value of y in x = (60 + 2y)/21, we get: x = (60 + 2(5 1/6))/21 = (60 + 11 1/3)/21 = (71 1/3)/21 = 71/21 + 1/63

So, the solution to the system of equations is (x, y) = (71/21 + 1/63, 5 1/6)

K'(-2, 1) is the coordinate of the image of point K, found by multiplying the original x-coordinate of the point K (2) by -1. To reflect the triangle over the y-axis, the x-coordinate of each point is multiplied by -1.

Triangle is a three-sided geometric shape which has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.

The coordinate of the image of point K is K’(-2, 1). This means that the x-coordinate of the point is -2 and the y-coordinate of the point is 1. This can be found by multiplying the original x-coordinate of the point K (2) by -1. The y-coordinate of point K remains the same, so the y-coordinate of the image of point K is 1.

Therefore, the coordinate of the image of point K is K’(-2, 1).

If the wax cost $1.38 a square foot, the cost of wax to cover the area of the floor is $1,569.75.

The correct option is B.

The total area of the floor is calculated from the shape of the floor.

The floor is made up of a trapezoid and a rectangle.

The area of a trapezoid can be calculated as:

A = (a + b)/2 * h

where

a and b are the lengths of the bases and h is the height.

The trapezoid has a height of 15 feet and bases of 35 feet and (20 - 20) or 10 feet. So its area is:

A = (35 + 10)/2 * 15

A = 337.5 square feet

The rectangle has a base of 20 feet and a height of 40 feet. So its area is:

A =20 * 40

A = 800 square feet

The total area of the figure is the sum of the areas of the trapezoid and triangle:

A = 337.5 + 800

A = 1137.5 square feet

Finally, to find the cost of the wax, we multiply the area by the cost per square foot:

Cost = 1137.5 * $1.38

Cost  = $1569.75

Answer: The line y = 3x - 5 can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, m = 3 and b = -5.

When a line is reflected across the x-axis, the slope of the line changes sign, but the y-intercept remains the same. This means that if the original line has slope m and y-intercept b, the reflected line will have slope -m and y-intercept b.

For the image, y = 1 - 3x, the slope is -3 and the y-intercept is 1.

To find the value of a, we can set the two lines equal to each other and solve for x:

3x - 5 = 1 - 3x

Solving for x, we get:

4x = 6

x = 3/2

So the line of reflection, x = a, passes through

Given a function x +4y -3 = 0

To graph the equation x + 4y - 3 = 0, we need to find at least two points that satisfy the equation and plot them on a coordinate plane. To do this, we can use the intercept method.

First, we can find the x-intercept by setting y = 0 in the equation and solving for x:

x + 4(0) - 3 = 0

x = 3

So the x-intercept is (3, 0).

Next, we can find the y-intercept by setting x = 0 in the equation and solving for y:

0 + 4y - 3 = 0

4y = 3

y = 3/4

Absolutely, because they show how big a number is, average leading zeros are regarded as significant digits. Leading zeros are counted as important figures since they help determine the decimal point's location and the size of the number.

Leading zeros in a number are important figures. This implies that when counting the total number of significant figures in a number, they are taken into account. The reason for this is that preceding zeros reveal the location of the decimal point and, hence, the size of the number. Because the leading zero signifies that the number is in hundredths, the number 0.002, for instance, has three significant figures. The number would be read as two rather than two hundredths without the leading zero. Due to their significance in assessing a number's precision, leading zeros should always be counted among the significant figures.
