Based on the tables given and the functions represented, the two functions that are inverses of each other are Tables 3 and 4.

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.

" Work out the surface area of this cylinder if the diameter of the cylinder is 8 cm and height is 16.8 cm."

The surface area of the cylinder of diameter 8 cm and height 16.8 cm would be 547.616 cm sq.

The surface area of the cylinder of the radius of the base r and the height h,

A = 2πr ( r + h)

We have been given as

diameter = 8 cm

Height = 16.8cm

The radius = 8/2 = 4cm

The surface area of the cylinder

A = 2πr ( r + h)

A = 2 x 3.14 x 4 ( 4 + 16.8)

A = 25.12 (21.8)

A = 547.616 cm sq.

Hence, The surface area of the cylinder of diameter 8 cm and height 16.8 cm would be 547.616 cm sq.

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.

The sides of the triangle are (d) 12√2, 12√2, 24

The given parameters are:

In 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

Evaluate

Adjacent = 12√2

This means that:

Opposite = 12√2

Hence, the sides of the triangle are (d) 12√2, 12√2, 24

Answer:

(-14, 12) and (5, 12)

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

Answer:

Domain: x < 5

Range: all numbers, -∞, ∞

This is because the problem will be able to be solved with multiple solutions as long as there are no specific values assigned to x. The problem will have a solution from a range of negative infinity to infinity, meaning every number or solution you can think of.

The transformation R090 °ry means a rotation of 90 degrees followed by a reflection across the y-axis

i.e.

(x, y) => (y, -x) => (-y, -x)

The transformation ry ° R090 means a reflection across the y-axis followed by a rotation of 90 degrees

The equation of the function is f(x) = -5x + 10

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
