Answer:
9.836
Step-by-step explanation:
Answer:
(a)Total volume, P(m) = 10000 + V(m) - E(m)
(b)P(m)=10000+19.9m
Step-by-step explanation:
The partially filled pool has 10,000 liters of water in it.
The pool is being filled with a hose, which means it adds to the volume of water. Therefore, V(m) is an addition to the total volume.
Water evaporates from the pool, which is a reduction to the volume of water. Therefore, E(m) is a subtraction from the total volume.
Therefore:
The Volume of Water in the Pool at any time, P(m) = 10000 + V(m) - E(m)
(b) Since we are given:
V(m)=20m
E(m)=0.1m
P=10000+20m-0.1m
The Total Volume, P(m)=10000+19.9m
Answer:
D
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
The x- coordinate of the point of intersection is approximately 5.5
Finding the slope, you get [4-(-2)]/[-1-2]=6/-3 = -2
Plugging (2,-2) and -2 into the formula y=mx+b, you get that -2=-4+b.
Therefore, b=2, making the equation y = -2x+2
