What is trapezoid?

A trapezoid, commonly referred to as a trapezium, is a quadrilateral or polygon with four sides. It has a set of parallel opposite sides as well as a set of non-parallel sides. The bases and legs of the trapezoid are referred to as parallel and non-parallel sides, respectively. A trapezoid is a four-sided closed 2D figure with a perimeter and an area. The bases of the trapezoid are two of the shape's sides that are parallel to one another. The legs or lateral sides of a trapezoid are its non-parallel sides. The altitude is the shortest distance between any two parallel sides.

Here the parallel sides are given 12m and 20m.

The perpendicular line will be the fence

so the other line is given 17m.

The area of the trapezoid is (a+b/2)*h

h =√17²-8² =15

So the area will be 12+20/2 * 15

A= 16*15 = 240m²

For 100 m² cost 19.75

For 240 it will be 19.75/100 * 240= 47.4

Hence the total money will be spent is 47.4 ∈.

The intersection of sets A and B

The intersection of two sets is the set of elements that are common to both sets. To find the intersection of sets A and B, we simply look for the elements that are in both sets. In this case, the intersection of A and B is {h, o, e}.

The union of two sets is the set of elements that are in either one of the sets or both. To find the union of sets A and B, we simply combine the elements from both sets, making sure to not include any duplicates. In this case, the union of A and B is {h, o, m, e, u, s}.

So, the intersection of sets A and B is {h, o, e} and the union of sets A and B is {h, o, m, e, u, s}.

The total amount of interest on the investment if compounded continuously comes out to be $10064.60, rounded off to the nearest dollar and cent.

To find the total amount of money accumulated for an initial investment of $5200 at 6% compounded quarterly after 11 years, we can use the formula A = P(1+r/n)^(nt), where A is the total amount, P is the principal or initial investment, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. Plugging in the given values, we get:

A = 5200(1+0.06/4)^(4*11)
A = 5200(1.015)^44
A = 5200*1.9878
A = $10336.96

Therefore, the total amount of money accumulated after 11 years is $10336.96, rounded off to the nearest dollar and cent.

To compute the total amount of interest on the investment if compounded continuously, we can use the formula A= P e^(rt), where e is the base of the natural logarithm. Plugging in the given values, we get:

A = 5200 e^(0.06*11)
A = 5200 e^0.66
A = 5200*1.9355
A = $10064.60

The exact value of the distance between L1 and L2 is 131 / √221. Enter this value in the box.

The distance between two parallel lines can be found by taking the distance between a point on one line and the other line. We can use point C and line L1 to find the distance between the two lines.

First, we need to find the direction vector of line L1. The direction vector can be found by subtracting the coordinates of point A from point B:

u = B - A = (-6,-4,3) - (8,1,3) = (-14,-5,0)

Next, we need to find the vector between point C and point A:

v = C - A = (9,-8,3) - (8,1,3) = (1,-9,0)

Now, we can find the distance between point C and line L1 by taking the cross product of u and v and dividing by the magnitude of u:

w = u x v = (-5*0 - 0*(-9), 0*0 - (-14*0), -14*(-9) - (-5*1)) = (0,0,131)

||w|| = √(0^2 + 0^2 + 131^2) = 131

||u|| = √((-14)^2 + (-5)^2 + 0^2) = √221

distance = ||w|| / ||u|| = 131 / √221

Therefore, the distance between L1 and L2 is 131 / √221.

The exact value of the distance between L1 and L2 is 131 / √221. Enter this value in the box.

The solution to the exponential equation is given as follows:

x = 4.

The equation for this problem is defined as follows:

4^(2x+4) = 16^(3x-6).

Looking at the left-side of the equality, we can apply the power of power property, as 16 = 4², hence:

16^(3x-6) = 4^[2(3x - 6)] = 4^(6x - 12)

(the power of power property means that we keep the base then multiply the powers relative to the same base).

Hence the equation can be written as follows, considering the simplification to the right side of the equality.

