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:
DE = 13.4 cm (to 1 decimal place)
Step-by-step explanation:
Given: ABCD is a square
BC = AC = 12 cm (opposite sides of a square are congruent)
E is midpoint of BC (given)
BE = EC = 12/2 = 6 cm
CD = AB = 12 cm (opposite sides of a square are congruent)
angle ECD is a right angle (interior angles of a square are 90 deg.)
Consider right triangle ECD
DE = sqrt(EC^2+CD^2) ............. pythagorean theorem
= sqrt(6^2+12^2)
= sqrt ( 36+144 )
= sqrt (180)
= 2 sqrt(45)
= 13.416 (to three dec. places)
Answer:
n = -5/13
Step-by-step explanation:
-8+4(1+5n)=-6n-14 (from PEDMAS, expand parenthesis first)
-8+1(4) +5n(4)=-6n-14
-8+4 +20n=-6n-14
-4 + 20n = -6n -14 (add 6n to both sides)
-4 + 20n + 6n = -14
-4 + 26n = -14 (add 4 to both sides)
26n = -14 + 4
26n = -10 (divide both sides by 26)
n = -10/26 = -5/13
