Answer:
x = 1 and x = 9
Step-by-step explanation:
the known solutions are simply the values of x which causes the SAME number to show up in f(x) and g(x).
if we go down the table, we see that for x = 1, the same number 14 shows up for both f(x) and g(x), hence x=1 is a solution.
the same occurs for x = 9 giving 6 as the same solution for f(x) and g(x)
no other values of x causes this to occur.
hence the 2 known solutions are x = 1 and x = 9
Answer:
Yes
Step-by-step explanation:
Given

True or false? With reason
The expression is true and the reason is as follows.
In trigonometry:

So:

is equivalent to:
![0 * [tan(1).tan(2).......tan(89)] = 0](https://tex.z-dn.net/?f=0%20%2A%20%5Btan%281%29.tan%282%29.......tan%2889%29%5D%20%3D%200)
When 0 is multiplied to an expression, the result is 0
So, the above expression becomes:

<em>Since both sides of the equation are equal, then Ravi is correct</em>
