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
It would 100% be 5.
but my explanation is kind of by look, basically it is one more than the four and one less than the 6 :)
Answer:
6.05%
Step-by-step explanation:
Initial price = £198
Increased price = £209.99.
We need to find the percentage change in the price. It can be calculated as follows :
%=(increase in amount)/(initial price) × 100
Increase in amount = 209.99 - 198
= 11.99
So,
So, the increase in price is 6.05%.
Answer:
Step-by-step explanation:
(5x - 7)(-3x + 2)
The values inside of the parenthesis cannot be simplified, so distribute and multiply.
Distribute
(5x - 7)(-3x) + (5x - 7)(2)
Multiply
-15x² + 21x + 10x - 14
Add 21x to 10x
-15x² + 31x - 14
Hope this helps :)
