Find the slope of the line containing the points ( a , 1/a ) a n d ( b , 1/b )
its sorta hard to do fractions with typing
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]
Hence, The slope of the line containing the points should be considered as the [tex]-1/ab[/tex]

Answer:
[tex]50[/tex]
Step-by-step explanation:
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].

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
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.

The temperature at 6.00 am was - 12 the temperature increased by 1/2 each hour for 6 hours what was the temperature in degrees Fahrenheit at noon
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
= -12+3 degrees Fahrenheit
= -9 degrees Fahrenheit
Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit
