The function on the table is decreasing on the interval [-2, 0).
Over what interval is the function shown in the table decreasing?
A function is decreasing if, as x increases, f(x) decreases.
We can see that at x = -2, f(-2) = 12.
Then at x = 0, f(0) = 0.
And for the value after that:
x = 1, f(1) = 3
So now the function increases. Then we conclude that the function is decreasing on the interval [-2, 0), and after that the function increases.

How many combinations of 3 playing cards (from a 52-card deck) exist?
25,000
1,649
523
its not 22,100 btw....
Answers
Answer:
Step-by-step explanation:
To determine the number of combinations of 3 playing cards from a standard 52-card deck, we can use the formula for combinations, which is given by:
C(n, k) = n! / (k!(n-k)!)
Where n is the total number of items (in this case, the number of cards in the deck) and k is the number of items chosen (in this case, 3 cards).
Plugging in the values:
n = 52 (total number of cards in the deck)
k = 3 (number of cards chosen)
C(52, 3) = 52! / (3!(52-3)!)
Calculating the factorial terms:
52! = 52 x 51 x 50 x ... x 3 x 2 x 1
3! = 3 x 2 x 1
(52-3)! = 49! = 49 x 48 x ... x 3 x 2 x 1
Simplifying the equation:
C(52, 3) = 52 x 51 x 50 / (3 x 2 x 1)
Cancelling out the common factors:
C(52, 3) = (52 x 17 x 25) / (3 x 2 x 1)
C(52, 3) = 22,100
Therefore, there are 22,100 combinations of 3 playing cards that can be chosen from a 52-card deck.

Answer:

Step-by-step explanation:
From inspection of the points given, we can see that all pairs of points share the same y-values.
Therefore, each pair of points are on the same horizontal line.
To find the distance between the points, simply find the difference between the x-values.
Given points: (-14, 12) and (5, 12)
⇒ Difference between x-values = 5 - (-14) = 19 units
Given points: (-5, 19) and (12, 19)
⇒ Difference between x-values = 12 - (-5) = 17 units
Given points: (-20, 5) and (1, 5)
⇒ Difference between x-values = -20 - 1 = -21 = 21 units
Given points: (14, 12) and (5, 12)
⇒ Difference between x-values = 14 - 5 = 9 units

Based on the tables given and the functions represented, the two functions that are inverses of each other are Tables 3 and 4.
Which functions are inverses of each other?When two functions are said to be inverses of each other, it means that the value of x is one is the corresponding value of y in the other function.
For instance, when the point is (5, 16) in one function, the other function's point would be (16,5).
The functions that are inverses are therefore Tables 3 and 4 as shown attached.

A function, f, has an x-intercept at (2,0) and a y-intercept at (0.10)
Answers
The equation of the function is f(x) = -5x + 10
How to determine the function equation?The points are given as:
x-intercept at (2,0) and a y-intercept at (0,10)
A linear function is represented as:
y = mx + b
Where b is the y-intercept.
The y-intercept at (0,10) means that:
b = 10
So, we have:
y = mx + 10
The x-intercept at (2,0) means that:
x = 2, when y = 0
Substitute these values in y = mx + 10
0 = 2m + 10
Subtract 10 from both sides
2m = -10
Divide both sides by 2
m = -5
Substitute m = -5 in y = mx + 10
y = -5x + 10
Hence, the equation of the function is y = -5x + 10

How to determine the side lengths?The given parameters are:
Hypotenuse = 24Angle = 45-45-90 degree anglesIn a 45-45-90 degree angle triangle, we have:
Hypotenuse = Opposite√2 and Hypotenuse = Adjacent√2
This means that:
Opposite =Adjacent
So, we have:
24 = Adjacent√2
Divide both sides by √2
Adjacent = 24/√2

Adjacent = 12√2
