(b) The angle of elevation of the top of a building from the top of a vertical pole is 30°. The pole is 2m high and its foot is 12m from that of the building. Find, correct to 2 d. p,the :
(I) height of the building,
(ii) angle of depression of the foot of the pole from the top of the building;
(iii) angle of elevation of the top of the pole from the foot of the building.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
