Thanks!! Why does it turn into cos^2 θ off of 1 + sinθ?
The way I learned this was that you would have a certain amount of numbers. Like if there was 12, you'd have three groups: Q1, Q2(Median) and Q3. Generally, you're supposed to order the numbers from least to greatest, and then figure it out from there. It
The rule is to multiply each term by 6, do that and you'll get the answer!

I think option A is the best one, but the assessment says that B is correct. However, the lesson states that you can as long as each element(x) is different, you can have the same y value in the second column.
These are prime numbers, the next ones would be: 17, 19, 23, 29, 31, 37, 41, 43.
Is it C? All the f(x) values are different.
The information that I can provide is this: My current grade is: 88% My average quiz grade is: 95% A regular quiz counts for 15%, which isn't the highest of all assessments. These extra credit assignments are with 2%, but they have scores similar to 8/5
Is my probability correct?
Is this it? y^2 = 8x 8x = y^2 = 4px 8x = 4px 8 = 4p 8/4 = 4p/4 2 = p
I got this far: y^2 = 8x
How do I find the solution? Is 2 the solution?
I need to know what equation to use!
So, Mark would be correct. Those don't equal each other.
I believe that Mark is correct because if you were to square each value in the equation, you would have: (x+25) + (y - 49) = 49, not (x+5) + (y-7) = 7.
Right? I got that also. I used an online calc and I got 150 sqrt 33/11 to get x ~= 78.335!
I was told that the wind speed is 50, but I'm not sure how to get there.
Also, the trip is going to take 11 hours. I got a formula of: 11 = 2400/450+x + 2400/450-x I got 10.7 with decimals but any other help would be great.
I think it's Le! Is it @PsyDAG
