Which of the following have a frequency factor of b = 1?
a sine function whose period is 2pi radians
a sine function whose x-coefficient is 2pi
a cosine function with no phase shift whose x-coefficient is 1
a sine function whose graph shows 2 cycles from - 4pi radians to 0
a sine function whose graph shows 2 cycles from 0 to 2pi radians
a cosine function whose graph shows 4 cycles from 0 to 4pi radians
a cosine function whose graph shows 1 cycle from 3 pi radians to 5 pi radians

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
