Answer:

1380 people.

Step-by-step explanation:

We have been given that population density is the number of people per unit of area.

\text{Population density}=\frac{\text{Number of people}}{\text{Area}}

\frac{\text{60 people}}{\text{ km}^2}=\frac{\text{Number of people}}{23\text{ km}^2}  

\frac{\text{60 people}}{\text{ km}^2}*23\text{ km}^2=\frac{\text{Number of people}}{23\text{ km}^2}*23\text{ km}^2

\text{60 people}*23=\text{Number of people}

1380\text{ people}=\text{Number of people}

Therefore, the population of the region would be 1380 people.

If a, b, 72, (a+b) are consecutive terms of an A.P., find the values of a and b.​
mel-nik [20]

Answer:

a = 36, b = 54

Step-by-step explanation:

Since the terms are in arithmetic progression then there is a common difference d between consecutive terms , that is

b - a = 72 - b ( add b to both sides )

2b - a = 72 → (1)

and

a + b - 72 = b - a ( subtract b - a from both sides )

2a - 72 = 0 ( add 72 to both sides )

2a = 72 ( divide both sides by 2 )

a = 36

-------------

Substitute a = 36 into (1) and evaluate for b

2b - 36 = 72 ( add 36 to both sides )

2b = 108 ( divide both sides by 2 )

b = 54

-----------------

Thus a = 36 and b = 54

The sequence is therefore 36, 54, 72, 90 , .....

F(x) = -0.5x2, if f(x) = -112.5, what is the value of 'x'?<br> ?
sleet_krkn [62]

Answer:

x = ± 15

Step-by-step explanation:

Given f(x) = - 0.5x² and f(x) = - 112.5 , then equate right sides

- 0.5x² = - 112.5 ( divide both sides by - 0.5 )

x² = 225 ( take square root of both sides )

x = ± \sqrt{225} = ± 15

Three consecutive integers add up to 51. What are these integers​
kaheart [24]

Let the three consecutive integers be x, x+1 and x+2.

According to the question, x+x+1+x+2=51

=>3x+3=51

=>3x+3-3=51-3

=>3x=48

=>x=16

Hence, first integer = 16,

second integer = 16 + 1 = 17 and

third integer = 16 + 2 = 18.
