Part 1: Similarities of sine and cosine graphs are that both has an amplitude of 1 and a period of 2pi.
A differences between sin and cos graphs includes that sin graph passes through point (0, 0).
The required cosine graph is <span>f(x) = 3 cos(4x - 3π/2) + 4</span>
Answer: The girls walked 
miles.
Step-by-step explanation:
Given: Distance from home to school = 
mile
Distance from school to store = 
mile
Distance from store to home =

= 
= 
= 
miles
Hence, The girls walked miles.
I don't think I understand what you mean, but I will guess. A quadrilateral must have 4 sides to it and have 4 vertices (corners).
it's wrong because he put a closed circle on the nine when he was supposed to put an open circle because nine is not less than itself but the thing that he did right wad that he went to the left if it was a greater than or equal symbol then it would be correct
hope this helps
