We have the following function:
p (x) = - 2 (x-9) ^ 2 +200
We derive to find the maximum of the function:
p '(x) = - 4 (x-9)
Rewriting:
p '(x) = - 4x + 36
We match zero:
-4x + 36 = 0
We clear x
x = 36/4
x = 9 degrees
The maximum population occurs when x = 9.
We evaluate the function for this value:
p (9) = - 2 * (9-9) ^ 2 +200
p (9) = 200
Answer:
The maximum number of fish is:
p (9) = 200
Answer:
<h3>The option D) All of the above is correct</h3><h3>The major disadvantage of crude rates is that:</h3>
- They may not allow for comparison of populations that differ
- They do not permit comparisons of populations that vary in age distribution.
- They are difficult to calculate from available data sources.
Hence options A ,B and C are correct
Step-by-step explanation:
Given that crude rate
To find the disadvantage of crude rate :
A crude rate is the number of new cases (or deaths) occurring in a specified 
, it can be expressed as the number of cases per 100,000 population at risk.
<h3>The major disadvantage of crude rates is that:</h3>
- They may not allow for comparison of populations that differ
- They do not permit comparisons of populations that vary in age distribution.
- They are difficult to calculate from available data sources.
Hence options A ,B and C are correct
<h3>∴ The option D) All of the above is correct.</h3>
Answer:
If you're looking for a shortcut, I usually find the number 1 less than what you are multiplying 9 by, this case 8, and then add a number that gets to 9.
So 9x6 would be:
5+4=9
54
Step-by-step explanation:
When multiplying by 9s the product's two numbers added together =9.
Sorry if this is confusing. Hope this helps though.
In this article, professor Hillary Farber talks about 'finding balance' in the use of drones by this she means that we need to find a way that we can use drones and have privacy and be safe. I believe that FAA is working to find a balance because they created new rules for the use of drones. Also, they created a national drone registry or list.
Answer:
$48.30
Step-by-step explanation:
If the dinner was $42.00 and they wanted to give a 15% tip, then to find that start by multiplying 42 by 0.15
42.00 x 0.15 = 6.3
now add $6.30 to $42.00
42 + 6.3 = 48.3
