The answer should be f(x)=20(2.5)^x

How?

the graph crosses the f(x) axis at 20 but that's common in all 4 equations. However, when x=1, f(x)=50. We have to know try all the equations by substituting these values in ( both sides are equal).

f(x)=20(2.5)^x
substitute f(x)=50, x=1
50=20(2.5)^1
50=20*2.5
50=50

2. when x = -2 it is 10 am because when x is 0, it is noon, or 12 pm, her elevation is 7 meters above sea level

17/9 15 divided 6 divided 30 divided and 3^3 from least to greatest
qaws [65]

I assume you mean: Order the following from least to greatest:

17/9, 15 divided by 6, 30, and 3^3

17/9 = 1 8/9

15/6 = 2 1/2

3^3 = 9

So it would be: 17/9, 15 divided by 6, 3^3, and 30

Make necessary adjustments if it was actually 6/30; the wording was confusing.
