20 cats * ( 1 bag of food / 5 cats per month ) = 4 bags of food per month to feed all 20 cats
Answer: Option d.
Step-by-step explanation:
The trigonometric identity needed is:
Knowing that 
:
Substitute it into :
Simplify the expression:
Solve for 
. Apply square root at both sides of the expression:
Answer: The point (0,0)
This point is also known as the origin
The reason why is because every direct variation equation is of the form y = k*x
where k is some fixed number
If we plugged in x = 0 it leads to y = k*x = k*0 = 0. So (x,y) = (0,0)
A≈8
V Volume
Using the formula
V=a3
Solving fora
a=V⅓=512⅓≈8
Therefore, to find the lenght of an edge of the cube, just find the cube root of the volume. In this case, the cube root of 512 is equal to 8.
The cofunction identities for tangent are:
tan (90° – θ) = cot θ and cot (90° – θ) = tan θ
