Answer:
Step-by-step explanation:
If the equation represents the position of the ball as a function of time then, to find in which second the ball reaches 120 feet must substitute in the equation of the height and solve for t.
If the initial velocity is 95 feet/s then
Then:
Use the quadratic formula
Where, for this problem:
So
<em>This result means that the ball reaches 120 feet for the first time at 1.8 seconds, then begins to descend and on its descent again reaches 120 feet at t = 4.1 seconds.</em>
Answer:
0.73
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of black cards = 26
Number of face cards = 12
Probability of drawing either a black or face card
Probability = required outcome / Total possible outcomes
P(drawing a black card or face card) = (number of black cards / total card) + (number of face cards / total cards)
= 26/52 + 12 /52
= 0.5 + 0.2307692
= 0.73
