Answer:
f(x) = 2x^2 - 3x + 1
Step-by-step explanation:
The root 1 is associated with the factor (x - 1).
The root 1/2 is associated with the factor (x - 1/2), which in turn is equivalent to (2x -1)
The quadratic in question is f(x) = (x - 1)(2x - 1). To write this in standard form, perform the indicated multiplication:
f(x) = 2x^2 - 2x - x + 1, or f(x) = 2x^2 - 3x + 1

Step-by-step explanation:c
It's simple you've been told that correct answers equals 6/7 and she did all the questions. Therefore the incorrect answers equals 1/7, which is 4. So just times 4 by 7. 4 x 7 = 28. 28 questions on the quiz.
Answer:
40 mm
Step-by-step explanation:
The rectangular prism of a rectangular box. The volume is given by the formula:
<u>Volume of Rectangular Prism</u> = length * width * height
Given Volume = 3200
Length = 10
Width = 8
We need to find height. So we plug in the given information and find the height, in mm. Shown below:
Volume = Length * Width * Height
3200 = 10 * 8 * Height
3200 = 80 * Height
Height = 3200/80
Height = 40 mm
The height (h) = 40 mm
Answer:
Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have
This is the equation of the line in slope intercept form
where
The given equation not represent a proportional relationship, because the line not pass through the origin
In a proportional relationship the value of b (y-intercept) is equal to zero
