Rachel is a stunt driver, and she's escaping from a building that is about to explode! D represents Rachel's remaining distance (in meters) as a function of time T (in seconds) D=−38t+220 What is Rachel's speed?

Rachel's speed is -38 meters per second.

Step-by-step explanation:

The velocity is the derivative of the position.

In this problem, we have the following position equation:

So

The derivative of the sum is the sum of derivatives.

The derivative of a constant is 0, and of at is a. So

Rachel's speed is -38 meters per second.

Step-by-step explanation:

The speed is the rate of change of the remaining distance in time, which is found by deriving the known formula:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

it can be to see completed examples before writing, in order to examine what makes for an effective piece. see how these intros give some context before posing the topic and lead naturally into the body paragraphs, where the evidence will be listed. you can imagine how the author has organized the rest of the piece.

"we buried my cousin last summer. he was 32 when he hanged himself from a closet coat rack in the throes of alcoholism, the fourth of my blood relatives to die prematurely from this deadly disease. if america issued drinking licenses, those four men—including my father, who died at 54 of liver failure—might be alive today. that is a good example piece   some steps that are .

. writing something that happened to you

.read a book you like to get ideas from there

. lastly you can make a venn diagram

hope this plz make brainliest
