1. The demand function for a particular product is q = f(p) = 200,000e-0.15p
where q equals demand (in units) and p equals price (in dollars).
a) What is demand expected to equal at a price of $20.
b) Construct the total revenue function R= = f(p).
c) What is the total revenue expected to equal at a price of $25? What is
the demand at this price?

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

where is the picture

step-by-step explanation:

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
