Answer:
$14,080
Step-by-step explanation:
You can use a formula for exponential decay, but since it is only 2 years, you can find 80% of the original value, and then 80% of the new value.
Original value: $22,000
Value after 1 year: 80% of $22,000 = 0.8 * $22,000 = $17,600
Value after 1 year: $17,600
Value after 2 years: 80% of $17,600 = 0.8 * $17,600 = $14,080
Answer: $14,080
Answer:
The correct option is C) $145,000
Step-by-step explanation:
Consider the provided regression.
![y=82 +7x](https://tex.z-dn.net/?f=y%3D82%20%2B7x)
sales y in $1000 and advertising x in $100
We have given that they spent $900 in advertising.
That means substitute x=9 in above regression because x is in $100.
![y=82 +7(9)](https://tex.z-dn.net/?f=y%3D82%20%2B7%289%29)
![y=82 +63](https://tex.z-dn.net/?f=y%3D82%20%2B63)
![y=145](https://tex.z-dn.net/?f=y%3D145)
It is given that y in $1000.
That means the total sale is 145×$1000=$145000.
Hence, the correct option is C) $145,000

Step-by-step explanation:
The degree of a polynomial is determined by the value of the largest exponent of the variable.
Given
4x + 2x³
The largest exponent is 3, thus the polynomial is of degree 3
A polynomial of degree 3 is called a cubic
