A linear graph is a straight line graph. Thus, the graph does not represent a linear function.
A quadratic graph is either U-shaped or n-shaped. It is mostly in a parabolic form. Thus, the graph does not represent a quadratic function.
An exponential graph has asymptotic to the x-axis as x approaches negative infinity and the graph increases without bound as x approaches positive infinity. Also, the domain is all real numbers. Hence, the graph represents an exponential function.

The two top concert tours in 2016 were concert A and concert B. Based on average ticket prices, it cost a total of $1707 to purchase six tickets for concert A and six tickets for concert B. Three tickets for concert B cost a total of $687. How much did an average ticket cost for each tour?
Answers
The average ticket cost for each concert is given as follows:
Concert A: $188.83.Concert B: $95.67.How to obtain the ticket costs?The ticket costs are obtained by a system of equations, for which the variables are given as follows:
Variable a: cost for Concert A.Variable b: cost for Concert B.It cost a total of $1707 to purchase six tickets for concert A and six tickets for concert B, hence:
6a + 6b = 1707
a + b = 284.5.
Three tickets for concert B cost a total of $687, hence the cost for concert B is of:
3b = 687
b = 287/3
b = $95.67.
Replacing into the first equation, the cost for concert A is given as follows;
a = 284.5 - 95.67
a = $188.83.

What is the measure of <A in the triangle below?
Answers
Answer:
62
Step-by-step explanation:
180-116 makes us find out that angle C is 64, thus to find out the inner angles you gotta do 64+ (2x+4)+(3x-13)=180
You follow this operation, find out x and perform 3(25)-13, which ends up giving you 62
Answer:
62°
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is not sharing a common side
2x + 4 + 3x - 13 = 116° add like terms
5x - 9 = 116°
5x = 125° divide both sides by 5
x = 25 and angle A is 3x - 13 so 3×25 - 13 = 62°
Find an equation for the perpendicular bisector of the line segment whose endpoints are (5,5)(5,5) and (-9,9)(−9,9).
Answers
The equation of the perpendicular line is
y = (7/2)x + 14
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Line segment with two endpoints (5, 5) and (-9, 9)
The slope of the line segment.
m(1) = (9 - 5) / (-9 - 5) = 4 / -14 = -2/7
m(1) = -2/7
Now,
The equation of the perpendicular line.
y = m(2)x + c.
Since the line is perpendicular to the line segment.
m(1) x m(2) = -1
-2/7 x m(2) = -1
m(2) = 7/2
Now,
The perpendicular bisector passes through the midpoint of the line segment.
The midpoint of the line segment.
x = (5 - 9) / 2 = -4/2 = -2
y = (5 + 9) / 2 = 14/2 = 7
Now,
The equation of the perpendicular line.
y = m(2)x + c.
7 = 7/2 x -2 + c
7 = -7 + c
c = 7 + 7 = 14
Thus,
The equation of the perpendicular line is
y = (7/2)x + 14

A is thrice as good as workman as B and therefore is able to finish a job in 60 days less than B. Working together, they can do it in
20.4 days
22.5 days
25.6 days
30.1 days
Answers
Let's assume that B can do the job alone in x days.
Then, according to the question, A can do the same job alone in (1/3)x days.
Also, we know that A takes 60 days less than B to finish the job, so:
(1/3)x = x - 60
Solving for x, we get:
x = 90
Therefore, B can do the job alone in 90 days and A can do the same job alone in (1/3) * 90 = 30 days.
To find out how long they take to finish the job together, we use the formula:
(AB)/ (A+B)
where AB is the product of their individual times and A+B is their combined time.
Plugging in the values, we get:
(30 * 90)/(30+90) = 22.5
Therefore, working together, they can finish the job in 22.5 days.
Answer: Option B - 22.5 days

Answers
The required number of tickets sold for the semi-final matches is 12270.
there are 49080 tickets have been sold for the tournament. \(\frac{3}{5}\) of the tickets are for the qualifying matches and 15% of the tickets are for the final match.
We have to find the number of tickets that are sold for the semi-final matches.
Let s denotes the number of tickets that are sold for semi final matches.
According to the given information, we have
Number of tickets sold for the qualifying matches is
\(n_{q} =\frac{3}{5} *49080=29448\)
and the number of tickets sold for the final match is
\(n_{f}=15\)% * 49080=\(\frac{15}{100} *49080=7362\)
So therefore we must have,
\(n_{f} +n_{q} +s\)= 49080
29448+7362+s= 49080
36810 + s =49080
s = 49080-36810
s=12270
therefore the required number of tickets sold for the semifinal matches is 12270.

