Answer:
a) 6080 ft
b) 29.952 mph = 30 mph to 2s.f
c) 15.6 knots
Step-by-step explanation:
Length of an arc is given as (θ/360) × (2πr)
For a nautical mile, θ = 1' = (1/60)° = 0.01667°
Length of a nautical mile = (0.01667/360) × (2π × 3960) = 1.152 miles
1 mile = 5280 ft
1.152 miles = 5280×1.152 = 6082.1 ft = 6080 ft to the nearest 10 feet.
b) 1 knot = 1 nautical mile/hour
1 nautical mile/hour = 1.152 miles/hour (from part (a))
1 knot = 1.152 miles/hour
26 knots = 26 × 1.152 miles/hour = 29.952 mph = 30 mph to 2 s.f
c) 1.152 mph = 1 knot
18 mph = (18×1/1.152) knots = 15.625 knots

Answer:
<em>x² + 4y²+ 2x - 24y + 33 = 0
</em>
<em />
<em>= (x+1)² + 4(y-3)² - 1 - 36 + 33 = 0
</em>
<em>= (x+1)² + 4(y-3)² = 4</em>
<em />
<em>= (x + 1)²/2² + (y - 3)²/1² = 1</em>
<em></em>
<em>This is an Ellipse: C(-1,3)</em>
<em>The Standard Form of an Equation of an Ellipse is : </em><em>(x - h)²/a²/ (y - k)²/b² = 1</em>
<em></em>
<em>where Pt(h,k) is the center. </em><em>(a variable positioned to correspond with major axis)</em>
<em>a and b are the respective vertices distances from center</em>
<em>and√a² - b²are the foci distances from center: a > b</em>
Answer:
2 2/3
Step-by-step explanation:
You can simplify 2 4/6 into 2 2/3, this means that you can now subtract the two numbers.
