Answer:
3z-44
Step-by-step explanation:
All you have to do is to simplify the numbers. 2 + 6 - 52 = -44.
Answer:
x = 180
Step-by-step explanation:
First, you need to know
1. Double-angle formula:
cos(2x) = 
2. Pythagorean identity:

Back to your problem, replacing the variable by the above:

By Double-angle formula
By Pythagorean identity
Given 



, we know -1 < sinx < 1, for every x ∈ R



True the answer is true babes :)
Using the relation between velocity, distance and time, it is found that t = 3 hours.
<h3>What is the
relation between velocity, distance and time?</h3>
Velocity is <u>distance divided by time</u>, hence:

For this problem, the parameters are given as follows:
d = 15 miles, v = 5 mph
Hence the time in hours is found as follows:


5t = 15
t = 15/5
t = 3 hours.
