Answer: \sqrt{2^4} \cdot \sqrt{5}


Explanation:

\sqrt{80} = \sqrt{2 \times 2 \times 2 \times 2 \times 5} = \sqrt{2^4 \times 5} = \sqrt{2^4} \times \sqrt{5} = \sqrt{2^4} \cdot \sqrt{5}

60 pts!!! HELP Find the inverse of the function f(x)= 4/9 x-4<br> show work
earnstyle [38]

Answer:

Inverse Function: f^-1(x) = 9/4x + 9

Step-by-step explanation:

To find  the inverse function we can interchange the position of the variables x and y, and then solve for y;

y = 4/9x - 4 => x = 4/9y - 4,

x = 4/9y - 4,

4/9y = x + 4,

y = 9/4x + 9/4(4),

y = 9/4x + 9/ f^-1(x) = 9/4x + 9

2. Write an expression to represent f (20)
Furkat [3]

Answer:

I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).

Step-by-step explanation:

So, my answer was f(20) = 64(1/2)^19

f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.

Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19

I hope this helps!

Straight line depreciation applies the same amount of depreciation in each year.
Our Depreciation Base is 21,000 - 1,000 = 20,000
The useful life is 5 years, so each year we depreciate 20,000 ÷ 5 = 4,000

Book Value is Cost - Accumulated Depreciation
After Year 1: 
Book Value = 21,000 - 4,000 = 17,000

Answer is A) 17,000
