Answer:
The equation is not a function.
Step-by-step explanation:
We are given that


Function: It is mapping between the values of two sets A and B.
Each element of A has unique value in set B.
By definition of function
In given function
y has no unique value for each value of x.
Substitute x=0

Hence, it is not a function.
To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used:
r = sqrt( x^2 + y^2)
<span>θ = tan^-1 (y/x)
</span>
Substituting (-3,3) accordingly to the equations, we obtain r equal to 3*sqrt(2) and θ equal to -π/4. Thus, the polar coordinates equivalent to (-3,3) is (3*sqrt(2), -π/4).
Answer:
669.9 ft³
Step-by-step explanation:
The formula for volume of a cone:


The radius is 8; the height is 10.
From here, we can just plug the numbers into the formula.

≈ 
24. 9×4=36 4×-3=12 so 36+(-12)=24
