Formula for 270 degree rotations:
(x,y) -----> (-y,x)

So....

p: (-3,2)----> (-2,-3)
r: (2,5)------>(-5,2)
s: (0,0) ------> (0,0)

My question is

So 2 gallons every 5 minutes
2/5= .4
so .4 a minute
and you already have 5 gallons in so those need to be added
m=minutes
y=0.4m + 5 will be what you want to find out if you are looking to find out how much will be there in a certain time
for 50 minutes you will have
y=0.4(50) +5 
20+5
25 gallons
HOWEVER, the equation has to be changed if you want to tell how long you have to wait for it to fill.
m=2.5(g-5)
m=minutes
g= gallons
you subtract 5 because they are already there
you multiply by 2.5 because it fills at a rate of 1 gallon every 2.5 minutes.
m=2.5(1500-5)
for the sake of it being easier i will do the -5 separately
2.5(1500 = 3750
2.5(-5= -12.5
3750-12.5
3737.5 minutes to fill the pool.
3720/60 = 62
17.5/60 = .292
62.292 hours to fill the pool.
p.s. you have a really slow hose.
Its good you didn't wait for it to fill, you would have died from lack of water before then if you just sat and waited.

The circumference of a circle is 12.56 cm. What is the area? Use 3.14 for PI
tankabanditka [31]
Hola!

Circumference of circle is 12.56 cm
Means,

2 × π × r = 12.56

r = 12.56 × 3.14 × 2

r = 1.999 cm

According to Question,

Area of Circle:

π × r²

3.14 × 1.99 × 1.99

12.547 cm² = 12.56 cm² (approximately.)

Hence,
Area of Circle is 12.56 cm²

hope it helps!
