Answer:

153.9 in^2

Step-by-step explanation:

We know that the formula for the area of a circle is:

$A=\pi r^{2}$

Finding the radius (half the diameter):

$14/2=7$

Then substitute and solve:

$A=\pi (7)^{2}$

$A=153.93804$

$A$ ≈ $153.9$ in^2

Polynomial Equation question<br>(Screenshot included)

Illusion [34]

$y = {x}^{3} - 4 {x}^{2} - 45x \\ y = x( {x}^{2} - 4x - 45) \\ y = x(x + 5)(x - 9) \\ x = 0, - 5,9$
So, to find our x-intercepts, y must be zero
$0 = x \\ \\ 0 = (x + 5) \\ - 5 = x \\ \\ 0 = (x - 9) \\ 9 = x$
ANSWER: (0,0) (-5.0) (9,0) are your x-intercepts

Use the zero product property to find the solutions to the equation x2 – 15x – 100 = 0.

IrinaK [193]

Answer:

x= 20 x =-5

Step-by-step explanation:

x^2 – 15x – 100 = 0.

What two numbers multiply to -100 and add to -15

-20 * 5 = -100

-20 +5 = -15

(x-20) (x+5) =0
