Answer:
The value of f(x) when x=-1 is 0.5
Therefore 
Step-by-step explanation:
Given that y=f(x)=
to find the f(x) when x=-1 :
That is to find f(-1)
Put x=-1 in the given function f(x)=



Therefore 
The value of f(x) when x=-1 is 0.5
Answer:
its yes
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
b/c the figure is right angle
If you mean the gradient then it would be -3/2 because if you multiply the 2 together they equal minus 1. That’s how u figure out if 2 lines are perpendicular
The question is an illustration of right-angled triangles
The approximated value of x is 33.5 degrees
The given parameters are:



To determine the measure of angle x, we simply make use of the following sine ratio.

So, we have:


Take arc sine of both sides

This gives

Hence, the approximated value of x is 33.5 degrees
