Number of lawn mowing = x.
His cost per lawn for fertilizer = $6.
His cost per lawn for labor = $14.
Total cost per lawn for fertilizer and per lawn for labor for him = 6+14 = $20.
He charges = $25 per lawn.
So, profit per lawn = 25 - 20 = $5.
Therefore, for mowing x number lawn could be represented by polynomial that represents his weekly profit.
<h3>a) P(x) = 5x.</h3>
b) For mowing 40 lawns per week total profit would be
P(40) = 5(40) = $200.
c) Number of weeks an year = 52.
Therefore,
<h3>Annual profit is 52 * 200 = $10400.</h3>
The statements that are true about this study are:
- This study uses random sampling.
-
This study uses a control group.
-
This study uses a repeated measures design.
Random sampling occurs when each sample has an equal probability of being chosen in a study.
This is seen in the random selection of 100 children. The Control group was used with the first group that had no screen time.
The repeated measures design was also used when multiple measurements were taken during different weeks.

The graph of g(x) would look the same as the given graph, EXCEPT that it'd be compressed by a factor of 1/3. Try graphing both f(x) and g(x) on your calculator and then comparing the 2 graphs.
Answer:
About 2614 years.
Step-by-step explanation:
We are given k, and the information that N/N0 = 0.77, so the C-14 function becomes:
and we can solve for t:
The estimated age of the bird skeleton is 2614 years.
