KE=1/2mv^2
50000=(0.5)(1000)v^2
v^2=50000/500
v^2=100
v=10 ms^-1

an is the 'nth' term
a1 is first term
d=common difference (found by doing

)
n=numerical representation of which term

Answer:

Step-by-step explanation:
The given function is

To find the inverse of this function, we interchange x and y.

we now solve for y.

Take the sine inverse of both sides to obtain;

Hence the inverse of the given function is;

where 
A suitable calculator can row-reduce the augmented matrix.
first number: 3
