Answer:
That number is a rational number.
Find the slope: m=(19.00-13.60)/(2003-1998)=1.08
so we have y=1.08x +b
next, use the point (2003, 19.00) to find b:
19.00=1.08*2003 +b =>b=-2144.24
so the equation is y=1.08x-2144.24

Answer:
143.1 ft
Step-by-step explanation:
Assuming the rope is tied to the boat, and that the geometry can be modeled by a right triangle, the Pythagorean theorem is helpful.
150² = 45² + d²
d = √(150² -45²) = √20475 ≈ 143.1 . . . . feet
The horizontal distance between the man and the boat is about 143.1 feet.
Answer:
W = field width = 48 ft
Step-by-step explanation:
Review: the formula for Perimeter of a rectangle is P = 2W + 2L.
Here we're told that the Perimeter is 168 ft. Therefore:
168 ft = 2L + 2W. But we are also told that W = 36 ft. Then:
168 ft = 2L + 2(36 ft) = 2L + 72 ft.
Subtracting 72 ft from both sides, we get 2L = 96, which tells us that:
L = 48 ft.
The field is 48 ft long.
