Answer:
Step-by-step explanation:
we know that
The equation of a exponential growth is equal to
where
a is the initial value
r is the rate of growth
x is the time in hours
y is the value of the quantity
we have
substitute
For x=22 hours
look at how I rounded them and put in the answer it says to round to
84 + 132 = 216
84 / 216 = 38.88%
rounded to the nearest hundredth = 38.89%
rounded to the nearest tenth = 38.9%
rounded to the nearest whole number = 39%
=2.1 ×8.4×4
=70.56
