Answer:
(d) D: [0, 60]; R: [-15, 0]
Step-by-step explanation:
The model is of the underwater portion of the net, so the only part of the graph we're interested in is that below the x-axis.
The x-intercepts of 0 and 60 define the bounds of the domain.
The range is the vertical extent of the graph in that domain, from y=-15 to y=0.
So, the domain and range are ...
Domain: 0 ≤ x ≤ 60
Range: -15 ≤ y ≤ 0

Answer:
The solutions are:
and 
Explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
2x² - 6x + 5 = 0
By comparison:
a = 2
b = -6
c = 5
Now, to get the solutions of the equation, we will have to use the quadratic formula shown in the attached image.
By substituting in the formula, we would find that:
either x =
or x =

We need to construct the system of equations in order to solve that problem. Let's denote one-time membership fee with x and monthly fee with y. Then we can write that John paid x+6y=325 and Abigail paid x+9y=475. Solving the system of equations 
, we find that x=25 and y=50. The monthly fee is 50 dollars.
