Answer: First option.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
Observe in the graph provided that the line intersects the y-axis at this point:
Therefore, the y-intercept is:
Let's check each option:
1)
Notice that:
2)
You can identify that:
3)
Observe that the y-intercept is:
4)
Notice that:
Therefore, the equation that most closely represents the line depicted in the graph is:
Answer:
22 seconds
Step-by-step explanation:
The maximum height is at the vertex of the parabola.
For a parabola y = ax² + bx + c, the vertex is at x = -b/(2a).
Here, a = -16 and b = 704.
t = -704 / (2 × -16)
t = 22
It takes 22 seconds for the projectile to reach its maximum height.
Answer:
Yes!
