Answer: You would need to buy 1320 tickets to guarantee a win.
In a trifecta race, you have to select the correct 1st, 2nd and 3rd places in order.
Therefore, the number of possibilities would be:
13 x 12 x 11 = 1320
Answer:
Step-by-step explanation:
Several trig identities are involved in the proof of this. This is the order in which they are used.
- cos(2x) = cos²(x) -sin²(x)
- cos²(x) +sin²(x) = 1
- cos(x) = 1/sec(x)
<h3>Proof</h3>
Starting with the left side, we can transform it into the right side.
Answer:
1234567890
Step-by-step explanation:
Each of the digits is divisible by their individual index in the number. Adding a 0 at the ends allows for the number to be divisible by 10 and completes the 10 digit requirement.
