Answer:
ira can make 4 pizzas
Step-by-step explanation:
Answer:
The correct option is;
r = √(x² + y²)
θ = tan⁻¹(y/x)
Step-by-step explanation:
The rectangular coordinate of a complex number on the complex plane is given as (x, y)
Given that the complex number is represented by a point on the plane, we have;
The distance, r, of the point from the origin, (0, 0) is r = √(x² + y²)
The direction, θ, by which we rotate to be in line with the point on the complex number is given by tan⁻¹(y/x)
The answer to your question is c. y=4
Answer:
A.\ \ r(d)=-100(d-25)^2+122,500
Hope this helps!
(x + 5)(x + 2) = x^2 + 2x + 5x + 10 = x^2 + 7x + 10
middle term is 7x
