Answer:

N(-2) = \frac{n(-2)\\}{2}-5       this is also equal to n=2.5

Step-by-step explanation:

multiply both sides by 2

Solve for x. 9 4 13.5 x+4
Lady_Fox [76]

Answer:

x = 2

Step-by-step explanation:

The parallel lines divide the transversals into proportional segments, that is

\frac{x+4}{13.5} = \frac{4}{9} ( cross- multiply )

9(x + 4) = 54 ( divide both sides by 9 )

x + 4 = 6 ( subtract 4 from both sides )

x = 2

PLEASE HELP ASAP!!!!!!!
liraira [26]

Answer:

Step-by-step explanation:

If t=3 or t=6 take the 3 and replace it for t. d(3)= 4.9(3)^2= 44.1 so with that answered you can now narrow the answer down to A. and C. so if we go back to the question the coin was dropped from the top of a building that then narrows it down to C.

Finf the exact value of sin A and cos A where a = 9 and b = 10 and <c is a right angle
Katyanochek1 [597]
To solve for the longest side, the hypotenuse, you have to use the pythagorean theorem. It will be 10^2 + 9^2 = c^2. 100 + 81 =c^2. 
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)
