Answer:
K= 11
Step-by-step explanation:
You solve for K by subtracting 14 by 25.
25-14= 11
When k is pluged into k
11 the statement is true because it is equal to 11.
When plugged into k+14
25;
11+14 =25.
That statement is also true because 25 is equel to 25.
Well as you can see 5 x 2/3= 3 1/3 there is 7 steps to figure it out
1. set up the problem
5 x 2/3
2. put a 1 on 5 to make it a fraction
5/1 x 2/3
3. multiply and divide
(5 x 2) / (1/3)
4. find out the answer
10/3
5. turn the answer into a mixed fraction
10 divided by 3= 3.1 3 stays the same you don't need to say 1
6. it equals
3 1/3
7. so the answer is
3 1/3
The first derivitive is the slope
a positive 1st deriviive is positive slope or increasing
a negaitve 1st derivitive is negative slope or decreasing
the 2nd derivitive tells about the concavity
a negative second derivitive means it is concave down at that point
a positive 2nd derivitive means it is concave up at that point
so
first one is false
2nd is true
3rd is false because it could possibly be a minimum as well
answer is 2nd one
