Combine the radicals. 3√5-8√5+2√5
weeeeeb [17]

Answer:  -3\sqrt{5}

-3 times the square root of 5

=============================================

Explanation:

Let x = \sqrt{5}

Replace all the root 5 terms with x and we go from

3\sqrt{5}-8\sqrt{5}+2\sqrt{5}

to

3x-8x+2x

From here, combine like terms to get

3x-8x+2x = -5x+2x = -3x

and the last thing to do is replace the x with sqrt(5)

-3x = -3\sqrt{5}

Meaning that,

3x-8x+2x = -3x

3\sqrt{5}-8\sqrt{5}+2\sqrt{5} = -3\sqrt{5}

Snap company issues 10% five year bonds on january 1 of this year, with a par value of 120,000 and semiannual interest payments
mezya [45]

Answer:

<h3>$189,292.92</h3>

Step-by-step explanation:

Using the compound interest formula to get the equivalent amount after 5 years;

A = P(1+r/n)^nt

P is the principal = 120,000

r is the rate = 10% = 0.1

t is the time = 5 years

n is the time of compounding = 1/2  = 0.5(semi annual interest)

Substitute into the formula;

A = 120,000(1+0.1/0.5)^(5)(0.5)

A = 120,000(1+0.2)^2.5

A = 120,000(1.2)^2.5

A = 120,000(1.5774)

A =  189,292.92

Hence the company issue is $189,292.92
