Consider the equation below. X2 + y2 − 2x − 4y − z + 5 = 0 reduce the equation to one of the standard forms. Classify the surfac

jeka57 [31]

we are given

$x^2+y^2-2x-4y-z+5=0$

standard form:

We will complete x , y and z square

make all x , y and z terms together

$x^2-2x+y^2-4y-z+5=0$

$x^2-2x+y^2-4y-z=-5$

$x^2-2*1*x+y^2-2*2*y-z=-5$

$x^2-2*1*x+1^2+y^2-2*2*y+2^2-z=-5+1^2+2^2$

$(x-1)^2+(y-2)^2-z=0$

$z=(x-1)^2+(y-2)^2$

It is an infinite paraboloid

Show work for 1.6 > 1.3

Brrunno [24]

1.6 is let's say one pie and 6/10 of a pie and that's how much a baker made which is obviously more that 1 pie and 3/10 of a pie that the baker made. A process for that is 1.6 =1 6/10 = 16/10 and if u cross multiply that by 1.3 = 1 3/10= 13/10 the value in the 16/10 side will be 160 which is more that the value on the 13/10 side which is 130
