R = (-1) + (-2) = -3
S = (-4) + (1) = -3
T = (-6) + (-3) = -9
Answer: $447.04
Step-by-step explanation:
Amount (A) = Simple interest + Principal,
Simple interest = (Principal * rate * time)
A = (P * r * t) + P
Principal (P)= $440
rate (r)= 32% or 0.032 as a decimal

Answer: f(t) = 15 - 1.1t
Step-by-step explanation:
Let t represent the number of hours since the candle was lit.
A 15-inch candle is lit and burns at a constant rate of 1.1 inches per hour. This means that in t hours, the candle that would have burnt is 1.1t
The length of the candle that would be left after t hours is expressed as
15 - 1.1t
suppose f is a function such that f(t) represents the remaining length of the candle (in inches) t hours after it was lit, then
f(t) = 15 - 1.1t
