Step-by-step explanation:

DEFINITION: Besting: the clockwise totation (0° to 360°) from North to any line.

A) Calculate the bearings of D from A:

bearings of D from A =x

looking the picture:

x=48°+55°+180°

x+103°+180°

x=283°

B)Calculate the bearings of A from C:

bearings of A from C =y

180°+55°=y

y=235°

C) Calculate the distance between A and B:

The angle in B is 74° (Because 55°+51°+74°=180°)

Using the Law of sines:

\frac{19}{sin(74)} =\frac{AB}{sin(51)} \\\\AB=19sin(51)sin(74)\\AB=14,2\\\\

D)Calculate the distance between D and C:

Using the Law of cossines:

DC^{2} =27^{2} +19^{2} -2*27*19*cos(48)\\DC=20,09

E) A Helicopter is hovering at A at a height of 2.5Km, find angle of elevation of helicopter from C:

The triangle HBA is rectangle

\alpha =arctan(\frac{2,5}{19})

α=7,49°

Suppose you take out a loan for $9,000, at 12% ordinary interest. If the amount of interest is $762.00, what is the time period?
Ierofanga [76]

Answer:

answer is option c

Step-by-step explanation:

Amount = $9,000

interest rate (r) = 12%

interest = $762.00

time = ?

we know,

I = \dfrac{PRT}{100}

762  = \dfrac {9000\times 12\times T}{100}

t = 0.7056 years

t = 0.7056 × 365 days

t = 257.54 days  ≅ 258 days

correct answer is option c.
