Answer:The numbers are already in standard form
Step-by-step explanation:
Answer:
X = 33,669.78 ft
Y = 15285.76 ft
Step-by-step explanation:
Given data:
let x be the distance btwn arch and plane
and y be the distance btwn ground point and arch y
we know that
xcos27 = 30000
x = 33,669.78 ft
b) we knwo that
y = tan(27) (30000)
y = 15285.76 ft
Let be the speed of train A, and let's set the origin in the initial position of train A. The equations of motion are
where are the positions of trains A and B respectively, and t is the time in hours.
The two trains meet if and only if , and we know that this happens after two hours, i.e. at
Solving this equation for v we have
So, train A is travelling at 105 km/h. This implies that train B travels at
C=11.27π feet
Diameter=11.27 feet. Hope it help!
