Answer:
Step-by-step explanation:
D = {x | x is a whole number}
D = {0, 1, 2, 3, 4,......}
E = {x | x is a perfect square between 49 and 100}
E = {64, 81}
F = {x | x is an even number between 10 and 20}
F = {12, 14, 16, 18}
D∪F = {x | x is whole number}
D∩F = {x | x is an even number between 10 and 20}
D∩E = {x | x is a perfect square between 49 and 100}
E∩F = {null set}
D∩(E∪F) = {12, 14, 16, 18, 64, 81}

Step-by-step explanation:
Answer: 38080 feet cubed
Step-by-step process:
60ft × 45 1/3ft = 2720ft squared
2720ft squared × 14ft = 38080 feet cubed
Answer: 12
==============================
Explanation:
Multiply the corresponding coordinates of the vectors
4*11 = 44
1*2 = 2
5*(-6) = -30
Then add up the results: 44+2+(-30) = 42-30 = 12
The dot product of two vectors is always a scalar value.
