<h3><u>Answer</u> :</h3>
Let numerator of fraction be x and denominator be y.
∴ Fraction = x/y
★ <u>Part - A</u> :
★ <u>Part</u><u> </u><u>-</u><u> </u><u>B</u> :
From equation (1)...
∴ Fraction = x/y = 3/8

im sorry this question doesnt make sese you cant have a slope represented by points on a graph
( such as (6,-5)
Find how fast she runs 1 km:
18/2 = 9 minutes.
So we know have K = 9t
Subtract 18 from both sides:
K-18 = 9t -18
Rewrite the right side:
K-18 = 9(t-2)
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
