1 answer:
Licemer1 [7]4 years ago

Answer:

Step-by-step explanation:

Our function is : 3x²-3x-1

  • 3x²-3x+2=2
  • 3x²-3x-1+3=2
  • 3x²-3x-1= -1
  • the number that gives us -1 is 1 (from the graph)

so x is 1

  • 3x²-3x-1= x+1  ⇒3x²-4x-2 = 0
  • Δ(the dicriminant)= (-4)²-4*3*(-2)= 16+24 =40
  • two solution x and y
  • x= (4-√40)/6 and y= (4+√40)/6
  • x= -0.38 and y = 1.7
  • so the estimations are -0.38 and 1.7

Answer:

Area of given figure = 197.48 mi² (Approx.)

Step-by-step explanation:

Note;

Divide given figure into a semi-circle, rectangle, and square

Given:

Radius = 8 mi

Length of rectangle = 11 mi

Width of rectangle = 8 mi

Side of square = 3 mi

Find:

Area of given figure

Computation:

Area of given figure = Area of semi-circle + Area of rectangle + Area of square

Area of given figure = (π/2)(r²) + [L x B] + Side²

Area of given figure = (3.14/2)(8²) + [11 x 8] + 3²

Area of given figure = (1.57)(64) + [88] + 9

Area of given figure = 100.48 + [88] + 9

Area of given figure = 197.48 mi² (Approx.)
