A. 2.

A radical is an expression which implies the use of a root.

There are three components of a radical expression:

(i) The root "√".

(ii) The radicand √"a".

(iii) The degree or index of the radical \sqrt["n"]{a}, when index of the radical is not shown then it understood to be a index of 2.

The index is the number used to indicate the degree of the root.

For the example \sqrt{10}, 10 is the radican and the index is not shown so it understood is 2.

Write the equation in standard form of a circle with center (-7,2), tangent to the y-axis.
Vesna [10]

Answer:

(x+7)^2+(y-2)^2=7^2

Step-by-step explanation:

Tangent to y-axis means that the side of the circle TOUCHES the y axis.

Since the center is at (-7,2) and it touches the y axis, we can figure out the radius. It goes from (-7,2) to y-axis. Horizontally, the center is 7 units left of y-axis, so that is the radius -----  7 units

The standard form of a circle is:

(x-h)^2+(y-k)^2=r^2

Where

(h,k) is the center

r is the radius

Putting the information into the form, we have:

(x-h)^2+(y-k)^2=r^2\\(x-(-7))^2+(y-(2))^2=7^2\\(x+7)^2+(y-2)^2=7^2

THis is the standard form.
