Answer:
Step-by-step explanation:
Factoring an expression is the process of undoing the multiplication.
Assume you have a function f(x):
This can be factored:
Using multiplication and the distributive property, you arrive back to:
Then you can see clearly that all we've done is reverse the multiplication.
Answer:
18 ft
Step-by-step explanation:
Convert yards to feet:
6 yds 3 ft
------------ * ------------ = 18 ft
1 1 yd
Disregarding air friction, the distance traveled by an object due to gravity is : H = 0.5*g*t^2. g is the gravitational constant at the surface of earth.
g= 9.81 m/s^2
After 3 seconds, Distance = .5*9.81*9 = 44.15 meters traveled.
Since it was dropped from a height of 90 meters, the current height is 90 - 44.15 = (a) 45.85 meters
(b) It has to travel 90 meters to hit the ground . So we must find t
Using the same equation
t = (2*H/g)^.5
t = (2*90/g)^.5 = 4.28 seconds until it hits the ground
