Answer:
third quadrant
Step-by-step explanation:
quadrant III
Answer:
x = 3
Step-by-step explanation:
Using the rules of logarithms
ln x = ln y ⇒ x = y
ln e = 1
Given
2 ln e ln 5x = 2 ln 15 ( divide both sides by 2 )
ln e ln 5x = ln 15
ln 5x = ln 15, hence
5x = 15 ( divide both sides by 5 )
x = 3

<u>Question 14</u>
If a circle is inscribed in a square, then the diameter of the circle is equal to the side length of the square. Therefore, as the radius of a circle is half the diameter, the radius of the circle is half the side length of the square.
Given:
Therefore, the areas of the square and circle are:
Therefore, the ratio of the circle to square is:
So the circle is ¹/₄π the size of the square.
<u>Question 15</u>
If a square is inscribed in a circle, then the diagonal of the square is the diameter of the circle. Therefore, as the radius of a circle is half the diameter, the radius of the circle is half the diagonal of the square.
Given:
Therefore, the ratio of the circle to square is:
So the circle is ¹/₂π the size of the square.
