Answer:
x = 60
Step-by-step explanation:
The sum of exterior angles in a rectangle is equal to 360
so to find the value of x we need to use all given values and write an equation:

Four lines are shown on the grid above

(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
Answers
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

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.
Answers
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.

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.

You move down 6 units. You end at (10, 4). Where did you start?
Answers
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)

The average natural gas bill for a random sample of 26 homes in the 19808 zip code during the month of March was $305.30 with a sample standard deviation of $46.50. The 80% confidence interval around this sample mean is ________.
Answers
First find degrees of freedom = sample size - 1
Or: df = 26-1 = 25
Now subtract confidence int by 1 and divide by two to make it two tailed. Remember normal distribution looks bell-shaped and we are only looking on one side for our CI.
So: (1-0.8)/2= 0.2/2=0.1 which is our alpha
Now we need to use T-distribution table that should be found in textbook or online.
For 25 df and an alpha of 0.1 I get 1.316.
Some t-dist tables will even have the confidence intervals given DF on the bottom.
Now we have to divide sample Standard deviation by sample size to find the Standard error. This basically is to look for SD of all sample means around population mean, but more on that can be found online.
So: se= 46.5/sqrt(26)
Se= 9.119 let’s call it 9.12
Now multiply standard error by value from t-dist table: 9.12*1.316 = 12.0019 let’s call it 12.
So now to find confidence interval of 80% subtract to find lower bound and add to find upper bound from given mean.
Upper: 305.3 + 12 = 317.3
Lower: 305.3 - 12 = 293.3

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.

Two bicyclists are traveling along the same road. Bicyclist A's distance, d, from a certain town after h hours Given by the equation
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.
Answers
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
