Answer:
its a negative correlation and a traingle the a nd c are farther apart then the m and n
Step-by-step explanation:
To solve this problem, let us first assign variables. Let
us say that:
x = volume of 67% herbicide solution
y = volume of 46% herbicide solution
The total volume should be 42 liters therefore:
x + y = 42
x = 42 – y --> 1
The component mass balance on the pure herbicide would
be:
0.67 x + 0.46 y = 0.55 (42) --> 2
Substituting equation 1 to 2:
0.67 (42 – y) + 0.46 y = 23.1
28.14 – 0.67 y + 0.46 y = 23.1
- 0.21 y = - 5.04
y = 24 L
Calculating for x using equation 1:
x = 42 – 24
x = 18 L
Therefore we only need 18 L of the 67% herbicide
solution.
Answer:
A. 18 L
In order to have a linear equation, you have to write an equation like
The sequence has to start with 3, so we must choose 
, because this guarantees that when 
we have
Now, 
must be even. In fact, if is even, 
will always be even for every possible 
, and 
will be odd.
So, for example, you might choose
Which will produce the following sequence:
and so on
14 + x < = 3x....ur inequality
***
the sum means add....so the sum of a number and 14 is 14 + x
is less then or equal....< =
3 times the number....3x
