Answer:

Step-by-step explanation:

From the Pythagorean Theorem

a^2 + b^2 = c^2

a = 1

b = ?

c = 2

1^2 + b^2 = 2^2

1 + b^2 = 4

b^2 = 4 - 1 = 3

b = sqrt(3)

Tan(30) = opposite / adjacent.

adjacent = sqrt(3)

Tan(30) = 1/sqrt(3)

=========

If you need a decimal, it is

1 / 1.321

tan 30 = 0.5774

7. Use the compound-interest formula to find the account balance A with the given conditions, where P=principal, r=interest

Artist 52 [7]

Answer:

Step-by-step explanation:

Finding compound interest :

A = (150,000)(1 + 0.025)⁶
A = (150,000)(1.025)⁶
A = (150,000)(1.15969342)
A = <u>$173,954.01</u>

Two ships leave the same port in different directions, forming a 120° angle between them. One ship travels 70 mi. and the other

kondaur [170]

Answer : Distance between the ships to the nearest miles = 106.03 ≈ 106 mi.

Explanation :

Since we have shown in the figure below :

a=70 mi.

b=52 mi.

c=x mi.

$\text{Since two ships leaves the same port in different directions forming a }120\textdegree\text{angle between them.}$

So, we use the cosine rule , which states that

$c^2=a^2+b^2-2ab.cosC\\\\x^2=70^2+52^2-2\times 70\times 52\times cos(120\textdegree)\\\\x^2=4900+2704-7280\times (-0.5)\\\\x^2=7604+3640\\\\x^2=11244\\\\x=\sqrt{11244}\\\\x=106.03$

So, c = x= 106.03 mi.

Hence, distance between the ships to the nearest miles = 106.03 ≈ 106 mi.
