Saying as there are 3 meals a day and there is 30 pounds of food and she feeds 1 pound a meal, the answer should be 30 meals
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
The answer is A.All real numbers except -2.
Add a point at (0.-2) then go down 3 and put another point connect the dots thats it
Step-by-step explanation:
H=√d^2-w^2
=√146.4 1-92.16
=7.3 inches
the principle used here is pythagoras theorem
all the best.
