The charges on a monthly water bill came to $0.86 per cubic meter of water used, plus a service charge of $4.49. Last month Jeremy's water bill came to $69.85, how many cubic meters of water had he used?
The velocity v of a freefalling skydiver is well modeled by the differential equation m*dv/dt=mg-kv^2 where m is the mass of the skydiver, g is the gravitational constant, and k is the drag coefficient determined by the position of the driver during the dive. (a)Find the gener...
Find the general solution of the differential equation specified. 1) dy/dt= 1/(ty+1+y+1) 2) dy/dx=sec y I got y(x)=arcsin(x) for the second one. I'm not sure what to do with the first one.

A rocket is launched from ground level with an initial vertical velocity (v0) of 176 ft/s. After how many seconds will the rocket hit the ground? (Hint: h(t) = -16t2 + v0t + h0)
A beverage comopany uses a machine to automatically fill 1-liter bottles. Assume that the population of volumes is normally distributed. The company wants to estimate the mean volume of water to within 1 ML. Determine the minimum sample size required to construct a 95% confide...
A survey of adults found that 35% say that their favorite sport is professional football. You randomly select 120 adults and ask them if their favorite sport is professional football. Find the probability that more than 30 people answer yes.
Elena, why do you have a 13 & 23 beside F? Or is this just to distinguish between the two forces
