Answer:

7.5 is 37.5% of 20.

Step-by-step explanation:

Solve for %

We know that ; % = given no. ÷ total no. × 100

Where, we've

Given number = 7.5
and Total number = 20

plug the values

$\small \sf \frac{7.5}{20} \times 100 \\$

canceling 100 by 20 to get

7.5 × 5

multiply the numbers

37. 5 %

Which of the following parametric equations are equivalent to the polar equation r=3 cos theta

Allushta [10]

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).
