Answer:

The interval of decrease is 0 ≤ x ≤ 1.25

Step-by-step explanation:

First, we have to find the point where it changes from increasing to decreasing or decreasing to increasing.

The graph shows that there is a decrease before 1.25 h, and it increases after 1.25 h also.

We can further prove that 1.25 is the point of change when we enter 1.25 in place of t in the given equation

d(1.25) = 40|1.25 - 1.25| = 0

We see that the graph is decreasing before 1.25, so the interval will have to end at 1.25.

We also see that there is no increase before 1.25, so we can make the interval begin at 0

Jeremy’s pay started at a $500 per week. Every year his pay will increase by $25 per week. Write an equation that models his wee
algol [13]

Answer:

W = 500 + 25x

Step-by-step explanation:

Jeremy’s pay started at $500 per week. Every year his pay will increase by $25 per week.

Now, after x years his pay per week will increase by $(25x).

Therefore, if we model the weekly payment of Jeremy by an equation, then it will be given by

W = 500 + 25x

where W is his weekly payment after x years. (Answer)

Which graph represents the function of f(x) = 9x 2 -36/3x+6 Please help
UkoKoshka [18]
The function is:

             (9x^2 - 36)
f(x) = ---------------------
                3x + 6

You can simplify that function to a linear function for all x for which 3x + 6 ≠ 0

=> x ≠ - 2.

So, for x ≠ - 2, you can do:


             (9x^2 - 36)
f(x) = --------------------- =
               3x + 6

              9(x^2 - 4)
f(x) = ---------------------
                3(x + 2)

             3(x + 2)(x - 2)
f(x) = --------------------- = 3(x - 2) = 3x - 6
                 (x + 2)

So, the graph is a right line that intercepts the y-axis at - 6 and the x-axis at x = 2, excluding x = -2 as the function is not defined for x = -2. That is the second graph of the second picture.
