Answer:

c = -a/4 + b + 11/4

Step-by-step explanation:

Solve for c:

a = -4 c + 4 b + 11

a = -4 c + 4 b + 11 is equivalent to -4 c + 4 b + 11 = a:

-4 c + 4 b + 11 = a

Subtract 4 b + 11 from both sides:

-4 c = a + (-4 b - 11)

Divide both sides by -4:

Answer:  c = -a/4 + b + 11/4

The product of the functions f(x) and g(x), where the functions f(x) = [tex]x+2[/tex] and g(x) = [tex]-x^{2}[/tex] is

As per the given question statement, we are supposed to find and simplify the product of the functions f(x) and g(x), where the functions f(x) = [tex]x+2[/tex]and g(x) = [tex]-x^{2}[/tex].

Let's assume [tex]m(x)[/tex] be the product of the functions [tex]f(x)[/tex] and [tex]g(x)[/tex]

So, [tex]m(x) = f(x) * g(x)\\m(x)= (x+2)*(-x^{2} )\\m(x)=-x^{3} -2x^{2}[/tex]

Therefore the product of the functions f(x) and g(x), where the functions f(x) = [tex]x+2[/tex]and g(x) = [tex]-x^{2}[/tex] is [tex]m(x)=-x^{3} -2x^{2}[/tex]

Answer:

Step-by-step explanation:

Given vertices:

As points A and B, and points C and D, have the same y-coordinates, AB is parallel to CD.

As there is a difference of 5 units between points A and B, and C and D, AB = CD.

As AB is parallel to CD and AB = CD ⇒ AD = BD and AD is parallel to BD.

Therefore, the quadrilateral ABCD is a parallelogram (see attachment).

To find the perimeter of ABCD, calculate the side lengths of AB and AD using the Distance Formula.

[tex]\boxed{\begin{minipage}{4.7 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}AB & =\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& =\sqrt{(10-5)^2+(-3-(-3))^2}\\& =\sqrt{(5)^2+(0)^2}\\& =\sqrt{25}\\& =5\:\:\sf units\end{aligned}[/tex]

[tex]\begin{aligned}AD & =\sqrt{(x_D-x_A)^2+(y_D-y_A)^2}\\& =\sqrt{(7-5)^2+(-11-(-3))^2}\\& =\sqrt{(2)^2+(-8)^2}\\& =\sqrt{4+64}\\& =\sqrt{68}\:\:\sf units\end{aligned}[/tex]

The perimeter of a two-dimensional shape is the distance all the way around the outside.

[tex]\begin{aligned}\textsf{Perimeter of $ABCD$} & = AB + CD + AD + BC\\& = 2\:AB + 2\:AD\\& = 2 \cdot 5+2 \cdot \sqrt{68}\\& = 10+2 \sqrt{68}\\& = 10+2\sqrt{4 \cdot 17}\\& = 10+2\sqrt{4}\sqrt{17}\\& = 10+2 \cdot2\sqrt{17}\\& = 10+4\sqrt{17}\:\:\sf units\end{aligned}[/tex]

As 1 unit = 1 meter, the perimeter of the fence is (10 + 4√17) m.

If fencing costs $200 per meter:

[tex]\begin{aligned}\sf \implies Cost \:of\:fencing& = 200(10 + 4 \sqrt{17})\\& = 2000+800 \sqrt{17}\\& = 5298.4845\\ & = \$5298.48\end{aligned}[/tex]

to get an average, you add up all the factors then divide them by how many there are. I added 500 12 times to 1250 12 times to 1150 3 times and 600 4 times.

aka (500*12)+(1250*12)+1150+1150+1150+600+600+600

then i divided by 31 because 12+12+3+4=31. giving the average $866.13.

The function notation of the coordinate point where the coordinate point is given as (-5, 18) is f(-5) = 18

Coordinate points are mathematical statements that are used to represent the location of points on a coordinate plane

The coordinate point is given as

(-5, 18)

The above coordinate point can be represented as

(x, y) = (-5, 18)

The above coordinate point can further be rewritten as

(x, f(x)) = (-5, 18)

So, we have

x = -5

f(x) = 18

Substitute x = -5 in the equation f(x) = 18

f(-5) = 18

Hence, the function notation of the coordinate point where the coordinate point is given as (-5, 18) is f(-5) = 18

Answer: can u finish the question

Step-by-step explanation:

Applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.

The linear pair theorem states that when two angles form a linear pair, the sum of both angles of the linear pair would be equal to 180 degrees.

Two angles that are a vertical pair, have a measure that is equal to each other, based on the vertical angles theorem. That is, they are congruent angles.

m<RQS + m<PQT = 180 degrees [linear pair theorem]

Substitute

(2m + 4)° + (3m + 1)° = 180°

Solve of the value of m

2m + 4 + 3m + 1 = 180

Add like terms together

2m + 3m + 4 + 1 = 180

5m + 5 = 180

5m + 5 - 5 = 180 - 5

5m = 175

5m/5 = 175/5

m = 35

m<PQR = 3m + 1 [vertical angles theorem]

Plug in the value of m

m<PQR = 3(35) + 1

m<PQR = 105 + 1

m<PQR = 106°

m<PQV = 1/2(m<PQR)

m<PQV = 1/2(106)

m<PQV = 53°

Thus, applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.

The coordinates of the resulting point after the reflection are (-5, -5)

When we do a reflection over a given line, the perpendicular distancee between the line and the point is invariant.

In this case, we want to reflect the point (-5, -1) over the line y = -3

The distance between the y-value of the point and the line is:

D = |-1 - (-3)| = | -1 + 3| = 2

The point is at 2 units (above) from the line, then after the reflection, the point will be 2 units below the line.

So the new y-value is:

y = -3 - D = -3 - 2 = -5

The coordinates of the resulting point are (-5, -5).

The mean absolute deviation is 5.4.

The mean absolute deviation tells us that the variance of each data set is 5.4.

The mean absolute deviation is a measure of variance that determines the average distance between each data point in the dataset and its mean.

The mean absolute deviation = 1/n ∑ l x - m(x) l

The first step is to determine the mean of the data set: (18 + 15 + 25 + 17 + 13 + 15 +  23 + 27 + 30 +  27) / 10

= 210 / 10

= 21

The second step is to determine the absolute difference between the mean and each data point. Then add the result together.

|(18 - 21) + (15 - 21)+ (25- 21) + (17- 21) + (13- 21) + (15- 21) +  (23- 21) + (27- 21) + (30- 21) +  (27- 21)| = 54

Now, divide the sum by the total numbers in the data set : 54 / 10 = 5.4
