If you want to make it so that you work most of the hours on the first 4 days, you should work 5 hours. 5*4=20, so 1 hour would be left over on the 5th day.
Answer:
Step-by-step explanation:
<u>The first time:</u>
- 16 m up and 16 m down = 32 m
The second time and each time after, half of the previous distance
<u>This is a GP with the first 6 terms:</u>
<u>Sum of the distances:</u>
- 32 + 16 + 8 + 4 + 2 + 1 = 63 m
<span>the main formula is (a - b)² = a² -2ab + b²
</span><span>as for 49x^2 – 56x + 16, it is the same of (7x -4)²
so the </span>the factored form of 49x^2 – 56x + 16 = (7x -4)(7x -4)
Distance = speed X time
distance in heavy traffic = 40mph X 1hour = 40miles
distance in light traffic = 60mph X 3hours = 180miles
Total distance = 180 + 40 = 220miles
