Answer:
8
Step-by-step explanation:
Nth term of a geometric sequence is given as:
...(1)
Plugging n = 9, a = 3 and r = 2 in the above equation, we find:
... (2)
Comparing equations (1) & (2), we obtan:
(n - 1) = 8
For a school play, the maximum age for a youth ticket is 18 years old. The minimum age is 10years old. Write an absolute value e
1 answer:
We have been given that maximum age for a youth ticket is 18 years old and minimum age is 10 years old.
Our first step is to find average age, that is, mid point of maximum and minimum. That would be
Difference between the average (mean) from maximum or minimum is |14-10|=4
Therefore, the required absolute value equation for which two solutions are the maximum and minimum ages for a youth ticket would be:

Answer:
Th Range is [0, -∞)
Step-by-step explanation:
f(x) = 2 - x
w(x) = x - 2
We want to find the range of (f * w)(x).
First, we need to find (f * w)(x), which is the multiplication of the function f(x) and the function w(x). Lets use algebra to find (f * w)(x):
This is a quadratic function (U shaped), or a parabola. The graph is attached.
The range is the set of y-values for which the function is defined.
We see from the graph that the parabola is upside down and the highest value is y = 0 and lowest goes towards negative infinity. So the range is from 0 to negative infinity. Or,
0 < y < ∞
In interval notation, that would be:
[0, -∞)
