Answer:
(-9, 3)
Step-by-step explanation:
To rotate a point 270°:
R₂₇₀ (x, y) = (y, -x)
So the answer would be (-9, 3).
Points Q and R are on a horizontal line (y=2), and point S is off to the left of both of those. The triangle is ...
... B. The tirangle is an obtuse scalene triangle.
Answer:
2/5
Step-by-step explanation:
There are 10 marbles and 4 of them are purple. That would give you the fraction 4/10. 4/10 can be simplified to 2/5. So, you have a 2/5ths chance of choosing a purple marble.
Simplify the integrand:

Now integrate one term at a time.



Putting everything together,
