Answer:

  26.  106

  27.  -7.9% per year

  28.  shrinking

  29.  31

  30.  $9560.92

  31.  $8243.61

Step-by-step explanation:

26. The value when t=0 is 106·.921^0 = 106·1 = 106

__

27. The rate of change is 0.921 -1 = -0.079 = -7.9% per year. It is a good idea to put the sign with the rate of change, so you know whether it is increasing or decreasing. Also, units are a good idea: "per year."

__

28. The negative rate of change means the population is shrinking.

__

29. In 15 years ...

   y = 106·0.921^15 ≈ 30.8 ≈ 31

In 15 years the deer population is predicted to be 31 deer.

__

30. $5000(1 +.065/12)^(12·10) ≈ $9560.92 . . . . units are a good idea (dollars)

__

31. $5000·e^(.05·10) ≈ $8243.61 . . . . the exponential term has a time multiplier

_____

Numbers are correct. IMO, some details need attention.

Can someone please answer this really quick question?

|2x-3|=2x-1

need to consider two cases

(1) 2x-3<0 --> x<3/2

-(2x-3)=2x-1

x=1, and this is <3/2 so that's a valid solution

(2) 2x-3>=0 --> x>=3/2

2x-3=2x-1

-3 = -1 so there no solution for x>=3/2


The single solution is x=-1

Solution #2:

x - 1/2 = 4

x + (-1/2) = 4

x + (-1/2) + 1/2 = 4 + 1/2

x = 4 1/2 ✔

--------------------------------

Solution #3:

x - 1.2 = 4

x + (-1.2) = 4

x + (-1.2) + 1.2 = 4 + 1.2
