X^2 - 18x - 144 = 0
Factorise:
We choose 2 numbers that add to -18, and multiply to 144, these numbers are +6 and -24, we put it into the brackets:
<span>(x + 6)(x - 24) <- x = the interted sign of the numbers inside the brackets
E.g. +6 turns into -6 and -24 turns into +24
x must = -6 or = +24
</span>
Let the event
The the probability of the events
The conditional probability
Answer:
Cot is the abbreviation of Cotangent. In mathematics, there are some functions called as the Trigonometric Functions, which used to relate the angles of a triangle to the lengths of the sides of a triangle.
I believe the answer is 32,500 days.
(7.8*(10^5)= 780000
Then you divide that by 24 and 32,500 is your answer
