2 Select the correct answer. What is the inverse of function ? F(x)=10/9x+11 A.f-1(x)=9x-99/10 B.f-1(x)=9/10x+11 C.f-1(x)=9x+11/

Lilit [14]

Consider f(x)=y.

$\begin{gathered} f(x)=y \\ x=f^{-1}(y) \end{gathered}$

Simplify the equation f(x)=y to obtain the value of x in terms of y.

$\begin{gathered} f(x)=y \\ \frac{10}{9}x+11=y \\ \frac{10}{9}x=y-11 \\ 10x=9y-99 \\ x=\frac{9y-99}{10} \end{gathered}$

So inverse of function is,

$f^{-1}(x)=\frac{9y-99}{10}$

Correct nswer is A part.

Calculate cos theta to two decimal places

Ghella [55]

Answer:

B. 0.72

Step-by-step explanation:

In order to find the answer we need to use the following formula:

$a^2=b^2+c^2-2bc*cos(\theta)$ where:

a, b, c are the length of the sides and $\theta$ the angle, so:

$7^2=10^2+8^2-(2*10*8)*cos(\theta)$

$49=164-(160)*cos(\theta)$

$cos(\theta)=0.71875$

In conclusion, $cos(\theta)=0.72$ , so the answer is B.
