Answer:

875 yearbooks.

Step-by-step explanation:

To maximize profit, at $8125 prices should the school charge for the yearbooks

Simplify first the equation,

R(x) = 25000 - 2500x + 6250x - 625x²

Then, we differentiate the equation and equate to zero.

dR(x) = -2500 + 6250 - 1250x = 0

The value of x from the equation is 3.

(1) The price is equal to 50 - 5(3) = $35.

(2) The possible maximum revenue:

R(x) = 2500 - 2500(3) + 6250(3) - 625(3²) = $8125

(3) number of yearbooks sold:

500 + 125(3) = 875 yearbooks

Answer:

y = 3x - 2

Step-by-step explanation:

(1,1) and (2,4)

Slope = (4 - 1)/(2-1) = 3, y- intercept b = -2

Equation

y = 3x - 2

Answer:

Y = 3x - 2 will be the answer.

Step-by-step explanation:

A line has been graphed in the figure attached.

It passes through two points ( 1,1) and (2,4)

Y-intercept of the given line is (-2)

Since equation of a line in the intercept form is

y = mx + c

where m = slope and c = y-intercept

and slope m =  [tex]\frac{y-y'}{x-x'}[/tex]

Therefore, slope m =  [tex]\frac{4-1}{2-1}[/tex]

                                =  [tex]\frac{3}{1}[/tex]

Therefore, equation of the given line will be y = 3x - 2

Answer:

C. an irregular concave heptagon

Explanation:

Before we begin, we should define the terms used in the choices given:

1- Heptagon: It is the polygon that has 7 sides

2- Regular heptagon: It is a 7-sided polygon in which all sides are equal and all angles are equal

3- Irregular heptagon: It is a 7-sided polygon in which neither the sides nor the angles are equal

4- Concave heptagon: It is a 7-sided polygon in which one or more of its angles are more than 180°

5- Convex heptagon: It is a 7-sided polygon in which all its angles are less than 180°

6- Complex heptagon: It is a 7-sided polygon whose dimensions are in the complex plane

Now, let's check the given diagram:

It is a 7-sided polygon, therefore, it is a heptagon

It's sides as well as its angles are not equal, therefore, it is an irregular heptagon

It has interior angles measuring more than 180°, therefore, it is a concave heptagon

Its dimensions are not in the complex plane, therefore, it is not a complex polygon

Based on the above, the best choice is:

C. an irregular concave heptagon

Hope this helps :)

A heptagon is a seven-sided polygon. Regular heptagons have all equal sides and angles, irregular convex heptagons have unequal sides but all angles less than 180 degrees, irregular concave heptagons have at least one interior angle more than 180 degrees while complex heptagons have intersecting sides.

In mathematics, a heptagon is a seven-sided polygon. A- A regular heptagon is a heptagon in which all seven sides and all seven angles are congruent, meaning they are of equal length or degree. B- An irregular convex heptagon has seven sides, but they are not all equal, however, all its interior angles are less than 180 degrees. C- An irregular concave heptagon is also an irregular heptagon, but at least one of its interior angles is more than 180 degrees. D- A complex heptagon is a heptagon with sides that intersect each other, but this is not a standard classification in geometry.

Step-by-step explanation:

Given sinP = [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]

Then the right triangle has a hypotenuse of 13 and a leg 5

Use Pythagoras' identity to find the other leg x ( adjacent)

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12 , hence

tanP = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{12}[/tex]

The value of the tanP when sin is equal to 5/13  is 5/12.

We have given that,

[tex]sinP = \frac{5}{13}[/tex]

[tex]sin(\theta)=\frac{Opposite}{hypogenous}[/tex]

Then the right triangle has a hypotenuse of 13 and a leg of 5

Use Pythagoras' identity to find the other leg x ( adjacent)

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

taking square root on both sides

[tex]x=\sqrt{144} \\x=12[/tex]

Therefore we get the value of the tanP.

[tex]tanP = \frac{opposite }{adjucent} = \frac{5}{12}[/tex]

Therefore the value of the tanP is 5/12.

Answer:

Step-by-step explanation:

when the two angles are added they are equal to 180 degree. (corresponding angles property)

x+8+3X+2=180

4X+10=180

4X=170

X=44.25 DEGREES

Question 1:

For this case we have that by definition, if a and b are two parallel lines, then the corresponding angles are congruent, that is, we can write 3x + 2 and x + 8 as supplementary angles:

[tex](3x + 2) + (x + 8) = 180\\3x + 2 + x + 8 = 180\\4x + 10 = 180\\4x = 180-10\\4x = 170\\x = \frac {170} {4}\\x = 42.5[/tex]

We look for the value of the angles:

[tex]3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]

ANswer:

[tex]x = 42.5\\3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]

Question 2:

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

Now, in the equation [tex]y = 2x + 3[/tex]

[tex]m = 2\\b = 3[/tex]

By definition, if two lines are parallel, their slopes are equal. Also, if two lines are perpendicular, then the product of their slopes is -1.

So:

The slope of a line parallel to the given line is:

[tex]m = 3[/tex]

The slope of a line perpendicular to the given line is:

[tex]3 * m = -1\\m = - \frac {1} {3}[/tex]

ANswer:

Final answer:

Denise will need to pay $464.29 each month for 14 months to repay a $6500 loan and avoid any interest charge.

