Step-by-step explanation:
noob hahahahahhahahahaha
A horse can run 1 3/8 of a mile in 1 3/5 minute. How long does it take the horse to run 1 mile?
So what i would personally do first is convert the fractions into decimals.
1 3/8= 11/8= 1.375 of a mile
1 3/5= 8/5 =1.6 of a minute
Now we find the rate of change
I
The scale on the map is 1 in = 13.5 units
135/10 = 13.5
Ok so this is conic sectuion
first group x's with x's and y's with y's
then complete the squra with x's and y's
2x^2-8x+2y^2+10y+2=0
2(x^2-4x)+2(y^2+5y)+2=0
take 1/2 of linear coeficient and square
-4/2=-2, (-2)^2=4
5/2=2.5, 2.5^2=6.25
add that and negative inside
2(x^2-4x+4-4)+2(y^2+5y+6.25-6.25)+2=0
factor perfect squares
2((x-2)^2-4)+2((y+2.5)^2-6.25)+2=0
distribute
2(x-2)^2-8+2(y+2.5)^2-12.5+2=0
2(x-2)^2+2(y+2.5)^2-18.5=0
add 18.5 both sides
2(x-2)^2+2(y+2.5)^2=18.5
divide both sides by 2
(x-2)^2+(y+2.5)^2=9.25
that is a circle center (2,-2.5) with radius √9.25
