Write an explicit formula for an , the nth term of the sequence 29, 19, 9, ....
Anna35 [415]

Answer:

a_{n} = 39 - 10n

Step-by-step explanation:

There is a common difference between consecutive terms , that is

19 - 29 = 9 - 19 = - 10

This indicates the sequence is arithmetic with nth term ( expicit formula )

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 29 and d = - 10 , then

a_{n} = 29 - 10(n - 1) = 29 - 10n + 10 = 39 - 10n

Suppose r varies directly with the square of m and inversely as s. If r= 12 when m = 6 and s=4, find r when m = 4 and s 10
zalisa [80]

Answer:

r=\frac{32}{15}

Step-by-step explanation:

If r varies directly with the square of m and inversely as s,

then r=\frac{km^2}{s} where k is some constant

Given r = 12 when m = 6 and s = 4:

       r=\frac{km^2}{s}

⇒    12=\frac{k6^2}{4}

⇒ \frac{12\times4}{6^2} =k

⇒     k = \frac{4}{3}

Therefore, substituting the found value of k into the original equation: r=\frac{4m^2}{3s}

Find r when m = 4 and s = 10:

   r=\frac{4m^2}{3s}

⇒ r=\frac{4\times4^2}{3\times10}

⇒ r=\frac{32}{15}
