True or False? A circle could be circumscribed about the quadrilateral below.

Answer:

Trevor must score a 73.

We will create an equation that has four values (three knowns, one unknown) that will divide by 4 to find the average.

Our equation will look like this:

[tex]\displaystyle \frac{86+83+78+x}{4}=80[/tex]

First, combine all like terms.

[tex]\displaystyle \frac{247+x}{4}=80[/tex]

Then, divide the fraction.

[tex]\displaystyle \frac{247}{4} + \frac{x}{4} = 80[/tex]

Subtract 247/4 from both sides of the equation.

[tex]\displaystyle \frac{247}{4} - \frac{247}{4} + \frac{x}{4} = 80 - \frac{247}{4}[/tex]

[tex]\displaystyle \frac{x}{4} = \frac{73}{4}[/tex]

Then, multiply both sides of the equation by 4 to get rid of the denominator and isolate the variable.

[tex]4\times\displaystyle \frac{x}{4} = 4\times\frac{73}{4}[/tex]

[tex]x=73[/tex]

[tex]\boxed{\bold{x=73}}[/tex]

Answer:

(r o q)(-1) = 20

(q o r)(-1) = -11

Step-by-step explanation:

Given

[tex]q(x) = -2x + 1[/tex]

[tex]r(x) = 2x^2 + 2[/tex]

Solving (a): (r o q)(-1)

In function:

(r o q)(x) = r(q(x))

So, first we calculate q(-1)

[tex]q(x) = -2x + 1[/tex]

[tex]q(-1) = -2(-1) + 1[/tex]

[tex]q(-1) = 2 + 1[/tex]

[tex]q(-1) = 3[/tex]

Next, we calculate r(q(-1))

Substitute 3 for q(-1)in r(q(-1))

r(q(-1)) = r(3)

This gives:

[tex]r(x) = 2x^2 + 2[/tex]

[tex]r(3) = 2(3)^2 + 2[/tex]

[tex]r(-1) = 2*9 + 2[/tex]

[tex]r(-1) = 20[/tex]

Hence:

(r o q)(-1) = 20

Solving (b): (q o r)(-1)

So, first we calculate r(-1)

[tex]r(x) = 2x^2 + 2[/tex]

[tex]r(-1) = 2(-1)^2 + 2[/tex]

[tex]r(-1) = 2*1 + 2[/tex]

[tex]r(-1) = 6\\[/tex]

Next, we calculate r(q(-1))

Substitute 6 for r(-1)in q(r(-1))

q(r(-1)) = q(6)

[tex]q(x) = -2x + 1[/tex]

[tex]q(6) = -2(6) + 1[/tex]

[tex]q(6) =- 12 + 1[/tex]

[tex]q(6) = -11[/tex]

Hence:

(q o r)(-1) = -11

Answer:

[tex]z - 0.05z = 236.60[/tex]

Step-by-step explanation:

Given

[tex]Discount = 5\%[/tex]

[tex]Total\ Cost = 236.60[/tex]

Represent the cost of goods bought with z

When the coupon is applied, the discount becomes

[tex]Discount = 5\% * z[/tex]

This gives:

[tex]Discount = 0.05 * z[/tex]

[tex]Discount = 0.05z[/tex]

The discount subtracted from the cost of good will gives the total amount paid.

So, we have:

[tex]Cost\ of\ Goods - Discount = Total\ Cost[/tex]

This gives:

[tex]z - 0.05z = 236.60[/tex]

Hence, option (a) is correct

The maximum revenue obtained for the given revenue function is 43340.

Maxima and minima are the highest and lowest values of a function within a given set of ranges.

Now, as per the given question;

The given revenue function is;  R(x) = 395x − 0.9x²

Differentiate the given function with respect to x.

dR/dx = 395 − 2×0.9x

dR/dx = 395 - 1.8x

Put the given equation equal to zero and find the critical point for which the function will become maximum.

395 - 1.8x = 0

x = 219.44

x ≈≈ 220.

Substitute the obtained value of x in the revenue function to find its maximum value.

R(x) = 395x − 0.9x²

R(220) = 395×220 − 0.9(220)²

R(220) = 86900 - 43560

R(220) = 43340.

Therefore, the maximum revenue calculated for the given revenue function is 43340.

An equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept.

Given the line

6x+y=2

Simplifying the equation to write into the  slope-intercept form

y = -6x+2

So, the slope = -6

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus, the slope of the perpendicular line will be: -1/-6 = 1/6

Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1/6 and the point (6, -2)

[tex]y-\left(-2\right)=\frac{1}{6}\left(x-6\right)[/tex]

[tex]y+2=\frac{1}{6}\left(x-6\right)[/tex]

subtract 2 from both sides

[tex]y+2-2=\frac{1}{6}\left(x-6\right)-2[/tex]

[tex]y=\frac{1}{6}x-3[/tex]

Therefore, an equation of the line that passes through the point (6, − 2) and is perpendicular to the line will be:

Answer:

Step-by-step explanation:

Angle 3 and angle 6 are congruent because they are alternate interior angles. Angle 3 plus angle 1 is 180 degrees. So you just subtract 123 from 180 (180-123) and you get 57 degrees.

The measure of angle 6 is 57°

The correct answer is an option (A)

"The lines in the same plane that are at equal distance from each other and never meet."

"A line that passes through two lines in the same plane at two distinct points in the geometry. "

"The angles directly opposite to each other when two lines intersect in a plane."

For given question,

Line n and line p are parallel lines and line t is the transversal.

Here, angle 1 and angle 4 are opposite angles.

⇒ ∠1 = ∠4

We have been given that ∠1 = 123°

⇒ ∠4 = 123°

Also, angle 4 and angle 6 are interior angles on the same side of the transversal.

We know that each pair of interior angles on the same side of the transversal is supplementary.

⇒ ∠4 + ∠6 = 180°

⇒ 123° + ∠6 = 180°

⇒ ∠6 = 180° - 123°

⇒ ∠6 = 57°

Therefore, the measure of angle 6 is 57°

The correct answer is an option (A)
