R = 2 / (1 + sin <span>θ)
Using the following relations:
R = sqrt (x^2 + y^2)
sin </span>θ = y/R
<span>
R = 2 / (1 + y/R)
R</span>(1 + y/R<span>) = 2
</span><span>R + y = 2
R = 2 - y
sqrt(x^2 + y^2) = 2 - y
Squaring both sides:
x^2 + y^2 = (2 - y)^2
x^2 + y^2 = 4 - 4y + y^2
x^2 + 4y - 4

Answer:
6
Step-by-step explanation:
Think of it as a ratio. The recipe calls for 2:3. If Jason used 4, then you need to match the other side.
4/2=2
So you need to multiply 3 by 2 to find the match.
3x2=6
The ratio is 4:6, so Jason uses 6 teaspoons of baking powder.

Answer:5
Explanation:Pythagorean Theorem
Answer:
A is the answer.
Step-by-step explanation:
What you do is you multiply -6 into each of the fractions and then add or minus the fractions together.
-6(1/4x)=-3/2x
-6(-2/3x)=4x
-6(5/6x)=-5x
-3/4x+4x-5x=-2.5 or A.
Answer:
Chlorine, Krypton, Argon, Fluorine, Hydrogen
Step-by-step explanation:
Look at the numbers and sort them from least to greatest. It could be the opposite answer to since the larger the negative number the smaller the value.
