Answer:
for me it was d=3.2t+0.6
Step-by-step explanation:
but to find the part where they intersect its (0.75,3)
We have
2x+3y=5
Step 1
find two points of the line
for x=0--------------> y=5/3 point (0,1.67)
for y=0 --------------> x=5/2 point (2.5,0)
The vector between two points is v =(2.5-0,0-1.67)=(2.5.-1.67)
Vector form: r=ro+tv----------> (2.5,0)+(2.5,-1.67)t
Parametric form
x=2.5+2.5t
y=-1.67t
the answer is
x=2.5+2.5t
y=-1.67t
1 gallon = 3.785 liters
Water in pool = 8000 x 3.785
Water in pool = 30,280 liters
Chlorine dosage = 2.5 mg / liter
Chlorine = 2.5 x 30,280
Chlorine = 75,700 mg
To the nearest thousand milligram:
Chlorine = 76,000 mg
Answer:
Step-by-step explanation:
12981 to the nearest thousand
2 is in the the thousands place
to the right of 2 is 9 and it is higher than 5
that means 2 becomes a 3 and the hundreds, tens and ones are zeros
13,000
