Evaluate the integral by interpreting it in terms of areas. In other words, draw a picture of the region the integral represents, and find the area using geometry. [0,1] |9x-3|

2.5

Step-by-step explanation:

The integral of a function is the area under the curve.

Graph |9x−3|.  The result is two lines.  The areas under these lines are triangles.  The first triangle has a base of ⅓, and a height of 3.  The second triangle has a base of ⅔, and a height of 6.

The total area is therefore:

A = ½ (⅓) (3) + ½ (⅔) (6)

A = ½ + 2

A = 2.5

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

∞ this is your sign
