Answer:
V = 160mph
Step-by-step explanation:
We need to start from the formula of speed: V=d/t
We have two travels, with and against the wind, both done in the same time.
Clearing t from the formula, we will have: t=d/V2
450miles/V-35mph (speed of the wind is subtracted)
702miles/V+35mph (speed of the wind is subtracted)
Now, we find V:
450miles/V-35mph = 702miles/V+35
450*V+35 = 702*V-35
450V+15,750 = 702V-24,570
702V-450V = 15,750 + 24,570
252V = 40,320
V = 40,320/252
V = 160mph

Answer:
f^(-1)(x) = -3x/(3x-3)
Step-by-step explanation:
1) replace f(x) by y
● y = 3x/(5x+3)
2) exchange x and y
● y = 3x/(5x+3)
● x = 3y / (3y +3)
3) solve for y
● x = 3y / (3y +3)
● x (3y +3) = 3y
● 3xy + 3x = 3y
● 3xy - 3y = -3x
● y (3x - 3) = -3x
● y = -3x /(3x-3)
4) replace y with f^(-1)(x)
● y = -3x/(3x-3)
● f^(-1)(x) = -3x/(3x-3)
Answer:
that is the solution to the question
A = ((B+b)*h)/2
A = ((6+4)*3)/2
A = 15
