A kite was broken into two triangles of the same size and shape. The area of each triangle is square centimeters. The total area of the kite is square centimeters.

Each triangle:40 cm²

Kite : 80cm²

Step-by-step explanation:

The area of a triangle is

1/2bh

The height of the triangle is

h=1/2(10)=5cm

and the base is 16 cm.

The area of each triangle is

= 1/2(16)(5)=40cm^2

2. The total area of the kite is 2 times the area of one triangle.

= 2*40=80cm^2

The area of each triangle is  

✔ 40

square centimeters.

The total area of the kite is  

✔ 80

square centimeters.

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
