Answer:
Step-by-step explanation:
126 mi/h = (126 mi)/(1 h)·(5280 ft)/(1 mi)·(1 h)/(3600 s) = (126·5280/3600) ft/s
126 mi/h = 184.8 ft/s = 924/5 ft/s
__
In 2 seconds, the parachutist falls ...
(184.8 ft/s)·(2 s) = 369.6 ft
We can use trigonometry to solve the problem. First draw a picture of the situation to understand what is going on (See the attached photo).
Next, we can use the tangent function to solve for the height of the building:
Next, rearrange the problem to solve for h:
h = 39.356 ft
Answer: 110kg
Step-by-step explanation:
To increase 100kg by 10% , we will just find 110% of 100kg, that is
110% x 100
1.1 x 100
= 110kg
