300,000,000 is 3 x 10 to the 8th power
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).
Answer:
D.16.5m
because circumference=21/7×5.25
=16.5m
Answer:
its an isosceles triangle which means that the sides a and c are the same
so C is the correct answer!!
Step-by-step explanation:
Answer:
D)
Step-by-step explanation:
Because
a) 10 = 2(5) = 10
b) 10 = 5 + 5 = 10
c) 10 = 15 -5 = 10
d) 10 = 5 - 5 = 0 the result is not equivalent
