Step-by-step explanation:
12. The first attachment has the rate of change on each interval. (It is listed at the end of the interval.) It is computed by dividing the difference in length by the corresponding difference in months. The units of rate of change are inches per month.
The baby was growing fastest in the first 3 months.

13. The first attachment has the rate of change on each interval. It is computed by dividing the difference in height by the corresponding difference in seconds. The units of rate of change are meters per second. A negative number indicates the elevator is going down.
The second attachment shows a graph of the distance versus time.

I find it convenient to let a spreadsheet do repetitive calculations. I can enter the formula once and copy it where needed. I don't have to worry about the accuracy of the arithmetic, and the result can be formatted to suit the problem requirements. (The basics of most spreadsheet programs can be learned in a few minutes.)

Katie wants to collect over 100 seashells. She already has 34 seashells in her collection. Each day, she finds 12 more seashells on the beach. Katie can use fractions of days to find seashells.
Write an inequality to determine the number of days, d, it will take Katie to collect over 100 seashells
<em><u>Answer:</u></em>
Kathie needs more than 5 days to get over 100 shells
The required inequality is
<em><u>Solution:</u></em>
Given that,
Katie wants to collect over 100 seashells.
She already has 34 seashells in her collection.
Each day, she finds 12 more seashells on the beach
Let "d" be the number of days she takes to cover 100 sea shells
From given statement,
She finds 12 seashells each day
Then for "d" days, the number of sea shells she collected is 12d
She already had = 34
So, the equation can be framed as:
Here we used "greater than" symbol, since she wants to collect over 100 seashells
Solve the inequality
This means she won't have more than 100 shells until the 6th day
Thus she needs more than 5 days to get over 100 shells
