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.

Digiron [165]

Answer:

36 points each day.

Step-by-step explanation:

We have been given that we must accumulate 790 points to achieve our goal this month.

To find the number of points earned each day, on average, we will divide total number of points achieved in a month by number of business days we worked.

$\text{ Points earned each day on average}=\frac{790}{22}$

$\text{ Points earned each day on average}=35.9090909\approx 35.91$

If we need an integer answer, we can round 35.91 to 36. Therefore, we must earn 36 points each day, on average to meet our goal.

What is the lengh of the line segmant between (-3,8) and (7,8)

Sergio039 [100]

Answer:

Length = 10

Step-by-step explanation:

Normally you would use

d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

But the 2 y values are the same so y2 - y1 = 0.

d then becomes sqrt(x2 - x1)^2

d = (x2 - x1) because the square root of (x2 - x1)^2 is just (x2 - x1)

x2 = 7

x1 = -3

d = (7 - - 3) = 10
