Answer:
Geometric sequence
common ratio
1/8 (or 0.125)
Step-by-step explanation:
To get to the next number we have the mulitply the one before by 1/8
Because we are multiplying each time it's a geometric sequence
Because it's a geometric sequence we have a common ratio
I wrote before that to get to the next number we have to multiply it by 1/8 so that's the common ratio
 
        
             
        
        
        
In this case you divide 170 by 7 which = 24.29 so 24.29 is your answer, good luck.
        
             
        
        
        
Answer:

Step-by-step explanation:
f(x) = x² – 8 and g(x) = 4-x
y=f(x) - g(x)
y=(x² – 8) - (4-x)

 
        
             
        
        
        
A polynomial function of least degree with integral coefficients that has the
given zeros  
Given 
Given zeros are 3i, -1  and 0
complex zeros occurs in pairs. 3i is one of the zero 
-3i is the other zero
So zeros are 3i, -3i, 0 and -1
Now we write the zeros in factor form 
If 'a' is a zero then (x-a) is a factor 
the factor form of given zeros 

Now we multiply it to get the polynomial

4(x + 7) = 38
Since there is no operation sign between the 4 and parenthesis, it makes it an automatic multiplication problem.
You would use distributive property to multiply each which should leave your equation looking like this afterwards:
4x + 28 = 38
(4 times x and 4 times 7)
You would then solve it like a two step equation,
1. +28 - 28 = 0
2. 38 - 28 = 10
4x = 10
10 divided by 4 = 2.5
x = 2.5
We can recheck our work by substituting in the value of x.
4(2.5 + 7) = 38
10 + 28 = 38
When we substituted in the value, it gave us the correct inequality.
Therefore,
x = 2.5
