Answer:
Step-by-step explanation:
Given that demand function for a product is modeled by
where p = price in dollars and
x= units demanded
a) When x=1000, we substitute 1000 for x
i.e. price is 1092.32 dollars
b) X = 1500
i.e. price is 692.28 dollars
c) When x increases without bound exponent with negative power becomes 0 making price = 10000(1-3/3) =0
Let's write the parametric line
(x,y,z) = (0,2,8) + t(5,-1,4)
(5,-1,4) is called the direction vector of the line. It's normal to the plane
5x - y + 4z = constant
We get the constant by substituting the point (3,0,7),
5x - y +4z = 5(3) - 0 + 4(7) = 43
5x - y +4z = 43
1,000/5 so its 1000 Divided by 5
1,000/2 so its 1000 Divided by 5
138 miles just divide miles for 4 gal. by 4 then multiply that number by 6
Answer:
y=-2/5x^2-3x+63
Step-by-step explanation:
Use y=mx+b
