A interesection B means similarities between the two sets.
The possible values you can get in B are:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
A:
3, 5, 7, 9, 11
Therefore A intersection B = {3, 5, 7, 9, 11}
Answer: b
Step-by-step explanation:
x=12
12+5=17
3 times 12 is 36+10=46
46+17=63
12+51=63
They are both 63
Answer:
C. (1, –2); minimum
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The vertex is the turning point of the graph.
This is at (- 1, - 2)
The graph changes from decreasing to increasing at (- 1, - 2)
Hence is a minimum at (- 1, - 2)
I think the answer is: r=13/16
