11. The given equation in rectangular coordinates is
To convert to polar form, use the relation
This implies that:
In polar coordinates, is a circle with radius 4 units.
12. From the diagram;
We can see that two arrows are moving in anticlockwise direction to meet A which is moving in the clockwise direction;
13. The conjugate of the complex number: is
Part a) The given complex numbers are:
and
The conjugates of these complex numbers are:
and
Part b) The product of and is
The conjugate of the product is:
Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
(3x + 3 + 4x + 2) = 13
(7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
Fish A is 2 inches and fish B is 4 inches
Answer:
Step-by-step explanation:
<h3>
The complete exercise is attached.</h3><h3>
</h3>
The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
Then, you can notice that it can be obtained by multiplying the dimensions of the rectangle.
Knowing this, you can determine that the total area of the two flowers bed can be obtained by adding the products of their dimensions.
Since one of the rectangular flower bed is 2.78 feet by 4.81 feet and the other bed 2.78 feet by 5.61 feet, you can write the following expression to find the total area (in square feet)of the two beds:
If you factor out 2.78:
or
Therefore, the expression that does not represent the total area in square feet of the two beds, is:
