Answer:
- 1675.38
Step-by-step explanation:
In 2017, the vakue of the kitchen equipment was $14550
V(0)=$14550
Its value after then was modelled by 
We are required to find the rate of change in value on January 1, 2019






In 2019, i.e. 2 years after, t=2
The rate of change of the value

=
= - 1675.38
Answer:
Polynomial equation is x² - 16
Her pay if x = 12 is $128
Step-by-step explanation:
This week, Kyara worked x + 4 hours
She is paid x - 4 dollars per hour
She earned (x + 4)(x - 4) = x² - 16 dollars this week
Her pay if x - 12 is;
12² - 16 = $128
Step-by-step explanation:
present temprature outside=10 degree
temp drops every hour= 5 dgree
let number of hours=h
10 9 8 7 6 5 4 3 2 1 0 hours
--l----l----l----l-----l----l-----l-----l-----l----l----l----l----l-----------
-40-35 -30 -25 -20-15 -10 -5 0 5 10 degrees
it will take 10 hours
for the temperature below -40 degree
h=10
