Answer:A
Step-by-step explanation: A is 8d+d, and since d=1, 8d,+1d is equal to 9d
The estimate between 2 and 9 is 7
Based on the given graph, the time when the softball reaches its maximum height is about 1.8 seconds.
<h3>When is the softball at it highest?</h3>
The softball is at its maximum height at the point where the curve begins to go back down.
This means the maximum height is 50 feet.
The time when this softball reaches this height is between 1 and 2 seconds at 0.8.
The time the softball reaches its maximum height is therefore 1.8 seconds.

<span>Volume of the Sphere V = 4/3pi x r^3
So when diameter d = 3 inches => r = 1.5 inches
volume of the sphere = 4.188 x r^3 = 4.188 x 1.5^3 = 14.14 in
So when diameter d = 8 inches => r = 4 inches
volume of the sphere = 4.188 x r^3 = 4.188 x 4^3 = 268.03 in
So when diameter d = 9 inches => r = 4.5 inches
volume of the sphere = 4.188 x r^3 = 4.188 x 4.5^3 = 381.63 in
value for option (a) is 3 x 14.14 = 42.42 inches
value for option (b) is 268.03 inches
value for option (c) is 381.63 / 2 = 190.815 inches
So the correct option would be (b)</span>
