Answer:
Perimeter =
Step-by-step explanation:
Let the length of a rectangle is l and width is w.
Then the expression which represents the perimeter is
P = 2(l + w)
It is given in the question length of the rectangle = l and width = x
and l =
By replacing these values in the expression for the perimeter
P =
=
=
Therefore, expression that represents the perimeter of the rectangle will be
Perimeter =
Answer:
a) "ascend"
Step-by-step explanation:
a)
The equation is
This question is asking for the value of the directional derivative in the direction of -j [since south that's y negative]
So, this is the negative of partial derivative of y. Thus we have:
Now we are at (100,120,1106), we take y value of 120 and put it in the partial:
We take the negative, that is -(-2.4) = 2.4
Since this is positive, we can say the hill is sloping upward at this point, so you will start to ascend.
Answer:
Step-by-step explanation:
Start by finding the LCM of the coefficients of each polynomial:
Next, to find the least common multiple of each of the following terms, we need to take the absolute minimum we can of each term (,
, and
). The largest term of
is
in the first polynomial, so we'll take exactly that for our
term in the LCM, absolutely nothing more. Similarly, the largest term of
in any of the three polynomials is
(also in the first polynomial) and the largest
term in any of the three polynomials is
in the second polynomial. Thus, the LCM of all our polynomials is:
