Answer:
f(x)=cscx
f(x+h)=csc(x+h)
f(x+h)−f(x)=csc(x+h)−cscx=1sin(x+h)−1sinx
=sinx−sin(x+h)sin(x+h)(sinx)
=2sin(x−x−h2)cos(x+x+h2)sin(x+h)(sinx)
=−2sin(h2)cos(2x+h2)sin(x+h)(sinx)
f′(x)=limh→0f(x+h)−f(x)h
=limh→0−2sin(h2)cos(2x+h2)hsin(x+h)(sinx)
=−limh→0sin(h2)h2×limh→0cos(2x+h2)sin(x+h)sinx
=−cosxsin2x
=−cscxcotx

Hi.
The first question is a direct variation — specifically y = 1.8x
In the second one (if my calculations are correct), it's not a direction variation.
Hope this helps :)
Calculations:
y = 1.8(3) = 5.4
y does not equal x, 2x, or -2x.
The range of the dataset = 47
What is the range of a dataset?
The range of a set of data is the difference between the greatest number and least number
The given data set is:
{14, 25, 61, 18, 30, 32, 28, 45, 21}
The greatest number = 61
The least number = 14
The range of the dataset = Greatest Number - Least Number
The range of the dataset = 61 - 14
The range of the dataset = 47

I think it is 16 because I just divided it, I’m sorry if you will get it wrong I’m not sure
Answer:
Step-by-step explanation:
Based on how the equation is described, the slope is
The point slope form is given by:
We substitute the point (-3,8) and the slope to get:
Hence the point-slope form is
