What is the general equation of a cosine function with an amplitude of 3, a period of 4x, and a horizontal shift of
?
© y = 4500S(3(x-1))
y-3cos(4=(x+))
y=3cos(0.5(x+5))
y=4COS(0.2(x+ ))

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

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
