A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following fun
ction:
f(t) = -16t^2 + 44t + 12
Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?
f(t) = -16t^2 + 44t + 12
Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?
2 answers:
Answer:
Domain is 1.375 s to 3 s
Explanation:
It is given that, A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function:
We have to find the domain of the graph of the function when the basketball falls from its maximum height to the ground. It is shown in the attached graph.
It is clear that, the domain of the graph is from 1.375 s to 3 s. Its maximum height is 42.25 feet.
Hence, this is the required solution.

<h2>Answer:</h2><h3>(A) the positively charged surface increases and the energy stored in the capacitor increases.</h3>
When charging a capacitor transferring charge from one surface to the other, the first surface becomes negatively charged while the second surface becomes positively charged. As you transfer the charge, the voltage of the positively charged surface increases and the energy stored in the capacitor also increases. We can solve this by the definition of <em>capacitance</em><em> </em>that is <em>a measure of the ability of a capacitor to store energy. </em>For any capacitor, the capacitance is a constant defined as:
To maintain constant, if Q increases V also increases.
On the other hand, the potential energy can be expressed as:
In conclusion, as Q increases the potential energy also increases.
