Answer:

7/24

Step-by-step explanation:

you have to have a common denominator so you multiply one denominator to the opposite numerator and denominator and vice versa. So for 2/3 you should get 16/24 and for 3/8 you should get 9/24. Then you subtract 9 from 16 and get 7. So the answer is 7/24

In the notation "t(x) =...," what does "t(x)" represent?
Tasya [4]

Answer:

The value of t(x) depends on the value of x, since t  is a function of x.

Step-by-step explanation:

In any function of the form "t(x)=...," the term "t(x)" represents the output value, while x represents the input value. So, the notation "t(x)=...," indicates that the value of t(x) depends on the value of x, since t is a function of x.

A countries population in 1991 was 147 million. In 1998 it was 153 million. Estimate the population in 2017 using the exponentia
scoundrel [369]

Answer:

The population in 2017  is 171 million

Step-by-step explanation:

Let's assume population starts from 1991

so,

initial population is 147 million

so, A=147

we can use formula

P=Ae^{kt}

we can plug A=147

P=147e^{kt}

In 1998:

t=1998-1991=7

P=153

now, we can plug these values into formula and find k

153=147e^{7k}

Divide both sides by 147

\frac{147e^{7k}}{147}=\frac{153}{147}

e^{7k}=\frac{51}{49}

\ln \left(e^{7k}\right)=\ln \left(\frac{51}{49}\right)

k=\frac{\ln \left(\frac{51}{49}\right)}{7}

k=0.00572

now, we can plug it back

and we get

P=147e^{0.00572t}

In 2017:

t=2017-1991=26

we can plug it and find P

P=147e^{0.00572\times 26}

P=170.57

So,

The population in 2017  is 171 million
