<h2>See the explanation.</h2>Step-by-step explanation:
a.
The initial length of the candle is 16 inch. It also given that, it burns with a constant rate of 0.8 inch per hour.
After one hour since the candle was lit, the length of the candle will be (16 - 0.8) = 15.2 inch.
After two hour since the candle was lit, the length of the candle will be (15.2 - 0.8) = 14.4 inch. The length of the candle after two hours can also be represented by {16 - 2(0.8)}.
Hence, the length of the candle after t hours when it was lit can be represented by the function, .
at t = 20.
b.
The domain of the function is 0 to 20.
c.
The range is 0 to 16.
Answer:
Coordinates of other end point L = ( -19, 13 )
Explanation:
The mid point of the coordinates (a,b) and (c,d) is given by
Here we have (a,b) = (1,-7) and = (-9,3) , we need to find (c,d).
So coordinates of other end point L = ( -19, 13 )
