Answer:
when input = n, Output = 4n
Step-by-step explanation:
Output = k(input)
Where,
k = constant
Find k When output = 8 and input = 2
Output = k(input)
8 = k(2)
8 = 2k
k = 8/2
k = 4
Find k When output = 28 and input = 7
Output = k(input)
28 = k(7)
28 = 7k
k =28/7
k = 4
Find output when input = n
Output = k(input)
= 4(n)
= 4n
Output = 4n
when input = n, Output = 4n
Step-by-step explanation:
I didn't know this off of the top of my head, and I used Google to help me. Simply searching "30 60 90 right triangle" gave me a few very helpful links. For future reference, if no one is answering here, Google may be your friend.
The (credible) site that I found tells me
"The basic 30-60-90 triangle ratio is:
Side opposite the 30° angle: x
Side opposite the 60° angle: x * √3
Side opposite the 90° angle: 2x"
The side opposite the 30 degree angle is a value called "x" according to this site. This would mean that y is x, which is confusing, so we can just say that the value of y is y (if you want to go a little more in depth, I will simply be referring to what the site refers to as "x" as "y"). To begin, the side opposite the 30 degree angle, which is 8√3, is y * √3. This means that y is 8. Then, the remaining side is 2*y, which is 16.
Please let me know if you have any further questions or concerns.

Answer:
- $10,000 at 5%
- $22,000 at 6%
Step-by-step explanation:
Let x represent the amount invested at 6%. Then 32000-x is the amount invested at 5%, and the total interest earned is ...
0.06x +0.05(32000 -x) = 1820
0.01x +1600 = 1820 . . . . simplify
0.01x = 220 . . . . . . . . . . subtract 1600
x = 22,000 . . . . . . . . . . . multiply by 100
32000 -x = 10,000
Phyllis invested $22,000 at 6% and $10,000 at 5%.
