2 answers:

7 0

Exponential functions help us in reducing higher dimensional equivalents into smaller ones , simply , we have an advantage over using exponents , indices , simultaneously ,

we can substitute x² = t in any equation which has raised to the power 4 , it'll result in t² for sure ,

SO , the above illustration is the most basic and common application of exponential functions , rest is utilized in reducing logarithmic , trigonometric functions and so on more

Answer:

The special matter about exponential functions is that they can be very beneficial in day to day situations.

Exponential functions are beneficial to carbon date artifacts, compute investments, help coroners determine the death time, model populations as well as many other applications.

Three of the very common applications for exponential functions:

population growth
exponential decay
compound interest.

A 7-digit telephone number has the form abc - xxxx, where x, b, and c can be any digit 1 - 9 and a is restricted to 3 - 9. how m

9966 [12]

The total 7-digit telephone numbers has the form abc-xxxx which are possible are 3,720,087

It is given that,

A 7-digit telephone number has the form = abc - xxxx

Also, x, b, c can have any digit between 1-9

And, a is restricted to between 3-9

We need to find the possible number of combinations of a 7-digit telephone number having the form abc-xxxx

Then, number of digits that can be placed at the place of 'a' = 7 type of digits (3 to 9)

Number of digits that can be placed at the place of x, b and c= 9 type of digits (1 to 9)

Suppose, we put a number from 3 to 9 at 'a', so total possibilities are 7

Similarly, at 'b' we put a number from 1-9, so total possibilities are 9 and so on so forth

Thus total 7-digit telephone numbers which have the possible combinations can be

= 7*9*9*9*9*9*9

= 3,720,087

The label on the paint container states that its average coverage rate is 275 square feet per gallon. What is the difference

Katen [24]

Answer:

<u><em>The rate of paint coverage of Angela is 13ft²/gallon less than the average rate indicated on the label of the container.</em></u>

Explanation:

This question is the second part (Part B) of a two-parts question.

You need solve the first part first, to use the result as input of this second part.

Please, find attached the whole question.

<u>Part A. Angela's rate of paint coverage</u>

$\text{Rate of paint coverage}=\frac{\text{gallons of paint used}}{area}$

Convert the mixed numbers to improper fractions:

$42\frac{2}{3}=42+\frac{2}{3}=\frac{3\times 42+2}{3}=\frac{128}{3}$ [this is square yards]

$1\frac{1}{3}=1+\frac{1}{3}=\frac{3\times 1+1}{3}=\frac{4}{3}$ [this is gallons]

Now calculate the rate:

$\frac{\frac{128}{3}}{\frac{4}{3}}=\frac{128}{3}\times \frac{3}{4}=\frac{128}{4}=32$ [that is square yards per gallon]

Part. B.

To compare the rates first change 32 yard²/gallon to feet²/gallon.

$1 yd^2=9ft^2\implies 1=9ft^2/1yd^2\\ \\ 32yd^2/gallon\times 9ft^2/1yd^2=288ft^2$

<h2>Difference:</h2>

288 ft²/gallon - 275ft²/gallon = 13ft²/gallon

5627 to the nearest thousand

Marizza181 [45]

Answer:

6000

Step-by-step explanation:

by observation, we can see that the digit in the thousands place is the number 5. This is the number that we need to either round up or down.

in order to determine if we should round up or down, we need to look at the number which is immediately to the right of this number. If this number is greater than 5, then we round the thousands place up, otherwise it remains the same

In this case, the number immediately to the right (i.e in the hundreds place) is the number 6. This number is greater than the number 5, hence we need to round the number in the thousands (i.e 5) place up to 6, giving us 6000
