Graph (a) represents an exponential decay.
Here, two graph are shown and we have to check which represent exponential decay.
What is exponential decay?
Exponential decay occurs when a quantity decreases by the same factor over equal intervals of time.
Now,
From the graph, we have
In graph (a), as x increases the function decreases.
Hence this graph shows exponential decay.
In graph (b), as x increases the function increases.
So, Graph (a) represents an exponential decay.

its sorta hard to do fractions with typing
Answers
Answer:
slope=(y2-y1)/(x2-x1)
=(1/b-1/a)/(b-a)
=((a-b)/ab)/(b-a)
=(a-b)/ab(b-a)
=(a-b)/(-(ab(a-b))
=-1/ab
The slope of the line containing the points should be considered as the [tex]-1/ab[/tex]
Calculation of the slope of the line;Since we know that
slope should be
[tex]=(y2-y1)/(x2-x1)\\\\=(1/b-1/a)/(b-a)\\\\=((a-b)/ab)/(b-a)\\\\=(a-b)/ab(b-a)\\\\=(a-b)/(-(ab(a-b))\\\\=-1/ab\\\\[/tex]

Answers
Answer:
Tayler has 35 SHKITTLES IN ALL
Step-by-step explanation:
Since Tayler has 20 red Skittles, and the ratio of blue skittles to red skittles is 3 to 4, that means that Tayler has 3/4 as many blue skittles as she does red skittles. 3/4 of 20 is 15

Remember PEMDAS. First, do what's in the parentheses (P) going left to right (there's only one in this case so we dont need to). [tex](2 \times 5) {}^{2} - 2 \times 5 {}^{2} →(10) {}^{2} - 2 \times 5 {}^{2}[/tex]
Then do the exponents (E) going left to right. [tex](10) {}^{2} - 2 \times 5 {}^{2}→100 - 2 \times 25[/tex]
Now do multiplication and division (MD) going left to right (there's only one situation of multiplication in this case so we don't need to do division or go from left to right).
[tex]100( - 2 \times 25)→100 - 50[/tex]
Now do addition (AS) going left to right (there's only one situation of subtraction in this case so we don't need to do addition or go from left to right).
[tex]100 - 50 = 50[/tex]
The answer simplified is [tex]50[/tex].

Answers
Answer: -9 degrees Fahrenheit
Step-by-step explanation:
Given: Temperature at 6:00 AM = -12 degrees Fahrenheit
Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit
Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]
Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours

Determine whether each function is even, odd, or neither.
1. f(x) = sqrt x^2 - 9
2. g(x) = |x-3|
3. f(x) = 1/2
4. f(x) = x/x²-1
5. g(x) = x + x^2
Answers
Answer:even,neither,odd,neither
Step-by-step explanation:I’m not explaining I just gave you the answers
1. [tex]f(x) = \sqrt{x^2 - 9}[/tex] is even.
2. g(x) = |x - 3| is neither even nor odd.
3. f(x) = 1/2 is neither even nor odd.
4. [tex]f(x) = x / (x^2 - 1)[/tex] is odd.
5. [tex]g(x) = x + x^2[/tex] is neither even nor odd.
To determine whether each function is even, odd, or neither, we need to apply the definitions of even and odd functions:
1. An even function satisfies f(x) = f(-x) for all x in its domain.
2. An odd function satisfies f(x) = -f(-x) for all x in its domain.
Let's analyze each function:
1. [tex]f(x) = \sqrt{x^2 - 9}[/tex]
To determine if this function is even or odd, we need to check f(x) and f(-x):
[tex]f(x) = \sqrt{x^2 - 9}\\f(-x) = \sqrt{(-x)^2 - 9} = \sqrt{x^2 - 9}[/tex]
Since f(x) = f(-x), the function is even.
2. g(x) = |x - 3|
To determine if this function is even or odd, we need to check g(x) and g(-x):
g(x) = |x - 3|
g(-x) = |-x - 3|
Since |-x - 3| is not equal to |x - 3|, the function is neither even nor odd.
3. f(x) = 1/2
Since this is a constant function (not dependent on x), it is neither even nor odd.
4. [tex]f(x) = x / (x^2 - 1)[/tex]
To determine if this function is even or odd, we need to check f(x) and f(-x):
[tex]f(x) = x / (x^2 - 1)\\f(-x) = (-x) / ((-x)^2 - 1) = -x / (x^2 - 1)[/tex]
Since f(x) = -f(-x), the function is odd.
5. [tex]g(x) = x + x^2[/tex]
To determine if this function is even or odd, we need to check g(x) and g(-x):
[tex]g(x) = x + x^2\\g(-x) = -x + (-x)^2 = -x + x^2[/tex]
Since g(x) is not equal to g(-x), the function is neither even nor odd.
