Answer:
(6y - 1)(6y + 1)
Step-by-step explanation:
To factorize completely, we may adopt the difference of 2 squares approach. The theory states that difference of two square is the product of the difference of the number and the sum of the numbers.
Such that
a² - b² = (a - b) (a + b)
Hence 36y² - 1
= 6²y² - 1²
= (6y)² - 1²
= (6y - 1)(6y + 1)
Just do for example on number 38 you will do 6.8/1000= 0.0068 which is the answer
Answer:
Step-by-step explanation:
2x²-13x+21+6x²+29x-5
=8x²+16x+16
Answer:
$-107
Step-by-step explanation:
From the problem we know the probability of randomly selecting a person alive throughout the year: 0.9989
Now, the probability that a person does NOT live would be the complement, that is:
1 - 0.9989 = 0.0011
Now to know the real value of the policy, we must first subtract what he paid for it, that is:
80000 - 195 = $ 79805
Now, to know what the value waiting for that person would be the subtraction of the real value that will be gained by the probability of not living, less what the policy payment for the probability of surviving, thus:
0.0011 * 79805 - 0.9989 * 195 = -107
Which means this man is actually losing $ 107
Answer:
d. 0.85m + 2.50
Step-by-step explanation:
In the figure attached, the complete question is shown.
We can see in the table that $2.50 is a fixed charge, that is, it is not modified by any variable. On the other hand, for each travelled mile, the cost of the travel increases $0.85 ($0.75 by mileage charge + $0.1 by city gas tax). Then, if m miles are travelled, the cost of the travel increases 0.85*m
