What do you mean by Displacement?In physics, displacement is defined as the change in position of an object from its initial position to its final position, measured as a straight line distance in a specific direction. It is a vector quantity, which means it has both magnitude (the distance between the starting and ending points) and direction. Displacement is different from distance, which is the actual length of the path traveled by an object regardless of its starting and ending points.
i. The person's displacement from the starting point can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the person has walked a distance of 500 yards south and 300 yards west, which forms a right triangle. Therefore, the displacement can be calculated as the square root of (500^2 + 300^2) = 583.1 yards (rounded to the nearest hundredth).
ii. To be looking back at point A from point B, the person would have to look in the direction opposite to the direction in which they walked from A to B. Since the person first walked due south and then due west, the direction in which they would have to look to be looking back at point A is north-east. This can be calculated using trigonometry, where the tangent of the angle formed between the line connecting A and B and the due south line is equal to 300/500. Therefore, the angle formed is the arctangent of (300/500) = 31.39 degrees. However, the true bearing is measured from the north and therefore, the true bearing would be 360 - 31.39 = 328.61 degrees (rounded to the nearest hundredth).
iii. If a friend is standing at point A looking at point B, they would be looking in the direction of the line connecting points A and B. To determine the true bearing, we need to find the angle formed between the due north line and the line connecting A and B. This angle can be calculated as the arctangent of (500/300) = 59.04 degrees. However, the true bearing is measured from the north and therefore, the true bearing would be 90 + 59.04 = 149.04 degrees (rounded to the nearest hundredth).

What is Proportion ?Proportion is a mathematical comparison between two numbers. According to proportion, two sets of specified numbers are said to be directly proportional to each other if they increase or decrease in the same ratio. Symbols of proportions include "::" and "=".
We approach this problem by doing a simple proportion.We can presume that the same proportion of penguins were tagged during mating season if the biologists discovered 11 tagged individuals out of 82 penguins.
The proportion should therefore be [tex]x:53=82:11[/tex] where x represents the total number of penguins. By solving this proportion, we may determine what x is worth:
[tex]11x=53*82\\\\11x=4346\\\\x=395.0909[/tex]
Since there is no such thing as half a penguin, we can round off the answer to the nearest unit.

The area of a rectangular living room is 192 square feet. The length of the room is 8 feet less than twice the width. What is the width of the living room in feet?
Answers
Answer:
The width of the living room is 10 feet.
Step-by-step explanation:
Let the width of the living room is w.
And the length of the room is 2w - 8 ft.
Given,
The area of the room is 192 feet^2, by using the formula of area of a rectangle we get,
A = l × w
192 = (2w - 8) × w
Now,
192 = 2w^2 - 8w ( By expanding)
200 = 2w^2 (By adding 8w to both sides)
100 = w^2 (Dividing both sides by 2)
If we take square root on both sides,
w = 10
So,
The width of the living room is 10 feet.

Answers
Zion Sun Chairs must sell each chair for at least $75.21 to earn a monthly profit of $65,000.
To determine the minimum sales priceTo determine the minimum sales price Zion Sun Chairs must sell each chair for to earn a monthly profit of $65,000, we can use the following formula:
Total Profit = Total Revenue - Total Cost
We know that the monthly fixed costs are $17,363.50, and the variable cost per chair is $52.17. Therefore, the total cost to produce 3,575 beach chairs each month can be calculated as follows:
Total Cost = Fixed Cost + (Variable Cost per Chair x Number of Chairs)
Total Cost = $17,363.50 + ($52.17 x 3,575)
Total Cost = $203,871.25
To earn a monthly profit of $65,000, we can set up the equation as follows:
$65,000 = Total Revenue - $203,871.25
Total Revenue =$268,871.25
To find the minimum sales price per chair, we can divide the total revenue by the number of chairs:
Minimum Sales Price per Chair = Total Revenue / Number of Chairs
Minimum Sales Price per Chair = $268,871.25 / 3,575
Minimum Sales Price per Chair ≈ $75.208
Therefore, Zion Sun Chairs must sell each chair for at least$75.21 to earn a monthly profit of $65,000, given the monthly fixed costs, variable cost per chair, and production quantity.

(1 point) Find an equation of a line perpendicular to 2 = 10 and passing through the point (3,2). The line is
Answers
An equation for a line perpendicular to the line 2 = 10 can be found by finding the slope of that line and then finding the slope of the perpendicular line. The slope of the line 2 = 10 is 0, so the slope of the perpendicular line would be undefined.
The equation of a line with slope m passing through the point (x1, y1) can be written in the form:
y - y1 = m(x - x1)
Since the slope of the line is undefined, the equation of the line would be in the form:
x - x1 = constant
To find the equation of the line that passes through the point (3, 2), we substitute the values into the equation:
x - 3 = constant
So the equation of the line that is perpendicular to the line 2 = 10 and passes through the point (3, 2) is:
x - 3 = constant
or simply:
x = 3.

