Answer:
The depth of the water in the pool is 2.4 metres
Step-by-step explanation:
The Volume of Water in the Pool= 3000m³
Length of the Pool=50m
Width of the Pool=25m
Height=?
Volume of a Rectangular Prism= Length X Width X Height
3000= 50 X 25 X Height
3000= 1250H
H=3000/1250
Therefore, the Height of water in the pool = 2.4m
The water in the pool is 2.4 metres deep.
Answer: A=100(12)t5.27
Step-by-step explanation:
Assume / and ^ got lost from eqns.
A(t) = initial × (1/2)^(t/halflife)
So initial = 100, halflife = 5.27,
A=100(12)t5.27 means A=100(1/2)^(t/5.27)
so that A is 50 when t is 5.27
Answer:
m=

Gladly!
To find the slope, we need to find the change between <em>point a</em> and <em>point b</em>
With the difference between x1 and x2 being 4, and the difference between y1 and y2 being 1, we get a fraction that looks like this,
This right here is the slope of the line. Hope this helps!
