9+7=16 and 5+8=13
Hope i helped, please leave a thanks! Thanks!
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>
Slope is 2/5
Step by step you go up 2 and over 5 to reach the next point
I think 10.2 when I use calculater
