If the cylinder already has 3.6 Liters in it, adding 600 mL would make the cylinder have 4.2 Liters of water in it.
We know this because 600 mL converted to Liters equals 0.6 L. So 3.6 L + 0.6 L = 4.2 Liters.
I just learned this, I believe that the answer is <span>a1=21;an=7⋅an−1</span>
Answer:
Second option
Third option
Fourth option
Step-by-step explanation:
We have the following quadratic function

Use the distributive property to multiply the expression


For a function of the form
the x coordinate of the vertex is:

Then in this case the coordinate of the vertex is:


To obtain the y coordinate of the vertex we evaluate the function at 



Then the vertex is: (-3, -16)
We can see in the graph that the zeros of the function are x=1 and x=-7
Then the function is decreasing from -∞ to -3 and then it is increasing from -3 to ∞
The function is positive for
and 
The correct answers are:
Second option
Third option
Fourth option
