The formula can be used to find the velocity v in feet per second of an object that has fallen h feet. Find the velocity of an o
Mama L [17]
The formula for a falling object is
v = u +gt
where
u =  initial velocity (=0 for a falling object)
g =  acceleration due to gravity, 32.2 ft/s²
t = time, s

In terms of distance fallen,
v² = u² + 2gh
where h =  distance fallen, ft.

Because h = 23 ft and u = 0, therefore
v² = 2*32.2*23 =  1481.2
 v = 38.486 ft/s

Answer: 28.49 ft/s (nearest hundredth)

Solve the following exponential equations.<br> 2(4^x )+ 4^(x+1 )= 342
Cloud [144]

Answer:

  x ≈ 2.91644500708

Step-by-step explanation:

The equation can be simplified to ...

  2(4^x) +4(4^x) = 342

  6(4^x) = 342

  4^x = 57

Taking logarithms, we get ...

  x = log₄(57) = log(57)/log(4)

  x ≈ 2.91644500708
