Find the distance between the points (0, 0) and (6, -8). 4 √28 10
kvasek [131]

Answer:

10

Step-by-step explanation:

The formula for finding the distance between 2 points (x1, y1) and (x2, y2) is

d = √[(x2 - x1)² + (y2 - y1)²]

Here (x2, y2) = (6, -8)  and (x1, y1) = (0, 0)

Plugging them gives us

d = √[(6 - 0)² + (-8 - 0)²]

     d = √[(6)² + (-8)²]

        d = √[36 + 64]

           d = √100

               d = 10

Find the linear equation in slope intercept form that passes through the points (5,3) and (2,-1)
padilas [110]

\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{3})\qquad  (\stackrel{x_2}{2}~,~\stackrel{y_2}{-1}) \\\\\\ slope =  m\implies  \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-3}{2-5}\implies \cfrac{-4}{-3}\implies \cfrac{4}{3} \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-3=\cfrac{4}{3}(x-5)\implies y-3=\cfrac{4}{3}x-\cfrac{20}{3} \\\\\\ y=\cfrac{4}{3}x-\cfrac{20}{3}+3\implies y=\cfrac{4}{3}x-\cfrac{11}{3}

This for composite figures
Vinil7 [7]

Answer:

  114 square meters

Step-by-step explanation:

The figure decomposes into two congruent trapezoids, each with bases 15 m and 4 m, and height 6 m. The area formula for a trapezoid is ...

  A = 1/2(b1 +b2)h

__

Each trapezoid will have an area of ...

  A = 1/2(15 +4)(6) = 57 . . . . square meters

The figure's area is twice that, so is ...

  figure area = 2 × 57 m² = 114 m²
