Answer: -0.500
Step-by-step explanation:
If we're given a function, to find the slope of the function at a particular point, we have to first find the derivative of that function by differentiating once with respect to x and imputing the given value of x in our derivative.
To get the slope of f(x), we find the derivative of the function and input our value of x in the derivative.
Remember if f(x)=kx^n,
then, f'(x) = derivative of f(x) = k* n* x^n-1
F(x)= 2[x^-1]
F'(x) = 2*( -1)* [x^-2]
F'(x) = -2/x²
At x=2,
F'(x) = -2/2² = -2/4 = -0.500(3d.p.)
Answer:
45) Option A
- This is because every option has different modes and 70 is the mode and only one option has the mode as 70.
Hence, option A is correct.
46) Option B
- In all the options, the mode and medians are same hence we only have to find the mean which will help us to reach our correct option. The mean will be 40/17 = 2.35
Hence, option B is correct.

I believe it would be A. copying a segment, because with a parallel line the lines will not be intersecting, and copying the segment would be the only answer to give you lines that don't intersect.
