Answer:

86°

Step-by-step explanation:

This is a circle theorem question, specifically the cyclic quadrilateral theorem.

If you have a a 4-sided shape that touches the circumference of the circle with all 4 vertices, it's know as a cyclic quadrilateral.

The theorem states: "Opposite angles in a cyclic quadrilateral add up to 180°"

We want the angle at point L so we subtract the opposite angle to L (Angle J, which is 94°), so 180 - 94 = 86

The neat thing is that it's still a quadrilateral, and if you find all the remaining sides, they should add up to 360°, just like a regular square or rectangle.

PLZ HELP!! Which real numbers are zeroes of the function?
astra-53 [7]

The correct answers are: 1/2, 2 and -2.


To get this, factor f(x)

f(x)=2x^3-x^2-8x+4

f(x)= (2x^3-x^2) - (8x -4)

f(x)= (2x-1)(x^2) + (2x-1)(-4)

f(x)= (2x-1)(x^2-4)

f(x)= (2x-1)(x-2)(x+2)


2x-1=0

2x=1

x=1/2


x-2=0

x=2


x+2=0

x=-2
