The number of bacteria will modeled using exponential growth function, this is given by:
f(x)=a(b)^x
where
a is the initial amount
b=ratio of growth
x=time
Thus from our information we shall have:
f(x)=R(t)
a=1000
b=r
t=x
hence we shall model the situation by:
R(x)=1000(r)^t
Hence in 3 years time the population will be modeled by the function:
R(x)=1000(r)^3=1000r³

A rectangle has width w and its length is 2 units shorter that 3 times the width
topjm [15]
2(3w-2+w)
=2(4w-2)
=8w-4

the formula for solving perimeters is 2(WL). so L=3w-2, because the question said the length is 2 units shorter than 3 times the width, and the width is w. so the final equation is <span>2(3w-2+w), and then you just have to simplify that </span>
