Randy makes $200 per week. His employer deducts 4% of his earnings for Randy's medical insurance. How much of his weekly salary does Randy pay for medical insurance?

$8 Randy pay for medical insurance.

Step-by-step explanation:

Given:

Randy makes $200 per week.

His employer deducts 4% of his earnings for medical insurance.

Now, to find the salary Randy pay for medical insurance.

Salary Randy makes per week = $200.

Rate of deduction of medical insurance = 4%.

So, to get the amount of salary Randy pay for medical insurance:

Therefore, $8 Randy pay for medical insurance.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
