Given:
A line passes through (-5,-3) and perpendicular to .
To find:
The equation of the line.
Solution:
We have,
On comparing this equation with slope intercept form, i.e., , we get
It means, slope of this line is .
Product of slopes of two perpendicular lines is always -1.
Slope of required line is and it passes through the point (-5,-3). So, the equation of the line is
where, m is slope.
Therefore, the equation of required line is .
Answer:
Step-by-step explanation:
We are given that,
The fall of the acorn is represented by the function,
Equating S(t) to 0 gives,
i.e.
i.e.
i.e.
Since, time cannot be negative.
So, i.e. 1.25 seconds is the time when the acorn will reach the ground.
Thus, from the figure below, we see that,
The interval in which the acorn is in the moving air is .
