Identify which of the twelve basic functions listed below fit the descrịtion given. y=x, y=x^(2),y=x^(3),y=|x|,y=(1)/(x),y=e x, y=\sqrt(x),y=lnx, y=sinx, y=cosx, y=\int (x),y=(1)/(1+e^(-x)) The one function that is decreasing (0,\infty ). a. y=|x| C. y=(1)/(1+e^(-x)) b. y=lnx d. y=(1)/(x)

i think the answer is true

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
