Max visits his friend Alona and then returns home the same route. He has taken this trip 32 times and has used his fitbit to record the information. Although there is some variance, he basically bikes 6 mph going uphill, 12 mph when going downhill, and 8 mph on level ground. Find the total distance he bikes if the total biking time of a trip is 6 hours.

If he wants to cut down his total travel time by 1 hour, what speeds would he have to travel at uphill, downhill and on level ground?

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)

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
