Answer:

The graph has only one x-intercept

Step-by-step explanation:

we have

$f(x)=-4x^2+12x-9$

we know that

The discriminant of a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$D=b^{2}-4ac$

in this problem we have

$f(x)=-4x^2+12x-9$

$a=-4\\b=12\\c=-9$

substitute

$D=12^{2}-4(-4)(-9)$

$D=144-144$

$D=0$

The discriminant is zero

That means ----> The quadratic equation has one real solution

The graph has only one x-intercept

Answer:

24501.42 cubic meters

Step-by-step explanation:

Volume of a cylinder

= pi r^2 h

Given diameter = 34

radius r = diameter/2

= 34/2 = 17

So radius r = 17

Height h = 27

Pi = 3.14

Volume = 3.14 x (17)^2 x 27

= 3.14 x 17 x17 x 27

Multiply through

= 24501.42 cubic meters
