Which of the following options results in a graph that shows exponential growth? (2 points) f(x) = 0.4(3)x
f(x) = 3(0.5)x
f(x) = 0.8(0.9)x
f(x) = 0.9(5)−x

Step-by-step explanation:

The formula for exponential equations is

where a is the initial value and b is the growth rate. If b is greater than 1, we have growth; if  0 < b < 1, then we have decay. The only choice that shows a b value greater than 1 is the first one where b = 3. (The last one is also a decay as it can be written as

which isn't even exponential!)

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant
