For a function g(x), the difference quotient is StartFraction 6 Superscript x + h minus 3 Baseline minus 6 Superscript x + 3 Bas
kobusy [5.1K]

Answer:

The average rate of change in that interval is 1.99

Step-by-step explanation:

Here we have that the difference quotient for g(x) is:

\frac{6^{x + h} - 3 - 6^x + 3}{h}

Remember that for a general function f(x), the difference quotient is:

\frac{f(x + h) - f(x)}{h}

So if we look at the difference quotient for g(x), we can conclude that:

g(x) = 6^x - 3

Also remember that the average rate of change in an interval (a, b) is just:

\frac{g(b) - g(a)}{b - a}

So here we want the average rate of change of g(x) in the interval from x = -2 to x = 1, this is:

R = \frac{(6^1 - 3) - (6^{-2} - 3)}{1 - (-2)}  = \frac{6 - 6^{-2}}{3} = 1.99

The average rate of change in that interval is 1.99

The total width of two standard shortboards
sergey [27]

Answer:

2s + t = 23.5

Step-by-step explanation:

There are two types of shortboards:

  • standard
  • technical

Let the width of a standard shortboard be represented by s.

Similarly, Let the width of a technical shortboard be represented by t.

As per the given information: total width of two standard shortboards

and a technical shortboard is 23.5 inches.

Representing it as an equation in terms of the variables defined:

2s + t = 23.5
