Answer:
Work individually or in teams of two to construct and launch paper rockets using a teacher-built PVC-pipe launcher.
Following the flight of their rocket, calculate the altitude their rocket achieved.
Based on the flight performance of their rockets, analyze their rocket designs, modify or rebuild them, launch again, and calculate the altitude achieved to determine if their changes affected the performance of the rocket.
Conclude the activity by writing a post-flight mission report.

Answer:
Option C is the correct answer.
C. 5•(-20)
Step-by-step explanation:
We are told that the insurance payment for the car follows a certain pattern that can be represented through an expression. The payment is decreasing by $20 every year. As we don't know the total payment amount per period, so we cannot calculate how much is paid per period/year for insurance but we can calculate the rate at which this payment is decreasing.
Change in payment = t * (-20)
The above expressions can be used to calculate the amount of change in payment i payment is decreasing by a constant $20 every year, after t years.
So, if we want to calculate the change in payment after say 5 years, we can replace t with 5 in the equation and calculate the change,
Change in payment = 5 * (-20)
Change in payment = - $100
The answer of the data set is 22
The given points are (4,8) & (9,-4)
slope of a line = <u>Y2 - Y1</u>
X2 - X1
====> <u>(-4) - 8</u> = <u>-12</u>
9 - 4 5
Answer:
x = 50.60 cm
Step-by-step explanation:
Given triangles ΔMAB and ΔMNP are smilar accordingly their corresponding sides are proportional.
But first we will determine the size of the side MA:
MA = MN - AN = 46.2 - 14 = 32.2 cm
Now we will make proportion:
MN : MA = MP : MB => 46.2 : 32.2 = 72.6 : x
When we multiply external and internal members we get:
46.2 x = 72.6 · 32.2 => x = 72.6 · 32.2 / 46.2 = 2337.72 / 46.2 = 50.60 cm
x = 50.60 cm
