Answer:
x = 3 and -2 are the two solutions.
Step-by-step explanation:
2x^2 -2x -12 = 0
First factor out a 2
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0
2 = 0 x - 3 = 0 x + 2 = 0
2 does not equal zero so this is an extraneous solution
x - 3 = 0 so x = 3
x + 2 = 0 so x = -2
Answer:
The simplified version is P^21
Answer:
C. 1/25
Step-by-step explanation:
I assume this is a fair spinner and the probability of landing in all colors is equal.
First spin:
p(purple) = 1/5
Second spin:
p(purple) = 1/5
The two spins are independent events, so the probability of landing on purple twice is the product of the two individual probabilities.
p(purple and purple) = 1/5 * 1/5 = 1/25
Use the property of logs: a ln b = ln (b^a)
Also e and log are inverses, so the cancel each other
The answer is 1/2.
I got this answer by multiplying all of them.
3^0 = 1
1/2 * 1 = 1/2
