Find the distance AB. Give your answers correct to 1 decimal place

Answers

Answer:

AB= 8.1

AB=7.8

Step-by-step explanation:

[tex]ab = \sqrt{ {(8 - 1)}^{2} + {(6 - 2)}^{2} } [/tex]

[tex] = \sqrt{ {7}^{2} + {4}^{2} } = \sqrt{49 + 16} [/tex]

[tex] = \sqrt{65} = 8.1[/tex]

[tex]ab = \sqrt{ {(6 - 1)}^{2} + {(2 - 8)}^{2} } [/tex]

[tex]= \sqrt{ {5}^{2} + { ( - 6)}^{2} } = \sqrt{25 + 36} [/tex]

[tex] = \sqrt{61} = 7.8[/tex]

5. Consider the image below of a pasture at McDonald's Farm.
750 ft
45°
Part A: If McDonald wants to fence in the square pasture and barbed-wire
fencing costs $1.15 per foot, then determine the cost to fence in
the pasture.
Part B: If McDonald wants to cover the square pasture in fertilizer, then he
needs to determine the area of the pasture. What is the area of
the pasture to the nearest hundredth?

Answers

Answer:

Step-by-step explanation:

The area of the square pasture is given by the leg length of the right

triangle which is the same as the side length of the square.

Correct responses:

Part A: $2,439.5Part B: 281, 250 ft.²Method by which the above responses are obtained

Part A

The given triangular side is a right triangle.

Length of the hypotenuse and an acute angle of the right triangle are;

750 ft. and 45°

Therefore;

Leg length of the right triangle = Side length of the square

Leg length of the right triangle = 750 ft. × sin(45°) = 375·√2 ft.

Side length of the square pasture, s = 375·√2 ft.

Perimeter of the fence = 4 × 375·√2 ft. = 1500·√2 ft.

Cost per foot for fencing = $1.15

The cost to fence the square pasture = $1.15/ft. × 1,500·√2 ft. ≈ $2,439.5

Part B:

The area, A, of the square pasture is given by A = s²

Which gives;

A = (375·√2)² = 281,250

The area of the square pasture is A = 281,250 ft.²

Answers

for graphing make sure to shade the right portion and to make the line dotted like (— — — —)
the red is y>8x-4, the blue is y>-1/2x+1/2

2x-.25y < 1 is equal to 2x-1/4y < 1
multiply each side by 4:
8x-y < 4
add y to each side:
8x < 4+y
subtract 4 from each side:
8x-4 < y
rewrite:
y > 8x-4

4x+8y > 4
divide both sides by 8:
1/2x+y > 1/2
subtract -1/2x from each side:
y > -1/2x + 1/2
