1 answer:

8 0

<u>common difference</u> (d) of an arithmetic sequence is equal to the the difference of two consecutive terms of the sequence,

so,

=》

$d = 10 - 4$

=》

$d = 6$

hence, the <u>common difference</u> of given AP is 6

Lf f(x) = 5x, what is f^-1(x)?

Nonamiya [84]

Answer: $f^{-1}(x)=\frac{x}{5}$

Step-by-step explanation:

By definition the domain of an inverse function $f^-1(x)$ is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).

If you have a function $f(x)=5x$ , then to find the inverse function, follow these steps:

1. Make $y=f(x)$

$f(x)=y=5x$

$y=5x$

2. Solve for the variable "x":

$x=\frac{y}{5}$

3. Exchange the variable "x" with the variable "y":

$y=\frac{x}{5}$

4. Exchange "y" with $f^{-1}(x)$ . Then the inverse function is:

$f^{-1}(x)=\frac{x}{5}$

27=3 raised to power (2x_1)

Ivahew [28]

Answer:

x = 2

Step-by-step explanation:

$27=3^{2x-1}\\\\3^{3}=3^{2x-1}\\$

Bases are equal. So, compare powers

2x - 1 = 3

Add 1 to both sides,

2x = 3+1

2x = 4

Divide both sides by 2

x = 4/2

x = 2
