Find the inverse of the function f f (x ) equals 9 x + 7

MrMuchimi

Note: Your question seems a little bit ambiguous. So, I am assuming the given function f(x)=9x+7.

Thus, I am solving based on it. It would still clear your concept.

Answer:

The inverse of f(x)=9x+7

$\frac{x-7}{9}$

Step-by-step explanation:

Given the function

$f(x)=9 x + 7$

A function g is the inverse of function f if for y=f(x), x=g(y)

Replace x with y

$x=9y+7$

solve for y

$9y=x-7$

$y=\:\frac{x-7}{9}$

Therefore,

The inverse of f(x)=9x+7 is:

$\frac{x-7}{9}$

i.e.

$\mathrm{Inverse\:of}\:9x+7:\quad \frac{x-7}{9}$

In the right triangle below, tanA = 0.45. What is the approximate length of AB?

kodGreya [7K]

Answer with Step-by-step explanation:

We are given that:

tanA = 0.45

tanA= $\dfrac{Perpendicular}{Base}$

= $\dfrac{BC}{AC}$

⇒ $\dfrac{BC}{AC}$ =0.45

⇒ $\dfrac{9}{AC}$ = $\dfrac{45}{100}$

⇒ $\dfrac{9}{AC}$ = $\dfrac{9}{20}$

⇒ AC= 20

Hence, by pythagoras theorem

AB²=AC²+BC²

AB²=20²+9²

AB²=481

⇒ AB=21.9 units

Hence, the approximate length of AB is:

22 units
