F(3) = -18
G(5) = 97
Explanation: substitute 3 for x.
-5(3) - 3 = -18
Substitute 5 for x
4(5) ² - 3 = 97
Answer with Explanation:
Keep in mind these trigonometric Identity:
1. Cos²x - Sin² x= Cos 2 x
2. Cos 2 x = 2 Cos²x-1
3. Cos 2 x = 1 - 2 Sin²x
Now, Coming to the Problem
1 + Cos (18 x)
= 1 + Cos (2 × 9 x)
= 2 Cos ² (9 x)→→→ Cos (2 × 9 x)= 2 Cos² (9 x) - 1
Answer:
<u>The correct answer is D. Watching TV.</u>
Step-by-step explanation:
Watching television is an activity that is not oriented to organic survival, it is not an activity that takes place daily, nor is it aimed at the care and maintenance of the human body itself. Actually, you can survive indefinitely without watching television daily. On the other hand, every human being needs to dress, eat breakfast and walk to the bathroom every day.
<u>The correct answer is D. Watching TV.</u>
A set of pencils sells for 1.75 and costs 0.40 to make
if 500 sets are sold...
500(1.75) = 875...this is revenue
500(0.40) = 200....this is expenses
profit = revenue - expenses
profit = 875 - 200
profit = 675
20% of the profit goes to the school...
0.20(675) = $ 135 <=== this is what goes to the school
Area of a rectangle is length times width:
3 to the (2 over 3) power is ∛3²
A=∛81*∛3²
A=3∛3 * ∛3²=3∛3³=3*3=9
the answer is C.
