Answer:

174 feet below sea level

Step-by-step explanation:

y is the number of minutes so you can multiply 14 by 9

14*9 is 126

then you add 126 to -300

126 + (-300) is essentially 126 - 300 and that is -174

the submarine was at 174 feet below sea level

If x = 5, y = 6, and z= 2, is V x2 + y2 + z2 + 50<br> rational or irrational? Explain.
Bumek [7]

Answer:

irrational

Step-by-step explanation:

because

5² + 6² + 2² + 50 = 25+36+4+50 = 115

and 115 is not a squared integer or rational number, so that sqrt(115) is one of these numbers with infinite digits after the decimal point but without any repeating pattern.

and that is per definition irrational.

Problem 15.2. A nautical mile is a unit of distance frequently used in ocean navigation. It is defined as the length of an arc s
Stels [109]

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
