Answer:

Step-by-step explanation:

dy/dx = d/dx log root under x-1 / root under x+1

dy/dx = root under x+1 / root under x-1 * 1/(x+1)^2/3 * 1/root under x-1

dy/dx = (x+1)^2/ x-1

The area of a triangle is 15x^4+3x^3+4x^2-x-3 square meters. The length of the base of the triangle is 6x^2-2 meters. What is th

MArishka [77]

Answer:

The height of the triangle is: $H = (5x^2 + x +3)$

Step-by-step explanation:

Here, the area the triangle is given as: $15x^4 + 3x^3 + 4x^2 - x - 3$

Also, base of the triangle = $(6x^2 -2)$

Let us assume the height of the triangle = H units

Now, AREA of TRIANGLE = $\frac{1}{2} \times B \times H$

$\implies (15x^4+3x^3+4x^2-x-3 ) = \frac{1}{2} \times ( 6x^2-2) \times H\\\implies H =\frac{ (15x^4+3x^3+4x^2-x-3 )}{(3x^2-1)}$

Solving by LONG DIVISION, we get:

$H = (5x^2 + x +3)$

Hence, the height of the triangle is: $H = (5x^2 + x +3)$

loris book has 6 times more pages than sals book. the combined number of pages for the two books is 532. how many pages loris bo

julia-pushkina [17]

Your equation would be x+6x=532. You would add the "x's" together to get 7x=532. You would then divide each side by 7 resulting in x=76. This means Sal's book has 76 pages. To get Lori's book, you just times Sam's by 6 (76×6) which is 456. Lori's book has 456 pages.

forsale [732]

Answer:

Option b.

Step-by-step explanation:

Consider the below figure attached with this question.

A computer program selects blue,red,green as the background color each time the program is used.

Blue background = 12 times

Red background = 21 times

Green background = (45-12-21) times = 12 times

Blue background = Green background

Red background ≠ Green background

Green is just as likely as blue to appear, but not as likely as red.

Therefore, the correct option is b.
