First we need to find inverse function of f(x) which is written in a form of (f(x))^(-1)
That means that we are actually looking for function f(y) and we need to solve this equation for "y"

y=(4x + 1)/3
3y = 4x + 1
4x = 3y - 1
x = (3y - 1) / 4
f(y) = (3y - 1)/4

Now we simply put the value of 3 instead of y and find the answer:
f(y=3) = (3*3-1)/4 = 2

Answer is 2

If you select one card at random from a standard deck of 52 cards, what is the probability that the card is a five AND a club?
horsena [70]

Probability is expressed as

number of favorable outcomes/number of total outcomes

The number of cards in a deck is 52(total outcomes)

Recall, there is only 1 five of clubs in a deck of cards(favorable outcomes)

Thus, the probability that the card is a five AND a club is 1/52

sashaice [31]

Answer:

16 cm²  

Step-by-step explanation:

The figure is a trapezoid with two parallel sides.

The formula for the area is

A = ½(a + b)h

Data:

a = 5 cm

b = 3 cm

h = 4 cm

Calculation:

A = ½(5 + 3) × 4 = ½ × 8 × 4 = 16 cm²

The area of the trapezoid is 16 cm².
