Step-by-step explanation:

The number of litres / year = 5.67811 * 10^5 * 3.15576 * 16^7

= 17.91875241 * 10^12

= 1.791875241* 10^13 or 1.791875241e13.

The linear regression model gives mathematical relationship between two variables, the dependent and independent variables. The linear models between the quantity sold and the variables average price, disposable income and monthly advertising are :

y = - 4713.46x + 117763
y = 2.94x - 58384
y = - 1.75x - 32655

To create a linear model using the data given, we use technology such as a excel or a linear regression calculator :

The linear model created using a linear regression calculator between each of the independent variables and quantity sold are :

Average price of deep - dish and Quantity sold :

Average price of deep - dish pizza(X)
Quantity sold (Y)

y = - 4713.46x + 117763

Disposable income and Quantity sold :

Disposable income (X)
Quantity sold (Y)

y = 2.94x - 58384

Monthly advertising expenditure and Quantity sold :

Monthly advertising cost (X)
Quantity sold (Y)

y = - 1.75x - 32655

Select the polynomial that is a perfect square trinomial. 36x2 − 4x 16 16x2 − 8x 36 25x2 9x 4 4x2 20x 25.

Naya [18.7K]

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

The given polynomial is

$a) 36x^2-4x+16$

What is the form of perfect square polynomial?

$(ax+b)^2$

we solve this method by using perfect square method

add and subtract 1/9

$36x^2-4x+16+\frac{1}{9}-\frac{1}{9}$

factor 36

$\frac{143}{9}+36(x^2-\frac{x}{9}+\frac{1}{324} )$

Now complete the square

$\frac{143}{9}+36(x^2-\frac{1}{18})^2$

Therefore this is not perfect square trinomial.

Similarly for

$b) 16x^2-8x+36$

Complete square is,

$16(x-\frac{1}{4})^2+35$

This polynomial is also not perfect square trinomial.

$c) 25x^2+9x+4\\$

complete square is,

$25(x+\frac{9}{50})^2+\frac{319}{100}$

This polynomial is not perfect square trinomial.

$d)4x^2+20x+25\\$

complete square is,

$(2x+5)^2$

This polynomial is perfect square trinomial.

Therefore,

The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.

Please answer correctly !!!!! Will mark brainliest !!!!!!!!!!!!

Answer:

Up by 3 units, right by 9 units.

Step-by-step explanation:

The subtraction in (x-9)^2 makes the function shift to the right, adding would make it shift left! Adding numbers to the equation would make the function go up, and subtracting would make it go down. Hope this helps :)
