Please help me provide an explanation too!

Step-by-step explanation:

The shaded area is the area of the rectangle minus the area of the two circles.

The circles have a diameter of 10.5cm.

The area of each circle is

A=(pi d^2)/4

So the total area of the two circles is

A=(pi d^2)/2

So the shaded area is

A=10.5(21)-(pi (10.5^2)/2

A=220.5-55.125*pi cm^2

A=47.32 cm^2 (rounded to nearest hundredth of a square centimeter)

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
