PLS HELP ME ASAP FOR 39 (SHOW WORK!) + LOTS OF POINTS!! *CORRECT ANSWER ONLY!*

Nady [450]

The straight line ON has the following equation :
(x - 18)/(x - 0) = (y - 12)/(y - 0)
Where (18,12) are coordinates of N and (0,0) are coordinates of O.
x - 18/x = y - 12/y
-18y = - 12x
y =12x/18 - - - - - (a)

The coordinates satisfy equation (a) are (7.5, 5)

Therefore D is the correct answer.

Good luck

Does 15/25 x 25/15 = 0?

sergejj [24]

No, it does not equal 0. Lets multiply it out and see what it actually equals.
15/25 * 25/15
15*25 / 25*15
375 / 375
Anything over itself is 1, so the final answer for the multiplication is 1.

Find an expression equivalent to 1-sinx ^2/1-cosx ^2

madam [21]

Answer:

cot²x

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1, then

1 - sin²x = cos²x

1 - cos²x = sin²x

Thus

$\frac{1-sin^2x}{1-cos^2x}$ = $\frac{cos^2x}{sin^2x}$ = cot²x
