Find the coordinates of point B
(0,11/2)
(O,2)
(2,0)
(11/2, 2)
(11/2, 0)
Correct answer is E
B occurs at the point y = 0.
When y = 0, we have
4x + 3(0) = 6
4x = 6
x = 1\(\frac{1}{2}\)
B = \((1\frac{1}{2}, 0)\)
The shaded portion shows the outer boundary of the half plane defined by the inequality
4x + 3y \(\geq\) 6
4x + 3y = 6
4x + 3y < 6
3y >6
4x < 6
Correct answer is A
The region is denoted by 4x + 3y \(\geq\) 6
Find the perimeter of the region
22cm
33cm
40cm
47cm
66cm
Correct answer is C
P = \(\pi\)r + \(\pi\)r + R = \(\frac{22}{7}\) x 7 + \(\frac{22}{7}\) x \(\frac{7}{2}\) + 7
P = 22 + 11 + 7 = 40cm
Find the area of the enclosed region, PXROY correct to the nearest whole number
96cm2
116cm2
154cm2
192cm2
385cm2
Correct answer is A
Area of the bigger semi circle P x RO =
2nd Area of the smaller circle DYO =
Total Area = 77 + 19.25 = 96.25 = 96.00
41.2%
18.3%
5.3%
1.7%
1.4%
Correct answer is A
Error =12.75 - 7.50 = 5.25
Error % = \(\frac{5.25}{12.75}\) x 100% = 41.2%
