Answer:

Step-by-step explanation:
Given

Required
Approximate to the nearest ten thousand
First, identify the digit at the ten thousand position
From the given numbers of visitors, the digit is 2.
So, the next digit (which is 7) will be approximated and added to 2.
7 > 5. So, 1 will be added to 2.
The number of visitors becomes:

Answer:
D 21.80°
Step-by-step explanation:
Let x = measure of the angle
Tan x = 12000/30000 = .4
Arctan .4 = 21.80°
Answer: The correct option is (2) (a, b).
Step-by-step explanation: We are given to find the co-ordinates of the point 'P' for the rectangle shown in the figure without using any new variable.
Since we are dealing with a rectangle, so each of its angle is a right angle. Hence, each side of the given rectangle is perpendicular to its adjacent side.
Also, the distance of a point from a line is the length of the perpendicular drawn from the point to the line.
So, we can see from the attached figure below that
Point 'P is at a distance of 'b' units from X-axis and 'a' units from Y-axis.
The distance of a point 'P' from Y-axis is its x co-ordinate the distance of 'P' from X-axis is its y co-ordinate.
Therefore, the co-ordinates of the point P will be
(distance of P from Y-axis, distance of P from X-axis)
= (a, b).
Thus, the correct option is (2) (a, b).
