Option (2) and Option (3) is the correct answer .
<u>Requ</u><u>ired</u><u> </u><u>Ex</u><u>plaination</u><u> </u><u>:</u>
Scenario 2 : The height of a stone shot by a catapult reaches a maximum height and then falls on the ground.
- The graph of this scenario is a downward parabola. Therefore option 2 is correct.
Scenario 3 : The sale of product increases at first and then decreases.
- The graph of this scenario is a downward parabola. Therefore option 3 is correct.

Answer:
745.4 cm^2
Step-by-step explanation:
The composite figure is made up of a rectangle 25 cm by 20 cm and a semicircle of radius 12.5 cm.
We add the two areas to find the total area.
total area = area of rectangle + area of semicircle
TA = LW + (1/2)(pi)r^2
TA = (25 cm)(20 cm) + (1/2)(3.14159)(12.5 cm)^2
TA = 500 cm^2 + 245.4 cm^2
TA = 745.4 cm^2
Answer:
Connect the two centers to produce the trend line
Step-by-step explanation:
When the dots have been plotted, there are three steps to find the trend line on a scatter plot:
1. Draw a vertical line that separates the full set of points into two sets, each with the same number of dots.
2.Mark with a special sign (e.g + or ×) the middle value in each of the two sets obtained in the previous step.
3.Join the two marks mentioned in the step (2) with a straight line, and extend it to the edges of the graph. This line is the trend line, and this is the last step.
Thus, the last step when using the divide-center method to find the line on scatter plot is Connect the two centers to produce the trend line.
Answer:
50%
Step-by-step explanation:
the increase is 60 so divide that by the original number; 60/120=0.5
now we have to change the decimal to a percent. multiply by 100 to do that and we get 50%.
