One of the equations for a circle is (x - h)² + (y - k)² = r² where (h, k) are the center and r is the radius.
So after substitution:
(x + 6)² + (y - 2)² = 100
Notice the equation has the opposite of h and k and 100 is the result of squaring 10.
The answer is B.
ln both sides to clear the 'e' and bring 'a' out of the power.
Answer:
4.732 grams
Step-by-step explanation:
2 US fluid ounces is exactly 59.147059125 mL of volume. 8% of that volume is 4.73176473 mL.
For a solution of this type, where 1 g/100 mL is considered a 1% solution this is the number of grams of solute needed.
About 4.732 grams of solute are needed to prepare 2 fl oz of 8% solution.
_____
We have assumed that 1 gram of solute gives you 1 gram of iodine. Depending on the exact solute used, that may or may not be the case.
A)
no solutionB)
infinite solutionsC)
x = -36D)
x = 0
has infinite solutions, which is your answer.
Parallel means lines that never meet, and perpendicular are lines that meet at right angles.
