Area of the sector is 981.3 cm²
Step-by-step explanation:
- Step 1: Find the area of the sector where radius = 50 cm and central angle = 45°
Area of the sector = πr² (C/360), where r is radius and C is the central angle
⇒ Area = 3.14 × 50² × (45/360)
= 3.14 × 2500 × 1/8
= 7850/8 = 981.3 cm²
Answer:
<h2>The coordinates will be (-8, -6), (-4, -6), (10, 8), (6, 8).</h2>
Step-by-step explanation:
As per the given image, the co-ordinates are, P(-4, -3), Q(-2, -3), R(5, 4) and S(3, 4).
Since, the scale factor is 2 and centered at the origin, we need to multiply the co-ordinates with 2 in order to get the co-ordinates of the figure after dilation.
Hence, the co-ordinates will be
P = (-8, -6)
Q = (-4, -6)
R = (10, 8)
S = (6, 8).

Step-by-step explanation:
Complete the square
+ 2x - 13 = 0
+ 2x = 13
+ 2x + = 13 +1 (take 1/2 of the b term , the 2 )
+ 2x + 1 = 14
(x +1)^2 = 14
