VARVARA [1.3K]

Answer:

yes, (0,0) is a solution for the system of equations.

Step-by-step explanation:

y < -x + 3 ,we would then plug in the ordered pair which changes that equation to 0 < 0 +3 (which is just 0 < 3) and that is true.

Then we plug in the ordered pair for the second equation, which changes it to  0 < 2 or 0 < 0 + 2.

Now, since the inequalities are true, the ordered pair works for the system.

(sorry if that was confusing)

Fudgin [204]

Answer:

A) In 2004 the population will reach 306 million.

B) In 2033 the population will reach 386 million.

Step-by-step explanation:

Given : The population of a certain country in 1996 was 286 million people. In​ addition, the population of the country was growing at a rate of 0.8​% per year. Assuming that this growth rate​ continues, the model P(t) = 286(1.008 )^{t-1996} represents the population P​ (in millions of​ people) in year t.

To find : According to this​ model, when will the population of the country reach A. 306 million? B. 386 million?

Solution :

The model represent the population is P(t) = 286(1.008 )^{t-1996}

Where, P represents the population in million.

t represents the time.

A) When population P=306 million.

306 = 286(1.008 )^{t-1996}

\frac{306}{286}=(1.008 )^{t-1996}

1.0699=(1.008 )^{t-1996}

Taking log both side,

\log(1.0699)=\log((1.008 )^{t-1996})

\log(1.0699)=(t-1996)\log(1.008)  

\frac{\log(1.0699)}{\log(1.008)}=(t-1996)  

8.479=t-1996  

t=8.479+1996

t=2004.47

t\approx2004

Therefore, In 2004 the population will reach 306 million.

B) When population P=386 million.

386 = 286(1.008 )^{t-1996}

\frac{386}{286}=(1.008 )^{t-1996}

1.3496=(1.008 )^{t-1996}

Taking log both side,

\log(1.3496)=\log((1.008 )^{t-1996})

\log(1.3496)=(t-1996)\log(1.008)  

\frac{\log(1.3496)}{\log(1.008)}=(t-1996)  

37.625=t-1996  

t=37.625+1996

t=2033.625

t\approx2033

Therefore, In 2033 the population will reach 386 million.
