Answer:
42in :)
Step-by-step explanation:
All you have to do is multiply 7x6 because u need to find the area.
but if u wanna find the perimeter u have to add all sides.
area is multiply 2 sides.
We should find the number of possible ways the student can arrange 4CD from total 20 CDs. We should find the number of combinations.
Combination is a way of selecting r items (CDs) from a set (collection) of n items (CDs). The order of selection of the items does not matter in this situation.
In our case: r=4 , n=20
The formula is: C=n!/(n-r)!*r!=20!/16!*4!=20*19*18*17*16!/16!*4!=20*19*18*17/4*3*2=116280/24=4845
4 1/4 - 3 3/4 = 1/2
Sarah picked 1/2 pound more than Nathan
Answer:
yes
Step-by-step explanation:
Answer:
- Amplitude is -5
- Period is 2π
- phase shift is -2π
Step-by-step explanation:
We can write a general wave function equation as:
Where:
- A is the amplitude .
- 2π/B is the period
- C is the phase shift
- D is the vertical shift
Our equation is:
Hence, comparing both equation we will conclude:
- Amplitude is -5
- Period is 2π
- phase shift is 2π
I hope it helps you!
