The polynomial can't be factored because they are all rational numbers.
Answer:
x = 1
Step-by-step explanation:
Line of symmetry: x = h,
Where h is the x-coordinate of the vertex
We are given
Clare is paid $90 for 5 hours of work
Total money paid =$90
total hours of work =5 hours
so, firstly we will find rate of work
rate of work = ( total money paid)/( total hours of work)
now, we can plug values
and we get
The rate of work is
![=\frac{90}{5}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B90%7D%7B5%7D)
$/ hour
now, we have to find time for amount paid is 25 cents
so, amount paid =25 cents
100 cents =1$
so, amount paid =$ 0.25
Since, the rate is constant
so, we can take same rate here
now, we can use formula
rate of work = ( total money paid)/( total hours of work)
now, we can plug values
![18=\frac{0.25}{T}](https://tex.z-dn.net/?f=18%3D%5Cfrac%7B0.25%7D%7BT%7D)
now, we can solve for T
hour
since, T is in hours
so, we can change into seconds
1 hour =3600seconds
so, we can plug
seconds
