If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.
If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.
So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
It would be 6x5 squared-5x4+8
150-20+8=138
Answer: I'm pretty sure the correct answer is (B) Let me know if i'm correct!
Step-by-step explanation:
The answer to your problem is 2
Answer:
1/2
Step-by-step explanation:
The coin is balanced, so if we call p the probability of heads, then p must be equal to 1-p, the probability of tails. Since p = 1-p, then 2p = 1, therefore p = 1/2. As a consecuence, there is a probability of 1/2 that the number of heads obtained is 1, and a probability of 1/2 that the number of heads obtained is 0.
I hope this works for you!
