Answer: 8.632
<u>Step-by-step explanation:</u>
First, you need to find the length of AE. Since ΔAEC is a right triangle, we can use:
Next, Use Heron's formula to find the Area of ΔADE.
Heron's formula is:

Answer:
x=4
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
(6+x) * 6 =(5+x+3) *5
(6+x) * 6 =(x+8) *5
Distribute
36+6x = 5x+40
Subtract 5x from each side
36+6x-5x = 5x-5x+40
36+x = 40
Subtract 36 from each side
36+x-36 = 40-36
x = 4
Answer:
12.
Step-by-step explanation:
Average rate of change = (value of the function when x = 9 - value when x=3)
/
(9 - 3)
= f(9) - f(3) / (9-3)
= (9^2 - 3^2) / (9-3)
= 72 / 6
= 12.
Area of the sector is 4.71 sq units
Step-by-step explanation:
- Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.
Area of the sector = πr²(C/360) = 9π × 60/360
= 9 × 3.14 × 1/6
= 28.26/6 = 4.71 sq units
