ok the coordiantes are (-1,0) (-5,6) i think the slope is -1.5 and i think y = -1.5x + (-1.5)
but i think i am wrong

The Chin's Family cottage is 72mi away from their city home. Due to road construction Mrs Chin can drive 30mph faster going to the cottage than she can returning to the city. Given that the trip takes 2 hr, what is Mrs Chin's speed when driving from the cottage to the city?

I have been working on this forever and I just can't figure it out..

But I do not know how to find out more about it as the only possible thing I can get is an image through a photo if I do take a camera. Are there such specific search engines? Like searching birds/plants through their features/images etc?

A dive bomber has a velocity of 280 m/s at angle 'theta' below the horizontal. When then altitude is 2.15 km, it releases a bomb, which subsequently hits a target on the ground. The magnitude of displacement from the release of the bomb to the target is 2250m, find theta.

I usually do not ask from homework help, but I have been working on this one for a while and I am still not sure how to approach it. Thanks everyone.

I need to find the molecular wieght of potassium aluinum sulfate dodecahydrate (I would type the formula, but I'm not sure how to get it in here. Hopefully that is enough info). What does dodeca mean for one thing.

What I think I am confused about is that in the balanced equation (which is all they give of the molecular formula) there are two of one molecule and 12 waters. Should I reduce that? How many atoms are actually in the molecule?

Sorry my question is not very clear. I'm not even sure what I'm asking, but I know I am totally lost (and I hate chemistry...) Any help would be great.

, the coordinates are (2,2) (3,4)..the slope of them is 2. Now i know this equation: y=mx+b. i think i am suppose to find the y intercept or i am suppose to find b. im not sure and i dont know how to do either

Let 0
You are not suppose to solve the values, because you cant.

f(x)=4sin(3x+pi)

Amplitude: 4
Period: ?

I had put 2pi/3 + pi = 5pi/3
^^how i got that i have no idea....but anyways, my teacher found it necessary to circle the 2pi/3 part....any insights? thanks :-)

Does the speed of a falling object depend on its mass? What about the speed of a satellite in orbit?
