Answer:
The equation of the line normal to the curve of y=cos1/3x, where x=pi is y= 2√3 x - 10.38
Step-by-step explanation:
The equation of the normal to the curve is
Y- y1 = - 1/m (x- x1)
Where m is the gradient.

Answer:
21,600
Step-by-step explanation:
minutes in a day: 1,440
1,440 x 15 = 21,600
We know: The sum of the angles of each quadrilateral is 360°.
Therefore we have equation:
x + 3x + 4x + 2x = 360
10x = 360 |:10
x = 36
