I = 8.
k = 4
j = sqrt(8^2 + 4^2) = 8.944.
Work:
1) 11y - 3 = 13x
2) 11y = 13x + 3
3) y = 13/11x + 3/11

the only one that is the best way to go to last night I was wondering what the hell out the same thing happened in the next few weeks
Answer:
f(x) = - 9x² + 9
g(x) = 8x² + 9x
To find (f+g)(x) add g(x) to f(x)
That's
(f+g)(x) = -9x² + 9 + 8x² + 9x
Group like terms
(f+g)(x) = - 9x² + 8x² + 9x + 9
<h3>(f+g)(x) = - x² + 9x + 9</h3>
To find (f + g)(- 1) substitute - 1 into (f+g)(x)
That's
(f + g)(- 1) = -(-1)² + 9(-1) + 9
= - 1 - 9 + 9
<h3>= - 1</h3>
Hope this helps you
Answer:
II and III
Step-by-step explanation:
Causation always means coorelation, but corelation doesn't always mean causation.
Also, correlation is a two-sided relationship while causation is not. Hot days cause more ice cream sales but ice cream does not cause more hot days. However, hot days are correlated with ice cream and ice cream is correlated with hot days.
Therefore, only II and III are correct.
