Answer:
Step-by-step explanation:
For a function f to have a maximum as per derivative rule we have to have
f'(x) =0, f"(x) <0
If second derivative =0 also then it is not maximum but point of inflections
Whenever f(x) = ax^n
we have
f'(x) = 0 gives x=0 and
f"(x) = n(n-1) ax ^(n-2)
So for n greater than or equal to there cannot be any maximum
And also for a straight line
y =-4x
y'=-4 and y"-0
No maximum
So only maximum can be for a funciton of the form y = ax^2
Here we do not have that all degrees are either 1 or greater than 1.
So no maximum for any funciton.
Step-by-step explanation:
We need to solve each equation.
a. 6c = 30
c = 30/6 = 5
b.
2d-6=12
Adding 6 both sides
2d-6+6=12+6
2d = 18
d = 9
c.

d.
50=14+3m
50-14=3m
36=3m
m = 12
Hence, this is the required solution.
4p-5p+30 just multiply everything in the brackets by what's not
Answer:
1885
Step-by-step explanation:
A score of 1884 is just below the top 10%. To be in the top 10%, the score must be 1885 or higher.
A suitable calculator or spreadsheet is about the easiest way to figure this.
