Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 1)

Point (2, 2)

Step 2: Identify

x₁ = 0, y₁ = 1

x₂ = 2, y₂ = 2

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points/variables [Slope Formula]: $\displaystyle m=\frac{2-1}{2-0}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{1}{2}$

The city is planning to add a fishpond to a neighborhood park the figure below is a scale drawing of the fishpond it's scale is

notsponge [240]

I saw the figure of the fishpond. It composed of a rectangle and a circle. The circle is cut into two and each half is attached to the width of the rectangle making an oblong shaped fishpond.

Length of the rectangle: 2.5 inch
Width of the rectangle and diameter of the circle: 1 inch

1/2 inch equals 15 feet.

2.5 inches = 75 feet
1 inch = 30 feet

Area of a rectangle = 75 ft * 30 ft = 2,250 ft²
Area of a circle = 3.14 * (15ft)² = 3.14 * 225ft² = 706.50 ft²

Total Area = 2,250 ft² + 706.50 ft² = 2,956.50 ft²

The polynomial 24x3 − 54x2 + 44x − 99 is factored by grouping. 24x3 − 54x2 + 44x − 99 24x3 + 44x − 54x2 − 99 4x(____) − 9(____)

Sati [7]

24x³ - 54x² + 44x - 99 =
(24x³ + 44x) - (54x² + 99) = 
4x(6x²+11) - 9 (6x² + 11) =
(4x-9)(6x²+11)

Answer: (6x²+11)
