Kamila [148]

Answer:

Step-by-step explanation:

Area of circle = 56 cm²

                   πr² = 56

                 3.14r² = 56

                         r²=56/3.14

                        r²= 17.83

                        r = √17.83

                        r = 4.22 cm

The diameter of the circle  = diagonal of the square

Diagonal of the square = 2 * 4.22 = 8.44 cm

x² + x² = 8.44²

2x² = 71.2336

  x² = 71.2336/2

  x² = 35.6168

x = 5.967 cm

Their running paths form the legs of an isosceles right triangle. The hypotenuse of such a triangle (the distance between Steve and Scott) is √2 times the length of one leg. Each has run 10 miles in the hour since they split.

They are running at 10 miles per hour.

Find the slope between the<br> following points:<br> (-1,19) and (11,16)
patriot [66]

Answer:

Slope =-1/4

Step-by-step explanation:

y=mx+n

Slope=m=(y2-y1)/(x2-x1)

A(-1,19).... x1 =-1, y1=19

B(11,16)..... x2=11, y2=16

Slope=(16-19)/(11-(-1))=(-3)/(11+1)=-3/12=-1/4
