Answer:

6.76 m^2

Step-by-step explanation:

Large circle area = pi r^2 = pi L^2 = 60.84

then L = sqrt (60.84/pi)

Small circle radius = r = 1/3 L

small circle area = pi r^2

= pi ( 1/3 sqrt (60.84/pi))^2 = 6.76 m^2

(x-1)(x-3)(x+5)(x+7)=297

mihalych1998 [28]

First simplify the expression into polynomial form,

$(x-1)(x-3)(x+5)(x+7)=297$

$x^4+8x^3-10x^2-104x+105=297$

$x^4+8x^3-10x^2-104x-192=0$

Now factor into,

$(x-4)(x+8)(x^2+4x+6)=0$

Which means the solutions are,

$x-4=0\implies\boxed{x_1=4}$

$x+8=0\implies\boxed{x_2=-8}$

and then two complex solutions because determinant of the third factor $D\lt0$ ,

$x^2+4x+6=0$

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

$(x+2)^2=-2\implies\boxed{x_3=i\sqrt{2}-2},\boxed{x_4=-i\sqrt{2}-2}$

Hope this helps :)

Given the system of inequalities:

Crazy boy [7]

Answer:

$4x-5y$ slope intercept form is option 3 - $y>\frac{4x}{5}-\frac{1}{5}$

$\frac{1}{2}y-x$ slope intercept form is option 4 - $y$

Step-by-step explanation:

Given : The system of inequalities $4x-5y$ and $\frac{1}{2}y-x$

To find : Which shows the given inequalities in slope-intercept form?

Solution :

The slope intercept form is $y=mx+b$ where m is the slope and b is y-intercept.

First inequality is $4x-5y$

Now we take y to one side by subtracting 4x both side,

$-5y$

Divide both side by 5,

$-y$

Multiply both side by -1,

$y>-\frac{1-4x}{5}$

$y>\frac{4x-1}{5}$

$y>\frac{4x}{5}-\frac{1}{5}$

So, Option 3 is correct.

Second inequality is $\frac{1}{2}y-x$

Now we take y to one side by adding x both side,

$\frac{1}{2}y$

Multiply both side by 2,

$y$

So, Option 4 is correct.
