Answer:
x = 55.6
Step-by-step explanation:
Recall the 3 main trig functions
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
Note that hypotenuse = longest side length
We want to find angle "x".
We are given its opposite side length ( 19 ) as well as the adjacent side length
When dealing with the opposite and adjacent we use tan
Tan = Opp / Adj
Opp = 19 and Adj = 13
Tan(x) = 19/13
* take the inverse tan of both sides *
x = 55.6
Answer:

Step-by-step explanation:
To find the inverse of this function, you need to replace the location of the x and the y.
You start with
. Now, replace the x and the y, and try to isolate the y.

Hope this helps!
Answer:
Option A (0,a)
Step-by-step explanation:
we know that

Is a exponential function
where
a is the initial value
b is the base
Remember that
The initial value is the value of the function when the value of x is equal to zero (y-intercept)
therefore
For x=0


The y-intercept is the point (0,a)
