9. Determine the end behavior of the given polynomial function: f(x) = -x-2x³ +3x+9.

Answers

Answer 1

Answer:

The graph increases as it approaches -∞.

The graph decreases as it approaches ∞.

Step-by-step explanation:

f(x) = -x - 2x³ + 3x + 9

f(x) = -2x³ + 3x - x+ 9

f(x) = -2x³ + 2x+ 9

Look at the highest exponent(which is 3).

SInce the highest exponent is odd, that means that the graph approaches infinity in a different direction as per negative infinity. Since the highest exponent has a negative sign:

The graph is going UP as x-values get SMALLER ( To  -∞)

The graph is going DOWN as x-values get LARGER ( To  ∞)

Hence:

The graph increases as it approaches -∞.

The graph decreases as it approaches ∞.

Answer 2

Answer:

Since the degree is odd, the ends of the function will point in the opposite directions.

Odd

Pisces is replacing paving stones for her inground pool. Her pool is 10m by 5m and is surrounded by a 1 1/2 border of paving stone. If each paving stone was 25 cm by 40 cm, in theory, how many paving stones will she need?

Answers

Answer:

The number of paving stones she needs is 540 paving stone

Step-by-step explanation:

The given dimensions of Pisces' inground pool = 10 m by 5 m

The thickness of the border surrounding the pool = 1 1/2

The dimensions of each paving stone = 25 cm by 40 cm = 0.25 m by 0.4 m

The length dimension of the pool and border = 10 + 2 × 1 1/2 = 13 m

The width dimension of the pool = 5 + 2 × 1 1/2 = 8 m

The total area of the paving stone, [tex]T_A[/tex] = Area of pool + border - Area of pool

∴ [tex]T_A[/tex] = 13 m × 8 m - 10 m × 5 m = 54 m²

The total area of the paving stone = 54 m²

The area of each paving stone, [tex]A_{EP}[/tex] = 0.25 m × 0.4 m = 0.1 m²/paving stone

The number of paving stones she needs, n = (The total area of the paving stone)/(The area of each paving stone)

∴ n = 54 m²/(0.1 m²/paving stone) = 540 paving stone.

For each triangle find the value of x

Answers

Answer:

x = 20

Step-by-step explanation:

The sum of the angles in a triangle is 180. A right triangle has one angle of 90. Thus, the sum of the other two angles will be 90. So, 90+31 = 121 and 180-121 = 59. (3x-1) = 59. Solve for x. This would mean that x would be 20. 3*20 = 60 and 60-1 = 59. All the angles add together would get 180: 59+90+31.
