8.712r + 1= (1+r)^10 Solve for r.

Of course I can just use guess and check, but where's the elegance in that?

I’m thinking about becoming a radiologist. I’m only starting my first year of community college. But it looks like a very interesting profession. And I think I have the brain power to achieve it. Can you tell me what your normal day at work is like. And what exactly you do in those processes. And if you could do it all over again would you stay in the same field? Or maybe go in a different branch.

I know the formulas y-y1=m(x-x1)
and
y2-y1
-------
x2-x1

The questions are

1. Is parallel to 2x+3y=8 and passes through (5,4)

2. Is perpendicular to y= - 1/2x+3
and has a y-intercept
of -2

I can do other question using this formula but these are giving me a hard time.

11) C2H2 is made from adding water to CaC2.

CaC2 (s) + 2H2O (l) >>>>C2H2 (g) + Ca (OH)2 (aq)

How many Grams of acetylene are produced by adding water to 5.00 g CaC2?

12) using the same equation, how many moles of CaC2 are needed to react completely w/ 49.0 g H2O?

A car starts from rest and accelerates to a final velocity in two stages along a straight road. Each stage occupies the same amount of time. In stage 1, the magnitude of the car's acceleration is 3.0m/s^2. The magnitude of the car's velocity at the end of stage 2 is 2.5 times greater than it is at the end of stage 1. Find the magnitude of the acceleration in stage 2.
