Part 1 8.19 meters
11 * .305 = 3.355
8 * .305 = 2.44
3.354 + 2.44 = 8.19
it will cost $252 to cover it
you need 9 square meters to cover 8.19 meters of area
so 9 * 28 = 252
Answer:
D
Step-by-step explanation:
The bracket means that it is inclusive so since the questions says that it has to be greater than or equal to, we can cross out B and C.
A means that it is all number less than or equal to -22 so it has to be D

Answer:
x = pi n
Step-by-step explanation:
6 sec^2(x) − 6 = 0
Add 6 to each side
6 sec^2(x) − 6+6 = 0+6
6 sec^2(x)=6
Divide by 6
sec^2(x) = 1
Take the square root of each side
sqrt( sec^2(x) ) = ±sqrt(1)
sec(x) =± 1
sec (x) = 1 sec(x) = -1
Take the inverse sec of each side
sec^-1(sec (x)) = sec^-1(1) sec^-1(sec (x)) = sec^-1(-1)
x = 2 pi n x = pi + 2 pi n where n is an integer
Combining
x = pi n
