Answer:

f⁻¹(x) = 5th root(x/4 - 5/4)

Step-by-step explanation:

f(x) = 4x^5 + 5

substitute y for f(x):

y = 4x^5 + 5

swap x and y:

x = 4y^5 + 5

subtract 5 from each side:

x - 5 = 4y^5

divide both sides by 4:

(x - 5)/4 = y^5

get the 5th root of each side:

y = 5th root(x/4 - 5/4)

f⁻¹(x) = 5th root(x/4 - 5/4)

Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1

vlabodo [156]

Answer:

A) $x = y^{2}$

Step-by-step explanation:

An equation is a function of $x$ when $x$ is the independent variable, that is:

$y = f(x)$ (1)

Where $y$ is the dependent variable.

According to this, $x = y^{2}$ does not represent a function of $x$ , since the independent variable is a function of $y$ , that is, $x = f(y)$ . Therefore, the correct answer is A.

Two cards are drawn from a standard deck without replacement. What is the probability that the first card is a spade and the sec

Verizon [17]

Answer:

The answer is 0.123.

Step-by-step explanation:

You want to find the intersection between P(Spade) and P(Red). Knowing that there's no replacement, the probability will be given by the formula:

⇒ P(Spade∩Red) = P(Spade)*P(Red/Spade)

⇒ P(Spade∩Red) = P(Red)*P(Spade/Red)

Either formula works, but I'm going to choose to work with the first formula.

Therefore:

P(Spade) = $\frac{13}{52}$

P(Red/Spade) = $\frac{26}{52-1}$

So:

P(Spade∩Red) = $\frac{13}{52}$ * $\frac{26}{51}$ = $\frac{13}{102}$ = $0.123$

Select inductive reasoning, deductive reasoning, or neither. A courtroom spectator merely looks at the defendant and says, "He's

I'd say deductive.
inductive would be looking at his past crimes and asuuming that he's not guilty ,only to reach a contradiction. some thing like that
