Devon should use motor 2 with body 1 to build the car with the greatest acceleration.
To determine which combination of motor and body would result in the greatest acceleration for the toy car, we need to calculate the force-to-mass ratio for each combination. The greater the force-to-mass ratio, the greater the acceleration.
For motor 1 and body 1:
Force-to-mass ratio = Force / Mass
= 10 N / 0.2 kg
= 50 N/kg.
For motor 1 and body 2:
Force-to-mass ratio = Force / Mass
= 10 N / 0.6 kg
= 16.67 N/kg.
For motor 2 and body 1:
Force-to-mass ratio = Force / Mass
= 15 N / 0.2 kg
= 75 N/kg.
For motor 2 and body 2:
Force-to-mass ratio = Force / Mass
= 15 N / 0.6 kg
= 25 N/kg.
Comparing the force-to-mass ratios, we can see that the combination with the greatest acceleration would be motor 2 with body 1, as it has a force-to-mass ratio of 75 N/kg. Therefore, Devon should use motor 2 with body 1 to build the car with the greatest acceleration.

Is the circle opean or closed in the equation p<-18
The circle in the equation p<-18 is open. In mathematical notation, the symbol "<" represents "less than." Therefore, the inequality p<-18 means that the value of p is less than -18.
When graphing this inequality on a number line, we use an open circle to represent the endpoint, which in this case is -18. An open circle indicates that the value of p cannot equal -18.
To understand this concept, consider the inequality p<5. In this case, the graph would show an open circle at 5, indicating that p can be any value less than 5 but not equal to 5. Similarly, in p<-18, the open circle at -18 signifies that p can take on any value less than -18 but cannot be equal to -18. This distinction is crucial when interpreting inequalities and their graphs.

1) How can we get Equation BBB from Equation AAA?
Equation BBB is obtained from Equation AAA by simplifying and combining like terms.
How to get Equation BBB from Equation AAATo get Equation BBB from Equation AAA, we can simplify the expression by combining like terms and applying the rules of algebra.
In Equation AAA, we have:
5x - 2 + x / (5x + x) = x - 4
First, we can simplify the denominator in the fraction by combining the terms 5x and x:
5x + x = 6x
So, the equation becomes:
5x - 2 + x / 6x = x - 4
Next, we can multiply both sides of the equation by 6x to eliminate the fraction:
(5x - 2 + x) * 6x / 6x = (x - 4) * 6x
This simplifies to:
(6x)(5x - 2 + x) = 6x(x - 4)
Expanding both sides:
[tex]30x^2 - 12x + 6x^2 = 6x^2 - 24x[/tex]
Combining like terms:
[tex]36x^2 - 12x = 6x^2 - 24x[/tex]
Subtracting 6x^2 and adding 24x from both sides:
[tex]30x^2 + 12x = 0[/tex]
Dividing both sides by 6x:
5x^2 + 2x = 0
Now we have Equation BBB:

Determine whether the function f(x) = 2x2 - x + 2 is continuous at x = 2 A. Yes, because the function is defined at x = 2 B. None of these are correct C. Yes, because the function is defined at x = 2 and approaches y = 8 on the left and right sides of x = 2 D. Yes, because the function approaches the same y-value 8 on the left and right sides of x = 2
The function f(x) = 2x2 - x + 2 is continuous at x = 2, the correct option is C. Yes, because the function is defined at x = 2 and approaches y = 8 on the left and right sides of x = 2.
A continuous function is a type of function in mathematics that has no abrupt changes or breaks in its graph. It is a function where the values change smoothly as the input values vary. In other words, a function is continuous if its graph can be drawn without lifting the pen from the paper.
Given the function f(x) = 2x² - x + 2.
Determine whether the function is continuous at x = 2.
Explanation: For a function to be continuous at x = a, it must satisfy the following conditions:
1. The function must be defined at x = a.
2. The limit of the function at x = a must exist.
3. The limit of the function at x = a must be equal to the value of the function at x = a.
Let us verify these conditions for the given function
f(x) = 2x² - x + 2 at x = 2.
1. The function is defined at x = 2.
2. We need to calculate the left-hand limit and the right-hand limit of the function as x approaches 2.
Let us first calculate the left-hand limit:
lim f(x) as x → 2- = lim (2x² - x + 2)
as x → 2- = 2(2)² - 2 + 2
= 6
Now, let us calculate the right-hand limit:
lim f(x) as x → 2+ = lim (2x² - x + 2)
as x → 2+ = 2(2)² - 2 + 2
= 6
Since both the left-hand limit and the right-hand limit of the function exist and are equal to 6, the limit of the function at x = 2 exists and is equal to 6.
3. We need to verify whether the limit of the function at x = 2 is equal to the value of the function at x = 2.
Let us calculate the value of the function at x = 2:
f(2) = 2(2)² - 2 + 2
= 8
Since the limit of the function at x = 2 is equal to the value of the function at x = 2,
we can say that the given function f(x) = 2x² - x + 2 is continuous at x = 2.
Thus, the correct option is C.

Let the weight of the entire box be x pounds. Now, Roger served 5/8 pound of crackers, which was 2/3 of the entire box.
Therefore, the weight of the crackers left in the box = (1 - 2/3) x = 1/3 xSince the crackers served by Roger was 5/8 pound, the weight of the crackers left in the box = x/3, then we can set up the following equation to find the value of x:5/8x + 1/3x = x
Multiplying the equation by 24 (the least common multiple of 8 and 3) on both sides gives us:
15x + 8x = 24x
Therefore, 23/24 x = 5/8 pound of crackers served by Roger.So, x = (5/8) x (24/23) pounds = 15/23 pounds
To solve the given question, let us suppose that the weight of the entire box of crackers is x pounds. Now, the given information is that Roger served 5/8 pound of crackers which was 2/3 of the entire box.

