What is the value of A to the nearest tenth? (geometry)
2 answers:
Answer:
A. 12.9
Step-by-step explanation:
We have been given a circle and we are asked to find the measure of segment 'a'.
We will use intersecting chords theorem to solve our given problem. This theorem states that when two chords intersect inside a circle, then product of segments on each chord are equal.
Using above theorem, we can set an equation as:
Dividing both sides by 35, we get
Therefore, the value of 'a' is 12.9 and option A is the correct choice.

The correct option A: graph A, shows the logarithmic function;
f(x) = log₃x + 1
<h3>Explain the term logarithmic function?</h3>- The opposite of such an exponential function is a logarithmic function.
- A log function and then an exponential function both use the same base.
- An exponent is a logarithm. f(x) = bx is how the exponential function be expressed.
- The formula again for logarithmic function is f(x) = log base b of x.
f(x) = log₃x + 1
- When x = 1
f(1) = log₃1 + 1
f(1) = 0 + 1
f(1) = 1
(1, 1)
- When x = 3
f(3) = log₃3 + 1
f(3) = 1 + 1
f(3) = 2
(3, 2)
Thus, the graph must contain the points (1, 1), (3, 2).
Therefore, graph A define the given logarithmic function;
f(x) = log₃x + 1.
