The number A of tablet computers sold (in millions) can be modeled by the function A=4.5t2+43.5t+17 , where t represents the num
Rina8888 [55]
The problem indicates that A represents the number of tablet computers sold in millions. So, if 65 million were sold, we must substitute A = 65 to the equation. Then, we find for t.

65 = 4.5t² +43.5t + 17
Solving for t using a calculator,
t = 1 and -10.67

Let's take the positive root. So, t=1.
That means the year would be 1 year after 2010. <em>Therefore, the answer is 2011.</em>

Henry knows that the circumference of a circle is 18mc006-1.jpg inches. What is the area of the circle?
lesantik [10]
The complete question is:
Henry knows that the circumference of a circle is 18π inches. What is the area of the circle?

Solution:
Circumference (C) of the circle can be written as:

C=2 \pi r \\ \\ 18 \pi =2 \pi r \\ \\ r=9

Using this value of radius, we can find the Area(A) of the circle.

A= \pi  r^{2}  \\  \\ &#10;A= \pi (9)^{2}  \\  \\ &#10;A=81 \pi

Therefore, area of the circle having a circumference of 18π inches will be 81π inches²

It costs a publishing company $0.55 to print one copy of a certain novel. This company paid $725,000 for the rights to the novel
Dmitrij [34]

Answer:

The correct answer is b. 116,900

The publishing company must sell 116,900 copies of the book to break even.

Step-by-step explanation:

Each book costs 0.55 to make and the company can sell it at 6.75, which means that the company earns 6.20 from each book, this is called the net value. If you divide the amount htat the company paid for the rights by the net value you can find the total number of copies that the company has to sell to break even.  

# books = $725,000/$6.20 = 116935 or approximately 116900 copies of the book.
