Possible rational zeros are:
Step-by-step explanation:
We need to list all possible zeroes of the function 
using rational zero theorem.
The rational zero theorem.
rational zero theorem states that zeros can be found by dividing the factors of constant term called p by the factors of the leading co-efficient called q i.e
p/q
In our given function
p = 7
q = 5
Factors of p (7) = ±1, ±7
Factors of q (5) = ±1, ±5
So, possible rational zeros are:

Answer:
a) 40 hours
b) 60 hours
C) 100 hours
Step-by-step explanation:
0.2a + 0.3b+0.5c = 76
Hence: 0.2* (0.2 λ) +0.3*(0.3 λ )+0.5*(0.5 λ ) = 76
0.38 λ =76
λ = 76/0.38 =200
Thus : 40, 60, 100
Answer:
- Inverse Variation
- Equation: 
Step-by-step explanation:
Given
X-> 2 | 4 | 8 | 12
Y-> 6 | 3 | 3/2 | 1
Required
- State the type of variation the table represents
- Determine the equation to model the data
To check for type of variation; we'll make use of trial by error method.
To start with; We'll check for direct variation.
This is done using the following expression;
where k is the constant of variation
Make k the subject of formula
When Y = 6, X= 2
When Y = 3, X = 4
There's no need to check further as both values of k are not equal
To check for inverse variation;
Make k the subject of formula
When Y = 6, X= 2
When Y = 3, X = 4
When Y = 3/2; X = 8
When Y = 1, X = 12
Note that for all values of X and Y, K remains constant;
Hence, the table represents an inverse direction
To determine the equation;
We make use of
Substitute 12 for k
So, the equation becomes
Reorder
Hence, the equation is
