Answer:
When we add 9 to the function we are shifting the function up 9 units.
Step-by-step explanation:
If it were added inside the function, it woulds shift it left or right.
But since it is outside the function, we will shift it up or down
When we add 9 to the function we are shifting the function up 9 units.
For this case, the first thing we want to do is substitute the value of y = 15 in the equation.
We have then:
15 = -0.08x ^ 2 + 1.6x + 10
Rewriting we have:
0 = -0.08x ^ 2 + 1.6x + 10 - 15
0 = -0.08x ^ 2 + 1.6x - 5
The solutions are:
x1 = 3.876275643042054
x2 = 16.123724356957947
Nearest whole number:
x1 = 4
x2 = 16
were about 15 tons of trout caught in the lake in the years:
1995 + 4 = 1999
1995 + 16 = 2011
Answer:
The year 1999 and the year 2011
Answer:
4x² -29x +51
Step-by-step explanation:
Put x-3 where x is in the original function definition, then "simplify". I think you'll find it convenient to rewrite the original function definition first.
... g(x) = 4x² -5x = x(4x -5)
Substituting, we have
... g(x-3) = (x -3)(4(x -3) -5)
... = (x -3)(4x -17) . . . . . simplify right factor
... = 4x² -12x -17x +51
... g(x -3) = 4x² -29x +51
Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements,
, is given by:
![G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}](https://tex.z-dn.net/?f=G%20%3D%20%5Csqrt%5Bn%5D%7Bn_1%20%5Ctimes%20n_2%20%5Ctimes%20...%20%5Ctimes%20n_n%7D)
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
- Two elements(n = 2), a and 34.
![G = 6\sqrt{17}](https://tex.z-dn.net/?f=G%20%3D%206%5Csqrt%7B17%7D)
Thus:
![\sqrt{34a} = 6\sqrt{17}](https://tex.z-dn.net/?f=%5Csqrt%7B34a%7D%20%3D%206%5Csqrt%7B17%7D)
We find the square of each side, so:
![(\sqrt{34a})^2 = (6\sqrt{17})^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B34a%7D%29%5E2%20%3D%20%286%5Csqrt%7B17%7D%29%5E2)
![34a = 36\times17](https://tex.z-dn.net/?f=34a%20%3D%2036%5Ctimes17)
Simplifying both sides by 17:
![2a = 36](https://tex.z-dn.net/?f=2a%20%3D%2036)
![a = \frac{36}{2}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B36%7D%7B2%7D)
![a = 18](https://tex.z-dn.net/?f=a%20%3D%2018)
The value of a is 18.
