Adrawbridge in jacksonville, fl, allows an average of 22 boats per day to pass. what does the point (4,88) on the graph mean in this situation?

This shows, 'After 4 days, 88 boats will have passed under the bridge'.

Explanation:

Since, According to the question, Jacksonville allows an average of 22 boats per day to pass.

Thus we can say that number of boats is dependent on days and both are varying.

And, a function is the type of y=f(x), where x is independent variable while y is dependent variable.

So, we can take x for representing number of days and y for representing number of boats.

Thus, according to the question,  y= 22x.

if we take 4 days i.e. x=4 then y=22×4=88

⇒It takes 4 days for an average of 88 boats.

Which is showing by (4,88) on the given graph.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
