Answer:
Step-by-step explanation:
8/3 = 2.6666 (repeating 6)
so rounded about 2.7 minutes per lap :)
We can plug in the values of this point to find b
-4 = 17 (3) +b
We will multiply 17 times 3
-4 = 51 + b
We then subtract by 51 on both sides
-55 = b
So the full equation will be
y = 17x - 55
If 
, then 
. You replace all x's in the function with -3.

Finish by evaluating the absolute value and then adding that to the 5 that's behind the absolute value.
Can you finish it from there?
Answer:
480m³
Step-by-step explanation:
The entire pool have the same depth which is 4metres
Since the pool is L shaped, we will find the volume of each part and add them together to get the volume of the entire pool.
Using the formula for calculating volume of a rectangular box
V = lwh
L is the length
w is the width
h is he height
For the first pool.
Length = 8m
Width = 6m
Height = 4m (depth)
Volume = 8×6×4
Volume = 192m³
For the other pool.
Length = 12m
Width = 6m
Height = 4m (depth)
Volume = 12×6×4
Volume = 288m³
Volume of the entire pool = 192+288 = 480m³
