The graph that does not show Y or X
EXPLANATION:
1.25 + 0.8 + 2.75 = $4.8
ANSWER: $4.8
Answer:
They are all correct.
Step-by-step explanation:
1.
1/2(b)(h)
1/2(4)(6)
1/2(24)
12
2. l x w
7 x 5
35
3. (b)(h)
(8)(4)
32
The acceleration due to gravity on earth is g = 32.174 ft/s².
Therefore on Mars,
g = (2/3)*32.174 = 21.45 ft/s²
When an object falls from rest over a distance h, the final velocity, v, obeys the equation
v² = 2gh
or
v = √(2gh)
Therefore, given h = 15 ft, the impact velocity on Mars is
v = √(2*21.45*15) = 25.367 ft/s
The closest given answer is 25.3 ft/s
Answer: B) 25.3 ft/s
