X = -3
y = 3*sqrt(3)
r = sqrt(x^2 + y^2)
r = sqrt((-3)^2 + (3*sqrt(3))^2)
<span>r = sqrt(9+27)
</span><span>r = sqrt(36)
</span>r = 6
theta = arctan(y/x)
<span>theta = arctan(3sqrt(3)/(-3))
</span>theta = arctan(-sqrt(3))
theta = -60 degrees which is coterminal to 300 degrees
So the polar form is (r,theta) = (6, 300)
The use of ratio language was used in the following sentences:
For every 1 students out of school, there are 10 students in school
For every 5 apples John eats, he eats 20 boxes of chocolate
For every 5 minutes, study, I sleep for 1 hour
Ratio is used to show the relationship that exists between numbers. It shows the frequency of the number of times that value of one number is contained within the value of another number or numbers
For example, There are 3 apples and 20 oranges. If I want to express the relationship between apples and oranges as a ratio. The ratio will be 3 : 20 . It means for every 3 apples, there are 20 oranges.

Answer:
3/5y
Step-by-step explanation:
6y/35 ÷10y^2/7
to solve this you do reciprocal of 10y^2/7
then;
6y/35 x 7/10y^2
solving this
3/5y
there are 9 plates and x slices on each plate so 9x
Try this solution:
1. the standart form of the circle is: (x-x₀)²+(y-y₀)²=r², where point (x₀;y₀) - the cetre of the given circle, r - radius of the given circle.
2. Using r=7 and coordinates of the centre (0;0) it is possible to make up the required equation:
(x-0)²+(y-0)²=7²;
x²+y²=49.
