Answer:
f(x) = [x – (4 + √20)][x – (4 – √20]
Step-by-step explanation:
In order to know the function that best describes the given f(x) that best reveals it's minimum or maximum, we need to know solve for x.
x² – 8x – 4 = 0
Using completing the square method
x² – 8x = 4
x² – 8x + 4² = 4 + 4²
(x – 4)² = 20
x = 4 ±√20
Therefore
f(x) = [x – (4 + √20)][x – (4 – √20]

Step-by-step explanation:
1.We choose a fish pond of radius 3 centered at (x, y) = (0, 3). The equation of the circle is ...
(x -0)^2 +(y -3)^2 = 3^2
x^2 +(y -3)^2 = 9
At this location it is easy to draw a radius along the y-axis to a point of tangency at the origin. That radius is a vertical line, so the tangent line will be perpendicular--a horizontal line.
A horizontal line through the origin has equation y = 0, and its point of intersection with this circle is (0, 0).

Comment on the question
You haven't elaborated on what the lesson discussed, so we have no idea what steps you want included.
I could not answer 2 and 3 but maybe if i get it i will edit this paper and add it in.
Answer:177
Step-by-step explanation:so for short, you need to multiply the 300 miles with the 59 precent we have and divide it to 100 this provides us the answer of miles he slept through the road trip
Hi
formula. for circumference of a circle is. : 2πR. if you have the radius.
As the diameter is twice the radius, then circumference is. diameter π
then : 18*π≈ 56.52
the mistake was to take the diameter as the radius.
