How do you solve f(x) ?
Talja [164]
F (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one"). In either notation, you do exactly the same thing: you plug –1 in for x, multiply by the 2, and then add in the 3, simplifying to get a final value of +1

A man weighing 80 kg gets into an elevator. The elevator starts moving upward with an acceleration of 2 m/s2. What is the reacti
maria [59]

The reaction force exerted by the floor of the elevator on the man is D.944 N

Step-by-step explanation:

When the elevator is accelerating upwards at 2 m/s² there occurs a fictitious force acting downwards to produce a downward acceleration of 2 m/s².

The formula to apply here is ;

Weight due to gravity=mg where m is mass of the man and g is acceleration due to gravity.

Due to additional downward acceleration the total acceleration downwards will be : 9.8+2 = 11.8 m/s²

The man weighs down on the elevator floor with a force of ;

F=m(a+g) where m is mass of man, a is acceleration

F=80( 9.8+2)

F=80(11.8)= 944 N

The reaction force by the floor of the elevator is thus 944 N
