Answer:
hi:) search up "desmos calculator" and go to graphing. it will help solve all of the problems like this! hope I helped you!
Answer:
24.5m
Step-by-step explanation:
given h is proportional to v² or
h ∝ v²
we can write this in terms of constant k
h = kv²
given h = 8 when v = 20
h = kv²
8 = k 20²
8 = 400k
k = 8/400 = 0.02
hence our equation becomes
h = 0.02v²
when v = 35
h = 0.02 (35²)
h = 24.5 meters
2:3:1....added = 6
2/6(72) = 144/6 = 24
3/6(72) = 216/6 = 36
1/6(72) = 72/6 = 12
ratio is now 24:36:12
Answer:
Question 2 is y = 1/2 x - 2
Question 3 is y=-2x+4
Question 4 is y = x + 3
Your other questions don't have pictures of the graph so I can't solve them sorry. Have a good day.
answer TRUE because they would make a triangle
