Answer:
f(x) = 2^x
ln f(x) = ln 2^x
ln f(x) = x ln 2
Step-by-step explanation:
Step-by-step explanation:
we simply need to get the total distance and the total time and put them into relation, norming it to distance in 1 hour. after all, speed is always an average number over a period of time (even if it is a tiny period of time).
the total distance is
72 + 69 = 141 km
he drove 69 km going 60 km/h.
how much time did he need ?
we need to get the hours out of an expression of km and h.
so, we need to do
69 km × 1/60 km/h = 69 h / 60 = 69 minutes = 1.15 hours =
= 1 h 9 minutes
so, the total time was
48 + 69 = 117 minutes = 117/60 = 1.95 hours
the average speed for the whole trip was then
141 km / 1.95 h = 141/1.95 km / 1 h = 72.30769231... km/h
If 60% out of the 2,660 students are males, then
40% out of t<span>he same 2,660 students are females
Ten the number of females is 40% x 2660 = 0.4 x 2660 = 1,064 females</span>

8000 paperclips = 8kg
Answer:
x = 2
Step-by-step explanation:
3(x - 4) = 2x - (6 + x) first get rid of parenthesis
3(x - 4) = 3x - 12 and
2x - (6 + x) = 2x - 6 - x
3x - 12 = 2x - 6 - x
3x - 12 = x - 6 export like terms to the same side
3x - x = 12 - 6
2x = 6 divide both sides by 2
x = 3
