we know that
this is the equation of a line, to identify which is the graph we will proceed to determine the points of intersection with the coordinate axes
1) <u>Find the y-intercept</u>
the y-intercept is when the value of x is equal to zero
For
find the value of y
2) <u>Find the x-intercept </u>
the x-intercept is when the value of y is equal to zero
For
find the value of x
therefore
the answer is the option B ( see the attached figure)
Answer:
2.5 second
Step-by-step explanation:
The equation is missing in the question.
The equation is, , where 'h' is the height and 't' is time measured in second.
Now we know to reach its maximum height, h in t seconds, the derivative of h with respect to time t is given by :
Now the differentiating the equation with respect to time t, we get
For maximum height,
So,
Therefore, the ball takes 2.5 seconds time to reach the maximum height.
