The correct answer is index

The index depicts which root is meant. Thus, for example, if we mean the cube root of some number, say x, it is shown as \sqrt[3]{x}. Likewise, fourth root of x is shown as \sqrt[4]{x}. So on and so forth this continues. The only exception to this rule is the square root, wherein, by convention, we do not write the index and still it is understood that it is the second root that is meant.

Thus, the correct answer is "index".

Therefore, The <u>index</u> of a radical expression is the number indicating which root (square root, cube root, etc.) is meant.

Find an equation equivalent to r = 10sin ø in rectangular coordinates.
kherson [118]

Answer: x^2 + y^2 -10y = 0

Step-by-step explanation:

Cartesian coordinates, also called the Rectangular coordinates, isdefined in terms of x and y. So, for the problem θ has to be eliminated or converted using basic foundations that are described by the unit circle and the right triangle trigonometry.

r= 10sin(θ)

Remember that:

x= r × cos(θ)

y= r × sin(θ)

r^2= x^2 + y^2

Multiply both sides of the equation by r. This will give:

r × r = 10r × sin(θ)

r^2 = 10r × sin(θ)

x^2 + y^2= 10r × sin(θ)

Because y= r × sin(θ), we can make a substitution. This will be:

x^2 + y^2= 10y

x^2 + y^2 -10y = 0

The above equation is the Rectangular coordinate equivalent to the given equation.

Given; D is the Midpoint of CE / Prove DE =1/2CE
aleksley [76]

Answer:

Check explanation

Step-by-step explanation:

Here, we want to make a prove;

Mathematically , since D is the midpoint of CE

Then;

CE = CD + DE

Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE

I.e CD = DE

Hence, we can express CE as follows;

CE = DE + DE

CE = 2 DE

Divide both sides by 2

CE/2 = DE

Hence; DE = 1/2 CE
