Answer:
12
Step-by-step explanation:
To find the perimeter, we must add together the length of each side.
The tick mark on the lines means they are equal, so that means we have two lines that are equal to 10
26 + 10 + 35 + 5 + 10 + (38 - 10) = 114"
Assuming the question marks are minus signs
to find max, take derivitive and test 0's and endpoints
take derivitive
f'(x)=18x²-18x-108
it equal 0 at x=-2 and 3
if we make a sign chart to find the change of signs
the sign changes from (+) to (-) at x=-2 and from (-) to (+) at x=3
so a reletive max at x=-2 and a reletive min at x=3
test entpoints
f(-3)=83
f(-2)=134
f(3)=-241
f(4)=-190
the min is at x=3 and max is at x=-2
Answer:
3
Step-by-step explanation:
An average railroad car has a weight of about 33 tons.
120 tons of freight is equivalent to 120/4 = 3.64 cars
that means that, for the operator to be able to haul 120 tons of freight, he has to haul at least 3 cars to break even.
Answer:
All you would do for this question is multiply 6 by 5.
6 • 5 = 30
Julissa had 30 oranges in all.
