Marco bicycles 20 miles in 2 1/2 hours. What is the average rate in miles per hour?

Mathematics
1 answer:
olga nikolaevna [1]3 years ago
5 0

Answer:

The average rate in miles per hour is 8 miles per hour

Step-by-step explanation:

In this question, we are concerned with finding what Marco’s average rate is, if he cycles 20 miles in 2 1/2 hours

For calculation simplification, we should know that 2 1/2 hours is same as 2.5 hours

Now mathematically, the average speed = Distance/Time

Thus, our disgrace here is 20 miles and our time taken to cover this distance is 2.5 hours

Thus, the average speed = 20/2.5 = 8 miles/hour

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. y=(3x+4)(-2x-3)
MissTica
Y=(3x+4)(-2x-3)=-6x^2-4x-9x-12=-6x^2-13x-12.
It is a quadratic function because it has x in power 2 (x^2)

If the limit of f(x) as x approaches 8 is 3, can you conclude anything about f(8)?
natali 33 [55]

If the limit of f(x) as x approaches 8 is 3, can you conclude anything about f(8)? The answer is No. We cannot. See the explanation below.

<h3>What is the justification for the above position?</h3>

Again, 'No,' is the response to this question. The justification for this is that the value of a function does not depend on the function's limit at a given moment.

This is particularly clear when we consider a question with a gap. A rational function with a hole is an excellent example that will help you answer this question.

The limit of a function at a position where there is a hole in the function will exist, but the value of the function will not.

<h3>What is limit in Math?</h3>

A limit is the result that a function (or sequence) approaches when the input (or index) near some value in mathematics.

Limits are used to set continuity, derivatives, and integrals in calculus and mathematical analysis.
