To solve this problem you must apply the proccedure shown below:
1. You want to express Cos(7π<span>/3) as a trigonometric function of an angle in Quadrant I. Therefore, you have:
2. You can find the coterminal angle of </span>7π/3 by substract 2π, as following:
=7π/3-2π
=π/3
3. Then, you have:
Cos(7π/3)
Cos(π/3)
The answer is: Cos(π/3)
Answer:
260
Step-by-step explanation:
5×20=100
So 13 × 20
because 5 percent of the collection is 13 so it is 260.
Answer:
see explanation
Step-by-step explanation:
to determine which of the ordered pairs are on the line, substitute the coordinates of the point into the left side of the equation and if the value obtained equals the right side then it lies on the line.
(, - )
2 + 7 = 9 ⇒ correct
(- 5, - 6 )
- 15 + 24 = 9 ⇒ correct
(1, - )
3 + 6 = 9 ⇒ correct
(- 1, 3 )
- 3 - 12 = - 15 ⇒ incorrect
The 3 ordered pairs
( , - ), (- 5, - 6), (1, - )
All line on the line 3x - 4y = 9
Answer:
Use a graph calculator
Step-by-step explanation:
Because 0.1 is 10% or 1/10 of 100.
