The function f(x)=50⋅0.8x models the number of ants in Jonathan's ant farm after it is stricken by a deadly ant disease, where x
alina1380 [7]

Answer:

Step-by-step explanation:

In the exponential growth/decay function

y=a(b)^x, in our situation,

y is the number of ants remaining in the colony after the growth or decay,

a is the initial number of ants in the colony, and

b is the growth/decay rate.  Rule:  if b is greater than 1, the function is growth; if b is greater than 0 but less than 1, the function is decay.

Our equation looks like this (it's given):

y=50(.8)^x

a = 50, which is the initial number of ants in the colony.

b = .8 (which actually means that then number of ants is declining by 20% each week).  Since .8 is a fraction of 1, this is decay.

So far, we know that 1 and 4 are true.  Let's look at 5.  We have to do some solving to find out if it's true or not.  If the number of ants after x = 2 weeks is 32, then we plug in 2 for x and see if the y we get as the answer is 32:

y=50(.8)^2  and

y = 50(.64) so

y = 32

5 is true as well.  Let's test 6 by replacing x with 8 and seeing if y = 10:

y=50(.8)^8 and

y = 50(.16777216) so

y = 8.388

6 is not true.

1, 4, 5 are true
