Mathematics
1 answer:
vivado [14]3 years ago
7 0

Answer:

A ≈ 9.0 ft²

Step-by-step explanation:

70° = 7π/18 radians

Area of the arc section

A = ½(7π/18)8² = 12⁴/₉π ft² = 39.09537 ft²

As the triangle is isosceles, the other two angles are (180 - 70) / 2 = 55°

law of sines 8 / sin55 = L / sin 70  L = 9.17722

so the triangle height  = √(8² - (9.17722/2)²) = 6.55321

Area of triangle ½(6.55321)(9.17722) = 30.07016

Area = 39.09537 - 30.07016 = 9.025211 ≈ 9.0 ft²

What is the graph for the above relationship?
Vesna [10]

Second graph.

<h2>Explanation:</h2>

Hello! You haven't provided any relationship, but I found it on the internet and it is the table attached below. The point-slope form of the equation of a line is given by:

y=mx+b

So:

y-Intercept: \\ \\ (0,b) \\ \\ \\ From \ the \ table: \\ \\ (0,b)=(0,46) \\ \\ So: \\ \\ b=46

Finding the slope:

m=\frac{39-46}{1-0} \\ \\ m=-7

So the equation of the line is:

y=-7x+46

From the graphs, only option 2 and 4 have negative slope and only option 2 passes through (0,46)

Conclusion: Correct option is second graph.