Explanation:

To calculate how much Denise will need to pay each month to avoid an interest charge on her $6500 loan, we simply divide the total loan amount by the number of months she has to repay the loan.

So, the monthly payment Denise needs to make is $6500 divided by 14 months:

$6500 ÷ 14 months = $464.29 per month (rounded to two decimal places).

To repay the full amount in 14 months and avoid any interest, Denise will need to pay $464.29 each month.

Step-by-step explanation:

Mean absolute deviation is the average distance between the data points from the set to the mean point of the data set. It shows the variability in data or how much the data points are spread.

method to calculate Mean absolute deviation:

a. calculate mean

b. calculate absolute deviation of each data point

c. add all the deviations

d. divide absolute deviation by number of points

mean absolute deviation = ∑l[tex]x_{i}[/tex]-xl / n

The given problem has four sub-parts

Solution 1:

Mean= (78+99+90+80+55+56+102+88+60+42)/10

            =  750/10

            =  75

Mean absolute deviation= ( I 78-75 I + I 99-75 I+I 90-75 I + I 80-75 I +

                                             I 55-75 I + I 56-75 I + I 102-75 I + I 88- 75 I +

                                             I 60-75 I + I 42-75 I) /10

         =  (174)/10

        =  17.4

Solution 2:

Mean = (10+13+7+12+9+8+12+10+11+13)/10

              =  (105)/10

              = 10.5

Mean absolute deviation = ( I 10-10.5 I + I 13-10.5 I + I 7-10.5 I + I 12-10.5 I +

                                              I 9-10.5 I + I 8-10.5 I + I 12-10.5 I + I 10-10.5 I +

       =   17/10

       = 1.7

Solution 3:

Mean= (1+7+10+5+3+3+6+12+9+4)/10

            =  60/10

            =  6

Mean absolute deviation  = ( I 1-6 I + I 7-6 I + I 10-6 I + I 5-6 I + I 3-6 I +

                                               I 3-6 I + I 6-6 I + I 12- 6 I + I 9-6 I + I 4-6 I) /10

         = (28)/10

        =  2.8

Solution 4:

Mean= (30+46+25+45+18+25+15+32+40+24)/10

            =  300/10

            =  30

Mean absolute deviation  = ( I 30-30 I + I 46-30 I + I 25-30 I + I 45-30 I +

                                               I 18-30 I + I 25-30 I + I 15-30 I + I 32-30 I +

                                               I 40-30 I + I 24-30 I) /10

Answer: Option A; 19

Step-by-step explanation:

The data is:

We have 40 students.

16 play football

9 play basketball

4 play bot sports.

We want to find the number of students that do not play either sport, for this we should add the number of students that play football and the number of students that play basketball, subtracting the number of students that play both sports (because we sill be counting those two times, this is because those 4 students are included in the 16 for football and also in the 9 for basketball.)

N = 16 + 9 - 4 = 12 + 9 = 21

the number of students that do not play basket or football is equal to:

40 - N = 40 - 21 = 19

Answer:

x = 137

Step-by-step explanation:

∠43° and ∠x° are same side exterior angles as they are on the same side as the transversal but outside the parallel lines. The 2 angles are supplementary, hence

x + 43 = 180 ( subtract 43 from both sides )

x = 137

Based on the information given, the value of x will be 137°.

It should be noted that angles x and 43° are on the same side of the transversal but they're are outside the parallel lines. In this case, the angles are supplementary which means that when they are added together, their total angles equal 180°.

Therefore, the value of angle x will be:

= 180° - 43°

= 137°

Therefore, x is 137°.

Step-by-step explanation:

if you read the problem carefully you will notice that there are actually 2 ways of solving this problem. the first is by looking at the arc as if it is across from angle A, while the second is so the arc is across from side BC and bisected by point A (because the triangle is isosceles).

first way:

102/2=51°=m∠A

180-51=129°=m∠B+m∠C

129/2=m∠B=m∠C=64.5°

answers: 64.5°, 64.5°, 51°

second way:

51/2=m∠B=m∠C=25.5°

180-51=129°=m∠A

answers: 25.5°, 25.5°, 129°

Hope this helps!:)

The central angle BOC is twice the measure of arc BC, so it is 204°. Since the circle is 360°, the sum of the other two angles is 156°. Being an isosceles triangle, angles ABC and ACB are equal, thus each is 78°.

To find the measure of the angles of an isosceles triangle ABC inscribed in a circle, with the measure of arc BC being 102°, we utilize the properties of a circle and the fact that an isosceles triangle has two equal angles. In a circle, the angle subtended by an arc at the center is twice the angle subtended on the circumference. Thus, if the measure of arc BC is 102°, the central angle BOC would be 204° (since it's twice the angle at the circumference).

This central angle separates the circle into two segments, one of which is the base of the isosceles triangle. The other two angles of the triangle, angles A and ABC or ACB (since it's an isosceles triangle, these angles are equal), will each occupy the remaining portion of the circle that amounts to 360° - 204° = 156°. Since the angles at B and C are equal in an isosceles triangle, we divide the remaining 156° by 2 to find each angle. Therefore, angle A = 204°, and each of the other two angles is 78°.
