Answer: 15/16
there are 15 scenarios in which you get at least 1 head and one where you don't therefore the answer is 15/16
Answer:
Algebraic, common difference = −9
Step-by-step explanation:
The first term of the series is 81, the second term is 72, the third term is 63 and the fourth term is 54.
So, the value of the terms decreases as the number of terms increases and this decrease in value is common and it is 9.
Therefore, the series is Algebraic series and the common difference is - 9. (Answer)
Note that
a² - b² = (a+b)(a-b)
i² = -1 by definition.
We want to factorize x² + 36 = x² + 6².
Consider the expression
x² - (6i)² = x² - (6²)(i²) = x² - 36i² = x² + 36
Because x² - (6i)² = (x + 6i)(x - 6i)
Therefore
x² + 36 = (x + 6i)(x - 6i)
Answer: (x + 6i)(x - 6i)
Answer: -1/2
Step-by-step explanation:
You want to find the equation for a line that passes through the points.
We use formula y2-y1/x2-x1
5-3/-2-2 = 2/-4
= -1/2