The equation of the tangent plane at the point (5,4,7) on the surface z=f(x,y) is z = -3x + 7y + 8.
In 3-space, the plane tangent to a surface at a point can be imagined similarly to how we can see the line perpendicular to a curve at a point in 2-space.
The equation of the tangent plane at the point (5,4,7) on the surface z=f(x,y) can be found using the following formula:
z - [tex]z_{0}[/tex] = fx([tex]x_{0}[/tex],[tex]y_{0}[/tex])(x - [tex]x_{0}[/tex]) + fy([tex]x_{0}[/tex],[tex]y_{0}[/tex])(y - [tex]y_{0}[/tex])
where ([tex]x_{0},y_{0},z_{0}[/tex]) is the point on the surface at which we want to find the tangent plane, and fx([tex]x_{0}[/tex],[tex]y_{0}[/tex]) and fy([tex]x_{0}[/tex],[tex]y_{0}[/tex]) are the partial derivatives of f with respect to x and y, respectively, evaluated at ([tex]x_{0}[/tex],[tex]y_{0}[/tex]).
In this case, we have [tex]x_{0}[/tex] = 5, [tex]y_{0}[/tex] = 4, [tex]z_{0}[/tex] = f(5,4) = 7, fx(5,4) = -3, and fy(5,4) = 7. Substituting these values into the formula, we get:

Answer:
$20M
Step-by-step explanation:
You want the "natural breakpoint" for a lease that specifies rent is the maximum of $5 per square foot for 120,000 square feet, or 3% of sales.
Minimum rentThe minimum rent is ($5/ft²)×(120000 ft²) = $600,000.
BreakpointThe amount of sales that makes $600,000 equal to 3% of sales is ...
$600000 = 0.03s
s = $600000/0.03 = $20,000,000
The "natural breakpoint" is $20M in sales.

Additional comment
When sales exceeds $20M, 3% of sales is more than $5/ft², so the rent will be based on sales.

If it takes 6 people 8 hours to finish the job, how long would it take 4 people?
Answers
12 hours
If it takes 6 people 8 hours to finish a job, then 24 would take 2 hours, and then 4 would take 12 hours
Answer:
5.333 hours.
Step-by-step explanation:
Put this on a chart:
6 people = 8 hours
4 people = ? hours
To find ? Use crisscross multiplication and solve:
? = (4 * 8) / 6
? = 32 / 6
? = 5.333
Therefore, if it takes 6 people 8 hours to finish a job then it will take 5.333 hours for 4 people to finish a job.
(1) Find the temperature at 8:00 pm and midnight in your town. Then find the find the Difference between the two Temperatures.
(2) Clear Parenthesis and combine like terms, 12-3(x+2y-5).
Answers
1. The difference between the temperature is 14°C.
2. The value of the expression will be -3x - 6y + 27.
How to calculate the valueThe difference between the temperature will be:
= -10 + 24
= 14°C.
For the second part of your question, to clear the parenthesis in the expression "12 - 3(x + 2y - 5)", you can first simplify the expression inside the parenthesis:
x + 2y - 5
Next, multiply this expression by 3:
3(x + 2y - 5) = 3x + 6y - 15
Finally, substitute this back into the original expression:
12 - 3(x + 2y - 5) = 12 - (3x + 6y - 15) = 12 - 3x - 6y + 15 = -3x - 6y + 27
So, the final expression after clearing the parenthesis and combining like terms is -3x - 6y + 27.

• D. angle with the smallest measure
Answers
The longest side of a triangle is always opposite the,
A. angle with the greatest measure.
What is the way of classifying a triangle?If a² + b² < c² then it is an acute angle triangle.
If a² + b² = c² then it is a right-angle triangle.
If a² + b² ≥ c² then it is an obtuse angle triangle.
We know, The length of the largest side in a triangle is opposite to the largest angle.
The statement, The longest side of a triangle is always opposite the
angle with the greatest measure.
Because A longer angle will be more spread out and hence the opposite side will be longer too.

-2√x+5 +1
End behavior
Answers
Answer: The end behavior of a function is the behavior of the function as x approaches positive infinity or negative infinity.
For the function f(x) = -2√x + 5 + 1, as x approaches positive infinity, the square root of x approaches positive infinity as well. So, the function approaches negative infinity as x approaches positive infinity:
lim x → ∞ f(x) = lim x → ∞ -2√x + 5 + 1 = -∞
As x approaches negative infinity, the square root of x approaches 0, so the function approaches:
lim x → -∞ f(x) = lim x → -∞ -2√x + 5 + 1 = 7
Therefore, the end behavior of the function is that it approaches negative infinity as x approaches positive infinity, and it approaches 7 as x approaches negative infinity.
