Choose whether the expression is a result of multiplying

Art [367]

The given expression is a result of squaring binomials

<h3>Factoring quadratics </h3>

From the question, we are to determine whether the given expression is a result of multiplying conjugates together, squaring binomials, or neither

The given expression is

9z² +54z +81

To do this,

First, we will factor the expression

Factoring the expression

9z² + 54z + 81

First, factor out 9

9(z² +6z +9)

9(z² + 3z + 3z + 9)

9[z(z + 3) + 3(z + 3)]

9[(z +3)(z +3)]

9[(z +3)²]

This can further be expressed as

3²[(z +3)²]

[3(z +3)]²

(3z +9)²

Hence, the expression is a result of squaring binomials

rehistoric cave paintings were discovered in a cave in France. The paint contained 34 % of the original carbon-14. Use the expo

Paladinen [302]

Answer:

Therefore the age of paint is 8915.78 years.

Step-by-step explanation:

Given that, the paint contain 34 % of the original carbon-14.

The exponential decay model for carbon-14 is

$A=A_0e^{-0.000121t}$

A= Remaining amount of carbon.

$A_0$ = initial amount of carbon.

Here A= 34% of $A_0$ $=\frac{34}{100}A_0$

$\therefore \frac{34}{100}A_0=A_0e^{-0.000121t}$

$\Rightarrow \frac{34}{100}=e^{-0.000121t}$

Taking ln both sides

$\Rightarrow ln|\frac{34}{100}|=ln|e^{-0.000121t}|$

$\Rightarrow ln|\frac{34}{100}|={-0.000121t$

$\Rightarrow t=\frac{ln|\frac{34}{100}|}{-0.000121}$

$\Rightarrow t= 8915.78$

Therefore the age of paint is 8915.78 years.

Marigold Industries collected $104,000 from customers in 2019. Of the amount collected, $24,400 was for services performed in 20

m_a_m_a [10]

Answer:

$\text{Net accrual income}=\$31,600$

Step-by-step explanation:

We have been given that Marigold Industries collected $104,000 from customers in 2019. Of the amount collected, $24,400 was for services performed in 2018. In addition, Marigold performed services worth $39,000 in 2019, which will not be collected until 2020.

Let us find revenue earned in 2019 by subtracting revenue earned from 2018 and adding revenue earned in 2019 to total revenue as:

$\text{Revenue in 2019}=\$104,000-\$24,400+\$39,000$

$\text{Revenue in 2019}=\$118,600$

Marigold Industries also paid $73,900 for expenses in 2019. Of the amount paid, $29,100 was for expenses incurred on account in 2018. In addition, Marigold incurred $42,200 of expenses in 2019, which will not be paid until 2020.

Now, we will find expenses in 2019 by subtracting expenses in 2018 and adding expenses in 2019 to total expenses as:

$\text{Expenses in 2019}=\$73,900-\$29,100+\$42,200$

$\text{Expenses in 2019}=\$87,000$

To find accrual net-income, we will subtract$87,000 from $118,600 as:

$\text{Net accrual income}=\$118,600-\$87,000$

$\text{Net accrual income}=\$31,600$

Therefore, the net accrual income for 2019 would be $31,600.
