A. -1
(1,2) and (2,1)
slope = 2 -1 / 1 -2
slope = 1 / -1
slope = -1
I would say there would be 5 itineraries ie one each for Thailand, Singapore, Hong Kong, Laos and Bali though for the countries Thailand and Laos there may be more than one stop so there would be a minimum of 5 itineraries.
Answer:
a = 1√6
b = -2
Step-by-step explanation:
Hello,
To solve this trigonometric problem, we need to convert this values into fractions
a).
Sin45° = 1/√2
cos30° = √3/2
Sin60° = √3/2
Sin45° / (cos30° + sin60°) = [(1/√2) ÷ (√3/2 + √3/2)]
(1/√2) ÷ (√3/2 + √3/2)
Add √3/2 + √3/2
1/√2 ÷ 2√3/2
1/√2 × 2/2√3
2/2√(2×3)
2/2√6
1/√6
b
Cos 180° = -1
Sin150° = ½
Tan135° = -1
2cos180° - 2sin150° - tan135°
(2 × -1) - (2×½) - (-1)
-2 - 1 + 1 = -2
Answer:
9 hours babysitting
3 hours landscaping
Step-by-step explanation:
Since Maya worked 3 times as many hours in babysitting than landscaping
so landscape hours is x and babysitting is 3x so
3(7)+11=
21+11=32
so each hours she works landscaping and for 3 hours of babysitting she earns $32
96/32=3 so
9 hours babysitting
3 hours landscaping
