Answer:
In a 24 pack of soda, 1/8 would be 3 cans (24/8 = 3). 1/12 would be 2 cans (24/12=2).
So 3/8 is 9 cans of soda and 5/12 is 10 cans of soda, so they are not equivalent because the number of soda cans is not the same.
A = 1/2 bh
A = 1/2 (21)(8)
A = 1/2 (168)
A = 84
X²+y²-2y=7
using the formula that links Cartesian to Polar coordinates
x=rcosθ and y=r sin θ
substituting into our expression we get:
(r cos θ)²+(r sin θ)²-2rsinθ=7
expanding the brackets we obtain:
r²cos²θ+r²sin²θ=7+2rsinθ
r²(cos²θ+sin²θ)=7+2rsinθ
using trigonometric identity:
cos²θ+sin²θ=1
thus
r²=2rsinθ+7
Answer: r²=2rsinθ+7
Answer:
A. x = 0, x = -3, x = 2, and x = -2
Step-by-step explanation:
by moving the terms on the left side to the right side
factor an 
from 
and factor - 4
from 
the equation becomes :
= 0
take 
as a common factor the equation becomes :
= 0
thus
⇒
and
by factoring an x we get :
⇒ = 0 and 
⇒
and 
Thus
the values are :
x = 0, x = -3, x = 2, and x = -2
