         cos(6x) = 0
cos⁻¹[cos(6x)] = cos⁻¹(0)
                 6x = 90
                  6      6
                    x = 15°
                    x = ¹/₁₂π radians

         cos(6x) = 0
<span>cos⁻¹[cos(6x)] = cos⁻¹(0)
</span>                 6x = 270
                  6       6
                    x = 45
                    x = ¹/₄π radians

         cos(6x) = 0
<span>cos⁻¹[cos(6x)] = cos⁻¹(0)
</span>                 6x = 450
                  6       6
                    x = 75
                    x = ⁵/₁₂π radians

Side AB of square ABCD is parallel to the Y axis and the perimeter of ABCD is 36. If the coordinates of point B is (5,17) . What
Zarrin [17]
<h3>Answer: (C) (14,8)</h3>

============================================

Explanation:

The perimeter of the square is 36, so each side length is 36/4 = 9 units.

Point B is located at (5,17). We move down 9 units to get to (5,8), which is the location of point A. Then we move 9 units to the right to arrive at (14,8) which is point D's location.

Or we could go from B = (5,17) to C = (14,17) and then to D = (14,8). Each time we move 9 units.

A horseback riding trail is 1 mi 40.8 ft long. How long is the trail in yards, feet, and inches?
ch4aika [34]

Answer:  1773.6 yards   5320.8 feet  64324.8 inches

Step-by-step explanation:  

1 mile in yards = 1760                                                                                         40.8 feet in yards = 13.6      1760 + 13.6 =<u> 1773.6 yards </u>

1 mile in feet = 5280 + 40.8 = <u> 5320.8 feet </u>

1 mile in inches  = 63360

40.8 feet in inches = 964.8

63360 + 964.8 = <u>64324.8 inches </u>

<u>hope this helps :) </u>

3500ca = 1fp
MAXImum [283]

Answer: 1fp = 525 minutes

           35fp = 18,375 minutes

<u>Step-by-step explanation:</u>

Solve this using conversions

\dfrac{30\ minutes}{200\ ca } \times \dfrac{3500\ ca}{1\ fp}= 525\ minutes\ per\ fp

For 35 fp, multiply 35 fp by 525 minutes per 1 fp = 18,375

Which are examples of unit rates?
morpeh [17]
Answers: Choice A and Choice C

Saying "$45 per ticket" is the same as saying "$45 for every single ticket" or "one ticket costs $45"

Similarly, "30 seats for every row" is equivalent to "each row has 30 seats"

-------------

choices B and D aren't unit rates because the second value mentioned isn't 1. You would have to divide to get to a unit rate. 
choice B: 5/3 = 1.67 so there are roughly 1.67 shows every week
choice D: 100/5 = 20 meaning its $20 per ticket
