Answer:

Labeled the diagram as shown below.,

In rectangle ABCD:

Area of the rectangle(A) is given by:

From the diagram:

AB = DC = 8 in. and AD = BC = 7 in.

⇒Length = 7 in. and width = 8 in.

then;

Next, find the area of triangle OAE:

In triangle OAE

Base = AE = 3 in.

Height = OA = 4 in.

then;

Area of this composite figure = area of rectangle ABCD+ area of triangle OAE

⇒Area of this composite figure = 56 +6 = 62 square inches.

therefore,  area of this composite shape is, 62 in²

Use the parabola tool to graph the quadratic function f(x)=2x^2−8x+2.
garik1379 [7]

Answer:

(0, 2) and (2, -6), among other points!

Step-by-step explanation:

If all you need is two points, choose two values for x and plug them into the formula for the function.

x=0 \Rightarrow 2(0)^2-8(0)+2=2  so the point (0, 2) is on the graph.

x=2 \Rightarrow 2(2)^2-8(2)+2=-6  so the point (2, -6) is on the graph.

Likurg_2 [28]

Answer: 152.46 squared centimeters.

Step-by-step explanation:

  1. The equation to find the area of the trapezoid is A = ½ (6.6 + 16.5) 13.2
  2. Distribute ½ into (6.6 + 16.5) . A = (3.3 +  8.25) 13.2.
  3. Add the numbers inside the parenthesis. A =  11.55 * 13.2
  4. Multiply 11.55 * 13.2.   A = 152.46.
