Answer: option a.
Step-by-step explanation:
In polar coordinates we have that:
x = r*cos( θ)
y = r*sin( θ)
we know that x = 4 and y = 4. now let's analyze the options:
a) x = 4√2*cos(45°) = 4 nice.
y = -4√2*sin(225°) = 4 nice
Option a is correct
b) x = 4√2*cos(315°) = 4 nice
y = -4√2*sin(135°) = -4 incorrect
option b is not correct
c) x = 4√2*cos(135°) = -4 incorrect
Option c is not correct
d) x = 4√2*cos(225°) = -4 incorrect
option d is not correct
5,000.
Since 3 is less than 5, you round under.
Good luck!
The solution to this system is the line x + y = 5. Since the first
equation states that the quantity of (x+y) is greater than or equal to
5, while the second states that the same quantity of (x+y) is lesser
than or equal to 5, therefore the greater and less than parts are
contradictory, and the only possibly solution is that x + y = 5.
Answer:
y = -1/2x + 0
y = mx+b
