Answer:

  A. the y-intercept of the graph is 900, and as X increases, f(x) approaches 100.

Step-by-step explanation:

The table can be described by the function ...

  f(x) = 100 +800·2^-x

This is an exponential decay (not a constant-rate decay) from a y-intercept of 900 down to a minimum value of 100 (not zero).

The best description is that of choice A.

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which t
katrin [286]

Answer:

7 < (third side length) < 37

Step-by-step explanation:

Add these two side lengths together.  We get 37.  Unless the 3rd side is LESS than 37, we cannot form a triangle.  

Next, subtract 15 from 22, obtaining 7.  The 3rd side has to be GREATER than 7 in order for the sides 7+, 15 and 22 to form a triangle.

7 < (third side length) < 37
