9 dollars is 4 dollars.
Let's find the percent form of the discount
=> 4 dollars / 9 dollars = 0.44
Now, let's convert it to percentage
=> 0.44 * 100% = 44%
Thus the discount is 44%
Recall that a rational function:
![\frac{P(x)}{Q(x)},](https://tex.z-dn.net/?f=%5Cfrac%7BP%28x%29%7D%7BQ%28x%29%7D%2C)
has a vertical asymptote at x₀ if and only if:
![Q(x_0)=0.](https://tex.z-dn.net/?f=Q%28x_0%29%3D0.)
Also, the roots of the above rational function are the same as P(x).
Since the rational function has a vertical asymptote at x=-1, we get that its denominator must be:
![Q(x)=x+1\text{.}](https://tex.z-dn.net/?f=Q%28x%29%3Dx%2B1%5Ctext%7B.%7D)
Since the rational function has a double zero at x=2 we get that its numerator must be of the form:
![P(x)=k(x-2)(x-2)\text{.}](https://tex.z-dn.net/?f=P%28x%29%3Dk%28x-2%29%28x-2%29%5Ctext%7B.%7D)
Finally, since the rational function has y-intercept at (0,2) we get that:
![2=\frac{P(0)}{Q(0)}=\frac{k(0-2)(0-2)}{0+1}\text{.}](https://tex.z-dn.net/?f=2%3D%5Cfrac%7BP%280%29%7D%7BQ%280%29%7D%3D%5Cfrac%7Bk%280-2%29%280-2%29%7D%7B0%2B1%7D%5Ctext%7B.%7D)
Simplifying the above equation we get:
![\begin{gathered} \frac{k(-2)(-2)}{1}=2, \\ 4k=2. \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7Bk%28-2%29%28-2%29%7D%7B1%7D%3D2%2C%20%5C%5C%204k%3D2.%20%5Cend%7Bgathered%7D)
Dividing the above equation by 4 we get:
![\begin{gathered} \frac{4k}{4}=\frac{2}{4}, \\ k=\frac{1}{2}\text{.} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B4k%7D%7B4%7D%3D%5Cfrac%7B2%7D%7B4%7D%2C%20%5C%5C%20k%3D%5Cfrac%7B1%7D%7B2%7D%5Ctext%7B.%7D%20%5Cend%7Bgathered%7D)
Therefore, the rational function that satisfies the given conditions is:
![f(x)=\frac{\frac{1}{2}(x-2)(x-2)}{x+1}\text{.}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B%5Cfrac%7B1%7D%7B2%7D%28x-2%29%28x-2%29%7D%7Bx%2B1%7D%5Ctext%7B.%7D)
Answer:
The numerator is:
![\frac{1}{2}(x-2)(x-2)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%28x-2%29%28x-2%29)
The denominator is:
Answer:
4,500 items are made every 4 hours.
5,625 items are made every 5 hours.
Step-by-step explanation:
when you multiply 1125 by for it will equal 4500 and when you multiply 1125 by 5 it will equal 5625
The correct answer for the question that is being presented above is this one: "18.12."
The image of this triangle is an isosceles triangle<span> with the base being 33 m (from angle A to angle A') and the right leg is 7.5 m long (BC) the span or width of the triangle is divided by 6 vertical lines with equal distances from each other. so we need to find the length of the left leg AB.</span>
18 Kids in his class you have to divide 72 by 4 which will give u 18
