Step 
<u>Find the value of MN</u>
In the right triangle MNL
Applying the Pythagorean Theorem

Solve for MN

in this problem we have

Substitute in the formula above



Step 
<u>Find the value of cos (M)</u>
we know that
In the right triangle MNL

Substitute the value of MN

therefore
<u>the answer is</u>
The value of cos(M) is 
I think the correct answer is J
Answer:
y=2^x - 5
Step-by-step explanation:
"- 5" demonstrates a verical shift 5 units down
Answer:
y = 
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 7 when x = 3
k =
=
, thus
y =
x ← equation of variation
When x = 7, then
y =
× 7 = 
the final temperature was -2 F, and that reflects a drop of 13 units, so
-2------0------------------------------------------------------+11.
