On most state highways, the fine for speeding depends on the speed of the car. In a certain state, suppose the fine as a functio

Georgia [21]

Graphs can be used to model real world situations.

<em>The coordinates of the graph is gotten by adding 5 to the y-values of the function (see attachment for graph)</em>

The function of the graph is represented as (n, f(n)); where

<em /> $n \to$ <em> speed</em>

<em /> $f(n) \to$ <em> fine for over speed</em>

When the fine increases by $5 for every speed limit.'

The new function becomes:

$g(n) = f(n) +5$

<u />

<u>The points on the graph are represented as:</u>

$f(5) = 25$

$f(10) = 50$

$f(15) = 75$

$f(20) = 110$

$f(25) = 150$

$f(30) = 200$

$f(35) = 270$

So, the new points would be calculated as follows:

$g(n) = f(n) +5$

$g(5) = 25 + 5 = 30$

$g(10) = 50 + 5 = 55$

$g(15) = 75 + 5 = 80$

$g(20) = 110 + 5 = 115$

$g(25) = 150 + 5 = 155$

$g(30) = 200 + 5 = 205$

$g(35) = 270 + 5 = 275$

See attachment for the new graph

Make h the subject of the formula<br><br> t=gh/10

Lera25 [3.4K]

Here, t = gh/10
gh = 10t
h = 10t/g

In short, Your Answer would be 10t / g

Hope this helps!

Rachel is a stunt driver, and she's escaping from a building that is about to explode! DDD represents Rachel's remaining distanc

skelet666 [1.2K]

Answer:

38 m/s

Step-by-step explanation:

We are given that

D represent Rachel's remaining distance( in meters ) as a function of time is given by

$D=-38t+220$

We have to find the Rachel's speed.

We know that

$Velocity=\frac{ds}{dt}$

Substitute the values then we get

$v=\frac{d(-38t+220)}{dt}=-38 m/s$

$Speed =\mid v\mid$

$Speed =\mid -38\mid =38m/s$

Hence, the Rachel's speed is given by =38 m/s
