At the point
, we have

Denote by
the partial derivative of a function
with respect to the variable
. We have

The Jacobian is

By the chain rule,






Answer: the same length for one of the other two legs.
It doesn't matter which leg since the triangles could be rotated. If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
Answer:
Step-by-step explanation:
The area = 252 in²
One side = 14 in
The other side = x
The area of a rectangle is a product of 2 sides
- 14x = 252
- x = 252/14
- x = 18 in
Mixing is a physical reaction, which does not change any chemical properties of elements and molecules because it does not change the number of protons.
It is the number of protons that determine the unique properties of each element (hence why the periodic table sorts elements by increasing the number of protons).
Answer:
Depends
Step-by-step explanation:
IF Line KM is an angle bisector of K & a line bisector of JL, then JKL is an isosceles triangle (that is, if only JK and JL are congruent, and KL is not congruent to the other 2 sides).
