What is the area of the figure? How do you find it?

The area of a square is just side times side. So 3 * 3 = 9. 

There are 4 half-circles which is the same as 2 full circles. Area of a circle is pi * the radius squared or A =  \pi  r^{2}.

So we do 2(pi * (1.5)²) >> 2(2.25pi) = 4.5pi.

Now we add our two areas together. So the area of the whole thing is represented by the equation 4.5pi + 9. Plug this into a calculator to get your accurate measurement. 

4.5pi + 9 ≈ 23.137 m²

2x+y=-2. x+y=5. the x coordinate of the solution to the system shown is
lara31 [8.8K]
We have y = -2 - 2x ;
Then, x + ( -2 - 2x ) = 5 ;
x - 2 - 2x = 5;
- x - 2 = 5 ;
-x = 7 ;
x = - 7;
Finally, y = - 2  - 2 × ( - 7 ) ;
y = - 2 + 14 ;
y = 12;
<span>The x coordinate of the solution to the system is - 7 .</span>

If f(y) = 2y - 2/5,<br> what is f(f^-1(1024))?
SCORPION-xisa [38]

Answer:

-0.399

Step-by-step explanation:

f^-1(1024)=(2*1024-2/5)^-1= 0.000488

f(0.000488)=2*0.000488-2/5= -0.399

Find the slope of the line that goes through the given points.<br> (0,8) and (- 4,0)
Ronch [10]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (- 4, 0)

m = \frac{0-8}{-4-0} = \frac{-8}{-4} = 2

Step-by-step explanation:

From the above question

1 liter = $143.54

12.4 liters = $x

Cross Multiple

1 liter × $x = 12.4 liters × $143.54

$x = 12.4 liters × $143.54/1 liter

$x = $1779.896

Therefore, the total cost for Stacy gas in dollars and cents is $1779.896
