A textile company bought a piece of weaving equipment for $60,000. It is expected to depreciate at an average rate of 10% per year. a. Write an equation for the value of the piece of equipment Z after

Answers

Answer:

z = 60000(0.9)^t

Step-by-step explanation:

What's good?The equation for the price of the item over time can be written as:

z = 60000(0.9)^t

Here's what each part of the equation means:

- "z" represents the price of the item.

- The initial cost of the item is $60,000, so we start with 60000.

- The item falls at a rate of 10% per year, so we multiply the initial cost by 0.9 each year.

- "t" represents the number of years.

For example, if you want to find the price after 3 years, you would substitute t = 3 into the equation and solve for z:

z = 60000(0.9)^3

z = 60000(0.729)

z ≈ 43,740

So after 3 years, the price of the item would be approximately $43,740. Remember 3 years is just an example. Don't forget to make me the brainliest!!!

Final answer:

The equation for the value of the weaving equipment after 'n' years can be written as Z = 60000(1 - 0.10)ⁿ. For example, if you want to find the value of the equipment after 5 years, substitute n = 5 into the equation and solve for Z, which would be approximately $36,486.

Explanation:

The equation for the value of the weaving equipment after n years can be written as Z = 60000(1 - 0.10)n, where Z represents the value of the equipment and n represents the number of years.

For example, if you want to find the value of the equipment after 5 years, you would substituten = 5 into the equation: Z = 60000(1 - 0.10)5 and solve for Z.

After substituting and calculating, you would find that the value of the equipment after 5 years is approximately $36,486.

A carpenter added a diagonal brace to gate. The gate is 8ft. Wide and 10 ft. Tall. How long is the brace

Answers

Answer:

The brace is $2√(41)$ ft ≅ 12.806 ft long

Step-by-step explanation:

The length of the diagonal of a rectangle can be found using this rule

$d=\sqrt{l^(2)+w^(2)}$ , where

l is its length

w is its width

∵ The gate has shaped a rectangle

∵ Its length = 10 ft

∵ Its width = 8 ft

∴ l = 10 and w = 8

∵ The brace is the diagonal

→ By using the rule above

∴ $d=\sqrt{(10)^(2)+(8)^(2)}=√(100+64)=√(164)$

∴ The length of the brace = $2√(41)$ ≅ 12.806 ft

∴ The brace is $2√(41)$ ≅12.806 ft long
