Answer:

45/28

Step-by-step explanation:

Hey There!

They want us to find the tangent of R

Remember in sohcahTOA

t - tangent

o - opposite

a - adjacent

meaning that

tan = \frac{opposite}{adjacent}

The opposite of angle r is 45

the adjacent of angle r is 28

so tanR=\frac{45}{28}

Computer towers purchased for $30900 depreciates at a constant rate of 12.6% per year. Write the function that models the value
Paha777 [63]

Answer: the computer towers will be worth $10521 after 8 years

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

A = P(1 - r)^t

Where

A represents the value of the computer towers after t years.

t represents the number of years.

P represents the initial value of the computer towers.

r represents rate of decay.

From the information given,

P = $30900

r = 12.6% = 12.6/100 = 0.126

Therefore, the function that models the value of the computer towers after (t)years from now is

A = 30900(1 - 0.126)^t

A = 30900(0.874)^t

Therefore, when t = 8 years, then

A = 30900(0.874)^8

A = $10521

The rectangle below has an area of x^2-6x-7 square meters and a width of x-7 meters
Illusion [34]

<em><u>Complete Question:</u></em>

The rectangle below has an area of x^2-6x-7 square meters and a width of x-7 meters. What expression represents the length of the rectangle?

<em><u>Answer:</u></em>

<h3>The expression represents the length of the rectangle is (x + 1) meter</h3>

<em><u>Solution:</u></em>

Given that,

\text{Area of rectangle} = x^2 - 6x - 7 \\\\Width = x - 7

<em><u>TO FIND: LENGTH = ?</u></em>

We know that,

Area\ of\ rectangle = length \times width \\\\Therefore\\\\x^2 - 6x - 7 = length \times x - 7\\\\length = \frac{x^2 - 6x - 7 }{x - 7 }\\\\length = \frac{(x-7)(x + 1)}{x - 7}\\\\\text{cancel out x-7 from numerator and denominator} \\\\length = x + 1

Thus expression represents the length of the rectangle is (x + 1) meter
