Answer:

$We \: need \: to \: find \\ the \: differential \\ coefficient \: of \: the \\ function \: x2logxsinx \\ with \: respect \: to \: x. \\Let \: y=x \: 2logxsinx \\ We \: need \\ to \: find \: dxdy. \\Consider \\ y=x \: 2logxsinx \\ dxdy=dxd(x2)logxsinx+x2dxd(logxsinx) \\ =2x(logxsinx)+x2[sinxdxd(logx)+logxdxd(sinx)] \\ =2x(logxsinx)+x2[xsinx+logxcosx] \\ dxdy=2x(logxsinx)+xsinx+x2logxcosx$

Harold and Millicent are getting married and need to combine their already-full libraries. If Harold, who has 1/2 as many books

slavikrds [6]

Answer:

2/3

Step-by-step explanation:

Let x be the number of books that Millicent has. So the number of books that Harold has is x/2. And the number of book that Harold is bringing to the new home is (x/2)/3 = x/6.

The home has enough room for another half of Millicent's books, which is x/2. So the total books capacity of the new home is

$\frac{x}{6} + \frac{x}{2} = \frac{x}{6} + \frac{3x}{6} = \frac{4x}{6} = \frac{2x}{3}$

Since x is also the number of books in Millicent's old library capacity, we can conclude that the fraction of Millicent's old library capacity to the new home's library capacity is 2/3, or 2 thirds

Solve for x I need help again :/

vovangra [49]

Answer:

x = 6

Step-by-step explanation:

opposite sides of both angles are congruent/equal or have same measure.

Therefore:-

6x+2=38

6x=38-2

6x=36

x = 6

What is the point of intersection when the system of equations below is graphed on the coordinate plane? -x+y=4 6x+y= -8

kvasek [131]

A) -x+y=4
B) 6x+y= -8
Multiplying "A" by -1
A) x -y = -4 then adding it to B
B) 6x + y = -8
7x =-12
x = -12/7 = -1.7142857143
y = 4 + x = 2.2857142857

Did you make a typo because as you can see, the solution is not one of the 4 choices.
