Sketch one cycle of the cosine function y= cos 2θ

Based on function transformations, the graph of y= cos(2θ), is the same as the graph of <span>y= cos(θ), with a component B of 2, in which case, it means the period is the only thing that differs

well the period for this function will then be  </span>\bf \cfrac{2\pi }{B}\iff \cfrac{2\pi }{2}\implies \pi

so, the graph of is, the same as y= cos(θ), just shrunk by half horizontally

Which right prism would have the same volume as a square prism with a base area of 36 m2 and a height of 3 m?
Neko [114]
Well to find the volume of the square prism, first you need to multiply the base area (36) by its height (3) and you would end up with 108m3 as the volume. You may not be familiar with this because u are most likely taught length times width times height as volume, but what i just did is the same because length times width is the sum of the base area, and height was already given. Anyways, now that we have gotten the square prism volume (108m3) we need to find which prism has the same volume. I’m gonna save u from searching and tell you that it is the rectangular prism because length times width times height (18x2x3) equaled 108 just like the square prism.

Her horizontal distance to the rim satisfies the ratio
  (10 ft -6 ft)/distance = tan(25°)
so the distance is
  distance = (4 ft)/tan(25°) ≈ 9 ft

Geometry
Mademuasel [1]
DB is a median (given). It goes from vertex point D to midpoint B. 

The point B is the midpoint of segment AC. So B cuts AC into two equal halves: AB and AC
Meaning AB = AC

AC = AB+BC ... segment addition postulate
AC = AB+AB ... substitution; replace BC with AB (valid because AB = AC)
AC = 2*AB
2*AB = AC
2*AB = 50 ... substitution; replace AC with 50
2*AB/2 = 50/2 ... divide both sides by 2
AB = 25 which is the answer
