Science and medicine. Find the time required for an object to fall to the ground from a building that is 1400 ft high.
using the formula : t = (1)/(4) radical (s)
My answer: t = 9.35 (but i don't know how to word it if minutes all or minutes and seconds etc......)
Use the properties for radicals to simplify each of the following expressions. Assume that all variables represent positive real numbers.
My answer: (radical (15))/(3)
MY answer: (2xradical(15x))/(5)
t=9.35 minutes means
9 minutes plus .35 of the next minute, there are 60 seconds in a minute, so multiply the .35 by 60 for 21 seconds
so the time is 9 min, 21 seconds
for the last part, where did the 15x come from?
my answer was 2xsqr(3x)/5
how did you do the second problem to get that answer. maybe i made a mistake.
you had written
do you mean it should read
2 times x times radical 3x/5
