Population a current census shows that the population of a city is 3.5 million using the formula p= aert find the expected population of the city in 30 years of the growth rate r of the population is 1.5% a reaper prevents the current population in millions and the t represents the time in years

Answers

Answer 1
Answer:

Answer: the expected population of the city in 30 years is 5470781

Step-by-step explanation:

The population growth is exponential. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 3.5 × 10^6

r = 1.5% = 1.5/100 = 0.015

t = 30 years

Therefore,

A = 3.5 × 10^6(1 + 0.015)^30

A = 3.5 × 10^6(1.015)^30

A = 5470781

His speed was 2x² + 7x - 11 as he walked against the moving walkway.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

We are given that Carlos is walking on a moving walkway. His speed is given by the function

C(x) = 3x² + 3x - 4,

The speed of the walkway is W(x) = x² - 4x + 7.

The total speed as he walks along the moving walkway is;

x² - 4x + 7+ 3x² + 3x - 4,

= 4x² - x + 3,

Given Carlos turned around because he left his cell phone at a restaurant.

If he walked against the moving walkway

- x² + 4x - 7 + 3x² + 3x - 4,

2x² + 7x - 11

Well, for 20 you just add them, to get 4x^2-x+3. For 21, you do a substraction: 2x^2+7x-11. It'd take him quite some time (does this one even have zeros? :)) )

Solve the equation for P: xp+yp=z (literal equation)

Answers

If you would like to solve the equation xp + yp = z for p, you can do this using the following steps:

xp + yp = z
(x + y) * p = z
p = z / (x + y)

The correct result would be p = z / (x + y).

Which is more?
1. Riding a bike 10 miles in 1 hour
2. Jogging 3 miles in 24 minutes

Answers

I say that number one is more reasonable  but 10 miles in one hour, compared to 3 miles in 24 minuets 
and 3*3 = 9 
which is close to ten and 
24 * 3 = 72 minuets 
there are 60 minuets in an hour
so i would say the second option is correct :)
