The distance between the friends at the end of one hour can be found from the Pythagorean theorem to be
.. d = √(40^2 +35^2) = √2825 = 5√113 ≈ 53.15 . . . . miles
Since the friends are continuing in the same directions at the same speeds, their distance apart will increase by this amount each hour.
distance = t*5√113 . . . . miles after t hours

540
Step-by-step explanation:
9 times 60 equals 540
Answer:
-140
Step-by-step explanation:
a₀ = 3
a₁ = 3 - 13*1 = -10
a₂ = -10 + 13*2 = 16
a₃ = 16 - 13*4 = -36
a₄ = -36 + 13*8 = 68
<u>a₅</u> = 68 - 13*16 = <u>-140</u>
* a₀=3 n is integers and n ≥ 1
aₙ = aₙ₋₁ + (-1)ⁿ * 13 * (2)ⁿ⁻¹
