Answer:
Step-by-step explanation:
42+(1/3)
42*(3/3)+(1/3)
(126/3) + 1/3
126/3 + 1/3 = 127/3 miles
4/3 hours
(127/3)/4/3)
(127/3)*(3/4)
= 127/4 or 31.75 miles/hour
It would have been nicer if we were told Graham's distance after 1 hour (when he had travelled 31.75 miles).
Well, you know that the area of the rectangle is 12 square feet. And you know one of the numbers multiplied to get 12 is 5, so divide 12 by 5. You would get 2.4 as the other number needed.
In this case, 5 feet is the width and 2.4 feet is the length.
Let x = # of rent bumps
revenue = # occupants * rent per unit occupied
revenue = (170 - x) * ( 510 + 1.5*x)
in our problem, revenue (the money streaming in)
is the same as the profit, since no cost is given in the problem.
profit = (170 - x) * ( 510 + 1.5*x)
<span>to maximize this we use the derivative</span>
I got 25/21 or 1 4/21, but there’s a possibility I could’ve made a mistake in my math so you should double check it just in case.
Answer:
from difference of two squares:
hence proved
