Consider a function that descnbes how a particular car's gas soleage depends on its speed What would be a appropriate domain for this function? 0 to 100 miles per hour 0 to 50 miles per gallon times from 0 to 10 minutes times from 10 to 10 minutes

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

5 feet of chain cost $9

so the answer is 1.80
