Answer/Step-by-step explanation:
6. Given, (-5, 2) and (1, -2):
9. Given, (4, 10) and (-2, -5):
Step-by-step explanation:
There are four odd number between 1 and 7:
1, 3, 5, 7
So the probability that a randomly selected ball is an odd number is 4/7.
The answer is B reflection across the y axis
About 176.4 is what i had gotten but i would still check out the other persons answer and compare
Notice that
(1 - <em>x</em>)⁵ (1 + 1/<em>x</em>)⁵ = ((1 - <em>x</em>) (1 + 1/<em>x</em>))⁵ = (1 - <em>x</em> + 1/<em>x</em> - 1)⁵ = (1/<em>x</em> - <em>x</em>)⁵
Recall the binomial theorem:
Let <em>a</em> = 1/<em>x</em>, <em>b</em> = -<em>x</em>, and <em>n</em> = 5. Then
We get an <em>x</em> ³ term for
2<em>k</em> - 5 = 3 ==> 2<em>k</em> = 8 ==> <em>k</em> = 4
so that the coefficient would be
