1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

The population of a suburb is 4000 people. The, №17886261, 02.11.2022 20:00

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

The population of a suburb is 4000 people. The, №17886261, 02.11.2022 20:00

So, if d = -2, then the population of the suburb is equal to 1000.

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

P=4000\times 2^d

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000

So, if d = -2, then the population of the suburb is equal to 1000.

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Let the father's age be x and son's be y

10 years before-

Father age=x-10

sons age=y-10

Given,

x-10=10(y-10)

x-10=10y-100

Given present age of father=40

therefore,

x=40

40-10=10y-100

10y-100=30

10y=130

y=130/10

y=13

Therefore present age of son=13years
