Write an
explicit formula for An, the nth term of the sequence 15, 8, 1,

b(n) = 15 - 7(n - 1)

Step-by-step explanation:

15 is the y-intercept

-7 is the slope

= 22 - 7n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

8 - 15 = 1 - 8 = - 7

This indicates the sequence is arithmetic with explicit formula

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 15 and d = - 7 , then

= 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
