Answer:
(x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)
Step-by-step explanation:
The rule for CCW rotation through an angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
So, for α = 210°, the rule becomes ...
(x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)
D
7 minutes for 49 gallons
that means 1 minutes filled 7 gallon
multiply the time by 7, that is number of gallons for each time
By estimating. 5x700 is 3500. i multiplied the first digits in the equation.
The value of this is 12.32
