Step-by-step explanation:
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: 1.1
Step-by-step explanation:
If Sam buys 14 water bottles, he will have spent 18.9, so when you subtract 20 (the limit) from 18.9 (how much money he'll spend on the water bottles) you get 1.1
Answer:
y=2x-3
Step-by-step explanation:
The slope-intercept form of the original equation would be y=3/8−x/2
Therefore, the slope of the perpendicular line would be m=2
Then, the y-intercept would be 7=(2)x(5)+a
A=-3
Answer:
y=2x+3
Answer: 5 lattes
Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.
Answer: 100,000 + 2000 + 200
