Concave up is U-shaped.
There will be a inflection/critical point f'(x) =0 then a negative slope f'(x) = neg then another inflection/critical point f'(x) =0 at the bottom of the U-shape then a positive slope to last inflection/critical point. The interval for the Concave Up shape is the first and last inflection points.
Answer:
A
Step-by-step explanation:
2 and 4 are on opposite sides of the transversal but both on the inside of the parallel lines. This makes them alternate interior angles, which are congruent.
Answer:
30 waiters
Step-by-step explanation:
the ratio of 5 waiters to 2 cooks
you are given the total number of waiters and cooks = 42
write equation
x (5 + 2) = 42
7x = 42
x = 6
now distribute the x into waiters which is 5x or 5(6) = 30 waiters
additionally 2x is for cooks or 2(6) = 12 cooks; which adds up to 42
You would find the multiples 2 and 3 had in common
so may 6th, 12th, and 18th
2: 3:
4 6*
6* 9
8 12*
10 15
12* 18*
14
16
18*
