a. 0.03 0.3 __________ 30 __________ __________
Since is a positive a value (4) we know that the graph opens upward. -5 represents how far up or down the “vertex” is of the absolute value graph. This means that the range is -5
Answer:
The formula is:

Step-by-step explanation:
The geometric sequences are those in which the division between the terms
and
of the sequence are equal to a constant common reason called "r"
The geometrics secencias have the following form:

Where
is the first term of the sequence
In this sequence we have the following terms
1.2, 3, 7.5, 18.75
Then notice that:

Then:
and 
Finally the formula is:

Answer:
No real solutions;

Step-by-step explanation:
The easiest method to solve an algebraic equation is to use inverse operations. This applies to the given equation;

- Take the square root of both sides
==================================================================
As one can see, the right side is a negative number. However, one cannot take the square root of a negative number and get a real result. Therefore, one must use imaginary numbers. Remember, the imaginary unit (
) represents (
).
==================================================================

- Add (3) to undo the (-3)

- Divide by (2) to remove the coefficient of (2x)
