Put the number over each the total that was added then, divide the bottom number to into the top number
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
Answer:
Angle 8
Step-by-step explanation:
Refer to the attached picture
Answer:
no even if it was up agains the wall you would still be 10 feet from the top
Step-by-step explanation:
the end behavior is that it goes positive and both ends (we look at x^4 ) and put in -inf and + inf and get +inf both times)
to get the y intercept let x=0 y intercept =144
to find the x intercepts we factor and find the zeros
using graphing technology we plot the function
we look at the ends of the graph if it goes down it goes to - inf, if it goes up it goes to + inf
the y intercept is where x=0
there x intercepts are where it crosses the x axis on the plot (there should be 4 unless some are imaginary)
