In 2014, the population of India1 was 1.236 billion people and increasing at a rate proportional to its population. If the popul

ation is measured in billions of people and time is measured in years, the constant of proportionality is 0.0125. Define P to be the population of India, in billions of people, in the year t, where t represents the number of years since 2014.

Answer:

P = 1.236 * (1.0125)^t

Step-by-step explanation:

As the Population increases at a rate proportional to itself, this is an exponencial growth, so we can write the following formula:

P = Po * (1+r)^t

where P is the population after t years, Po is the inicial population (at t=0), r is the rate of growth and t is the amount of time in years.

For our problem, we have that Po = 1.236 and r = 0.0125.

Finally, we can write the equation for P:

P = 1.236 * (1.0125)^t

How do I solve this?
andreev551 [17]

Answer:

x is in the range [-1,4]

Step-by-step explanation:

I haven't worked with absolute value inequalities in awhile, but let's take a wack at this.

We are given the following inequality:

| 2x - 3 | <= 5

This implies two possible cases:

[1] -5 <= 2x -3

Or

[2] 2x - 3 <= 5

So let's solve x for both of these cases:

[1] -5 <= 2x - 3

 -2 <= 2x

 -1  <= x

[2]  2x - 3 <= 5

 2x <= 8

  x <= 4

So from these cases, we can say the following is true:

x >= -1  and x <= 4

Thus, we can write this in the form

-1 <= x <= 4

Or in interval notation:

{ x is element of reals | -1 <= x <= 4}

Also written as

x is in the range [-1,4]

Where the closed brackets represent 1 and 4 as possible answers whereas parenthesis would imply they were not.

Cheers.

The perimeter of this kite is 108 cm.
taurus [48]

Answer:

n is equal to 26

Step-by-step explanation:

Equation: n+ n + (n+2) +(n+2) = 108

so: 2n + 2(n+2) = 108

2n + 2n + 4 = 108

4n + 4 = 108

4n = 108 - 4

4n = 104

n = 104/4

n = 26
