What is the axis of symmetry of the parabola y= 1/3 (x-10)^2 - 6

GalinKa [24]

Answer:

The equation of the axis of symmetry is equal to

$x=10$

Step-by-step explanation:

we have

$y=\frac{1}{3}(x-10)^2-6$

This is the equation of a vertical parabola written in vertex form open upward (because the leading coefficient is positive)

The vertex represent a minimum

The axis of symmetry is equal to the x-coordinate of the vertex

we have that

The vertex is the point (10,-6)

The x-coordinate of the vertex is 10

therefore

The equation of the axis of symmetry is equal to

$x=10$

The circumference of a circle is 60 pi cm. What is the radius of the circle?

kykrilka [37]

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=60\pi \end{cases}\implies 60\pi =2\pi r\implies \cfrac{60\pi }{2\pi }=r\implies 30=r$

a certain state the license plate has two digits, then two letters, and then two digits. How many different license plates are p

xxTIMURxx [149]

Step-by-step explanation:

Choosing 4 digits out of 10 = 10C4 = 210.

Arranging the 4 digits in 4 places = 4!

Total number of ways to arrange digits

= 210 * 4! = 5040.

Choosing 2 letters out of 26 = 26C2 = 325

Arranging the 2 letters in 2 places = 2!

Total number of ways to arrange letters

= 325 * 2! = 650.

Total number of possible license plates

= 5040 * 650 = 3,276,000.
