Answer:
A rational expression that has the nonpermissible values
and
is
.
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of
, the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
(1)
Then, the factorized form of
must be:
(2)
If we know that
, then the rational expression is:
(3)
A rational expression that has the nonpermissible values
and
is
.
The answers to the questions are
- The mathematical model is given as s = −16t2 + 1054
- The height after 4.5 seconds is 730 feet
- the time it would take to strike the ground is 8.11 seconds.
<h3>How to solve for the position of the object</h3>
The mathematical model of this problem would be written as
s = −16t2 + v0t + s0
s0 = 1054
then we would have
s = −16t2 + 1054
b. after 4.5 seconds the height is going to be
s = −16t2 + 1054
= −16(4.5)² + 1054
= -16 * 20.25 + 1054
= 730
C. the time that it takes to strike the ground
s = −16t² + 1054
= 16t² = 1054
t² = 1054/16
= 65.88
t = √65.88
t = 8.11
Hence the time it would take to strike the ground is 8.11 seconds.

Answer:
The function f(x) when x=x-4 is
or 
Step-by-step explanation:
Given function f is defined by 
Now to find the function f(x-4):

Put x=x-4 in the above function we get

(using the formula
)

(adding the like terms)


Therefore
