Answer:

Current water in dam = 1,676.202 million m³ (Approx.)

Step-by-step explanation:

Given:

Storage capacity of dam = 2,536 million m³

Current water level = 65.4%

Find:

Current water in dam

Computation:

Current water in dam = Storage capacity of dam x Current water level

Current water in dam = 2,563 x 65.4%

Current water in dam = 1,676.202 million m³ (Approx.)

a/b = 6

36/b = 6

6b = 36

b = 36/6 = 6

b/x = 36

6/x = 36

36x = 6

x = 6/36 = 1/6

Answer:

$f(x)=5120(5)^{x}$

Step-by-step explanation:

From the image, f(x) and x are rlated by

$f(x)=a( {b})^{x}$

where b is the common ratio

We first find the value for b

$\frac{6400}{5120}= 5$

$\frac{8000}{6400}= 5$

$\frac{10000}{8000} = 5$

$\frac{12500}{10000} = 5$

$\frac{15625}{12500}=5$

so we can say the common ratio, b=5

we put in any value of f(x) and the corresponding value for x to find a value

Let put x=0 and f(x)=5120

This implies that

$5120 = a(5)^{0}$

but

$5^{0} = 1$

Hence a=5120

Thus the equation which model the relationship between the weeks and the viewers is

$f(x)=5120(5)^{x}$
