Agroup of scientists have been sent on an expedition to test the soil in the allegheny mountains. they need to collect samples from nine sites. the route for the expedition is shown in the image. the group starts at p and works its way around to q, r, s, t, u, v, w, and x, in that order, before returning to p. what is the length of the route? a. 50 units b. 52 units c. 55 units d. 58 units e. 60 units

B.  52 units

Step-by-step explanation:

Here we have to count the length we need count the number of units passed from P.

= 7 + 12 + 8 +6 +6 +4  + 2 +3

= 52 units

Here with I have attached the figure.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
