When more offspring than can survive are produced, it is called overproduction. Variation among these offspring exists. The offspring with variations more suited to their environments will be more likely to survive.
Answer:
224
Step-by-step explanation:
We will need the following rules for derivative:
Sum rule.
Constant multiple rule.
Power rule.
Slope of y=x is 1.
by sum rule.
by constant multiple rule.
by power rule.
Now we need to find the derivative function evaluated at x=9.
In case you wanted to use the formal definition of derivative:
Or the formal definition evaluated at x=a:
Let's use that a=9.
We need to find f(9+h) and f(9):
(used foil or the formula (x+a)(x+a)=x^2+2ax+a^2)
Combine like terms:
Ok now back to our definition:
Simplify by doing 1044-1044:
Each term has a factor of h so divide top and bottom by h:
Answer:I think is 18 divided by 6
Step-by-step explanation:
Because they are saying each that is your clue word that means you need to divide.
I hope it helps :)

Answer:
The total cost of 5 pillows and 7 sheets is $205.345
Step-by-step explanation:
Let x be the price of pillow case
We are given that the price of the pillows is 3 times as much as the price of a pillow case
Price of pillow = 3x
Price of 2 pillows = 2(3x)=6x
Price of 3 pillow case = 3x
At a store, 2 pillows and 3 pillow cases together cost $73.08.
So, 6x+3x=73.08
9x=73.08
x=8.12
So, Price of 1 pillow case = 8.12
Price of 1 pillow = 3x=3(8.12)=24.36
Price of 3 pillow =3(24.36)=73.08
Let y be the cost of 1 sheet
The total cost of 3 pillows and 4 sheets is $120.82
So, 73.08+4y=120.82
y=11.935
Price of 1 sheet = 11.935
Price of 7 sheets = 7(11.935)=83.545
Price of 5 pillows =5(24.36)=121.8
So,the total cost of 5 pillows and 7 sheets=83.545+121.8=205.345
Hence the total cost of 5 pillows and 7 sheets is $205.345
