To solve this determine when C=S where C is cost and S is sales.
Cost = 37720+11.5x where x is the number of books.
Sales = 19.50x.
37720+11.5x=19.5x
37720=8x
4840=x
Answer:
A) f(x) = |x|
B) f(x) = -|x+3| + 3
Step-by-step explanation:
Absolute value functions
The general form of an absolute value function is f(x) = a|x-b| +c
a indicates the 'amplitude' or multiplier
b indicates horizontal shift
c indicates vertical shift
The turning point of f(x) = |x| is (0, 0)
a = y/x when b = 0 and c = 0
A) f(x) = |x|
Since the turning point is still (0, 0) there is no horizontal nor vertical shift, meaning b = 0 and c = 0
We have the point (2, 2), thus a = 2/2 = 1
f(x) = a|x-b| + c
f(x) = |x|
B) f(x) = -|x+3| + 3
The turning point is at (-3, 3) b = -3 and c = +3
We have the point (3, -3), thus a = y/x = -3/3 = -1
f(x) = a|x-b| + c
f(x) = (-1) (|x-(-3)|) + (+3)
f(x) = -|x+3| + 3
7.25 is the same as
written as a mixed number. However, .25 is
of 100.
In this case, while rewriting your mixed number, 7.25 is the same as
, so that would be your answer.
7.25 ⇒
7 1/4
Answer:
The number of palindromes is
when n is even and
when n is odd
Step-by-step explanation:
From the question we are told that
The length of the string is
Generally palindrome is evaluated by considering the first part of a string
When the the length of the string is an even number then
it means that the first part of the string is
Hence the number of bit strings of length n that are palindromes is evaluated as
But When the the length of the string is an odd number then
it means that the first part of the string is
Hence the number of bit strings of length n that are palindromes is evaluated as
Generally each bit could be either 0 or 1
Hence the number of palindromes is
when n is even and
when n is odd
