\sin^2x\cos^2x=\left(\dfrac{1-\cos2x}2\right)\left(\dfrac{1+\cos2x}2\right)=\dfrac{1-\cos^22x}4=\dfrac{1-\dfrac{1+\cos4x}2}4=\dfrac{2-(1+\cos4x)}8=\dfrac{1-\cos4x}8

I need help now I don't get this
Darina [25.2K]
The answer is $1.80.  You would take 25% of 3, which is 75, and subtract it from 3.  That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25.  That leaves you with a grand total of $1.80.  Hope that this helped!

While in flight, a hot air balloon decreases its elevation by 83 2/5 meters and then increases its elevation by 83.7 meters
Pachacha [2.7K]

An inequality which compares the changes in elevation of this hot air balloon while in flight is given by L - 83 2/5 ≤ L ≤ L + 83.7.

<h3>What is an elevation?</h3>

An elevation is also referred to as an altitude and it can be defined as the vertical distance (height) above a natural satellite or the surface of planet Earth such as land or sea level.

This ultimately implies that, an elevation (altitude) simply refers to the vertical height (elevation) of an object or physical body above a particular location or planetary reference plane such as land or sea level on planet Earth.

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments (symbols):

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

For this exercise, let the variable L represent the initial height of this balloon. Also, since the hot air balloon decreased its elevation by 83 2/5 and increases its elevation by 83.7 meters, we have the following:

  • The lower limit is equal to: L - 83 2/5.
  • The upper limit is equal to: L + 83.7.

In this context, an inequality which models the changes in elevation of this hot air balloon is L - 83 2/5 ≤ L ≤ L + 83.7.

What’s the correct answer
PolarNik [594]
The correct answer would most likely be option C. This is because the lowest tip was on 5, thus we can eliminate B and D.

And during this time the slope almost remained stationary, minimal change.

3. A new bag of golf tees contains 10 red tees, 10
maw [93]

Answer: 0.2308

Step-by-step explanation:

A new bag of golf tees contains 10 red tees,10 orange, 10 green tees, and 10 blue tees. You empty the tees into your golf bags.What is the probability of grabbing out two tees of the same color in a row for you and your partner?

# of ways to succeed:: 4(10C2) = 4*45 = 180 ways

# of random pairs:: 40C2 = 780

P(2 of same color) = 180/780 = 0.2308

Therefore your answer is 0.2308

I hope this helps! :)
