Answer:
in this 3 is the correct answer
Answer:
The magnitude of the vertical component of vector u is
The magnitude of the horizontal component of vector u is
Step-by-step explanation:
A vector quantity has, a magnitude and a direction
The horizontal component of vector is ║u║ cos α
The vertical component of vector is ║u║ sin α
∵ The magnitude of vector u is 12 ft
∵ The measure of angle α is 135°
- Substitute the magnitude and the angle in the rule of
each component
∴ = 12 cos(135)
∴ = 12 sin(135)
∵ cos(135) =
∴ = 12 ( )
∴ =
- The magnitude of a number means the number without its sign
∴ The magnitude of the horizontal component of vector u is
∵ sin(135) =
∴ = 12 ( )
∴ =
∴ The magnitude of the vertical component of vector u is
The table is usually the shape of a rectangle. The area is equal to the length times the width. To make sure, let's recalculate the solution.
Area = length × width
Area = 103.50 cm × 73.75 cm
Area = <span>7,633.125 cm</span>²
So, we established that the answer is correct. Now, I'll introduce the concept of significant figures. There are rules regarding significant figures to be applied conventionally in measurements and calculations. This is to increase precision of the data. Significant figures are digits that carry meaning. When you are given data with a specific number of significant figures, the final answer should also contain the same number of significant figures. In convention, the rule says that the zero's after non-zero digits after the decimal point are significant. Also, all non-zero digits are significant. The value 103.50 has 5 significant figures, and 73.75 has 4. When it comes to multiplication, the answer should contain the least significant figures. So, we should have 4 significant figures. Therefore, the final answer to be reported should be 7,633 cm².
Answer:
33 shirts
Step-by-step explanation:
100% of 20 = 20
65% of 20 = 13
total = 33
Most of the new but cheaper sailboats I see that can be used out at sea usually cost 40-50k, but a pre-owned one would probably be 20-25k depending on the quality of the boat. Plus the price would depend on where you live.
