It takes an insect 15s to crawl 1ft. How many hours would it take the insect to crawl 1mi if the insect crawls at the same rate?

1 answer:

6 0

5280 feet in a mile x 15 seconds = 79200 seconds to go 1 mile
79200 seconds / 3600 (seconds in an hour) = 22 hours
It would take 22 hours for the insect to crawl a mile.

Ok, lets visualize this scenario. We have a tank that is holding10450 ml of water. Then it tells use it is leaking at a rate of 270 ml per minute. Well, leaking would suggest something is being subtracted. Also, per minute means it is being subtracted each minutes so we use an x to represent the minutes. Ok, lets build the model

10450 - 270x = 0
The model above will tell us how many minutes it will take for the tank to be empty.

If we insert a number for x, the model below will tell us how many ml has leaked for the number of minutes we inserted into x.
10450 - 270x

How does h(x)=-2x+5 change over the interval from x=1 to x=2?

Akimi4 [234]

As the rate of change of function is negative from x=1 to x=2, the function decreases at this interval.

Step-by-step explanation:

We have to find the rate of change of the function

The rate of change of function is given by:

$Rate\ of\ change = \frac{h(b)-h(a)}{b-a}$

Given function is:

$h(x) = -2x+5$

Here

a =1

b = 2

So,

$h(2) = -2(2) +5\\= -4+5\\= 1\\h(1) = -2(1) +5\\= -2+5\\= 3$

Putting the values in the formula

$Rate\ of\ change = \frac{1-3}{2-1} = -2$

As the rate of change of function is negative from x=1 to x=2, the function decreases at this interval.

Express the volume of the box as a<br>polynomial in the variable x

Whitepunk [10]

The volume of the box as a polynomial in the variable x is x(12 - 2x)(7 - 2x)

<h3>How to determine the volume?</h3>

The complete question is added as an attachment

From the attached image, we have:

Length = 12 - 2x

Width = 7 - 2x

Height = x

The volume is calculated as:

Volume = Length * Width * Height

Substitute the known values in the above equation

Volume = (12 - 2x) * (7 - 2x) * x

This gives

Volume = x(12 - 2x)(7 - 2x)

Hence, the volume of the box as a polynomial in the variable x is x(12 - 2x)(7 - 2x)
