Asmoke jumper jumps from a plane that is 18001800 ft above the ground. the function h equals negative 16 t squared plus 1800h=â16t2+1800 gives theâ jumper's height h in feet during the free fall at t seconds. a. how long is the jumper in free fall if the parachute opens at 1000â ft? b. how long is the jumper in free fall if the parachute opens at 950950 âft? c. what is a reasonable domain and range for the functionâ h? a. the jumper is in free fall for nothing s if the parachute opens at 1000 ft. â(round to two decimal places asâ needed.)

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
