30 pts ! The height of the Ferris wheel in feet can be represented by the function 50 cos (π/15(x-10))+52 with time in x seconds
Dahasolnce [82]

h = 50 cos ( pie(x - 10 )/15 ) + 52

80 = 50 cos ( pie( x - 10 )/15 ) + 52

80 - 52 = 50 cos ( pie( x - 10 )/15 )

28 = 50 cos ( pie( x - 10 )/15 )

cos ( pie( x - 10 )/15 ) = 28/50

cos ( pie( x - 10 )/15 ) = 56/100

cos ( pie( x - 10 )/15 ) = cos ( 56 )

cos ( pie( x - 10 )/15 ) = cos ( 0.3111 pie )

Thus ;

pie( x - 10 )/15 = 0.3111 pie

( x - 10 )/15 = 0.3111

x - 10 = 15 × 0.3111

x - 10 = 4.6665

x = 10 + 4.6665

x = 14.6665 [ approximately ]

Thus the correct answer is exactly what u chose goodjob .....

Which is the graph of linear inequality 6x+2y>-10
NemiM [27]
For this case we have the following inequality:
 6x + 2y\ \textgreater \  -10

 The first thing we must do is to graph the linear function:
 6x + 2y = -10

 Then, we must evaluate ordered pairs in the following way:
 (x, y)
 The ordered pairs that meet the inequality, will be included as part of the graph.
 Therefore, the shaded region contains all the ordered pairs that meet the inequality.
 Answer:
 See attached image.

The spray from a spinning lawn sprinkler covers an area of 625pi square feet.
kari74 [83]
<span>x/900(pi) = 135/360

x = [900pi][135/360] = 337.5(pi) sq ft (area that receives water)
Hope this helps!
