Answer:
n= 578 + 1160 x2
Step-by-step explanation:
I think--
<u>Part a)</u> If both ants skate directly towards each other, starting at the same time and skating the same speed, what will be the coordinates of their meeting place?
Let
A(3,4) B(33.44)
we know that
If both ants skate directly towards each other, starting at the same time and skating the same speed
then
the coordinates of their meeting place is the midpoint AB
<u>Find the midpoint AB</u>
in the x-coordinate
(3+33)/2=18
in the y-coordinate
(4+44)/2=24
the midpoint AB is (18,24)
therefore
<u>the answer Part a) is </u>
the coordinates of their meeting place is (18,24)
<u>Part b)</u> How far will each ant skate?
<u>Find the distance AB</u>

substitute the values

units
units
<u>Find the half distance AB</u>
50/2=25 units
therefore
<u>the answer part b) is</u>
Each ant will skate 25 units
The region is a segment of a circle with radius √2 lying above the line
. In polar coordinates, this line has equation

and the circle has equation

The two curves meet when

Then the same integral in polar coordinates is

The original perimeter is 22 cm.
If both sides are doubled, the length would be 16 cm and the width would be 6 cm.
The perimeter would be 44 cm.
22/44 is 50%.
