Answer:

Let's start by using the formula for the perimeter of a rectangle, which is:

P = 2L + 2W

where P is the perimeter, L is the length, and W is the width.

We're given that the perimeter is 78 meters, so we can write:

78 = 2L + 2W

Simplifying this equation, we get:

39 = L + W

We're also given that the length is 6 meters less than four times the width, so we can write:

L = 4W - 6

Now we can substitute this expression for L into the equation we got earlier:

39 = (4W - 6) + W

Simplifying this equation, we get:

39 = 5W - 6

Adding 6 to both sides, we get:

45 = 5W

Dividing both sides by 5, we get:

W = 9

So the width of the rectangle is 9 meters. We can use this value to find the length:

L = 4W - 6 = 4(9) - 6 = 30

So the length of the rectangle is 30 meters.

The type of graph would have the title, "Monthly Company Profit for the Year?" is line graph (option a).

Using a line graph to display monthly company profits allows for the visualization of the overall trend and any fluctuations or changes in the profits over the year. It also allows for easy comparison of the profits from one month to another, as well as identifying which months were particularly profitable or unprofitable.

In mathematical terms, a line graph can be defined as a graph in which the data points are plotted as individual points, and a line is drawn to connect the points.

The line represents a mathematical function that can be used to model the relationship between the variables being plotted. In the case of the monthly company profits, the function would model the relationship between time and profit.

Hence the correct option (a).

The team can sell 50 half dozen boxes and 50 full dozen boxes to raise at least $1000.

We can derive an inequality from the problem statement which is:

8X + 12Y ≥ 1000

This inequality represents the amount of money the basketball team needs to raise by selling donuts.

X is the number of half dozen boxes sold

Y is the number of full dozen boxes sold.

To find a solution in terms of the given context, we can plug in different values for X and Y that satisfy the inequality. For example:

If the team sells 50 half dozen boxes and 50 full dozen boxes, they will make:

8(50) + 12(50) = $400 + $600 = $1000

So this is a valid solution that meets the fundraising goal.

If the team sells 100 half dozen boxes and 0 full dozen boxes, they will make:

8(100) + 12(0) = $800

This is not enough to meet the fundraising goal, so it is not a valid solution.

If the team sells 0 half dozen boxes and 100 full dozen boxes, they will make:

8(0) + 12(100) = $1200

This is more than the fundraising goal, so it is a valid solution, but the team may not want to sell so many full dozen boxes.

Therefore, one solution in terms of the given context is that the team can sell 50 half dozen boxes and 50 full dozen boxes to raise at least $1000.

As we have proved that if p ≡ 1 (mod 4), then -r is also a primitive root of p.

Since r is a primitive root of p, we know that every non-zero integer modulo p can be written as a power of r. That is, for any integer a with gcd(a, p) = 1, there exists an integer k such that a ≡ rˣ (mod p). This follows from the fact that the order of the element r modulo p is φ(p) = p-1, where φ denotes the Euler totient function.

Now, let us consider the case where p ≡ 1 (mod 4). This means that there exists an integer x such that p = 4x + 1. We want to show that -r is also a primitive root of p.

To do this, we first observe that (-1)² ≡ 1 (mod p) since p is an odd prime. Therefore, (-1)^(4x) ≡ 1 (mod p), which implies that (-1)²ˣ ≡ 1 (mod p).

Now, if we can show that (-1)ˣ = -1, then we will have (-1)²ˣ = (-1)ˣ*(-1)ˣ = (-1)*(-1) = 1 (mod p), which will allow us to prove that -r is also a primitive root of p.

To see that (-1)ˣ = -1, we use the fact that p ≡ 1 (mod 4) and the properties of quadratic residues. Specifically, we know that -1 is a quadratic non-residue modulo p, since if -1 ≡ a² (mod p) for some integer a, then we would have

=> [tex](-1)^{((p-1)/2) }[/tex] ≡ [tex]a^{(p-1) }[/tex]≡ 1 (mod p),

which contradicts the fact that

=> [tex](-1)^{((p-1)/2) }[/tex]= -1.

Therefore, there exists an integer b such that b² ≡ -1 (mod p).

Now, consider the product brˣ. We claim that brˣ is a primitive root of p. To see this, note that for any integer a with gcd(a, p) = 1, we can write a ≡ rˣ (mod p) for some integer k. Then, we have:

(a*brˣ)² = a² * b² * r²ˣ ≡ r²ˣ * (-1) ≡ -r²ˣ (mod p)

Since r is a primitive root of p, we know that rˣ and r²ˣ cover all the non-zero residue classes modulo p. Therefore, we can choose k such that r²ˣ ≡ -1 (mod p), which implies that (a*brˣ)² ≡ -1 (mod p).

Since a was arbitrary, this shows that brˣ is a quadratic non-residue modulo p, and therefore a primitive root of p.

The solution is : equation for the perpendicular bisector of the line segment is:  7x -2y = 6

Here, we have,

The perpendicular bisector has a slope that is the opposite of the reciprocal of the slope of the segment between the two points. It must go through the midpoint of the segment.

The latter can be found by averaging the coordinates of the end points:

 ((-5, 6) +(9, 2))/2 = ((-5+9)/2, (6+2)/2) = (2, 4)

The difference in endpoint coordinates is ...

 (Δx, Δy) = (9-(-5), 2-6) = (14, -4)

For our purpose, we're only interested in the ratio of these values, so we can divide both by the common factor of 2:

 (Δx, Δy) = (7, -2)

A line perpendicular to this segment through the point (h, k) can be written as ...

The statement that is true for the Cartesian coordinate system is A. the values below the X-axis are negative values of x.

The Cartesian coordinate system, also called rectangular coordinate system, helps plot coordinates in a two-dimensional plane. This model contains two axes -- the x-axis (horizontal) and y-axis (vertical) -- that meet at the origin. The values beneath the x-axis represent negative y-values, not x-values as some assume.

Likewise, above the x-axis represents positive y-values, not x-values. Meanwhile, points along the x-axis aren't considered either positive or negative but rather labeled based on their distance away from the origin as per this structure's guidelines.

As we have shown that matrix multiplication is associative.

Let us start by computing the products (AB) and (BC) separately. To multiply matrix A by matrix B, we need to take the dot product of each row of A with each column of B.

Simplifying the above expression, we get:

A*B = [11 -10 39] *  [21 28 13]

Similarly, to multiply matrix B by matrix C, we need to take the dot product of each row of B with each column of C. Thus, the resulting matrix (B*C) will have the same number of rows as B and the same number of columns as C. Using the given matrices B and C, we have:

B*C = [1 -2 5] * [1    -2      10]

Simplifying the above expression, we get:

B*C = [39 18]

Thus, the resulting matrix (A(BC)) will have the same number of rows as A and the same number of columns as (BC). Using the given matrices A, B, and C, we have:

A*(B*C) = [7 1] * [39  18]

Simplifying the above expression, we get:

A*(B*C) = [327 489]

Now, let us compute the product ((AB)C) by multiplying the matrix (AB) with matrix C. To do this, we need to take the dot product of each row of (AB) with the only column of C. Thus, the resulting matrix ((A*B)C) will have the same number of rows as (AB) and the same number of columns as C. Using the given matrices A, B, and C, we have:

(A*B)*C = [11 -10 39] * [1      -2       10]

Simplifying the above expression, we get:

(A*B)*C = [327     489]

As we can see from the above calculations, both the products (A*(BC)) and ((AB)*C) have the same result, which is [327 489]. Therefore, we can conclude that matrix multiplication is associative.
