What is the answer to __+6=__+7

Function h(t) = sin (t) cos(pi/6)+sin(pi/6)cos(t) represents height of a wave in an ocean, where h, is height in meters, and t, is time in seconds. Determine all values of time when height of this wave is 1/√2 meters.

If h(x) = log(x) -2log(x-1), and h(x) can be written as h(x) = f(g(x)), determine functions f(x) and g(x), where neither of them are linear functions.

F=ma ( Newton = kg*(m/s^2) ) When you multiply the mass (in kilograms) of an object by how much it's being accelerated, you'll get how much force (in Newtons) it's exerting.

There's also plenty of links on the bottom of the Wikipedia article under "External Links".

5+2(x-1) = 0 5+2x-2 = 0 5+2x = 2 2x = -3 x = -3/2 (which is -1.5)

x = time (independent) y = distance (dependent) horizontal: y isn't changing diagonal: y is increasing at a constant rate

5+2(x-1) = 12 5+2x-2 = 12 5+2x = 14 2x = 9 x = 9/2 (which is 4.5)

hi, is that all for a? please let me know, thank you Maya

thank for you so much steve!!! i just wanted to double check.. for (a) it is y' = - (y+5x^4y^2+9x^2)/(x+2x^5y) i was wondering if the last part of it (x+2x^5y) is it 2x^(5y) or 2x^5(y). im not sure if the "y" is in the exponent or not.

thank you for taking your time to answer my questions steve!

ok so the final answer would b a) y' = -(y + 5x^4y^2 + 9x^2)/(x+2x^5y) and b) y' = -y sin x thank you SO much once again steve, my exam is in a couple of hours and this solution really helped me, im very thankful. thanks so much!!

You would add up all the numbers in the survey, then subtract that number by the number of people surveyed to get your answer.

pry, or coax — certainly not "delude"

1 and 2 are acceptable; 3 is ambiguous.

Well, I don't know what "…test for his logic." means; but, none of the "senses" you mention are evident.

Yes,; but, I don't much like "conducting" an analysis.

In what language, please?

What's the question, please?

Yes. The difference of their ages is the key.

Yes. Perhaps "blemish" would be a better choice.

"… I felt much better."

"passages" is plural, hence the plural of the "is" verbs.