10. The following measurements from yaw marks left at the scene of an accident were taken by law

ft. The drag factor for the road surface is 1.02.
a. Determine the radius of the yaw mark to the nearest tenth of a foot.
1
Determine the minimum snood that it
Answers
The radius of the yaw mark to the nearest tenth of a foot is 11.2 ft
The minimum speed 11.1634 miles per hour.
What is Yaw mark?Yaw marks are always curved. They are, initiated by a steering input. They're what's left from a tire that is still rolling but is simultaneously sliding laterally.
The formula for determining radius from a chord and middle ordinate is
\(r^{2}= \frac{c^{2}}{8m}+\frac{m}{2}\)
To find the radius of the yaw mark, we have to use the formula
\(r^{2}= \frac{c^{2}}{8m}+\frac{m}{2}\)
where c is the length of the chord and m is the middle ordinate
As the tires leave a yaw mark with a 31 foot chord and a middle ordinate of 3 feet.
So,
\(r^{2}= \frac{31^{2}}{8*3}+\frac{3}{2}\)
\(r^{2}= 40.041 +1.5\\r^{2}=41.541\)
Now to find the minimum speed, we are going to use the formula: \(s=\sqrt{15fr}\)
where 'f' is drag factor and 'r' is the radius
drag factor is 0.2, f=0.2
and r= 41.541 ft
So, \(s=\sqrt{15* 0.2*41.541}\\s=\sqrt{124.623}\\s= 11.1634 mph\)
The minimum speed before the brakes are applied was 11.1634 miles per hour.

AB and AD are tangent to circle C. Find the length of AB, if AB = 8x and AD = x + 9. Round your answer to 2 decimal places.
Answers
When a line is tangent to a circle, it forms a right angle with the radius drawn to the point of tangency. This means that triangle ABD is a right triangle with AB as the hypotenuse.
We can use the Pythagorean theorem to find the length of AB:
AB^2 = AD^2 + BD^2
Since AD = x + 9 and BD = 8x - (x + 9) = 8x - x - 9 = 7x - 9, we can substitute these values into the equation:
(8x)^2 = (x + 9)^2 + (7x - 9)^2
64x^2 = x^2 + 18x + 81 + 49x^2 - 126x + 81
64x^2 = 50x^2 - 108x + 162
14x^2 + 108x - 162 = 0
Dividing the equation by 2, we get:
7x^2 + 54x - 81 = 0
Using the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
a = 7, b = 54, c = -81
x = (-54 ± √(54^2 - 4 * 7 * -81)) / (2 * 7)
x = (-54 ± √(2916 + 2268)) / 14
x = (-54 ± √5184) / 14
x = (-54 ± 72) / 14
Now we solve for x:
Case 1: x = (-54 + 72) / 14 = 18 / 14 = 9 / 7
Case 2: x = (-54 - 72) / 14 = -126 / 14 = -9
Since the length of a segment cannot be negative, we discard the second case and focus on the positive solution.
Therefore, x = 9/7.
Substituting this value back into AB = 8x:
AB = 8 * (9/7) = 72/7 ≈ 10.29
Rounding to 2 decimal places, the length of AB is approximately 10.29 units.
Answer:
To find the length of AB, we can use the property that two tangents to a circle from the same external point are equal. This means that AB = AD. Substituting the given values, we get:
8x = x + 9
Solving for x, we get:
x = 1.5
Therefore, AB = 8x = 8(1.5) = 12.
To check our answer, we can use the Pythagorean theorem on triangle ABD, since AB is perpendicular to BD at the point of tangency. We have:
AB^2 + BD^2 = AD^2
Substituting the values, we get:
12^2 + BD^2 = (1.5 + 9)^2
Simplifying, we get:
BD^2 = 56.25
Taking the square root of both sides, we get:
BD = 7.5
Hence, the length of AB is 12 and the length of BD is 7.5.
