Answer:
f(x) = + cosx or - cosx
Step-by-step explanation:
(2+tan^2x/sec^2x) -1 =(f(x))^2
=(( 1 + sec^2x)/sec^2x) -1
= 1 / sec^2x + 1 - 1
= 1 / sec^2x
= cos^2x
(f(x))^2 = cos^2x
f(x) = + cosx or - cosx
The probability of it being greater than one on a six sided die is 5/6 or 5:6
Since the photo booth charges a $500 fee for two hours at the party and an additional 50 dollars per hour, we have:
50x+500=C
Where x is the hours stayed and C is the total cost. Since Cindy doesn't want to spend more than 700 dollars, we have:

So she spent an additional 4 hours on the rental.
Okay, Do you know how to find the surface area?
Rectangle (left): A = 9 x 7 = 63
Rectangle (right): A = 2 x 10 = 20
Quarter circle: A = (1/4 x 3.14 x 3^2) = 7.065
A = 63 + 20 + 70.65
A = 90.065 square feet
Hope this helps! :)
