PLEASE Answer asap!!!!

Zina [86]

Answer:

x=0

Step-by-step explanation:

The axis of symmetry: $x=\frac{-b}{2a}$ when the equation is $y=ax^2+bx+c$

The given equation is:

$y=x^2-6$

To make the a and b values more easily identifiable, we can rewrite it like this:

$y=1x^2+0-6$

Now, we can tell that a=1 and b=0. Plug these into the equation $x=\frac{-b}{2a}$ :

$x=\frac{-(0)}{2(1)}\\x=0$

Therefore, the equation for the axis of symmetry for the parabola is x=0.

I hope this helps!

Find the radius of a circle having area 616cm square.

OLEGan [10]

Answer:

$\boxed{\sf Radius \ of \ circle = 14 \ cm}$

Given:

Area of circle = 616 cm²

To Find:

Radius of circle

Step-by-step explanation:

$\sf \implies Area \ of \ circle = \pi r^{2} \\ \\ \sf \implies 616 = \frac{22}{7} \times {r}^{2} \\ \\ \sf \implies 616 \times \frac{7}{22} = {r}^{2} \\ \\ \sf \implies 28 \times \cancel{22} \times \frac{7} { \cancel{22}} = {r}^{2} \\ \\ \sf \implies 28 \times 7 = {r}^{2} \\ \\ \sf \implies 196 = {r}^{2} \\ \\ \sf \implies {r}^{2} = 196 \\ \\ \sf \implies r = \sqrt{196} \\ \\ \sf \implies r = \sqrt{ {14}^{2} } \\ \\ \sf \implies r = 14 \: cm$
