Question

I have four math courses this semester please help me:

Plane Trigonometry:
Give all the six functions if sec(theta) is 7/5.

Plane Geometry:
Find the Total Area of a cube with 6 cm edge.

Statistic:
Age of workers
57, 44,53,44,45,52,49,48,41,52,55,58,57,51,59,42,39,41,42,45,46,47,47,42,44

Determine the age of workers belong to the 6th decile and interpret.

Modern Geometry:
Given Rectangle FROG with FR=2x+y, RO=x+2, OG=x+12 and FG=y+6. Find the area and perimeter.

Just want to know. I just came from my Pre-final exams. Questions i encounter.

Answer 1

Plane Geometry: Area of one cube = 6*6 = 36 cm^2. There are 6 faces in a cube. The total area is 6*36 = 216 cm^2.

Answer 2

using the picture above: perimeter = sum of all sides....so sum it up. Area of a rectangle is \[A = length * width\]
