In the diagram, PR is a diameter of the circle PQRS. PST and QRT are straight lines. Find QRS
20o
25o
30o
35o
Correct answer is B
< PSR = \(\frac{1}{2}\)(180o) = 90o (angle substended by a semi-circle)
∴ < TSR = 90o
< SRT = 90o - 30o = 60o
< PRS = 90o - 35o = 55o
< PRQ = 180 - (60o + 55o) = 180 - 115o = 65o
< SQR = 35o(angles in the same segment)
< QSR + < SRQ + < SQR = 180o
< QSR + 120o + 35o = 180o
< QSR + 155 = 180o
< QSR = 180o - 155o
= 25o
x \(\leq\) 0, y \(\leq\) 0, 2y + 3x \(\leq\) 6
x \(\geq\) 0, y \(\geq\) 3, 3x + 2y \(\geq\) 6
x \(\geq\) 2, y \(\geq\) 0, 3x + 2y \(\leq\) 6
x \(\geq\) 0, y \(\geq\) 0, 3x + 2y \(\geq\) 6
Correct answer is A
m = \(\frac{y_2 - y_1}{x_2 - x_2} = \frac{3 - 0}{0 - 2} = \frac{-3}{2}\)
= \(\frac{y - y_1}{x- x_1}\)
m = \(\frac{y - 3}{x}\) \(\geq\) \(\frac{-3}{2}\)
2(y - 3) \(\geq\) - 3x = 2y - 6 \(\geq\) - 3x
= 2y + 3x \(\leq\) 6 ; x \(\leq\) 0, y \(\leq\) 0
In the venn diagram, the shaded region is?
(P \(\cap\) Q) \(\cup\) R
(P \(\cap\) Q) \(\cap\) R
(P \(\cap\) Q1) \(\cap\) R
(P \(\cap\) Q1) \(\cup\) R
Correct answer is C

N2050
N2600
N3100
N3450
Correct answer is A
360º - (60º + 60º + 67º + 50º = 237º)
360º - 237º = 123º
B. Salary = \(\frac{123}{360}\times N6000\)
= N2,050
