Find the partial derivatives of the function w=4r2+6s2+
lyudmila [28]
I'm taking the liberty of editing your function as follows:  <span>w=4r^2+6s^2, where I use " ^ " to indicate exponentiation.

The partial of w with respect to r is 8r.  That with respect to s is 12s.</span>

is it possible to have a right triangle in which the sine of one of the angles is equal to the cosine of one of the angles? why?
stira [4]

Answer:

Yes , it is possible (see the explanation)

Step-by-step explanation:

we know that

In a right triangle, we have two complementary angles (their sum equal to 90 degrees)

so

If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa

<em>Example</em>

Suppose we have the right triangle ABC

The measure of angle C is 90 degrees

A and B are complementary angles

A+B=90°

therefore

sin(A)=cos(B)

sin(B)=cos(A)

Answer:

The 2nd case is the better value

Step-by-step explanation:

                                                       £11.45

Case 1:  That would be £11.45 + -------------- for the two shirts.  This comes

                                                             2

out to 1.5(£11.45) = £17.175 for two shirts.

Case 2:  Two shirts for £10.16 each comes out to £20.32; multiplying that by (1.00 - 0.20), or (0.80) results in (0.80)(£20.32) = £16.256.

The 2nd case is the better value, as one would get 2 shirts for £16.26, versus 2 shirts for £17.18 in the other case.
