b
Step-by-step explanation:
The correct answer is C.
The limit in A does exist:
The limit in B also exists: for any ,
But this alone does not prove the 2D limit exists. only captures all the paths through the origin that are straight lines.
The limit in C also exists, but it's not the same as either of the limits along the paths used in A and B.
That this value is non-zero tells us the original limit does not exist.
The claim in D is generally not correct. That is undefined does not automatically mean the limit doesn't exist. A simpler example:
yet is undefined.
<span>$2.30 / 12 = 0.19 cents each
</span><span>$5.50 / 30 = 0.18 cents each
answer
</span><span>30 eggs for $5.50 is the better deal cause it only costs 0.18 cents / egg</span>
Answer:
The proof of Pythagorean Theorem in mathematics is very important. In a right angle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. States that in a right triangle that, the square of a (a²) plus the square of b (b²) is equal to the square of c (c²).
