Open Question: Potential zeros of polynomials?
Determine the maximum numbers of real zeros each polynomial can have. Then list the potential zeros.
Open Question: Visual angle and image size on the retina?
Please tell me the formulas to figure out the answers for each of the problems so that I know how to do them:
Suppose that the focal length of the eye (the distance from the lens to the retina) is 2 cm. Your blind spot subtends an angle of roughly 5 deg. How big is the blind spot (in cm) on your retina? (Use the focal length as the distance in the visual angle equation).
The fovea is roughly 2 deg of visual angle. What is the diameter of the fovea in cm? (Use 2 cm again as the focal length).
Open Question: use given zero to find the remaining zeros of the polynomial?
use given zero to find the remaining zeros of the polynomial?
g(x) = x^3 + 3x^2 + 25x + 75 Zero: -5i
if one zero is (- 5i), then (5i) is also a zero
(x + 5i)(x - 5i) = x^2 + 25
long division by (x^2 + 25) yields the quotient: (x + 3)
the remaining zero is: x = - 3

Open Question: What coordinates satisfy this slope?
Technically, your question doesn't make any sense, since a coordinate cannot have a slope, only a line can.
The formula 'y=mx+b' describes a straight line, where 'm' is the slope, and 'b' is the y-intercept.
Any two lines with the same slope will be parallel to each other, so any line whose 'y=mx+b' formula has the same 'm' value and a different 'b' value will satisfy the requirements of your questions.
So, for instance:
y = 10x + 1 and y = 10x + 2 are the formulas for two parallel lines with a slope of 10.
To get coordinates on these lines, just plug in values for 'x' and solve for 'y'. For instance:
(0,1), (1,11), and (2,21) are on the line 'y = 10x + 1', and
(0,2), (1,12), and (2,22) are on the line 'y = 10x + 2'.
