To solve the problem you must know that to change from Cartesian to polar coordinates you must write:
x = rcos (θ)
Where "r" is the radius
Likewise y = rsin (θ)
Therefore, in the expression r = 3cos (θ) one can write r as:
r = x / cos (θ)
So:
x / cos (θ) = 3cos (θ)
x = 3cos ^ 2 (θ)
The same for y ...
y = rsin (θ)
y = 3cos (θ) sin (θ).
Finally the correct answer is option 2.
x = 3cos ^ 2 (θ) y = 3cos (θ) sin (θ).
You need to divide 320000 by 2 since the speed was divided by 2. The final answer is ...... 160000 Joules.
I hope this helped!!!! :D
Answer:
123°
Step-by-step explanation:
Since, measure of minor arc is equal to the measure of its corresponding central angle.
Measure of central angle = 123°
So,? = 123°
Answer:
y= -x-5
Step-by-step explanation:
m=1-(-5)/-4-2
m=-1
-1= -x
y=-x-5
Answer:
4/5 is the slope
Step-by-step explanation:
the formula is y=mx +b
m = slope
b= y intercept
Therefore, the slope in 4/5
