using pythagorean theorem
a^2 + b^2 = c^2
(12x)^2 + (16x)^2 = 10^2
square each term
144x^2 + 256x^2 = 100
combine like terms
400 x^2 = 100
divide by 400 on each side
x^2 = 1/4
take the square root on each side
x = 1/2
Answer: x=1/2
A. 6
B. –6
C. –30
D. 30
B. a number greater than 4
C. a multiple of 3
D. an even number
Answer:
An equation whose variables are polar coordinates is called a polar equation.
Step-by-step explanation:
Polar Equation--
A polar equation is a equation that describe the relationship between r and θ, where r is the distance from the pole to a point on a curve and θ is the angle subtended by that point with respect to the x-axis.
Hence, here r,θ acts as a variable of the equation.
So, we can change any rectangular equation in terms of variable x and y into the polar equation in terms of variable r and θ by using the transformation:
x=r cosθ and y=r sinθ.
