Answer:

8.54 units (3s.f.)

Step-by-step explanation:

Distance between 2 points

=   \sqrt{(y1 - y2)^{2}  +  {(x1 - x2)}^{2} }

Identify the coordinates of the 2 endpoints of the line:

(-5, 5) and (-2, -3)

Using the distance formula above,

length of line segment

=  \sqrt{[5 - ( - 3)]^{2}  + [ - 5 - ( - 2)]^{2} }  \\  =  \sqrt{ {(5 + 3)}^{2}  + ( -5 + 2)^{2} }  \\  =  \sqrt{ {8}^{2} +  {( - 3)}^{2}  } \\  =  \sqrt{73}  \\  = 8.54 \: units \: (3 \: s.f.)

ddd [48]
The circumference of a circle is 2\pi r and it coresponds to a 360 degree angle.

The circumference of the circle is 2*4*pi=8pi m=25.12m

25.12m......360 degrees
10 m.........x degrees
x=10*360/25.12=143.31 degrees

The coordinates of the vertices if triangle ABC are A (1,-1) , B (1,4) , and C (8,4). What is the length in units of the line se
kaheart [24]

Length of the line segment is 5 units.

Step-by-step explanation:

  • Step 1: Length of the line segment that connects A and B is the distance between the points A (1, -1) and B(1, 4). x1 = 1, x2 = 1, y1 = -1, y2 = 4
  • Step 2: Calculate the distance using distance formula √(x2 - x1)² + (y2 - y1)²

⇒ Length = √(1 - 1)² + (4 - -1)² = √5² = 5 units

A local club is arranging a charter flight to hawaii. the cost of the trip is $574 each for 81 passengers, with a refund of $5 p
Sunny_sXe [5.5K]
Let x be the number of passengers.
The discounted cost is given by,

Cost = 574-5(x-81) = 574-5x + 405 = 979 -5x

Total revenue, R(x) = x(979 - 5x) = 979x - 5x^2

At maximum revenue, dR/dx = 0 => dR/dx = 979 - 10x = 0 =>10x = 979 => x =979/10 = 97.9 ≈ 98 passengers

Therefore,
Revenues, R(97) = 98[574 -5(98-81)] = 98[574-85] = $47,922
