Answer:
The vertex represent the minimum amount of profit
Step-by-step explanation:
Plot the function to better understand the problem
Let
x ----> the number of users in thousands
y ---> the Monthly profit in thousands
using a graphing tool
see the attached figure
we have a vertical parabola open upward
The vertex represent a minimum
In the context of this problem
The vertex represent the minimum amount of profit
In this problem the vertex is the point (0.4,-4)
0.4 represent -----> 0.4(1,000)=400 users
-4=-4(1,000)=-$4,000 (profit negative)
Answer:
A drawing that shows a real object with accurate sizes reduced
Step-by-step explanation:
Given that the value of the car is given by the function:
y=15000(1/5)^x
the graph will be represented as follows:
From the graph we see that the domain is all real numbers.
Answer:
A. 1/3
Step-by-step explanation:
6/18 = 0.3333333333333333333
so in fraction it is 1/3
M + (-9.5) = -7.8
First, simplify your brackets. / Your problem should look like:
Second, change addition to subtraction. / Your problem should look like:
Third, add 9.5 to both sides. / Your problem should look like:
Fourth, simplify. / Your problem should look like:
