Answer:

area of the figure: 29.92 m²

formula's:

  • area of rectangle: length * width
  • area of sector: ∅/360 * πr²

solving steps:

area of rectangle + area of sector

5.5 * 4 + 30/360 * π(5.5)²

22 + 7.919

29.92 m²

Answer:

Calculate the area of the sector and the area of the rectangle separately, then add them together to determine the area of the composite figure.

<u>Rectangle</u>

Area of a rectangle = width × length

                                = 4 × 5.5

                                = 22 m²

<u>Sector</u>

<u />\textsf{area of sector}=\dfrac{\theta\pi r^2}{360} \textsf{ (when } \theta \textsf{ is measured in degrees)}

                     =\dfrac{30 \cdot\pi\cdot5.5^2}{360}

                     =\dfrac{121}{48}\pi  \textsf{ m}^2

<u>Total area</u>

total area = area of rectangle + area of sector

                =22 +\dfrac{121}{48}\pi

                = 29.91943148...

                = 29.9 m² (nearest tenth)

Answer:

5.2

Step-by-step explanation:

To find the height of the plant after 7 weeks, we need to find out the equation of the line of best fit and plug in 7 for x. We already have our y - intercept, which is 1,  and we have a point on the x axis for which the y coordinate is an integer, (5, 4). Since we already have the y - intercept of +1 we have y = mx + 1. Since this applies to (5,4) we can plug this in to our equation. This is then 4 = 5m + 1. Subtracting 1 from both sides, we get 3 = 5m. Dividing by 5, we receive m = 3/5. Since now we have our slope, we can plug in 7 and find out our answer. Plugging in 7 we receive, y = 3/5 * 7 + 1, which is equal to y = 4.2 + 1. This means that y = 5.2, so 5.2 is our answer.

Answer:

(B) 3n - 11

Step-by-step explanation:

(2n + 5) - (3n + 7) + (4n - 9) = 2n + 5 - 3n - 7 +4n - 9 = 3n  - 11
