Answer:
The area of the polygon is 
Step-by-step explanation:
Sketch the polygon to obtain the figure in the attachment.
The polygon can then be divided into a rectangle and a triangle.
The area of the polygon
We use the absolute value method to find the lengths
Arc length: s = radius (central angle)
Here, 18 cm = (radius)(7pi/8)
Solving for the radius:
18 cm (18 cm)(8)
radius = --------------- = ------------------ = ? Please calculate this.
(7pi/8) 7pi
-1/2 x 1/2 = -1x1 / 2x2 = -1/4
The answer is -1/4
Answer:
The answer is 1,000
SInce the beginning number is 3 and there are ten possible numbers to put in the remaining three slots, there are exactly 1,000 possible combinations for a 3-digit code. The answer is 1,000. There are 3 rows of 10 digits. The number of combinations 10 to the thid power which is 1000 (10 * 10 * 10)
The factorisation of the given expressions is as follows;
- a) p²y²– 2py + 1 = (py -1)²
- b) a²y² -2aby +b² = (ay - b)²
<h3>Factorization using identities</h3>
The given identity is;
From the given identity, we can conclude that;
In the expression (a);
- py represents a in the identity and 1 represents b in the identity.
In the expression (b);
- ay represents a in the identity and b represents b in the identity.
Hence, the factorised expressions are as represented above.
