Step-by-step explanation:
1/5
Answer:
20 meters
Step-by-step explanation:
Seeing the image attached, we can observe that there is a triangle formed by half of the chord of the arc, the radius (hypotenusa) and part of the radius (r-4). Using pythagoras theorem in this triangle, we have:
(r-4)^2 + 12^2 = r^2
r^2 - 8r + 16 + 144 = r^2
8r = 160
r = 20
So the radius of the circle that contains this arc is 20 meters.
Answer:
1.5 seconds.
Step-by-step explanation:
The height of ball modeled by the equation:
where, t is time in seconds.
The leading coefficient is negative, it means the given function is a downward parabola and vertex of the downward parabola is the point of maxima.
If a parabola is defined by
, then the vertex of the parabola is
In the given equation, a=-16, b=48 and c=100.
Vertex of the given parabola is (1.5,136).
Therefore, the maximum height of ball is 136 ft after 1.5 seconds.
