Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = (x - h)² + k (h, k) are the coordinates of the vertex
Given y = x² + 7x - 5
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term )²
y = x² + 2(
)x +
-
- 5
y = (x +
)² -
- 
y = (x +
)² - 
Hence
a =
and b = - 
Red=2 nits
blue=4 nits
if 6liters=blue=4 units
divide 2
3 liters=2 units=red
red=3 liters
Do you have a picture or something?
No 6.52 is equal to 6.520.
The reason for this is because even if you add more ceros to the othe side of 6.52 it would not matter unless there is another number other than 0, Like 6.52000000000000001 is bigger than 6.52 ans smaller tahn 6.5200000000000000000000
It’s used to correct statistical averages that include obvious imbalances because of outliers in the data set.
