Answer:
0 <=t<=21
Step-by-step explanation:
Projectile is Moving upwards on an interval of (0 to 21), if we plot Velocity vs Time and denote positive y-axis above 0 and negative y-axis below 0(for velocity), then from 0 to 21 t projectile is moving upwards and has positive velocity, when the projectile reaches the top of it's motion and returns back down to ground it's velocity is negative and is plotted below the y =0 (note that is for t > 21).
hence for the interval 0 <=t <=21 the instantaneous velocity is positive (Note, instantaneous velocity is also the derivative of the velocity or the slope ).

Answer: The y intercept is -7 or (0,-7)
Step-by-step explanation:
First convert the equation into slope intercept form .
y - 3 = -2(x + 5) Multiply on the right side
y -3 = -2x - 10 Add 3 to both sides
+3 +3
y = -2x - 7
In this case the y intercept is -7 and it is when x is zero.
