Answer:

The vector joining the ship to the rock is t= 7 i + 5 j

The direction is 0.9505 radians east of north.

Step-by-step explanation:

The position vector of the ship:

r= 1 i + 0 j

The position vector of the ship:

s= 6 i + 5 j

The vector joining the ship to the rock is:

t = r + s

t = (1 i + 0 j) + (6 i + 5 j)

t = 7 i + 5 j

The bearing of the rock to the ship is:

Θ= \frac{ \pi}{2} - arctan (\frac{5}{7})= 0.9505 radians

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.
