Answer:
A.
Step-by-step explanation:
Let be the equation of the perpendicular line.
Two perpendicular lines have slopes with product equal to -1. The slope of the given line is Hence,
is the slope of needed line.
This line passes through the point (-4,2), so its coordinates satisfy the equation:
Therefore, the equation of the line is
Answer
Find out the what is the acceleration of the object .
To prove
Formula
Where
t = the time in which the change occurs
As given
If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s .
Final velocity = 98 m/s
Intial velocity = 65 m/s
Time = 12 s
Put in the formula
Acceleration = 2 .75 m/s ²
Option (A) is correct .
