Given the <span>frequency distribution for a bowl of coins containing 3 quarters, 5 dimes, 2 nickels and 8 pennies.
The raw data containing </span>3 quarters, 5 dimes, 2 nickels and 8 pennies is <span>QPNDPPPQDPNPDPDQPD.
Therefore, the set of raw data corresponding to the given frequency distribution is the raw data in option A.</span>
Answer:
- maximum current: 7
- time to reach maximum: 1
Step-by-step explanation:
The equation can be rewritten to vertex form to find the maximum value:
I = -5(t^2 -2t) +2 . . . . . . factor leading coefficient from variable terms
I = -5(t^2 -2t +1) +2 -(-5(1)) . . . . . add and subtract the square of half the t coefficient
I = -5(t -1)^2 +7 . . . . . . write in vertex form
The vertex of the graph is at (t, I) = (1, 7).
The maximum current of 7 is reached at t=1.
