Answer:
As cosine returns a value between -1 and 1, the amplitude will simply be the coefficient of the cosine function. In this case it's 2.3, which tells us that the amplitude is also 2.3
There are four different ways to fold the square in half, however there are no different ways to fold the letter G.
A square has four symmetry lines.
Each symmetry line splits the square in half.
This indicates that the square can be folded into one half along any of its lines of symmetry.
As a result, there are four different methods to fold the square in half.
There is no symmetry line in the letter G.
This indicates the letter can't be folded such that the two parts are exactly aligned.
As a result, there are no methods to fold the letter G.
Answer:
No
Step-by-step explanation:
Because 6, 6 and 10 are not Pythagorean triplets.
Hence, it is not a right triangle.
![{10}^{?} = 100...(1) \\ {6}^{2} + {6}^{2} = 36 + 36 = 72..(2) \\ from \: (1) \: and \: (2) \\ {10}^{2} \neq {6}^{2} + {6}^{2}](https://tex.z-dn.net/?f=%20%7B10%7D%5E%7B%3F%7D%20%20%3D%20100...%281%29%20%5C%5C%20%20%7B6%7D%5E%7B2%7D%20%2B%20%20%7B6%7D%5E%7B2%7D%20%20%20%3D%2036%20%2B%2036%20%3D%2072..%282%29%20%5C%5C%20from%20%5C%3A%20%281%29%20%5C%3A%20and%20%5C%3A%20%282%29%20%5C%5C%20%20%7B10%7D%5E%7B2%7D%20%20%5Cneq%20%7B6%7D%5E%7B2%7D%20%20%2B%20%20%7B6%7D%5E%7B2%7D%20)
Answer:
Part 1: B
Part 2: D
Step-by-step explanation:
Let
x-----> the time in minutes
y------> the number of gallons of water
we know that
the unit rates is equal to
![\frac{y}{x} = \frac{42}{10}=4.2\frac{gal}{min}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D%20%3D%20%5Cfrac%7B42%7D%7B10%7D%3D4.2%5Cfrac%7Bgal%7D%7Bmin%7D)
the unit rate is equal to the slope of the linear equation
then
![y=4.2x](https://tex.z-dn.net/?f=y%3D4.2x)
<u>Problem</u>
1) How many gallons of water will Elyse use in three minutes in the shower?
For x=3 minutes
substitute in the equation above
![y=4.2x](https://tex.z-dn.net/?f=y%3D4.2x)
![y=4.2*3](https://tex.z-dn.net/?f=y%3D4.2%2A3)
![y=12.6 gal](https://tex.z-dn.net/?f=y%3D12.6%20gal)
<u>the answer is</u>
12.6 gal
