Answer:
2300 mm^2
Step-by-step explanation:
You can turn 0.05 to a fraction by
1- Look at how many digits are beyond the decimal
2- Then put the number 5 as a numerator and your denominator will be 100 because the number 5 is on the hundredths place so 0.05 as a fraction will be 5/100
Given:
The three points are (-7,134), (-3,10) and (5,50).
To find:
The equation of parabola using quadratic regression.
Solution:
The general equation of quadratic regression is
...(i)
The three points are (-7,134), (-3,10) and (5,50).
Using the graphing calculator, we get a=3, b=-1 and c=-20. Putting these values in (i), we get
![y=3x^2+(-1)x+(-2)](https://tex.z-dn.net/?f=y%3D3x%5E2%2B%28-1%29x%2B%28-2%29)
![y=3x^2-x-2](https://tex.z-dn.net/?f=y%3D3x%5E2-x-2)
Therefore, the equation of parabola is
and the missing values in the given equation are 3, -1 and -20.
<span>First you take 3/4 of the tank (18000 gallons)
then you have to divide that by 40 to find out how many minutes it will take to get it.
the answer would be 450 minutes</span><span>i hope that thiss helps you out, have an amazing day!!</span>