When the angle of elevation of the sun is a telephone pole that is tilted at an angle of directly away from the sun casts a shadow 20 feet long. Determine the length of the pole to the nearest tenth of a foot.
Given that a telephone pole casts a shadow of 20 feet when the angle of elevation of the sun is directly away from the pole, the task is to determine the length of the pole to the nearest tenth of a foot.
We can use the concept of similar triangles to solve this problem. The telephone pole, the shadow, and the sun form two right triangles that are similar to each other. Let's assume the height of the pole is h feet. The length of the shadow is given as 20 feet. Since the angle of elevation of the sun is directly away from the pole, the angle between the shadow and the height of the pole is 90 degrees.
By considering the two similar triangles, we can set up a proportion: the length of the shadow / the height of the pole = the length of the adjacent side / the length of the opposite side. This can be written as 20 / h = tan(angle of elevation).To solve for h, we can rearrange the equation: h = 20 / tan(angle of elevation).
Since the angle of elevation is not given in the problem, we cannot calculate the exact length of the pole. However, if the angle of elevation is provided, we can substitute it into the equation to find the length of the pole to the nearest tenth of a foot.

consider the function f (x)=3x-11 Calculate its average rate of change between x=0.and x=6. Show all the work that leads to your final answer.
The average rate of change of the function f(x) = 3x - 11 between x = 0 and x = 6 is calculated by finding the difference in the function values at the two points and dividing it by the difference in the x-values. In this case, the average rate of change is equal to 3.
To find the average rate of change between x = 0 and x = 6, we need to evaluate the function at these two points and calculate the difference in the function values.
Let's substitute the values of x into the function:
f(0) = 3(0) - 11 = -11
f(6) = 3(6) - 11 = 13
Now we can find the difference in the function values:
Difference = f(6) - f(0) = 13 - (-11) = 24
Next, we calculate the difference in the x-values:
Δx = 6 - 0 = 6
Finally, we divide the difference in the function values by the difference in the x-values to obtain the average rate of change:
Average rate of change = Difference / Δx = 24 / 6 = 4
Therefore, the average rate of change of the function f(x) = 3x - 11 between x = 0 and x = 6 is equal to 4.

Davidson is on a cross country motorcycle trip and has just arrived at the foothills of the Rockies. He plans to take 1 hour longer on the 245 km trip up the east side than on the 225 km trip down the west side. To do this he will average 20 km/h faster on the downhill side. How long will the trip through the Rockies take?
Davidson has just arrived at the foothills of the Rockies and is on a cross-country motorcycle trip. He intends to take an hour longer on the east side of the 245 km trip than on the west side of the 225 km trip. On the downhill side, he intends to average 20 km/h more to achieve this. The trip through the Rockies will take approximately 17.375 hours.
Let the speed of the motorcycle on the west side of the trip be x km/h.
So, the time required to complete the 225 km trip will be:
Time for the west side of the trip = 225/x
Let the speed of the motorcycle on the east side of the trip be x + 20 km/h.
So, the time required to complete the 245 km trip will be:
Time for the east side of the trip = 245 / (x + 20)
We know that the time Davidson takes on the east side of the trip will be an hour longer than on the west side. Therefore, we can form the following equation:
245/(x + 20) = 225/x + 1
Multiplying both sides by x(x + 20),
we get:245x = 225(x + 20) + x(x + 20)
Simplifying the equation:20x = 400x = 20 km/h
Time taken on the west side of the trip is 225/20 = 11.25 hours
Time taken on the east side of the trip is 245/40 = 6.125 hours
So the total time for the trip through the Rockies is 11.25 + 6.125 = 17.375 hours, or about 17 hours and 22.5 minutes (rounded to the nearest minute).
Therefore, the trip through the Rockies will take approximately 17.375 hours.

To find the total area of all three gardens, we need to calculate the area of one garden and then multiply it by three.
Each garden is in the shape of a square with a 3-foot by 3-foot section removed from each of the four corners. This means the side length of each garden's square portion is (16 ft - 3 ft) = 13 ft. Therefore, the area of one garden is (13 ft)^2 = 169 sq ft.
To find the total area of all three gardens, we multiply the area of one garden (169 sq ft) by three:
Total area = 169 sq ft/garden × 3 gardens = 507 sq ft.
Therefore, the total area of all three gardens is 507 square feet.

To calculate the earnings per share, we need to divide the company's profit by the number of outstanding shares. The given information includes the company's profit of $117,667,008 and the share price of $56.97.
To determine the earnings per share, we need to know the number of outstanding shares. Since the number of outstanding shares is not provided in the given information, it is not possible to calculate the earnings per share with the given data alone.
The earnings per share (EPS) is calculated by dividing the company's profit by the number of outstanding shares. It represents the portion of the company's profit that is allocated to each outstanding share. By dividing the profit by the number of shares, we can determine how much profit is attributable to each individual share.
However, without the number of outstanding shares, we cannot calculate the exact earnings per share. The market capitalization and current share price do not provide enough information to determine the number of shares outstanding. Additional information, such as the number of shares issued by the company, is needed to calculate the earnings per share accurately.
In summary, the earnings per share cannot be determined with the given information alone. The calculation requires the number of outstanding shares, which is not provided. The earnings per share is a measure of the company's profitability allocated to each share, obtained by dividing the company's profit by the number of outstanding shares.
