Hoi Chong Transport, Limited, operates a fleet of delivery trucks in Singapore. The company has determined that if a truck is driven 177,000 kilometers during a year, the average operating cost is 12.3 cents per kilometer. If a truck is driven only 118,000 kilometers during a year, the average operating cost increases to 15.5 cents per kilometer.
Required:
1. Using the high-low method, estimate the variable operating cost per kilometer and the annual fixed operating cost associated with the fleet of trucks.
2. Express the variable and fixed costs in the form Y = a + bX.
3. If a truck were driven 147,000 kilometers during a year, what total operating cost would you expect to be incurred?
Answer:
Explanation:
To use the high-low method, we need to find the difference in operating costs between the high and low levels of activity, and then divide that difference by the difference in activity levels.
Variable cost per km = (15.5 cents - 12.3 cents) / (118,000 km - 177,000 km)
Variable cost per km = -0.0005 cents
To find the fixed operating cost, we can use either of the activity levels and substitute in the variable cost per km we just calculated:
12.3 cents = Fixed cost + (177,000 km x -0.0005 cents)
Fixed cost = 210.6 dollars
So the estimated variable cost per kilometer is -0.0005 cents, and the estimated fixed cost is 210.6 dollars.
Expressing the costs in the form Y = a + bX:
Y = Total operating cost
a = Fixed cost = 210.6 dollars
b = Variable cost per km = -0.0005 cents
X = Number of kilometers driven
Y = 210.6 dollars - 0.0005 cents/km x 147,000 km
Y = 135.1 dollars
So if a truck were driven 147,000 kilometers during a year, the total operating cost would be approximately 135.1 dollars.
4. Many people start smoking and/or drinking alcohol as teenagers. Choose either drinking or smoking as an example and explain why this age is a particularly vulnerable time to initiate these behaviors. Develop a behavioral intervention for a teenager who has a problem with excessive smoking or drinking.
With regards to the behavioral intervention prompt, I will choose smoking as an example. The teenage years are a particularly vulnerable time to initiate smoking because the adolescent brain is still developing, and nicotine can cause permanent changes to the brain that increase the risk of addiction.
What is the explanation for the above response?Note that social and environmental factors, such as peer pressure, stress, and exposure to tobacco advertising, can also influence a teenager's decision to start smoking.
To develop a behavioral intervention for a teenager who has a problem with excessive smoking, a comprehensive approach is needed. This may involve counseling, social support, and nicotine replacement therapy. Counseling can help the teenager to identify triggers for smoking, develop coping strategies, and set goals for quitting. Social support from family, friends, or a support group can provide encouragement and accountability.
Nicotine replacement therapy, such as nicotine gum or patches, can help to manage withdrawal symptoms and reduce cravings. Additionally, education on the health consequences of smoking and strategies to avoid triggers can be helpful in preventing relapse.

h. Using a bullet-pointed list, describe the geologic history of the map area. Hint: start with
the oldest event and describe events as they occurred up to the present day
this Geology/earth science
Answer:
- The oldest event in the geologic history of the map area is the deposition of the basement rocks, which are composed of metamorphic and igneous rocks that formed between 1.7 and 1.0 billion years ago.
- These basement rocks were then intruded by a series of granitic plutons between 1.0 and 0.9 billion years ago.
- The next major event in the area's geologic history was the deposition of a thick sequence of sedimentary rocks that formed during the Paleozoic Era, between 542 and 251 million years ago.
- These sedimentary rocks include sandstones, shales, and limestones, and they were deposited in a shallow marine environment.
- During the Mesozoic Era, between 251 and 66 million years ago, the area was uplifted and eroded, and the sedimentary rocks were tilted and faulted.
- In the Cenozoic Era, between 66 million years ago and the present day, the area was uplifted further and subjected to a series of volcanic eruptions that deposited lava flows and pyroclastic deposits.
- The most recent event in the area's geologic history is the ongoing erosion and weathering of the exposed rocks, which has resulted in the formation of the current landscape.

It should be noted that f(x) is increasing on the interval (-∞, 1).
How to explain the function2e^-x - 2xe^-x > 0
2e^-x > 2xe^-x
Dividing both sides by 2e^-x (which is always positive), we get:
1 > x
Therefore, f(x) is increasing on the interval (-∞, 1).
Also f'(x) = 2e^-x - 2xe^-x
At x = 1, we have:
f'(1) = 2e^-1 - 2e^-1 = 0
Since f'(x) changes sign from negative to positive as we move from x = 1 to x < 1, we conclude that f(x) has a relative minimum at x = 1.

What is the area of the region in the third quadrant bounded by the y-axis and the following functions: f ( x ) = x 2 − 8 , g ( x ) = − x 2 , and h ( x ) = 2 x − 5 ?
The area of the region in the third quadrant bounded by the y-axis and the following functions the area of the region is E. 197/15.
To find the area of the region in the third quadrant bounded by the y-axis and the given functions, we need to find the points of intersection of the functions and integrate the function that is on top minus the function on the bottom.
First, we find the points of intersection of the functions:
f(x) = g(x) -> x^2 - 8 = -x^2 -> 2x^2 = 8 -> x = ±2
g(x) = h(x) -> -x^2 = 2x - 5 -> x^2 + 2x - 5 = 0 -> x = (-2 ± sqrt(24))/2 = -1 ± 2sqrt(6)/2 = -1 ± sqrt(6)
Now, we need to determine which function is on top for each interval:
On the interval [-2, -1 - sqrt(6)], g(x) is on top.
On the interval [-1 - sqrt(6), -2], h(x) is on top.
On the interval [-2, 2], f(x) is on top.
Therefore, the area of the region is:
integral from -2 to -1 - sqrt(6) of g(x) dx
+ integral from -1 - sqrt(6) to -2 of h(x) dx
+ integral from -2 to 2 of f(x) dx
= integral from -2 to -1 - sqrt(6) of (-x^2) dx
+ integral from -1 - sqrt(6) to -2 of (2x - 5) dx
+ integral from -2 to 2 of (x^2 - 8) dx
= [(1/3)*(-1-sqrt(6))^3 - (1/3)*(-2)^3]
+ [(1/2)*((-1-sqrt(6))^2 - (-2-sqrt(6))^2) - (2*(-1-sqrt(6)) - 5)*sqrt(6) + (2*(-2) - 5)*sqrt(6)]
+ [(1/3)*(2^3) - (1/3)*(-2)^3 - (1/3)*(2^3) + (1/3)*(-(-2)^3)]
= (1/3)*(9+7sqrt(6)) + (1/2)*(7+4sqrt(6)) + (8/3)
= 197/15
Therefore, the area of the region is E. 197/15.
