Part 1 out of 2 Select the real-world problem best represented by the equation 15x = 570. A An elephant walks with a speed of 15
nika2105 [10]

Answer:

Option A.

Step-by-step explanation:

We will check each option given in the question.

Option A. If an elephant walks with the speed = 15 steps a minute

If it takes x hours to cover 570 steps then the expression should be

15x = 570

Therefore, Option A. will be the answer.

Option B. A giraffe eats leaves = 570 per hour

If it eats for 15 hours then number of leaves eaten by giraffe = 570×15

So the expression is not formed.

Therefore, Option B is not the answer.

Option C. Dandelions eaten by the donkey = 15

and dandelions eaten by cow = 570

So total dandelions eaten by cow and donkey together = 15 + 570

Again the expression is different so Option C is incorrect

Option D. A Canary flew for 15 hours towards north, then turned east and flew for 38 hours.

Here speed of the canary is not mentioned so it's not possible to form any expression for the distance covered by the canary.

Therefore, Option D is also incorrect.

Option A. is the answer.

The number of users on a website is 630 and is growing exponentially at a rate of 76% per year. Write a function to represent th
Dafna1 [17]

The exponential function that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

The daily rate of change is of 20.82%.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

For this problem, the parameters are given as follows:

A(0) = 630, r = 0.76

Hence the equation that represents the number of users on the website after t is given by:

A(t) = 630(1.76)^t

An year has 365 days, hence the rate of change per day is given by:

76/365 = 0.2082 = 20.82%.

The daily rate of change is of 20.82%.
