Which expression is equivalent
to cos(4x)?
Answer: A 2(2cos^2(x) - 1)^2 - 1
Step-by-step explanation: E 2020
The expression equivalent to cos(4x) is 2cos²(2x) - 1.
Out of the options provided, the correct choice is 2cos²(2x) - 1.
The expression equivalent to cos(4x) can be found using trigonometric identities and formulas. One such identity is the double angle identity for cosine:
cos(2θ) = 2cos²(θ) - 1.
We can apply this identity to the expression cos(4x) by considering it as cos(2(2x)).
Using the double angle identity, we have:
cos(4x) = cos(2(2x)) = 2cos²(2x) - 1.
Therefore, the expression equivalent to cos(4x) is 2cos²(2x) - 1.
Out of the options provided, the correct choice is:
O 2cos²(2x) - 1.
By substituting 2x for θ in the double angle identity, we obtain the equivalent expression for cos(4x).

Answer:
27/50
Step-by-step explanation:
Just do 9/10/3/5
Answer:If the question is asking for 9/10/3/5 the answer is 3/50; however, if the question is asking for (9/10) / (3/5), the answer should be 3/2.
Step-by-step explanation: The 3/50 answer comes from 9/10 which equals .9, dividing that by 3. That equates to .3, and then dividing by 5 which measures up to .06. From there you can turn .06 into a fraction being 3/50.
You get the 3/2 by dividing (9/10) by (3/5). .9/.6 is 1.5. When converted to a fraction 1.5=3/2. Hope this could help.

A leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours. After the leak is fixed, the height of the water is 4.75 feet. The equation 4.75 = x + (negative 0.25) can be used to find x, the original height of the water in a pool.
What was the original height of the water in the pool in feet?
Answer:
Assuming the leak took 2 hours to fix, the original height of the pool is 5 feet.
Step-by-step explanation:
This is probably the most simple "high school" problem I've seen in a while. All you have to do is move the negative 0.25 to the other side to isolate x. That gives you 4.75 + 0.25, or 5 feet.
The original height of the water in the pool was 5 feet.
Given that there is leak in a pool causes the height of the water to decrease by 0.25 foot over 2 hours.
After the leak is fixed, the height of the water is 4.75 feet.
The equation 4.75 = x - 0.25 can be used to find x, the original height of the water in a pool.
we need to find the original height of water,
To find the original height of the water in the pool, we can use the given information and equation.
Let's break down the equation: 4.75 = x - 0.25
Here, x represents the original height of the water in the pool, and -0.25 represents the decrease caused by the leak.
The equation states that after the leak is fixed, the height of the water in the pool is 4.75 feet. This means that the final height (4.75 feet) is equal to the original height (x) minus the decrease caused by the leak (-0.25 feet).
To solve for x, we can isolate it on one side of the equation.
Adding 0.25 to both sides of the equation, we get:
4.75 + 0.25 = x - 0.25 + 0.25
Simplifying the equation, we have:
5 = x
Therefore, the original height of the water in the pool was 5 feet.

Complete the following problems.
Amy has $50 in her lunch account. Amy spends $3 a day for lunch. Amy's mother receives a notification when Amy's
account balance reaches $5 or lower. How many lunches can Amy purchase until her mother receives a notification? And what is the equation in slope intercept form
Answer:
Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.
Step-by-step explanation:
The balance Amy has in her lunch account is a function of the number of lunches she has consumed.
The initial balance is $50 and it decreases by $3 for every lunch Amy has. Thus, the function that models the balance in her lunch account is:
[tex]B(x)=50-3x[/tex]
Where x is the number of lunches.
Her mother receives a notification when the balance goes at $5 or lower, thus the condition that triggers the notification is:
[tex]B(x) \le 5[/tex]
Or, equivalently:
[tex]50-3x\le 5[/tex]
Subtracting 50:
[tex]-3x\le 5-50[/tex]
[tex]-3x\le -45[/tex]
Multiplying by -1 (and flipping the sign):
[tex]3x\ge 45[/tex]
Solving:
[tex]x\ge45/3[/tex]
[tex]x\ge 15[/tex]
Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.
Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 – 0.2x = 9.1 9.1 – 10 = 0.2x To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining. Which equations could you use to find the price of one tire patch? Select all that apply. 4x – 1.9 = 22.2 4x – 22.2 = 1.9 4x + 1.9 = 22.2 4x + 22.2 = –1.9 22.2 – 4x = 1.9
Given:
Different equations are given.
Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.
To find:
The equation which gives a different value of x than the other three.
To find the equations that could you use to find the price of one tire patch.
Solution:
In option A,
[tex]9.1 = -0.2x + 10[/tex]
[tex]0.2x= 10-9.1[/tex]
[tex]0.2x= 0.9[/tex]
Divide both sides by 0.2.
[tex]x=\dfrac{0.9}{0.2}[/tex]
[tex]x=4.5[/tex]
Similarly,
In option B,
[tex]10 = 9.1 + 0.2x[/tex]
[tex]0.9= 0.2x[/tex]
[tex]4.5=x[/tex]
In option C,
[tex]10-0.2x = 9.1[/tex]
[tex]-0.2x = -0.9[/tex]
[tex]x = 4.5[/tex]
In option D,
[tex]9.1 – 10 = 0.2x[/tex]
[tex]-0.9 = 0.2x[/tex]
[tex]-4.5 = x[/tex]
Since option D has difference solution, therefore the correct option is D.
Let price of one tire patch be x.
So, price of 4 tire patches = 4x
Remaining amount in Rhyan's gift card = $1.90
Total amount = $22.20
Price of 4 tire patches + Remaining amount in gift card = Total amount
[tex]4x+1.9=22.2[/tex]
It can be written as
[tex]4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9[/tex]
Therefore, the correct options are C and E.
