Answer with Step-by-step explanation:
We are given that a function f(x) is continuous on (
).
1.f'(-1)=0 and f''(-1)=-7
We have to find information about f.
When f'(-1)=0 and f''(-1)=-7 < 0
Then, function is maximum at x=-1.
Therefore, at x=-1, f has local maximum.
Answer:a)at x=-1 ,f has local maximum.
2.) if f'(4)=0 and f''(4)=0
We know that when f''(x)=0 then test fails then the function has not maximum or minimum.
Therefore, at x=4 , f has not a maximum or minimum.
Answer:c) at x=4, f has not a maximum or minimum.
Answer:
?
Step-by-step explanation:
linear inequality
The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system
Answer:
e) 0.14
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a driver does not have a valid driver's license.
B is the probability that a driver does not have insurance.
We have that:
In which a is the probability that a driver does not have a valid driver's license but has insurance and 
is the probability that a driver does not have any of these things.
By the same logic, we have that:
We start finding these values from the intersection.
4% have neither
This means that 
6% of all drivers have no insurance
This means that 
. So
12% of all drivers do not have a valid driver’s license
This means that 
So
The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about
So the correct answer is:
e) 0.14
Answer:
44, parallel, equals half
Step-by-step explanation:
i am not sure is this is correct but, I think that x+5 that x is 27 and the other one is 12 and the 27+5 is 32 and 32+12 is 44 so i am guessing that the BD side is 44, i guess and about the other , the first black space is parallel and the second is equals half
