Answer:
Axis of symmetry is
C) x = 1
Step-by-step explanation:
we are given equation as
![2x^2 -4x+5](https://tex.z-dn.net/?f=2x%5E2%20-4x%2B5)
we can use axis of symmetry formula
Let's assume we are given quadratic equation as
![y=ax^2+bx+c](https://tex.z-dn.net/?f=y%3Dax%5E2%2Bbx%2Bc)
Axis of symmetry is
![x=-\frac{b}{2a}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7Bb%7D%7B2a%7D)
now, we can compare both equations
and we get
![a=2,b=-4](https://tex.z-dn.net/?f=a%3D2%2Cb%3D-4)
now, we can find axis of symmetry
![x=-\frac{(-4)}{2\times 2}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B%28-4%29%7D%7B2%5Ctimes%202%7D)
![x=-\frac{(-4)}{4}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B%28-4%29%7D%7B4%7D)
![x=1](https://tex.z-dn.net/?f=x%3D1)
Answer:
Hi there! I believe your answer will be D, 156°.
Step-by-step explanation:
This is because a triangle must equal 180° and you already have the degrees of two of the sides. To get the other side you need to add up the two sides, 88°, 68°, and subtract that number from 180, hencefore, receiving the number 156°.
I hope your inquiry is solved and you will better understand it for future questions.
I hope you have a great rest of your day!
It means that for every 1 unit the line goes down, the line goes 1 unit to the right
Answer:
See the procedure
Step-by-step explanation:
we know that
To find the population density per m² of each of the above species, divide the amount of each species by the total area
so
<em>Ferns</em>
![\frac{30}{15}=2\frac{ferns}{m^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B15%7D%3D2%5Cfrac%7Bferns%7D%7Bm%5E%7B2%7D%7D)
<em>Grass plants</em>
![\frac{150}{15}=10\frac{grass\ plants}{m^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B150%7D%7B15%7D%3D10%5Cfrac%7Bgrass%5C%20plants%7D%7Bm%5E%7B2%7D%7D)
<em>Oaks Trees</em>
![\frac{6}{15}=0.4\frac{oaks\ trees}{m^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B15%7D%3D0.4%5Cfrac%7Boaks%5C%20trees%7D%7Bm%5E%7B2%7D%7D)
