Substitute the values for a, b, and c into b2 – 4ac to determine the discriminant. Which quadratic equations will have two real

adoni [48]

Step-by-step explanation

<h3>Prerequisites:</h3>

$b^2 - 4ac = 0 \Rightarrow 1 solution$

$b^2 - 4ac > 0 \Rightarrow 2 solutions$

$b^2 - 4ac < 0 \Rightarrow No\ real\ solutions$

----------------------------------------------------------------

$2x^2-7x-9 = 0$

$b^2 - 4ac$

$-7^2 - 4(2)(-9) = 121$

2 Solutions

---------------------------------------------------------------

$x^2-4x+4 = 0$

$b^2 - 4ac$

$-4^2 - 4(1)(4) = 0$

1 Solution

---------------------------------------------------------------

$4x^2-3x-1 = 0$

$b^2 - 4ac$

$-3^2 - 4(4)(-1) = 25$

2 Solutions

---------------------------------------------------------------

$x^2-2x-8 = 0$

$b^2 - 4ac$

$-2^2 - 4(1)(-8) = 36$

2 Solutions

---------------------------------------------------------------

$3x^2+5x+3 = 0$

$b^2 - 4ac$

$5^2 - 4(3)(3) = -11$

No Solutions

Find the area of a circle with the diameter of 3 centimeters. Use 3.14 for pi

Ket [755]

The equation for the area of circle is:
$A = \pi r^{2}$
where r = radius.

The radius of a circle is 1/2 its diameter. Since you know the diameter is 3cm, its radius must be 3cm/2 = 1.5cm.

Now just plug r=1.5 into the equation for the area of the circle to find the area:
$A = \pi r^{2}$
$A = \pi (1.5)^{2}$
$A = 7.07 cm^{2}$
