The weekly profit changes by $1000s/week.
What is profit?
The profit is defined as the amount gained by selling a product, and it should be more than the cost price of the product. In other words, the profit is a gain obtained from any business activities.
To find the increase in weekly revenue, we need to find the difference in revenue at the two output levels:
2500 units/week: Revenue = 100(2500) + 43 = 2543
2000 units/week: Revenue = 100(2000) + 43 = 2043
So the increase in weekly revenue is 2543 - 2043 = $500s/week.
To find the change in weekly profit, we need to subtract the change in cost from the change in revenue:
Change in cost: 2500 units/week - 2000 units/week = 500 units/week * 3 $1000s/week/unit = 1500 $1000s/week
Change in profit: $500s/week - $1500s/week = -1000
Hence, the weekly profit changes by $1000s/week.

The Salk vaccine field trials were conducted only in certain experimental areas (school districts), selected by the Public Health Service in consultation with local officials. In these areas, there were about 3 million children in grades 1, 2, or 3; and there were about 11 million children in those grades in the United States . In the experimental areas, the incidence of polio was about 25% higher than in the rest of the country. Did the Salk vaccine filed trials cause children to get polio instead of preventing it? Answer yes or no, and explain briefly.
Based on the information provided, it can be concluded that the vaccine trials most likely did not cause children to get polio as these are independent variables.
What is causality bias?This type of bias implies people believe two events are related as a cause or effect. This often happens when one event follows another, and therefore people believe one event causes the other.
In this case, people are likely to believe the vaccine caused higher polio rates just because after the vaccine, polio rates seemed to increase. However, these two variables are independent as vaccines produce immunization against polio.

What is a pentagon?A pentagon is a 2D polygon with five sides and five angles.
Pentagon is formed from three triangles, so the sum of angles in a pentagon = 3 × 180° = 540°.
We are given in the figure , following information about a pentagon:
3 angles are 90 degrees, one angle is (6x+1) degrees, and the other angle is (8x-11) degrees.
To solve for x, we need to add all of the angles together.
The sum of the angles in any polygon is always equal to (n-2)*180, where n is the number of sides in the polygon.
In this case, n=5, so the sum of the angles is (5-2)*180 = 540 degrees.

3. Ato Liku purchases a house for Br. 250, 000. He makes a 20% down payment, with a balance amortized by a 30 year mortgage at an annual interest rate of 12% compounded monthly. a) Determine the amount of the monthly mortgage payment. b) What is the total amount of interest Ato Liku will pay over the life of the mortgage? c) Determine the amount of the mortgage Ato Liku will have paid after 10 years?
Answer:
a) To determine the monthly mortgage payment, we first need to calculate the amount of the loan, which is equal to the purchase price of the house minus the down payment. In this case, the loan amount is 250,000 * 0.8 = 200,000. Next, we need to calculate the monthly interest rate, which is equal to the annual interest rate divided by 12. In this case, the monthly interest rate is 0.12/12 = 0.01. Using the formula for the monthly mortgage payment (P = L[i(1+i)^n]/[(1+i)^n-1]), where P is the monthly payment, L is the loan amount, i is the monthly interest rate, and n is the number of payments (in this case, 30 years * 12 = 360), we can calculate the monthly payment as:
P = 200,000[0.01(1+0.01)^360]/[(1+0.01)^360-1] = 1326.91
b) To calculate the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount from the total amount of payments made over the life of the mortgage. In this case, that would be 360 * 1326.91 - 200,000 = 480,596.
c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we can multiply the monthly mortgage payment by the number of payments made in 10 years (10 years * 12 = 120). In this case, that would be 120 * 1326.91 = 159,223.20.

Along x-axis, y=0.
So, slope=2x≠0.
Since it depends upon x hence the slope along the y-axis are not horizontal.
Along y-axis, x=0.
So, slope=y≠0.
Since it depends upon y the slope along the x-axis are also not horizontal.
In quadrant I -
x,y≥0
So, dy/dx≥0
Hence the slopes are all positive in quadrant I.

2. Plot the orange line segments at 90, 95, 100, 105, and 110 respectively.
The long-run aggregate supply (RAS) curve is used to represent the natural level of output for an economy. In this case, the natural level of output is $60 billion of real GDP with a price level of 100. Therefore, the purple line should be plotted at the level of output $60 billion on the graph. The short-run aggregate supply (AS) curve is used to show how the level of output reacts to the price level. Therefore, the orange line segments should be plotted at 90, 95, 100, 105, and 110 respectively. This will show how the level of output changes when the price level is different from the natural level. This will help to illustrate how the economy may react when the price level is different than expected.

If the divisor is not a whole number, move the decimal point to the 19.)______. Move also the decimal point in the dividend to the 20.)______ having the same number of decimal places as in the divisor.9.) _____20.) _____
Put the decimal point to the right to make the divisor a full number if it isn't already. The dividend's decimal point should likewise be moved the same number of spaces to the right (adding some extra zeros if necessary.)
What is meant by decimal point?To distinguish between a full number and its fractional component, a decimal point is a point or a dot. A different name for it is Decimal Mark. The decimal point is the dot that appears in the middle of a whole number and its fractional component. Decimal numbers include, for instance, 34.5. 5 is the fractional portion in this situation, and 34 is a whole number. The decimal point is ".."The word decimal derives from the Latin decimus, which means tenth, from the base word decem, or 10. As a result, the base of the decimal system, often known as the base-10 system, is 10.To learn more about decimal point, refer to:

A flute has a length of 49.0 cm. If the speed of sound in air is 343 m/s, what is the fundamental frequency of the flute, assuming it is a tube closed at one end and open at the other?
The fundamental frequency of the flute of length 49.0 cm and with its one end closed is 175 hertz.
Given,
Length of flute = 49.0 cm
Speed of sound in air = 343 m/s
The flute closed from one end and is open from the other exhibits a standing wave pattern.
We know that,
[tex]f =\frac{v}{4L}[/tex]
Now substituting values in the above equation:
[tex]f = \frac{343}{4* (0.49)}[/tex]
[tex]f = 175 hz[/tex]
Thus, the fundamental frequency of the flute is 175 hertz.
