A rectangle is a two-dimensional shape where the length and width are different.
The length and width of the larger rectangle are 4.8 cm and 8.4 cm.
The area of the larger rectangle is 40.32 cm².
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Two similar rectangles:
Smaller rectangles:
Length = 4 cm
Width = 7 cm
Larger rectangles:
Length = 4.8 cm
We need to find the width of the larger rectangle.
Since the two rectangles are similar.
4 cm = 4.8 cm
Multiply 7/4 on both sides.
7/4 x 4cm = 7/4 x 4.8 cm
7 cm = 8.4 cm
Now,
Larger rectangle:
Length = 4.8 cm
Width = 8.4 cm
Now,
The area of the larger rectangle:
Area = Length x width
Area = 4.8 x 8.4
Area = 40.32 cm²
Thus,
The area of the larger rectangle is 40.32 cm².

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.
