A function is for every input, you get 1 output
so sale items purchased to cost
if bought 1 then paid c (original cost)
if bought 2 then paid c ( buy 1 get one)
so it is a functinon because it is only not a function if
bought x and pay y or z, can only be 1
so it is a functnion
First, you need to know how many gallons will be in the tank after 1 hour. So:
Answer:
It is not a right triangle
Step-by-step explanation:
A triangle has side lengths of 8 inches, 12 inches, and 16 inches.
To determine if it is a Right Triangle, we make use of the Pythagoras Theorem, i.e.
Now the Hypotenuse is always the longest side
The equality above is not true and in fact
Therefore the 3 numbers do not satisfy Pythagoras theorem and cannot be the lengths of a right triangle.
The polar coordinate of any point can be written as:
(r, θ) = (r, θ + 2nπ) when positive
(r, θ) = [ - r, θ + (2n + 1)π ] when negative
The polar coordinates of this given point P is: P = (r, θ) = (5, π/3).
When the value of r is positive, the polar coordinate is written as P= (5, π/3) = (5, π/3 + 2nπ)
When the value of r is negative, the polar coordinate is written as P = (5, π/3) = [ - 5, π/3 + (2n + 1)π] where n is any integer.
Therefore all polar coordinates of point P are (5, π/3 + 2nπ) and [ - 5, π/3 + (2n + 1)π ].
