If F = { (1,2), (3, 5), (4,7)} and G = { (1,4), (3,0), and (5, 2)}, what is F + G? What is F\G (using function arithmetic)?

Answer:
Step-by-step explanation:
From our knowledge of composite function, we first determine the intersection point of the F and G on the x coordinate which when compare the domain point 1 and 3.
To carry out the operation F+G we only perform this operation on the y-coordinate that has the same x-coordinate and this point occur only at point 1 and 3 as stated earlier.
Hence
Also for the division F/G we have
(3,undefine)
since at point 3 we have the y coordinate not define. this simple mean that we an asymptote at x=3
You have to find the square root
Answer: The answer is (b) 100° C.
Step-by-step explanation: Given that Bobby's mom sets a small small pot of water on the stove and lights the burner, which after ten minutes bobby notices boiling. We nee to choose the correct temperature of the water among the four given options.
We know very well the freezing and boiling point of water, which are 0° C and 100° C. And at 100° C, the water starts vapourising.
Since the water was boiling when Bobby notices the pot, so the temperature of the pot must be 100° C.
Thus, the correct option is (b) 100° C.

Answer: D. 3</h3>
This is a 30-60-90 triangle. The shortest leg (opposite the smallest angle) is half that of the hypotenuse, so y = 6/2 = 3.
Extra info: The long leg is sqrt(3) times the short leg, so x = y*sqrt(3) = x = 3*sqrt(3)
