What are the dimensions of the tabletop with the
DIA [1.3K]

Answer:

Dimensions of the tabletop is 2.8 cm × 2.8 cm.

Step-by-step explanation:

From the picture attached,

ABCD is a tabletop with leaves AEG, BEF, CFH and GDH.

Dimensions of the tabletop ABCD,

Length = AB

Width = BC

Coordinates of A → (1, 3)

Coordinates of B → (3, 5)

Coordinates of C → (5, 3)

Coordinates of D → (3, 1)

Length of segment = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

AB = \sqrt{(3-1)^2+(5-3)^2}

     = \sqrt{4+4}

     = 2\sqrt{2}

     ≈ 2.8 units

BC = \sqrt{(5-3)^2+(3-5)^2}

     = \sqrt{4+4}

     = 2\sqrt{2}

     = 2.8 units

Therefore, dimensions of the tabletop is 2.8 cm × 2.8 cm.

Write the equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8)
nataly862011 [7]

Answer:

y=\frac{x}{0.3}-18 \ or \ 3y=10x-54

is the equation of perpendicular line.

Step-by-step explanation:

We are given , the equation of a line is  y=-0.3x. +6

We can deduce that the slope of the given line is m=-0.3

The slope of its perpendicular line would be , m_p= \frac{-1}{m} =\frac{1}{0.3}

Now using the point slope form, y-y1= m_p(x-x1)

Use the given point (3,-8) \ as\ (x1,y1) substituing these.

y-(-8)= \frac{1}{0.3} (x-3)\\y+8=\frac{x}{0.3} -10\\y=\frac{x}{0.3} -18

Therefore the required equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8) is y=\frac{x}{0.3} -18[/tex]
