This is very simple. So you use two formulas:
Rectangle: Length • Width
Semicircle: Area =
With that, you do 0.8 ÷ 2 = 0.4 because we will be using radius. When solved, you get 0.2512... But for this problem, I will be rounding everything to the nearest hundredths.
Area of semicircle: ≈ 0.25
Now we solve for the rectangle. That is very easy. Just multiply 0.75 • 0.8 and you get 0.6
For this problem, I'm not sure why they make you round to the nearest centimeter, but if you do, you get 1 cm. Otherwise,
Round to nearest tenth: 0.9
Round to nearest hundredths: 0.85
Answer:
The vector that describes their hike from their starting position to their final destination is .
Step-by-step explanation:
In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:
(i) <em>A group of hikers walks 3 miles east and then 1 mile north:</em>
(ii) <em>After taking a break, they then hike 4 miles east to their final destination:</em>
The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:
(1)
The vector that describes their hike from their starting position to their final destination is .
