Answer:
From what height did the parachutist jump?
914 m
Explanation:
v = 58.8 m/s
u = 0 m/s
a = 9.81 m/s^2
t = 6.00 s
v^2 = u^2 + 2as
58.8^2 = 0 + 19.62s
s = 3457.44/19.62 = 176.22m
Upon decelerating after opening parachute;
v = 10 m/s
u = 58.8 m/s
t = 4.00
deceleration =( 58.8 - 10)/4.00 = 12.2 m/s^2
v^2 = u^2 + 2as
100 = 58.8^2 - 24.4s
3357.44/24.4 = s
s = 137.6s
Upon decending at constant velocity
distance = time*velocity = 10.0*60 = 600 m
Initial height = 600 + 137.6 + 176.22 = 913.82 m = 914 m
Answer:
C. display
Explanation:
Display advertising is an advertising process where a product or services are displayed in form of images, videos, and published on the social sites so that the people could aware of that particular product or services
Therefore as per the given situation, in the newspaper advertising, the display advertising involved the copy, photos, headlines etc
Hence, the correct option is C.
Answer:
$1,250
Explanation:
The computation is shown below:
Customer life time value = Gross contribution margin × (yearly retention rate ÷ 1 + yearly discount rate - yearly retention rate)
= $500 × (0.8 ÷ 1 + 0.12 - 0.80)
= $400 ÷ 0.32
= $1,250
The gross contribution margin would be
= $1,000 - $500
= $500
hence, the estimate for the lifetime value os $1,250
