During this month I have had 5 dreams with my deceased father in them. He's never ever come into my dreams before and this month he randomly did 5 times. I know it's called "dream visitation", but is it really him? Is it him or his spirit? Or is it me just simply dreaming/thinking of him without realizing it?

I am finishing up trig in college and I'm about to sign up for the next semester. Is it safe to skip precal and go straight to calculus?

I am not a math whiz, but I'm not totally lost either.

i was given this problem:

1/4 = 3 - ((2x-1)/(x+2)) and solve for x:
i get x = -8.666 but it doesnt check out right when i plug it back into the original equation for x.
can someone tell me what x is?
and show me how they came to that answer?

the question is -2 to the 0 power -3 to the 0 power (-2 - 5 to the 0 power) - 1/-2 to the -2 power + x to the 2 power * y - xy if x = -2 and y = 3

I don't get it the 0 powers are messing me up.

An air puck of mass 0.25 kg is tied to a string and allowed to revolve in a circle of radius 1.0 m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table, and a mass of 1.0 kg is tied to it. The suspended mass remains in equilibrium while the puck on the tabletop revolves.

(a) What is the tension in the string?

(b) What is the horizontal force acting on the puck?

(c) What is the speed of the puck?

2. Determine the slope of the line that passes between the two points you’ve selected. (Hint: To set up points, let January of 05 be month 1, February of 05 month 2, and so on.) (3 points)
3. Substitute the coordinates of one point and the slope you calculated in step two into the point-slope equation of a line: y – y1 = m(x – x1).
Solve for y to get the form: y = mx + b. (3 points)
4. Clearly state what your variables represent. (Note: the collaborative investigation on page 459 might be helpful to develop a linear model.) (3 points)
5. Use your model, the equation you’ve developed, to predict the CPI for the next month. (3 points)

I have been studying the behaviour of both species and they both appear to be excessively hairy and prone to sudden and unexplained suicidal urges. I feel sure there must be a common ancestor.
