The answer is the first and the third figure,attached
Answer:
3 3/8 seconds.
Step-by-step explanation:
When it reaches the ground h = 0 so:
54t - 16t^2 = 0
16t^2 - 54t = 0
2t(8t - 27) = 0
t = 0 or t = 27/8 (we ignore the t = 0 ) so:
t = 3 3/8 seconds.
Answer:
w = .5
Step-by-step explanation:
-4w + 18w+2=10 -6w
14w + 2 -2 = 10 -2 -6w
14w + 2w = 8 - 2w + 2w
16w = 8
16w/16 = 8/16
w = .5
Answer:
Step-by-step explanation:
a. table
x = 100,y = 20*100+3000 = 2000+3000 = 5000
x = 200,y = 20*200+3000 = 4000+3000 = 7000
x = 300,y = 20*300+3000 = 6000+3000 = 9000
b:
y = 4300
4300 = 20x+3000
20x = 4300-3000
20x = 1300
x = 1300/20
x = 65
so 65 computer desks can be produced.
