Mathematics

Answer:

\sqrt{ {28x}^{2} - 6x }

Step-by-step explanation:

You would substitute "2x" for every "x" in the function in the same way you would substitute any other number.

So if f(x)=Sqrt[7x²-3x], then: f(2x)=Sqrt[7(2x)²-3(2x)]

=Sqrt[7(4x²)-3(2x)]

=Sqrt[28x²-6x]

Which of the following segments is a radius of OK?<br> ОА. АМТ<br> ОВ. Вт<br> Ос. AMR<br> O D. KM
FrozenT [24]

Answer:

A) TA

Step-by-step explanation:

A radius goes from the center of a circle to the outside edge.  

RP connects two points on the outside edge of the circle without going through the center.  This is not a radius.

TR connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

GP connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

TA connects the center of the circle to the outside edge.  This is a radius.
