Answer:
The function has 2 zeros:
![x = -1 - \frac{1}{\sqrt{3}}\\x = -1 + \frac{1}{\sqrt{3}}](https://tex.z-dn.net/?f=x%20%3D%20-1%20-%20%5Cfrac%7B1%7D%7B%5Csqrt%7B3%7D%7D%5C%5Cx%20%3D%20-1%20%2B%20%5Cfrac%7B1%7D%7B%5Csqrt%7B3%7D%7D)
Step-by-step explanation:
When you have a polynomial function, you can identify the grade of the function (the grade is the maximum potency) and this is the number of zeros that the function will have. In this case, you have a second-grade polynomial function that has 2 zeros.

EXPLANATION
The problem represents a geometric progression.
The general form of a geometric sequence is:
![a_n=ar^{n\text{ - 1}}](https://tex.z-dn.net/?f=a_n%3Dar%5E%7Bn%5Ctext%7B%20-%201%7D%7D)
where a = first term
r = common ratio
The first term from the table is the first price (for the first month). That is $80.00
To find the common ratio, we divide a term by its preceeding term.
Let us divide the price of the second month from the first.
We have:
![\begin{gathered} r\text{ = }\frac{72}{80} \\ r\text{ = 0.9} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20r%5Ctext%7B%20%3D%20%7D%5Cfrac%7B72%7D%7B80%7D%20%5C%5C%20r%5Ctext%7B%20%3D%200.9%7D%20%5Cend%7Bgathered%7D)
The price after the 8th month is the value of a(n) when n = 8
So, we have that:
Answer: Zero and Any real number
Step-by-step explanation:
Point Q could be represented by any real numbers. And zero if it's located at the origin. The same is applicable to value at point P. It's just that at P, the value can't be equal to Zero.
Answer:
your answer is B
Step-by-step explanation:
your question is asking the y and x intercepts in other words where your line crosses the x and y axis respectively therefore your x is positive 2 and your y is -5
(2,0) and (0,-5)
Answer:
Earns 56,500
Tax 56,500 × 10/100
=5,650
Invest = 50,850 × 50/100
= 25,425
Food = 25,425 × 30/100
=7,627.5
Shopping = 17,797.5 × 20/100
=3,559.5
Remaining = 14,237.5
