Answer: (0, 0) & (3, √3)
<u>Step-by-step explanation:</u>
Since we need a distance of 2, I graphed y = √x and then drew a circle at center (2, 0) and radius of 2 to see where they intersect.
The coordinates of intersection can be determined by solving a system of equations.
Equation 1: y = √x
Equation 2: (x - 2)² + y² = 2²
I will use the Substitution method with Equation 2 to solve for x:
(x - 2)² + (√x)² = 2² substituted y with √x
x² - 4x + 4 + x = 4 expanded binomial
x² - 3x + 4 = 4 added like terms
x² - 3x = 0 subtracted 4 from both sides
x(x - 3) = 0 factored
x = 0 x - 3 = 0 applied Zero Product Property
x = 3
Next, solve for y using Equation 1:
x = 0: y = √0 = 0
x = 3: y = √3
Coordinates of intersection are: (0, 0) & (3, √3)
Answer:
Qualitative data
Step-by-step explanation:
Qualitative methods like an interviews and observations that are considered valuable as of their detail, descriptiveness, and uniqueness.
In this given situation, it is already known that the specific painter who outperforms in the factory.
And my motive is to gain an understanding with respect to the performing as a best painter for an automative industry so the same information would be observed and interviewed him
