What is the union of the two sets A={2,3,6,11,16} and B={6,11}? A. {2,3,6,11,16} B. {2,3,16} C. {6,11} D. {16}
Katarina [22]
Union is everything in the two sets together, so the union would be:
{2,3,6,11,16} (B is a subset of A so there is no difference)
The answer is A.
Should be 61 cm but you can double check
Answer:
Step-by-step explanation:
Just add the numerators and that will equal 6 and then x^2 will remain the same.
Answer:
c
Step-by-step explanation:
To find the maximum point, differentiate:
D' = -8p +160
Set to zero and solve for p:
D' = 0
⇒ -8p +160 = 0
⇒ 8p = 160
⇒ p = 20
Input p = 20 into the original equation to find D:
D = -4(20)² + 160(20) -310 = 1290
Therefore, the price is $20 and the maximum number of drills is 1,290
