To find this you multiply 1.39 by 2.4. This gives you 3.336, which you round to 3.34. So it will cost $3.34
Hope this helps
Answer:
The answer is C. (a + -a = 0 )
Step-by-step explanation:
"The additive inverse of a number a is the number that, when added to a, yields zero"
Answer:
![A=45000(0.82)^t](https://tex.z-dn.net/?f=A%3D45000%280.82%29%5Et)
Step-by-step explanation:
Given data
P= 45,000
rate= 18%
Recall the expression for the compound interest
![A=P(1+r)^t](https://tex.z-dn.net/?f=A%3DP%281%2Br%29%5Et)
Since we are talking of depreciation
![A=P(1-r)^t](https://tex.z-dn.net/?f=A%3DP%281-r%29%5Et)
Substitute
![A=45000(1-0.18)^t\\\\A=45000(0.82)^t](https://tex.z-dn.net/?f=A%3D45000%281-0.18%29%5Et%5C%5C%5C%5CA%3D45000%280.82%29%5Et)
Hence the exponential function is
![A=45000(0.82)^t](https://tex.z-dn.net/?f=A%3D45000%280.82%29%5Et)

Answer:
![20,475\ ways](https://tex.z-dn.net/?f=20%2C475%5C%20ways)
Step-by-step explanation:
we know that
<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
To calculate combinations, we will use the formula
![C(n,r)=\frac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=C%28n%2Cr%29%3D%5Cfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D)
where
n represents the total number of items
r represents the number of items being chosen at a time.
In this problem
![n=28\\r=4](https://tex.z-dn.net/?f=n%3D28%5C%5Cr%3D4)
substitute
![C(28,4)=\frac{28!}{4!(28-4)!}\\\\C(28,4)=\frac{28!}{4!(24)!}](https://tex.z-dn.net/?f=C%2828%2C4%29%3D%5Cfrac%7B28%21%7D%7B4%21%2828-4%29%21%7D%5C%5C%5C%5CC%2828%2C4%29%3D%5Cfrac%7B28%21%7D%7B4%21%2824%29%21%7D)
simplify
![C(28,4)=\frac{(28)(27)(26)(25)(24!)}{4!(24)!}](https://tex.z-dn.net/?f=C%2828%2C4%29%3D%5Cfrac%7B%2828%29%2827%29%2826%29%2825%29%2824%21%29%7D%7B4%21%2824%29%21%7D)
![C(28,4)=\frac{(28)(27)(26)(25)}{(4)(3)(2)(1)}](https://tex.z-dn.net/?f=C%2828%2C4%29%3D%5Cfrac%7B%2828%29%2827%29%2826%29%2825%29%7D%7B%284%29%283%29%282%29%281%29%7D)
![C(28,4)=20,475\ ways](https://tex.z-dn.net/?f=C%2828%2C4%29%3D20%2C475%5C%20ways)
