today a boat valued at $45,000.Thebvalue is expected to decrease at a rate of 8.5% each year.What is the value of the boat expec

Stels [109]

Current value of the boat = $45000

Rate at which the value decrease = 8.5%

Value decreased after 1 year = $\frac{8.5}{100}\times45000=3825$

Hence, value becomes = $45000-3825=41175$

Value decreased after 2nd year =

$\frac{8.5}{100}\times41175=3499.875$

Hence, value becomes = $41175-3499.875=37675.125$

Value decreased after 3 year =

$\frac{8.5}{100}\times37675.125=3202.385$

Hence, value becomes = $37675.125-3202.385=34472.74$

So, value of the boat after 3 years becomes $34472.74

Suppose a triangle has 2 sides of length 3 and 4 and that the angle between these two sides is 60 degrees. what is the length of

shusha [124]

Answer:

$\boxed{b.\:\:\:\sqrt{13}}$

Step-by-step explanation:

Let the third side of the triangle be $h\: units$ .

We can apply the cosine rule to find $h$ .

$h^2=3^2+4^2-2(3)(4)\cos(60\degree)$

We evaluate to obtain;

$\Rightarrow h^2=9+16-24(\frac{1}{2})$

$\Rightarrow h^2=25-12$

$\Rightarrow h^2=13$

We take the positive square root of both sides to obtain;

$\Rightarrow h=\sqrt{13}$

The correct answer is B.
