Hi there! We can find the value of x by using this equation.
If you remember, tanx = opposite/adjacent. We focus on the angle x currently.
Now that you might wanna ask if there is a value of x that makes 19/23. The answer is yes but in decimal.
You might wanna put arctan(19/23) in a calculator since it's not really possible to get the square root like value by yourself.
arctan(19/23) is 0.69
Then we round up and get 0.7
Hence, the value of x ≈ 0.7
Answer
- x ≈ 0.7 (rounded)

Hope it helps, and Happy Learning! :)
The exponential equation is
An exponential function is represented as:
The base is 3.
So, we have:
It is stretched vertically by 2/3.
So, we have:
When reflected over the y-axis, we have:
An asymptote of y = 2, makes the function becomes
Lastly, it passes through the point (0, 3.5).
So, we have:
This gives
Subtract 2 from both sides
Multiply by 3/2
Take the logarithm of both sides
log(2.25) = h * log(3)
Solve for h
h = 0.74
Substitute h = 0.74 in
Hence, the exponential equation is
