7 0

Answer:

≈ 62.8

Step-by-step explanation:

Using the equal ratios of

\frac{areaof circle}{areaofsector} = \frac{circleangle}{sectorangle}, that is

\frac{100\pi }{sector} = \frac{2\pi }{\frac{2\pi }{5} } = 5, thus

5 × sector = 100π ( divide both sides by 5 )

sector = 20π = 20 × 3.14 = 62.8 units²

7. The points P(2, -3), Q(3, -2) and R(8, z) are
Hatshy [7]

Answer:

z = 3

Step-by-step explanation:

Since the points are collinear then the slopes between the points are equal.

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = P (2, - 3) and (x₂, y₂ ) = Q (3, - 2)

m = \frac{-2+3}{3-2} = 1

Repeat with

(x₁, y₁ ) = Q (3, - 2) and (x₂, y₂ ) = R (8, z )

m = \frac{z+2}{8-3} = \frac{z+2}{5} , then

\frac{z+2}{5} = 1 ( multiply both sides by 5 )

z + 2 = 5 ( subtract 2 from both sides )

z = 3

Please help with both if you can!<br><br> Thank you!
Alexxandr [17]

Answer:

15). is done

16).

slope =  \frac{ {y}^{1} -  {y}^{o}  }{ {x}^{1}  -  {x}^{o} }  \\  =  \frac{2 - ( - 2)}{ - 3 - 9}  \\  =  \frac{4}{ - 12}  \\ slope =  -  \frac{1}{3}
