If the exponential model f(x)=14(5)x is written with the base e, it will take the form A0ekx. What is A0 and what is k?

Answers

Answer 1

Answer:

We have:

f(x) = 14*(5)^x

And we want to write this in the form:

g(x) = A*e^(k*x)

We want to have f(x) = g(x)

This is ratter easy.

The general case is:

A*(r)^x = B*e^(k*x)

Here we have:

A = B

Then:

(r)^x = e^(k*x)

Now we can remember the relation:

(a^x)^y = a^(x*y)

Then we can write:

e^(k*x) = (e^k)^x

Then we have:

(r)^x = (e^k)^x

Then we must have:

r = e^k

Now let's go to our case:

14*(5)^x = A*e^(k*x) = A*(e^k)^x

Then we have:

14 = A

5 = (e^k)

With this equation we can find the value of k.

ln(5) = ln(e^k) = k

ln(5) = k

Then the equation g(x) is:

g(x) = 14*e^(ln(5)*x)

Answer 2

Answer:

A0=14 k +ln9

Step-by-step explanation:

To rewrite the model with the base e, we use the fact that for all b>0,

b=eln(b)

Using this property, and then the power property of logarithms, on 9x, we find that

(9)x=eln(9x)=exln(9)=e(ln(9))x

So we find that

14(9)x=14eln(9)x

So A0=14 and k=ln(9).

If three independent events happen one after the other, which of the following sample space tools cannot be used?

Answers

If three independent events happen one after the other, a list of the sample space tools cannot be used.

correct option: A list

What is an independent events?

If the likelihood of the occurrence of one event has no bearing on the likelihood of the other, then the two occurrences are independent. The likelihood that both events A and B will occur is defined mathematically as being equal to the product of the probabilities of A and B. This is how independent occurrences A and B are expressed mathematically.

Thus, if three independent events happen one after the other, a list of the sample space tools cannot be used.

Juan wants to buy some protein bars and magazines for a trip.
He has decided to buy three times as many protein bars as
magazines. Each protein bar costs $0.70 and each magazine
costs $2.50. The sales tax rate on both types of items is 734%.
How many of each item can he buy if he has $20.00 to spend?


What Is the answer I don’t know

Answers

Answer:

HI there! I am really sorry if i get this wrong, but please apperciate!

Thank you! :)

Step-by-step explanation:

So I worked this out like this:

Protein bars: 0.70 * 3 = 2.1

Magezines: 2.50

734% are the taxes as it was written. 734% decimal version is 7.34.

This is what I did next:

7.34 plus 2.1 times 2 equals  18.88. So, you can buy 2 protein bars.

7.34 plus 2.50 times 2 equals 19.68. So, you can also buy 2 magazines!

I hope this helps! Let me know if this is wrong. Thanks and have a nice day!

The original price of the Kindle is $269.99.

If the Kindle was 15% off, what is the discounted price of the Kindle?

Answers

It is now 229.46 dollars

Answer:

229.4915

Step-by-step explanation:

you first find 15% of $269.99 which is 15/100 * 269.99

which is 40.4915

and since you are finding the discounted price

you subtract 40.4915 from 269.99

= 269.99-40.4915

=229.4915

dont forget to put the unit ($)

=$229.4915

6x - 6y = 23  (Sub in the x with 8)

6(8) - 6y = 23

48 - 6y = 23  (Subtract each side by 48)

A store pays $365.84 for a fountain. The store marks up the price by 10%.
What is the amount of the mark-up?
Round your answer to the nearest cent: $

Answers

Answer:

The store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

Step-by-step explanation:

Given that a store pays $ 365.84 for a fountain, and then the store marks up the price by 10%, to determine the amount of the mark-up the following calculation must be performed:

365.84 x 10/100 = X

3,658.4 / 100 = X

36,584 = X

36.584 + 365.84 = 402.424

Thus, the store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

An angle measures 12°. Find its complement. Do not include units in your answer.

Answers

Answer:

78

Step-by-step explanation:

complements = 90

x + 12 = 90

-12. -12

× = 78

If two angles are complementary,

then the sum of their measures is 90 degrees.

If two numbers add to 90, we can represent those numbers as x and 90 - x.

So we will call one of our angles x and its complement as 90 - x.

So we have 90 - 12 which is 78.

So the complement of a 12° angle is a 78° angle.

Step-by-step explanation:

Answer:

How was Pi discovered?

Here's a brief history of finding π. The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for π, which is a closer approximation.

How is PI value calculated?

In some ways Pi (π) is a really straightforward number – calculating Pi simply involves taking any circle and dividing its circumference by its diameter. In fact if you search long enough within the digits of Pi (π) you can find any number, including your birthday.
