           A = πr² + πrl
  306.00 = 3.14(6)² + 3.14(6)(l)
  306.00 = 3.14(36) + 3.14(6l)
  306.00 = 113.04 + 18.84l
- 113.04  - 113.04
  192.96 = 18.84l
   18.84      18.84
    10.24 ≈ l

The fish population of Lake Collins is decreasing at a rate of 5% per year. In 2000 there were about
olchik [2.2K]

Answer:

Number of fish in 2006 = 845 fishes (Approx.)

Step-by-step explanation:

Given;

Number of fish in 2000 = 1,150 fishes

Decreasing rate = 5% per year

Find:

Number of fish in 2006

Computation:

Exponential decay function:

F = P[1-r]ⁿ

Number of year = 2006 - 2000

Number of year =  6 year

Number of fish in 2006 = 1,150[1-5%]⁶

Number of fish in 2006 = 1,150[1-0.05]⁶

Number of fish in 2006 = 1,150[0.95]⁶

Number of fish in 2006 = 1,150[0.735]

Number of fish in 2006 = 845.25

Number of fish in 2006 = 845 fishes (Approx.)

Graph the six terms of a finite sequence where a1 = −6.25 and r = 1.25.
Virty [35]

Answer:

Step-by-step explanation:

As per the question statement, a₁ is -6.25 and common ratio (r) is 1.25.

Therefore, the six terms of finite sequence would be as per the following equation f(n) = a1(r)^{n-1}. Thus, the series would be

  1. a1 = -6.25
  2. a2 = -6.25*r = -6.25*(1.25) = -7.8125
  3. a3 = -6.25*r^2 = -6.25*(1.25)^2 = -9.765625
  4. a4 = -6.25*r^3 = -6.25*(1.25)^3 = -12.20703125
  5. a5 = -6.25*r^4 = -6.25*(1.25)^4 = -15.2587890625
  6. a6 = -6.25*r^5 = -6.25*(1.25)^5 = -19.073486328125

So the points on the graph will be on following points,

(1, -6.25), (2, -7.8125), (3, -9.765625), (4, -12.20703125), (5, -15.2587890625), (6, -19.073486328125).

The graph would look like as attached.

Carpet costs $21.95 per square yard and the padding to put under it costs $2.55 per square yard. Felix plans to install padding
marusya05 [52]

Answer:

$1679.175 or $1679.18

Step-by-step explanation:

split the carpet into rectangles to make it easier to look at

one rectangle is 2 yards in height and 9 yards in width (5 yards plus 4 yards)

area of a rectangle = (w)(h), so 9 x 2 = 18 yards in area.

second triangle is 4 yards in width, and 3 yards in height.

area of a rectangle = (w)(h), so 4 x 3 = 12 yards in area.

Total area = 30 yards

30(21.95)(2.55) = $1679.175 or $1679.18
