Answer:
15.5 cm
Step-by-step explanation:
You want the difference between the values of x that make y=0. Solving for those values, we get ...
0 = -0.1(x -1)^2 +6
0 = (x -1)^2 -60 . . . . . . . . . multiply by -10
60 = (x -1)^2 . . . . . . . . . . . add 60
±√60 = x -1 . . . . . . . . . . . . take the square root
At this point, it should be obvious that the difference between the two solutions will be 2√60 = 4√15. If it is not, we can find the two solutions and take their difference:
x1 = 1 +√60
x2 = 1 -√60
Then the difference is ...
x1 -x2 = (1 +√60) -(1 -√60) = 2√60
60 has a square factor (4), so we can simplify this radical to ...
x1 -x2 = 4√15 ≈ 15.4919 ≈ 15.5
The ends of the rainbow are about 15.5 cm apart.

Answer: She could create 60 platters.
Step-by-step explanation:
Given: A salad bar offers vegetable platters in 4 sizes (small, medium, large, and super-sized) and 6 different vegetables to choose from.
Number of combinations of selecting <em>r</em> things from <em>n</em> things is given by:-
So, the number of combinations of selecting 2 different vegetables from 6 =
Now, By Fundamental counting principle, the number of different platters she could create = (number of ways of selecting 2 different vegetables from 6) x (Number of sizes)
= 15 x 4
= 60
Hence, she could create 60 platters.
