Answer:

$y = 7x - 5$

Step-by-step explanation:

$\frac{1}{2} (2y + 10) = 7x \\ \frac{2y}{2} + \frac{10}{2} = 7x \\ y + 5 = 7x \\ y = 7x - 5$

A statue is mounted on top of a 25 foot hill. From the base of the hill to where you are standing is 53 feet and the statue subt

bixtya [17]

Answer:15.848 ft

Step-by-step explanation:

Given Height of hill is 25 foot

and distance between Hill foot and feet is 53 feet

angle subtended by 12.4^{\circ}[/tex]

From diagram

$tan\theta =\frac{25}{53}$

$tan(\theta +12.4)=\frac{h+25}{53}$

and we know $tan(A+B)=\frac{tanA+tanB}{1-tanAtanB}$

using above formula

$tan(\theta +12.4)=\frac{tan\theta +tan(12.4)}{1-tan(\theta )tan(12.4)}$

$\frac{h+25}{53}=\frac{\frac{25}{53}+0.219}{1-0.219\times \frac{25}{53}}$

$0.896h+22.407=25+11.607$

h=15.848 ft

The inverse of the function f(x) = x + 10 is shown.

IgorLugansk [536]

Answer:

So, the answer is 20

Step-by-step explanation:

$f(x) = \frac{1}{2} x + 10 = = = > \\ f(x) - 10 = \frac{1}{2} x = = = > \\ 2f(x) - 20 = x = = = > \\ {f}^{ - 1} (y) = 2y - 20 = = = > {f}^{ - 1} (x) = 2x - 20$
