Answer:
Therefore,

Step-by-step explanation:
Simplify
-2^3

It is read as negative 2 raised to the power three,
also it is the cube of negative 2
we know that
given as

so for negative a i.e -a

substituting a = 2 we get

negative sign multiplied by odd number of times then the sign remains negative.
Therefore,

Given,
Rate of free fall = 216 km/h
Solution,
km/h to m/s is converted as follows :

So, the rate of fall is 60 m/s.
If t = 20 s
Assume, initial velocity = 0
It will move under the action of gravity.
Using equation of motion,

Hence, this is all for the solution.

Answer: 3y3+7y2+−4y+3
Step-by-step explanation:
3y2+y3+−5+4y2+−4y+2y3+8
Combine Like Terms:
=3y2+y3+−5+4y2+−4y+2y3+8
=(y3+2y3)+(3y2+4y2)+(−4y)+(−5+8)
=3y3+7y2+−4y+3
