Answer:
The linear function is;
Tn-1 = Tn + 3
What this mean is that to get the term before the present term, we add 3 to the present term
Step-by-step explanation:
Here, we want to write a liner function to describe the function
As we can see from the numbers listed,
the next term is simply obtained by deducting 3 from the previous term
We can write this as:
Tn-1 = Tn + 3
Where Tn is the next term and Tn-1 is the previous term
What the function is saying is that to get the term before the present term, we add 3 to the present term

Answer:
(d) 30 units²
Step-by-step explanation:
The area of the rectangle is the product of the length and width. It is equal to the number of unit squares that fill the rectangle.
__
By counting grid squares or subtracting coordinates, we can see this rectangle is 3 units wide and 10 units high. Its area will be ...
A = WH
A = (3 units)(10 units) = 30 units²
_____
<em>Additional comment</em>
You can also count the three columns of 10 shaded squares, or the 10 rows of 3 shaded squares. Either way, you will count 30 square units covering the rectangle.
It will take 0.556 seconds for an echo to reach one's ears
<h3>Calculating the time to hear an echo</h3>
From the question, we are to determine how long it would take an echo to reach one's ears
From the formula,
NOTE: To hear an echo, the sound will travel to and fro, hence, it will cover twice the distance
From the given information,
Distance = 92.0 m
NOTE: Speed of sound in air at 0 °C ≅ 331 m/s
Putting the parameters into the formula, we get
Time = 0.556 secs
Hence, it will take 0.556 seconds for an echo to reach one's ears.
