Mathematics

Answer:

slope = -2

Step-by-step explanation:

Slope formula: \frac{y2-y1}{x2-x1}

Given points:

(3 -4) = (x1, y1)

(-2, 6) = (x2, y2)

To find the slope, input the given points into the slope formula:

\frac{6-(-4)}{-2-3}

Solve:

6 - (-4) = 6 + 4 = 10

-2 -3 = -5

Simplify:

\frac{10}{-5}=\frac{2}{-1}=-2

The slope is -2.

son4ous [18]

Answer:

75.44 Square Inches

Step-by-step explanation:

The diagram of the problem is produced and attached.

To determine the area of the cleaned sector:

Let the radius of the larger sector be R

Let the radius of the smaller sector be r

Area of the larger sector =\frac{\theta}{360}X\pi R^2

Area of the smaller sector =\frac{\theta}{360}X\pi r^2

Area of shaded part =Area of the larger sector-Area of the smaller sector

=\frac{\theta}{360}X\pi R^2-\frac{\theta}{360}X\pi r^2\\=\frac{\theta \pi}{360}X (R^2- r^2)

From the diagram, R=10 Inch, r=10-7=3 Inch, \theta=95^\circ

Therefore, Area of the sector cleaned

=\frac{95 \pi}{360}X (10^2- 3^2)\\=75.44$ Square Inches
