X-intercept: -1
Y-intercept: -3
Use pythagorean theorem:
sin^2 + cos^2 = 1
(-1/3)^2 + cos^2 = 1
1/9 + cos^2 = 1
cos^2 = 8/9
cos = +- sqrt(8)/sqrt(9) = +- 2sqrt(2)/3
Determine whether cos is positive or negative by looking at which quadrant the angle is in.
pi < theta < 3pi/2 ---> this is 3rd quadrant where x or cos is negative
Therefore cos(theta) = -2sqrt(2)/3
Answer:
2(x^3-x^2-6)
Step-by-step explanation:
2 out of 2x^3 - 2x^2 - 12
Its been a slight while since I have done probibility, but from what I remember, I came op with the answer of a 2.3% probability that all of her friends would be able to come to the lunch she plans on the 4 different days.
The radii are 17 or less ( for 34pi) and 10 or more ( for 100pi)
