Answer:

Eli has to run for 2.25 minutes at this pace to win the bet.

Step-by-step explanation:

At his last track meet, Eli ran the 400-meter dash in 54 seconds.

So, the speed of Eli's run is $\frac{400}{54} \times 60 = 444.44$ meters per minute.

Now, if Eli is determined to run a whole kilometer with the same speed, then it will take Eli to run 1 kilometer within $\frac{1000}{444.44} = 2.25$ minutes.

Hence, Eli has to run for 2.25 minutes at this pace to win the bet. (Answer)

How can you use a point on the graph of f –1(x) = 9x to determine a point on the graph of f(x) = log9x?

Anastasy [175]

Whenever you can invert a function, you have that the graphs of $f(x)$ and its inverse $f^{-1}(x)$ are reflected with respect to the line $y=x$

So, given any point on the graph of $f^{-1}(x)$ , you can simply swap its coordinates to get the correspondent point on the original function $f(x)$

As an example, all exponential functions pass through the point $(0,1)$ , while all the logarithmic functions pass through the point $(1,0)$

Which description does NOT guarantee that a trapezoid is isosceles?

babunello [35]

A trapezoid is isosceles if and only if

(1) The base angles are congruent

(2) The diagonals are congruent

(3) The opposite angles are supplementary

So the description does not guarantee that a trapezoid is isoceles for "Congruent bases".
