Answer:
y=sec(x) + 1
Step-by-step explanation:
The Sec(x) = 1/Cos(x) which has a minimum of +1 when positive, and -1 when negative. Adding +1 to it gives a range of (-∞,0) and when negative (2,∞)
1.) 29/5
2.) 233/25.
I hope it helps
Given:
The function is:

It is given that -1 is a zero of the given function.
To find:
The other zeroes of the given function.
Solution:
If c is a zero of a polynomial P(x), then (x-c) is a factor of the polynomial.
It is given that -1 is a zero of the given function. So,
is a factor of the given function.
We have,

Split the middle terms in such a way so that we get (x+1) as a factor.



Again splitting the middle term, we get



For zeroes,
.

and
and 
and
and 
Therefore, the other two zeroes of the given function are
and
.
Answer:
Option # C: 5
Step-by-step explanation:
Decision variables, as the name imply are entities that can have different values in the given scenario and which in turn produce different outcomes. For our question, the variables are the sizes of TVs available, as the production time and profit depend on the sizes. Hence, TV sizes (i.e. 5) are our decision variables.
Furthermore, it does not matter on which machine the TVs are being manufactured as they will take identical time for same TV size. Thus we do not consider the number of machines as our decision variables.
Ok...so u have 4 people sharing this plan...they each pay for their own data..however, the $ 90 flat rate is split between them equally.
90/4 = 22.5....so each of them pay 22.50 each for the flat rate.
so John's equation is : 22.5 + 0.25x = 147.50
