Answer:
x<±1 and x< -3
Step-by-step explanation:
Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality
x^2-1/3x+9<0
x^2-1/3x+9 (3x+9)²<0* (3x+9)²
(x^2-1)(3x+9) < 0
x²-1 < 0 and 3x + 9 <0
x²-1 < 0
x²<1
x<±√1
x<±1
Also 3x + 9 <0
3x < -9
x < -9/3
x < -3
Hence the required values of x are x<±1 and x< -3
Answer:
10 rounds.
Step-by-step explanation:
Let x represent number of rounds around the field.
We have been given that the distance around our playing field is 300 meters long. So distance covered in x rounds would be
meters.
We are also told that your coach wants you to run 3 kilometers. Let us convert 3 km in meters.
1 km = 1000 m
3 km = 3*1000 m = 3000 m
Now, we will equate total distance covered in x rounds by 3000 as:
![300x=3000](https://tex.z-dn.net/?f=300x%3D3000)
![\frac{300x}{300}=\frac{3000}{300}](https://tex.z-dn.net/?f=%5Cfrac%7B300x%7D%7B300%7D%3D%5Cfrac%7B3000%7D%7B300%7D)
![x=10](https://tex.z-dn.net/?f=x%3D10)
Therefore, you need to run 10 times around the field.
