Which equation represents an exponential function that passes through the point (2, 80)?
s2008m [1.1K]

Answer:

D) f(x) = 5(4)ˣ

Explanation:

(x, y) = (2, 80)

Check by inserting x = 2

A) y = 4(x)⁵ = 4(2)⁵ = 128

B) y = 5(x)⁴ = 5(2)⁴ = 80  - passes

C) y = 4(5)ˣ = 4(5)² = 100

D) y = 5(4)ˣ = 5(4)² = 80 - passes

An exponential equation is in a(b)ˣ format, so only f(x) = 5(4)ˣ is an exponential equation which passes the point (2, 80)

Solve problem number 10 please
Dima020 [189]

You can spend about 3.54 per square ft.

In order to find this we will need to figure out how many square ft. there are exactly. We can do this by doing 20 x 12, which is 240. Now, to figure how much we could spend per square ft., we would have to do 850 / 240, which is(rounded) 3.54.
