Answer:
x
32
Step-by-step explanation:
"A number at least 32"
Let's use x as the number
x32
Reason: at least means greater than or equal to
The equation of the exponential model is f(x) = 3 * 0.2^x
<h3>How to determine the exponential model?</h3>
The table of data is given as:
x(-2,-1,0,1,2)
f(x)(71,13,3,0.6,0.1)
An exponential model is represented as:
f(x) = ab^x
When x= 0 and f(x) = 3;
We have:
ab^0 = 3
This gives
a = 3
When x= 1 and f(x) = 0.6
We have:
ab^1 = 0.6
This gives
ab = 0.6
Substitute 3 for a
3b = 0.6
Divide both sides by 3
b = 0.2
Substitute b = 0.2 and a =3 in f(x) = ab^x
f(x) = 3 * 0.2^x
Hence, the equation of the exponential model is f(x) = 3 * 0.2^x

Answer:
x=6
Step-by-step explanation:
-6(6+5x)-4=-220
-36-30x-4=-220
-40-30x=-220
30x=-40-(-220)
30x=-40+220
30x=180
x=180/30
x=6
