Cosine of an angle is the adjacent leg divided by the hypotenuse. 

So cos(60) = a / 12

I'm going to assume it's your last option because it's not in the picture.

Yes SOH-CAH-TOA, Cos= Hypotenuse+Adjacent, so, cos(60) a/12 would be the correct answer so D.

What is the solution of this system of equations?
I am Lyosha [343]
<span>First we have to find the slopes, we need it in the slope intercept form for this:
2x - 3y = -5; this is the standard form
-3y = -2x - 5
Get rid of all those negatives, multiply eq by -1
3y = 2x + 5
Divide by 3 to get y
y = x + 
The slope of this equation (m1) is </span>

Work out the formula for the nth term of the<br> quadratic sequence:<br> 19, 15, 9, 1...
Leto [7]

Answer:

Tn = -n^2 - n + 21 is the formula for the nth term.

Step-by-step explanation:

The second differences are all equal in this quadratic sequence.

Now, the quadratic sequence has a formula of Tn = an^2 + bn + c

Find the value of a in an^2 by dividing the difference by 2:

-2/2 = -1

a = -1

Since T1 is 19 and T2 is 15 we can put that into the equation and simplify:

b + c = 20

2b +  c = 19

Thus, b = -1 , c = 19 and the general formula for the nth term is Tn = -n^2 - n + 21
