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%.

an aeroplane is flying with a help of 300 km per hour who much distance will it cover in 160 minute ​
uysha [10]

Answer:

800 km

Step-by-step explanation:

Does the plane have a speed of it's own?  I don't see it, so will assume the plane is simply travelling at 300 km/h.

(300 km/hr)*(1 hr/60 min) = 5 km/min

(5 km/min)*(160 min) = 800 km in 160 minutes

Lindsey found a cupcake and weighed it on a digital scale. The cupcake weight 0.35 lb. what is the weight of the Rock in expande
SVEN [57.7K]

The weight of the cupcake in an expanded form is 3.5 * 10⁻¹ lb

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

The weight is given as:

Weight = 0.35 lb

Remove the unit

Weight = 0.35

Multiply the weight by 1

Weight = 0.35 * 1

Express 1 as 10/10

Weight = 0.35 * 10/10

Evaluate the product

Weight = 3.5 * 1/10

Express 1/10 as an exponent

Weight = 3.5 * 10⁻¹

Return the unit

Weight = 3.5 * 10⁻¹ lb

Hence, the weight in expanded form is 3.5 * 10⁻¹ lb
