If Sue rides 10 miles per hour on her bike, and this relationship is graphed, which ordered pair would not be on the graph?

-Dominant- [34]

Answer:

(8, 85) Would make this relationship not a function because every time you count up 1 it goes up 10 and 8 would match to 80 not 85 making 8, 85 the ordered pair would not be on the graph.

The ordered pairs (2, 20) and (3, 40) are solutions to an exponential function. Write the equation for this function.

weeeeeb [17]

Answer:

The exponential function will be $f(x) = 5(2)^{x}$

Step-by-step explanation:

Let the exponential function is given by $f(x) = a(b)^{x}$ ............ (1)

Now, ordered pairs (2,20) and (3,40) are the solution of the above exponential function. So, they will satisfy the equation.

Now, for the ordered pair (2,20) putting f(2) = 20, we get

$20 = a(b)^{2}$ ............. (2)

Again, for the ordered pair (3,40) putting f(3) = 40, we get

$40 = a(b)^{3}$ ............. (3)

Now, from equations (3) and equation (2) we get,

2 = b

⇒ b = 2.

Now, from equation (2) we get, $20 = a(2)^{2} = 4a$

⇒ a = 5

Therefore, the exponential function will be

$f(x) = 5(2)^{x}$ (Answer)

I think maybe 3) would make the most sense because she wants a random sample of students and the other options are specific on the type of students.
