Answer:
in regards to ratios, think of fractions. If we have a ratio of 3:5, that means that in fraction form we can think of it as
3
---
5
If put this into a calculator (3 divided by 5), you will get a decimal of 0.6 as the answer. This means that any two numbers that divide and come to the same answer are equivalent to 3/5.
Now, from what it appears you are asking, they want you to find two other numbers that come to the same ratio / answer of 0.6, and that these numbers should be double. To do this, simply multiply the numerator and denominator by 2, which is double.
3 x 2 = 6
5 x 2 = 10
So our fraction now is
6
---
10
If you put that into a calculator (6 divided by 10), it will come to the same answer of 0.6. Therefore, this fraction / ratio is equivalent to the original.
If your answer is expected to be in ratio format, then it should be 6:10

Answer:
The domain is all real numbers. The range is {y|y ≤ 16}.
Step-by-step explanation:
The vertex of a parabola is given by
.
As a = -1, b = -2, c= 15 here, then the vertex is at (1,16).
As a is negative, it opens downward, so the range is {y|y ≤ 16}.
Meanwhile, all parabolic functions have a domain of 
.
