In the figure below O is the centre, angle and angle OMP=160. Find the angles marked x, y and z.
. The frequency distribution table below shows the marks obtained by students in a form four class.
On the grid provided below, draw a histogram to represent the information shown above.
The marked price of a car in a show room is sh.650000. The car is sold at a discount of 5% through an agent who earns a commission of 8% on the selling price. Find how much the owner earns.
. Find the inverse of the matrix
hence solve the simultaneous equations
and that A and B are obtuse angles, Calculate the value of the following without using tables or calculator
. A game park lies between three points A,B and C. Point A is 50km from B. Point C is 70km from B and 60km from A respectively. Calculate the area of the ranch to the nearest whole numbers.
SECTION II (45 Marks)Attempt ONLY five questions from this section
Villages A,B,C and D are such that B is 40km due east of A, C is 30km on a bearing of 1450 from B, and D is 40km S 500W of C. a) Using a suitable scale, draw a diagram to show the positions of the villagers. (3mks)
b) Use your diagram to determine i) The bearing of A from D. (1mk)
ii) The distance of A from D (1mk)
iii) The shortest distance between B and the line AD. (2mk)
c) A vertical mast of the height 100m stands at B. Another vertical mast of height 30m stands at a point on the line BC, 200m from B. Find the angle of elevation of the top of the taller mast from the top of the shorter mast.
A particle moving at a velocity of 12m/s accelerates to a velocity of 25m/s in the first 10 seconds, it then moves at a constant velocity for the next 30 seconds before coming to rest in another 20 seconds.
a) Draw a velocity- time graph to represent this information.
9. In a pentagon ABCDE, AB=4.3cm, BC=4.6cm, CD=7.2cm, DE=5cm, AE=6cm and angle BAE=1100. Diagonal BD is parallel to AE. a)
i) Construct the pentagon accurately. (5mks)
ii) Measure and write down the length of BD. (1mks)
b) i) Drop and measure a perpendicular from C onto AE. (1mk)
ii) Find the area of the pentagon. (2mks)
. a) A sum of Ksh.360 was to be divided equally among x homeless boys. An equal amount was to be shared among (x+4) homeless girls. This way, each boy would receive Ksh.3 more than each girl, calculate the amount to be received by each girl. (5mks)
b) But before the actual divisions were done, a well- wisher added Ksh.360 to
the boys kitty and Ksh.y to the girls pool, which made some boys to
dramatically cross-over to the girls side, making the boys group to be a
third of the ‘girls’ group.
i) Find the number of boys that defected to the girls’ side. (2mks)
ii) If each member in the two groups now received the same amount, find the value of y.

Calculate a) The slant height of the frustrum. (1mk)
b) The perpendicular height of the pyramid. (2mks)
c) The surface area of the frustrum. (4mks)
d) The volume of the frustrum. (3mks)

a) Find angle PAB. (2mks)
b) Find the length of PM. (2mks)
c) Calculate the area of quadrilateral APBC. (3mks)
d) Hence find the area of the shaded region. (3mks)
