Yes because it is the amount you are studying.
Answer:
<h2>S=33000-2000t</h2>
Step-by-step explanation:
Step one:
Let A be the altitude of the plane
Hence we can define a function that represents this scenario.
the rate at which the plane's altitude decreases is
=33000-17000/8
= 16000/8
=2000
The rate of decrease is 2000 ft per minute.
Thus for anytime "t" the expression for the altitude is
S=33000-2000t-------where t is the time in minute.
say we want to find altitude after 12 minutes
then t=12
substitute in the expression we have
S=33000-2000(12)
S=33000-24000
S=9000ft
(5,22.45),(7,25.45)
slope = (25.45 - 22.45) / (7 - 5) = 3/2 or 1.5
y = mx + b
slope(m) = 1.5
use either of ur points...(5,22.45)...x = 5 and y = 22.45
now sub and find b
22.45 = 1.5(5) + b
22.45 = 7.5 + b
22.45 - 7.5 = b
14.95 = b
so ur equation is : y = 1.5x + 14.95.......this means that each quart of oil costs $ 1.50 and the labor fee costs $ 14.95
