A population of bears decreases exponentially.
timurjin [86]

Answer:

  0.8

Step-by-step explanation:

The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...

  factor = (year 1 population)/(year 0 population) = 320/400

  factor = 0.8

a line passes through the point -2 and five and has a slope of 2/3 points A(x,3) and B(-2,y)lie on the line
olasank [31]
A and B lie on the line, yes, but what specifically are you supposed to do?  Looks like your problem statement was cut off before you'd finished typing it in.

You say your line passes thru (-2,5) and has a slope of 2/3?  Then, using the point-slope formula,

y-5 = (2/3)(x+2)  This is the general equation for your line.

Now let's play around with B(-2,y).  Suppose we subst. the x-coordinate of B, which is -2, into the equation   y-5 = (2/3)(x+2); we get y-5 = (2/3)(-2+2) = 0.  This tells us that y must be 5.  But we already knew that!!

So, please review the original problems with its instructions and this discussion and tell me what you need to know from this point on.

What is the quotient of 99 divided by 9081
Artist 52 [7]

Hello from MrBillDoesMath!

Answer:

11/ 1009   (.0109 approximately)

Discussion:

99/9081 =                               => as 9081 = 9 * 1009 = 3 * 3 * 1009

99/ ( 3 * 3 * 1009)  =

(99/(3*3)) * (1/1009) =

(99/9)  * (1/1009)  =

11/ 1009 =

.0109 approximately
