The function c(h)=(2h^2+5h)/(h^3+8) models the concentration of a medication in the bloodstream (as a percent), hours (h) after its injection into muscle tissue. a) suppose you need to readminister this injection at the point when the concentration is less than 0.5%. if the first injection was given at 8: 00 am, what time should the next injection be given?

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
