Answer:
ok? I'm guessing what equal to it?
Step-by-step explanation:
ex: (8,4) (12,6)
anything they multiply with the same multiplying number.
Such as 4 x 5 you would also need to do the same to 2, 2 x 5 your line would be at (20,10)
Answer:
4.5 months a
Step-by-step explanation:
9 babies are five months old
Average age = 5 months
12 babies are seven months old.
Average age = 7 months
Currently the average age of the babies are: 5months + 7months = 12 months
21 babies = 12 months
How many full months from now will the average age of the 21 babies first surpass 20 months old
Surpassing 20 months old means above 20, = 21 months
5months + x + 7 month + x = 21months
Collect like terms
12 months + 2 x = 21 months
2x = 21 months - 12 months
2x = 9 months
2x = 9 months/2
x = 4.5 months
Outlier - Distant from the rest.
(1,9) and (10,7) are outliers.
Answer - 2

Hey there mate ;)
Note that the quadratic function
A(x) = x(100-2x) gives the area.
Now, this equation is equivalent to:
A(x) = 100x - 2x²
To find maximum value of A, we first find the derivative of the given function:
Now find the critical value by setting dA/dx=0, that is:-
Solving for x, we get:
Hence, the critical point is x=25
Now, Find 2nd derivative to check if the equation has maximum value:
Noting that the 2nd derivative is negative, hence, we have a maximum value. Infact, the maximum value in this case is when the value of x = 25.
The maximum area is therefore,
→ The Correct answer is:
