Answer:
Rule: If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
Step-by-step explanation:
Your job here is to simplify 9t-4>32, in which the variable (t) is already positive. Here you do NOT switch signs or reverse the direction of the inequality symbol. Adding 4 to both sides, we get 9t > 36, or t > 4.
If, however, you had -9t-4>32 to work with, the situation would be different because t in this inequality is negative. Adding 4 to both sides results in:
-9t > 36. To solve for t, we must divide both sides by -9 AND reverse the direction of the inequality symbol:
t < -4.
Rule: If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
Answer:
A = 0 +/- nπ radians , where n is an integer.
Step-by-step explanation:
cos 2A = cos^2 A
Use the identity cos 2A = 2 cos^2 A -1 :
2cos^2 A - 1 = cos^2 A
cos^2 A = 1
Cos A = +/-1
When cos A = 1, A = 0 +/- 2nπ radians.
when cos A = -1, A = π +/- nπ radians.

Answer:
$ 51.59
Step-by-step explanation:
Nate has shares worth $ 36.85.
He says that the value of these shares increased by $ 2 plus 40% of their original value, therefore the final value would be as follows:
$ 2 + $ 36.85 * 0.40 = $ 2 + $ 14.74 = $ 16.74, was the increase.
The sale value was of this increase plus the original value, therefore:
$ 36.85 + $ 14.74 = $ 51.59
Nate sold the shares at a value of $ 51.59.
