so... notice the picture below, the angle in the fourth quadrant
now... notice, the cosine is just the distance the angle makes with the x-axis
so... using the pythagorean theorem, get the opposite side, from that triangle, keeping in mind that, "y" is negative in the 4th quadrant
once you get "y", get any other trigonometry value you need :)
2.44346x is 140 80 is 1.39626 5x is is an incomplete math problem
Answer:
is the better unit price.
Step-by-step explanation:
120 is the better unit price because if you divide 120 divided by 6 you get 20 and if you divide 200 divided by 8 you get 25 so then you would pick the cheapest one because of its price and amount.
The simplest radical form is 
Explanation:
The expression is 
To determine the radical form, let us write the number 68 as a product of prime factors.
Thus, we have,
Since, 2, 17 are prime factors and hence, no further factorization is possible.
Hence, it can be written as,
Applying the radical rule 
, we have,
Simplifying, we have,
Thus, the simplest radical form is
