27) Electric vehicles often have been proposed as an environmentally sound alternative to the gasoline engine for transportation. In response to state initiatives, several car manufacturers now include electric vehicles among their available models. In spite of these state initiatives, the penetration of electric vehicles into the transportation sector of the United States, as well as other countries, remains modest. (a) Identify and describe two environmental benefits to using electric vehicles in place of gasoline-powered engines for transportation. (b) Estimate the potential reduction in petroleum consumption (in gallons of gasoline per year) that could be achieved in the United States by introducing electric vehicles under the following assumptions: 1. The mileage rate for the average car is 25 miles per gallon of gasoline. 2. The average car is driven 10,000 miles per year. 3. The United States has 150 million cars. 4. 10 percent of United States cars could be replaced with electric vehicles. (c) Some people have suggested that electric vehicles only shift the emission of air pollutants from dispersed sources to point sources. Explain and defend or refute this statement. (d) Propose two potential new United States government policies that would encourage the widespread use of electric vehicles. Explain.
It can be deduced that the environmental benefits of using electric vehicles are decreased levels of carbon monoxide and carbon dioxide.
What are the environmental benefits of using electric vehicles?
It improves human health by decreasing rates of headaches, drowsiness. A decrease means less global warming, decreased greenhouse effect, as well as decreased acid precipitation.
The potential reduction in petroleum consumption will be:
= (150 million cars) × (10,000 miles per year)/25 miles per gallon × 0.1
= 6 billion
Electric vehicles only shift the emission of air pollutants from dispersed sources because most electric cars are powered by an electrical generating source identified as using combustion such as fossil fuels and coal.
Some incentives that would encourage the use of electric vehicles include mandated production for electric vehicles, reduced tolls, etc.

d = 11.5h + 5
Bicyclist B's distance from the same town is shown in the graph .
Which THREE statements are TRUE?
A
B is traveling 1 mile per hour faster than A.
B
After 2 hours, A will have traveled a total of 28 miles.
С
B started from the town, while A started 5 miles from the town.
D
After 5 hours, the two bicyclists will be the same distance from the town.
E
When the two bicyclists reach the same point. A will have traveled 5 more miles than B.
The correct statement are statements B and C
Distance time graphsGiven the following equation for the distance of Bicyclist A expressed as:
d = 11.5h + 5
After 1 hour for A
d(1) = 11.5 + 5
d(1) = 16.5
For bicycle B, the distance traveled after 1 hour is 12.5 miles from the graph. Hence B is not traveling 1 mile per hour faster than A.
After 2 hours for A;
d(2) = 11.5(2) + 5
d(2) = 23 + 5 = 28 miles
Hence after 2 hours, A will have traveled a total of 28 miles.
From the graph, we can see that B started from the town (origin), and from the equation, A started from 5 miles from town (y-intercept is 5)
Hence the correct statement are statements B and C

Four lines are shown on the grid above
A)(i) write the equation of line L1
(ii) write the equation of line L2
(iii)write the value of (m) and the value of (n) for the line (y=mc+n)
(iv)write the value (p) and (q) for the line y=px+q
B) which of the letters A to K lie in the region where
(i) x >=2. y>=mx +n. and y>=px+q
(ii) y<=2. y<=mx+n. And y<=px+q
C)what is the maximum value of x+y in the region G
The lines L1 & L2 and the equations y = mx + n & y = px + q are illustrations of linear equations
The equation of line L1This is a vertical line that passes through the x = 2
So, the equation of line L1 is x = 2
The equation of line L2This is a horizontal line that passes through the y = 2
So, the equation of line L2 is y = 2
The values of m and n in y = mx + nThe line y = mx + n passes through points (6,3) and (0,0)
This means that n = 0 i.e. the y-intercept.
The value of m is calculated as follows:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
[tex]m = \frac{0- 3}{0 - 6}[/tex]
[tex]m = 0.5[/tex]
So, the values of m and n in y = mx + n are 0.5 and 0, respectively.
The values of p and q in y = px + qThe line y = px + q passes through points (6,3) and (0,12)
This means that q = 12 i.e. the y-intercept.
The value of p is calculated as follows:
[tex]p = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
This gives
[tex]p = \frac{12- 3}{0 - 6}[/tex]
[tex]p = -1.5[/tex]
So, the values of p and q in y = px + q are -1.5 and 12, respectively.
The letters in the region x >=2. y>=mx +n and y>=px+qThe above region represent the upper region between y=mx +n, y=px+q and line L1
The letter in this region is letter H
The letters in the region y <=2. y<=mx +n and y<=px+qThe above region represent the lower region between y=mx +n, y=px+q and line L2
The letters in this region are letters A and E

F. Butterfly population doubles each month
An exponential function is a function that grows exponentially.
Exponential functions have a multiplicative rate of change. This means each term can be multiplied by a specific number to get to the next.
Example of an exponential function:
1, 2, 4, 8, 16, 32, 64, 128, 256...
Knowing this, let's look at each example.
A.
The rocket grows at a rate of 45 m/s, but then goes back down. This is not an exponential function. This is most likely a quadratic function.
B.
Each term is being multiplied by 4. This is correct.
C.
This is too vague. We cannot determine what this is.
D.
This is a linear function. It has an additive rate of change; not a multiplicative one. This is wrong.
E.
Each term is 50% of the previous one. This is correct.
F.
The population is multiplied by 2 each month. This is correct.
Answer:

Doctors recommend that teenagers sleep between 9 and 912 hours each night. Melody and Wilmer construct a box plot to display sleep data collected from two samples of students. Do these data support the petition to delay the school starting time so school starts 1 hour later? Explain
Answer:
Yes because I can see people very sleep-deprived and even if 7 hours is not enough, it's better than 6. For the people who sleep 9 and a half hours, they have 1 more hour to get ready. The median is 8 which most likely means, most of the students will be able to sleep the recommended amount with the extra hour.

- Isabella makes $14.35 an hour at her company. Skyler, who works at the same company,
earns $16.35 an hour. His hourly wage increases by $0.25 each year.
How many years ago did Skyler start working at this company if his starting pay was the
same as what Isabella makes now? Show your work or explain your reasoning.
Answer:
It would be 8 years ago.
Step-by-step explanation:
-First, subtract $14.35 from $16.35, which gives you 2.
-Next, remember that $0.25 is a quarter, so how many quarters make $2?
-0.25x4 gives you a dollar, so 0.25x8 gives you 2 dollars.

You move down 6 units. You end at (10, 4). Where did you start?
Answer:
(10,10)
Step-by-step explanation:
coordinates are (x,y)
x is horizontal(left and right), y is vertical (up and down)
going down 6 means subtracting 6 from the second number
lets reverse that to go up and add 6 back
4+6=10
so the original point was (10,10)
If you move DOWN, then that means you are moving in the "y" direction (up and down).
Thus, you are moving the unit "4" not "10". Since you are moving down, you must add to know where your starting position is. You add "4" and "6" together to make "10".
Answer:
You start at (10,10)
