Answer:The function is a direct variation function with a constant
of variation of 1.5.
Step-by-step explanation:
It would be 20.4 km because if 1cm is 12km then you just have to multiply 1.7 x 12 = 20.4.
Ts option A
cos C = (b - x) / a
a cos C = b - x
x = b - a cosC
Answer:
The image shows the graph for given function.
Step-by-step explanation:
We are given the following information in the question:

It is clear function is an exponential function and have shape similar to exponential function.
An exponential function is of the form:
,
where b is a parameter of the function and read as b raised to the power x.
The exponential function enjoys the following properties:
- If 0 < b < 1, then the graph decreases as we move from left to right.
- If b > 1, then the graph will increase as we move from left to right.
