X=3.5 add 10 and divide by 8
The explicit formula would be

.
This is a geometric sequence, since we are multiplying each term by a constant to find the next term.
The explicit formula for a geometric sequence is given by

,
where g₁ is the first term and r is the common ratio, or the number that is multiplied to get the next term.
Our first term is 5, and the common ratio is 3.
Answer:

Step-by-step explanation:
<u>Operation of Functions</u>
Given:


The sum of (f+g) (x) is:

We cannot operate with the expression inside the absolute bars, thus:

We use a conjecture that says that the perpendicular bisector of a chord in a circle passes through the center of the circle.
The distances of the two bisectors are the same so the chord lengths are the same.
b = half of 22.5 = 11.25
The answer to your question is 11.25.
To find the equation take the slope 2/3
y-y(1)=m(x-x(1)
y-4=2/3(x-8) = 2/3x-16/3
Next solve for y
y=2/3x-16/3 +4(turn 4 into a fraction with a common denominator)
y=2/3x-16/3 + 12/3
y=2/3x-4/3
