Answer:

Step-by-step explanation:

1) Sin² Ф = 1 - cos² Ф

So, 1 - Sin² Ф = 1 - (1 - cos² Ф)

= 1 - 1 + cos² Ф = cos² Ф

2) tan x = Sin x /Cos x

tan x * csc x = Sin x /Cos x * 1/Sin x = Sinx * 1 / cos x * sin x

=1/cos x = Sec x

Playland park charges 7 dollars admission plus 75 crnts per ride. Funland park charges 12.50$ admission plus 50 cents per ride.

WINSTONCH [101]

Answer:

22 rides

Step-by-step explanation:

Both the parks has a fixed cost (admission fee) and a variable cost (per ride cost). We can model 2 equations in "x" [let x be number of rides], equate them and find "x".

<u>Playland Park:</u>

Fixed Cost = 7

Variable Cost = 0.75x (in dollars)

Equation = 7 + 0.75x

<u>Funland Park:</u>

Fixed Cost = 12.50

Variable Cost = 0.50x (in dollars)

Equation = 12.50 + 0.50x

Now we equate and solve for x:

$7+0.75x=12.50 + 0.50x\\0.75x-0.50x=12.50-7\\0.25x=5.50\\x=\frac{5.50}{0.25}\\x=22$

Hence,

the cost would be same for both parks for 22 rides
