The swimming pool in an exclusive subdivision has 4 inlet pipes and one outlet pipe. The pool always has 250 cubic meters of
water in the bottom. If every inlet pipe brings in 25 cubic meters
of water per hour, and the outlet pipe drains 10 cubic meters per
hour, the relationship between the volume of water in cubic meters
V and the time in hours + when all the pipes are open is given by
V(1) = (4×25-10)t + 250 = 90% + 250 where + > 0. How much
time is needed for the pool to have 655 cubic meters of water?

In exponential growth functions, the base of the exponent must be greater than 1,how would the function change if the base of the exponent were 1? how would the fiction change if the base of the exponent were between 0and 1

Suppose that a customer is purchasing a car. he conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. he conducts this experiment 15 times on each car and records the number of miles driven. full data set car 1 238238 216216 205205 212212 240240 274274 297297 252252 260260 247247 257257 243243 296296 243243 290290 car 2 245245 204204 215215 209209 251251 165165 221221 295295 172172 287287 268268 305305 320320 260260 297297 describe each data set, that is determine the shape, center, and spread. sample mean for car 1 x overbar equalsx=216216 mi / 10 gal (type an integer or decimal rounded to one decimal place as needed.) sample mean for car 2 x overbar equalsx=209209 mi / 10 gal (type an integer or decimal rounded to one decimal place as needed.)
