The simplest answer, in terms of powers of 2, is 

                                             1
                                      ---------------
                                             16
                                           2
                             4                                     16
Please note that 2     equals 16, and that 2       thus equals 16^4.

Thus, another form in which the answer can be expressed is 

          1                  1
------------- , or ----------- .    If you want to take this further, calculate
        4                      2
   16                  256



           1

If you mean (x^2 -16), then x^2-16 = (x+4)*(x-4). This follows from the formula a^2 - -b^2=(a+b)*(a-b)

A cheater travels at a rate of 90 ft./s the distance d traveled by the cheetah is a function of seconds traveled t right rule fo
HACTEHA [7]
So the equation for this would be y= 90x where y would be the distance in feet covered in x seconds and x would be seconds. So to find out the distance covered in 25 seconds you would plug in 25 for x.

y= 90(25)
y= 2250

So to answer the question you would say that the cheetah would cover 2,250 feet in 25 seconds.

The cost of using a game facility is $1 for every 12 minutes. Talisa writes the function for the cost per hour as ()=. Explain T
Anna [14]

Using proportions, it is found that Talisa's error was at calculating the cost per minute of the game.

In the function:

  • The input is x, which is the number of minutes.
  • The output is f(x), which is the cost of playing the game for x minutes.

Talisa's expression is given by:

f(x) = 12x

The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:

c = \frac{1}{12}

And the correct expression for the cost is:

f(x) = \frac{x}{12}

Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.

Does this set of ordered pairs represent a function? Why or why not. Don’t need a step to step just the answer
Scrat [10]

Answer:

D. Yes,because every x-value corresponds to exactly one y-value.

Step-by-step explanation:

The given ordered pairs are;

{(-5,-5),(-1,-2),(0,-2),(3,7),(8,9)}

We do not have the same x-value corresponding to more than one y-value.

We can see from the ordered pairs that every x-value corresponds to exactly one y-value.

Therefore the graph of this relation will pass the vertical line test.
