As x increases and y stays constant, z as y increases and x stays constant, zas x increases and z stays constant, y

Consider

(1) As x increases and y stays constant, z ______

(2) As y increases and x stays constant, z _____

(3) As x increases and z stays constant, y ______

(1) As x increases and y stays constant, z increases

When y stays constant, z is directly proportional to x. So , as x increases the z also increases.

(2 ) As y increases and x stays constant, z decreases.

When x stays constant, z is inversely proportional to y. So , as y increases the z decreases.

(3) As x increases and z stays constant, y increases

(z stays constant)

So equation becomes

When z stays constant, y is directly proportional to x. So , as x increases the y also increases.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
