You are recently promoted as the chief traffic management officer of a major city in the country. Based on recent data, you learned that one of the leading causes of road accidents is over speeding.
In your desire to minimize road accidents, you went out to observe how traffic management rules are implemented on the streets. Your attention was caught by a fast - moving car that seemed to be breaking the speed limit of 100 kilometers per hour(km/hr.), and so you followed it along the highway. After a short time, the driver of the car noticed you and started to slow down. Eventually, he stopped on the side of the road.
Supposed the speed of the car had been noted during this time and is modeled by the quadratic equation y = 3x² + 17x - 20, where y represents the speed of the car in km/hr. and x represents the number of minutes after you started following the car. How long did it take for the car to be under surveillance before it could finally stop on the side of the road? Did the driver of the car really break the speed limit of 100 km/hr.? Explain. The result of your observation will be presented to the students in your section and will be graded by your teacher.

Answer: Percentage decrease = 20% × 7,720
New value = 7,720 - Percentage decreaseNew value =
7,720 - Percentage decrease =

Answer:
The second table with all values of x = -5 does not represent a function. what the function and input value of x will return one and only one value for y. and this table when you input a value for x of -5 you get three different values therefore this table does not represent a function
Answer:
Step-by-step explanation:
The table
x y
-5 1
-5 -2
-5 -5
does not represent a function, because for the same input (-5) there are 3 different outputs.
Compare this to the table
x y

Answer:
x = 11
Step-by-step explanation:
∠ EAB = ∠ AED = 4x ( alternate angles )
∠ AEB and ∠ GEB are adjacent angles on a straight line and sum to 180° , so
∠ AEB + 125° = 180° ( subtract 125° from both sides )
∠ AEB = 55°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ EBC is an exterior angle of the triangle , then
∠ EBC = ∠ AEB + ∠EAB , that is
9x = 55 + 4x ( subtract 4x from both sides )
5x = 55 ( divide both sides by 5 )
x = 11
PLEASE HELP ASAP!!!!!
Answer:
x = 7
Step-by-step explanation:
The sum of exterior angles in a polygon is 360°.
( 11x - 5 )° + ( 4x + 29 )° + ( 6x + 13 )° + ( 9x - 15 )° + 67° + 61° = 360°
30x + 22 + 128 = 360
30x = 210

At the dog park, there were dogs running around. Just for fun, Tessie counted all legs, ears, and tails getting a total sum of 168. How many dogs did Tessie see in the park?
Answer:
24 dogsStep-by-step explanation:
Each dog has 4 legs, 2 ears and 1 tail, total of 7.
Number of dogs:
168 / 7 = 24Which equation demonstrates the additive identity property?
0 (7+4i)+(7-4i) = 14
O (7+4i)+ 1 = 7+4i
(7+4)(1) = 7+4)
O (7+4i)+(-7-4i)= 0
Answer:
A
Step-by-step explanation:
The Explication 0 (7+4i)+(7-4i) = 14
The correct equation which demonstrates the additive identity property is,
⇒ (7 + 4i) + 0 = 7 + 4i
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Now, If we add a real number to zero or add zero to a real number, then we get the same real number back.
Hence, The number zero is known as the identity element, or the additive identity.
For example: a + 0 = a
Hence, we can see that;
⇒ (7 + 4i) + 0 = 7 + 4i
Since, 0 is the additive identity here.
Thus, The correct equation which demonstrates the additive identity property is,
⇒ (7 + 4i) + 0 = 7 + 4i

Answer: The filled out chart is shown below.
===========================================================
Explanation:
For each row, we divide the number of locations over the population count. Treat the population values in millions. Something like 35.2 million means 35,200,000 which is the same as writing 35.2*10^6 when using scientific notation. I prefer to stick to scientific notation.
In the first row, they computed 1460/(35.2*10^6) = 0.0000415 = 4.15*10^(-5); the last entry of 4.15 for this row represents having 4.15 stores for 100,000 people. In other words, we chop off the 10^(-5) portion in 4.15*10^(-5). This is because the 10^(-5) portion represents "1 out of 100,000".
The other remaining rows are handled the same way. I'll show the steps for the second row
per capita as a decimal = 6530/(325.7*10^6) = 0.00002per capita as sci notation = 2 * 10^(-5)Starbucks per 100,000 = 2Like the previous row, each value is approximate.

Answer:
Slope of the parrelel line: -2/3x
Slope of the perpendicular line: 3/2x
Step-by-step explanation:
Lets first put this into slope intercept form:
y = mx + b
9y = -6x - 1
y = -2/3x = 1/9
So our slope is -2/3x
If we have a line parrelel to this, it means it has the exact same slope, but a different b value.
So the slope of this parellel line would also be -2/3x
Next we need to find the slope of the perpendicular line.
This is the exact opposite of our slope.
To find this, lets first understand our slope.
Our slope is the change in y over the change in x:
Δy/Δx
A perpendicular line is going to be the flipped, and negative of this.
You can think of a perpendicular line being:
-Δx/Δy
Since our slope is -2/3x
Our perpendicular line would be 3/2x
So our answer for the second question is 3/2x
Useful things to remember:
Slope of a line: Δy/ΔxSlope of a parrelel line: Δy/ΔxSlope of a perpendicular line: -Δx/ΔyHope this helps!

what value of durbin–watson statistic indicates no autocorrelation is present?
Answer:
2
Step-by-step explanation:
when the value is below 2
a situation in which no identifiable relationship exists between the values of the error term.
The value of Durbin–Watsons statistic indicates no autocorrelation is present is 2.
What is Durbin–Watsons statistic?The output of a regression model is tested for autocorrelation using the Durbin-Watson statistic. Zero autocorrelation is indicated by a value of 2.0 in the DW statistic, which has a range of zero to four. Positive autocorrelation is indicated by values below 2.0, and negative autocorrelation is shown by values over 2.0.
As, The range of the Durbin-Watson statistic is 0–4. There is no first-order autocorrelation when the number is 2 or close to 2.
The range of 1.50 to 2.50 is suitable.
A number between 0 and 4 will always be assigned to the Durbin-Watson statistic.
A value of 2.0 means that no autocorrelation in the sample was found. Positive autocorrelation is shown by values between 0 and less than 2 whereas negative autocorrelation is indicated by values between 2 and 4.

Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or maximum vertex point.
Answer:
The leading coefficient of the function shown is negative and the function shown has a maximum vertex point.
Step-by-step explanation:
The leading coefficient is the term with the highest degree in a polynomial.
For example in 4x² + 3x + 1 the leading coefficient would be 4x² as 4x² is the term with the highest degree.
The leading coefficient tells us whether the equation, when graphed, will rise or fall.
If the leading coefficient is negative then the equation will fall when graphed, in contrast if the leading coefficient is positive the equation will rise when graphed.
Looking at the graph, it appears that the equation is falling, meaning that the leading coefficient must be negative.
If the equation falls then it has a maximum point, if it rises then it has a minimum point.
Because the equation shown falls it will have a maximum point.

Write the equation of the arithmetic sequence “24, 34, 44, 54...” and then Find the 100th term.
show your work.
Answer:
1014
Step-by-step explanation:
Remember this formula to find certain terms in arithmetic sequences:
[tex]t_{n} =t_{1} +(n-1)d[/tex]
n = term number
[tex]t_{1}[/tex] = term #1
d = common difference
Sequence = 24, 34, 44, 54...
We are looking for term #100
So we do
[tex]t_{100} = 24 + (100-1)10\\t_{100} = 24 + 1000 - 10\\t_{100} = 24 + 990\\t_{100} = 1014[/tex]
