Priyanka and Ethan were asked to find an explicit formula for the sequence -3,-14,-25,-36,...−3,−14,−25,−36,.. .minus, 3, comma, minus, 14, comma, minus, 25, comma, minus, 36, comma, point, point, point Priyanka said the formula is g(n)=-3-11ng(n)=−3−11ng, left parenthesis, n, right parenthesis, equals, minus, 3, minus, 11, n. Ethan said the formula is g(n)=-3+11ng(n)=−3+11ng, left parenthesis, n, right parenthesis, equals, minus, 3, plus, 11, n. Which one of them is right?

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

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
