Mazyrski [523]

Answer:

d = 10(1.03^t)
13 ft

Step-by-step explanation:

For t in weeks, a reasonable exponential function describing the dept (d) might be ...

d = 10(1.03^t)

Then, after 8 weeks, the depth is predicted to be ...

d = 10(1.03^8) ≈ 12.67 ft ≈ 13 ft

Maxim and Salma were asked to find an explicit formula for the sequence 54,63,72,81,... Maxim said the formula is f(n)=54+9n Sal

Sever21 [200]

ANSWER

The explicit rule is

$f(n) = 45+9n$

EXPLANATION

The given sequence is :

54,63,72,81,...

The first term of this sequence is

$a = 54$

The common difference is

$d =63 - 54 = 9$

The explicit rule is given by:

$f(n) = a + d(n - 1)$ $f(n) = 54+9(n -1 )$

We expand to get:

$f(n) = 54+9n -9$

$f(n) = 45+9n$

None of them is correct .
