Second picture, one below it
Answer:
Find the places where the derivative is zero and the second derivative is positive.
Step-by-step explanation:
By definition, a function has a minimum where the first derivative is zero and the second derivative is positive.
That will be a "local" minimum if there are other points on the function graph that have values less than that. It will be a "global" minimum if there are no other function values less than that. A global minimum is also a local minimum.
__
On a graph, a local minimum is the bottom of the "U" where the graph changes from negative slope to positive slope.
I don't know how to do this:(
so sorryyyy
Answer:
1) If the order doesn't matter, there are 36 possible outcomes.
2) If the order does matter, there are 181,440 possible outcomes.
Step-by-step explanation:
1) In the case when the order doesn't matter , we have to calculate a combination of 7 screws in 9 holes.
We use the formula for combinations:
being r: the number of screws and n: the number of holes.
2) When the order does matter, the possible outcomes are called permutations. We have permutations of 7 screws in 9 holes.
We use the formula for permutations:
Answer:
b= 6/5
b = 1 1/5
Step-by-step explanation:
We can solve this using cross products
(3b-4) (b-2)
--------- = ---------
4 8
8* (3b-4) = 4*(b-2)
Distribute
24b -32 = 4b -8
Subtract 4b from each side
24b-4b -32 = 4b-4b-8
20b -32 = -8
Add 32 to each side
20b -32+32 = -8 +32
20b =24
Divide each side by 20
20b/20 = 24/20
b= 24/20
Dividing the top and bottom by 4
b = 6/5
b = 1 4/20
=1 1/5
