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%.

6. Kriti has a circular swimming pool in her house. The radius of the swimming
Evgen [1.6K]

Answer:

Total walk she did around the pool every morning = 141.3

Step-by-step explanation:

Given - Kriti has a circular swimming pool in her house. The radius of the swimming  pool is 22.5 cm. She walks one round every morning before diving in the pool.

To find - How far does she walk around the pool every morning?

Proof -

Given that, the swimming pool is circular in shape.

So,

1 round of circle = Circumference of circle.

As we know that,

Circumference = 2\pi r

                         = 2*\pi *22.5

                         = 141.3

∴ we get

Total walk she did around the pool every morning = 141.3

if 7 men and 5 womean have applied for job and 3 applicants are randomly selected from the probability that 2 are men​
barxatty [35]

The  probability that 2 men are selected is 49/144

Probability is the likelihood or chance that an event will occur.

If 7 men and 5 women have applied for job, the total number of people that applied will be 12 people

  • Pr(2 men are selected) = 7/12 * 7/12
  • Pr(2 men are selected) = 49/144

Hence the  probability that 2 men are selected is 49/144
