The third term in an arithmetic sequence is 9 and the fifth term is 21 . If the first term if a1, which is an equation for the n
tino4ka555 [31]

Answer:

A: an = 6n - 9

Step-by-step explanation:

third term in an arithmetic sequence is 9

a3 = a + 2d

a + 2d = 9

the fifth term is 21

a5 = a + 4d

a + 4d = 21

a + 2d = 9 (1)

a + 4d = 21 (2)

Subtract (1) from (2) to eliminate a

4d - 2d = 21 - 9

2d = 12

d = 12/2

d = 6

Substitute d = 6 into (1)

a + 2d = 9 (1)

a + 2(6) = 9

a + 12 = 9

a = 9 - 12

a = -3

nth term of this sequence = a + (n - 1)d

= -3 + (n - 1)6

= -3 + 6n - 6

= 6n - 9

an = 6n - 9

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
