The statement is correct
see the explanation
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
y is the area covered by the plant in percentage
x is the time in years since 2000
r is the rate of change
a is the initial value
In this problem we have


substitute the values


In the year 2005

substitute the value of x in the exponential function

48.6% is about 50%
therefore
The statement is correct
346 pounds
u have to multiply the amount of bags (40) by the weight of each bag (8.56) so it’ll be
40 x 8.56 = 346
28
3/7 = 12/x
x = (12*7)/3
x = 84/3
x = 28
