If f(x( =1/9x-2 what is f-1(x)

1 answer:

4 0

You first switch f(x) with x in this equation x=19f(x)−2 Then you solve for f(x). 9f(x)−2=1x 9f(x)=1x+2 f(x)=1/9x+2/9 Then you simply repalace f(x) with f^-1(x) It will look like this f−1(x)=1/9x+2/9
Hope i could help

Need Help ASAP!!.

mihalych1998 [28]

Answer:

Part 1) Greta's right, the triangle is incorrect.

Part 2) $34,203\ ft$

Part 3) The height of the tree is $23.3\ ft$ , Trey’s house is not at risk

Step-by-step explanation:

Part 1) we know that

In the right triangle of the figure

$sin(30\°)=\frac{1}{2}$

$sin(30\°)=\frac{6\sqrt{3}}{12}=\frac{\sqrt{3}}{2}$

Compare

$\frac{1}{2}\neq\frac{\sqrt{3}}{2}$

therefore

The triangle is not correct

Because

The side adjacent to the 30 degree angle should be $6\sqrt{3}$ and the side opposite the 30 degree angle should be $6$

Part 2)

Let

x--------> the distance from the airplane to the SCCA (hypotenuse of the right triangle)

we know that

$sin(17\°)=\frac{10,000}{x}$

$x=\frac{10,000}{sin(17\°)}$

$x=34,203\ ft$

Part 3)

Let

x--------> the height of the tree

we know that

$tan(43\°)=\frac{h}{25}$

$h=tan(43\°)(25)=23.3\ ft$

$23.3\ ft< 25\ ft$

therefore

Trey’s house is not at risk

In ΔVWX, the measure of ∠X=90°, WV = 17, VX = 15, and XW = 8. What ratio represents the sine of ∠W?

Dahasolnce [82]

Answer:

$Sin \ \angle W=\frac{15}{17}$

Step-by-step explanation:

-In a right triangle, the Sine of the base acute angle is usually given as:

$Sin \angle (base)=\frac{Opposite \ Length}{Hypotenuse}$

-In ΔVWX,, VX is the opposite and WV the hypotenuse.

-Therefore, sine of ∠Wis calculated as;

$Sin \ \angle W=\frac{Opp}{Hyp}\\\\=\frac{15}{17}$

Hence, sine of ∠W is given represented by the ratio $\frac{15}{17}$
