Answer:
58
Step-by-step explanation:
the mean is adding up all the numbers, then dividing by the amount of the numbers.
add up all the numbers:
13 + 13 + 14 + 18 + 22 = 80
the mean is 23.
so you need to back track:
23 * 6 = 138
138 - 80 = 58
<span>Area = 9√3 = (a^2√3)/4
</span><span>Simplify
a^2=36
a=6 the side</span><span>a= 6 ft

Answer:
5.5 hours
Step-by-step explanation:
Since every house has an initial charge of $50, we can begin with that
($50)
Then, let's define h as the number of hours. We know every hour is $70, although the hours is yet unknown so that can be
($70 * h) or simply ($70h)
Now, we know the total should end up to be $435, so after PEMDAS the equation will be
($70h + $50 = $435).
We subtract 50 from both sides so now we have $70h = $385.
Now we divide both sides by 70, giving us h = 5.5. Hope it helped!
Answer:
The function f is graphed.
f is an even function as it has U- form.
As per the graph there is one local maximum at (0, 4) and one local minimum at (6, 1).
The global minimum is (-9, -2) and the global maximum is infinity.
The minimum and maximums are the borders of the increasing or decreasing intervals.
<u>Intervals when the function is increasing: </u>
<u>Intervals when the function is decreasing: </u>