4^(2x+4) = 4^(6x - 12)

Answer:

1st page:

To determine if Jason and Arianna made a mistake in their solution, we can examine the slopes and y-intercepts of the two equations.

The first equation, 5x - 3y = -1, can be written in slope-intercept form as y = (5/3)x + 1/3, where the slope is 5/3 and the y-intercept is 1/3.

The second equation, 3x + 2y = 7, can be written in slope-intercept form as y = (-3/2)x + 7/2, where the slope is -3/2 and the y-intercept is 7/2.

To solve the system of equations, we need to find the point of intersection of the two lines. We can see from the slopes that the lines are not parallel, so they must intersect at some point. However, the slopes are not perpendicular either, so they do not intersect at a right angle.

By graphing the two equations on the same coordinate plane, we can see that the point of intersection is (2, 2), not (4.04, 7.31) as Jason and Arianna calculated. Therefore, they must have made a mistake in their solution.

In summary, we can tell that Jason and Arianna made a mistake in their solution by examining the slopes and y-intercepts of the two equations and graphing them to find the actual point of intersection.

2nd page:

To determine if Jason and Arianna made a mistake in their solution, we can graph the two linear equations on the same coordinate plane and look for the point of intersection.

We can begin by rearranging the equations into slope-intercept form:

5x - 3y = -1 → y = (5/3)x + 1/3

3x + 2y = 7 → y = (-3/2)x + 7/2

Now we can graph the two lines. We can plot two points for each line and connect them with a straight line to obtain the graphs.

For the first equation, when x = 0, we get y = 1/3. When x = 3, we get y = 6/3 = 2. Plotting these two points and connecting them, we get:

Graph of the first equation

For the second equation, when x = 0, we get y = 7/2. When x = 2, we get y = 1/2. Plotting these two points and connecting them, we get:

Graph of the second equation

We can see from the graphs that the lines intersect at the point (2, 2), not at (4.04, 7.31) as Jason and Arianna found. Therefore, they must have made a mistake in their solution.

In summary, we can tell from the graphs of the equations that Jason and Arianna must have made a mistake because the lines do not intersect at the point they found.

3rd page:

We can determine if there is a unique solution to the system of linear equations by examining the slopes of the two equations.

The slope of the first equation, 5x - 3y = -1, can be found by rearranging the equation into slope-intercept form y = (5/3)x + 1/3. We can see that the slope of the line is positive and not equal to the slope of the second equation, which is -3/2.

Similarly, the slope of the second equation, 3x + 2y = 7, can be found by rearranging the equation into slope-intercept form y = (-3/2)x + 7/2. Again, we can see that the slope of the line is negative and not equal to the slope of the first equation, which is 5/3.

Since the slopes of the two lines are not equal, they will intersect at a unique point. In other words, there is only one solution to the system of equations.

Therefore, we can conclude that there is a unique solution to the system of linear equations given by 5x - 3y = -1 and 3x + 2y = 7, based on the slopes of the graphs of the equations in the system.

Answer:

Therefore, the lower fence is 1.5 and the upper fence is 5.5.

Step-by-step explanation:

To determine the upper and lower fences for a boxplot, we first need to calculate the interquartile range (IQR), which is the difference between the third quartile (Q3) and the first quartile (Q1). Then, we can use the following formulas:

Lower Fence = Q1 - 1.5 * IQR

Upper Fence = Q3 + 1.5 * IQR

In the given boxplot, the box extends from 2 to 5, with the median (Q2) at 3.5. The first quartile (Q1) is 3 and the third quartile (Q3) is 4. Therefore, the IQR is:

IQR = Q3 - Q1 = 4 - 3 = 1

Using the formulas above, we can calculate the lower and upper fences:

Lower Fence = Q1 - 1.5 * IQR = 3 - 1.5 * 1 = 1.5

Upper Fence = Q3 + 1.5 * IQR = 4 + 1.5 * 1 = 5.5

Therefore, the lower fence is 1.5 and the upper fence is 5.5.
