Which graph represents y=³√x ?
QveST [7]

Answer:

1 / (3 - √x³)

Step-by-step explanation:

∛x = x^1/3

^1/3 means the exponent is 1/3

then the derivative is:

d/dx ∛x = d/dx x~1/3 = 1/3*x~(1/3 - 1) = 1/3 x~-2/3 = 1/3 * (1/√x³)

= 1 / (3*√x³)

Hope it helps.

In a circle, chords ST and RA intersect at Y such that SY is perpendicular to RY. The value of mSA + mRT is: a. 90º b. 180º c. 2
pshichka [43]

Answer:

a. 90º

Explanation:

The chords ST and RA intesect at Y, so that SY is now perpendicular to RY and they form an angle 90 degrees at that point. However angles mSA and mRT are both at the circumference of the circle(a chord is a line from point of a circle's circumference to the other) and are both 90 degrees because angle at the circumference is half of angle at the centre in same arc.
