An arithmetic sequence is shown below.
Elena L [17]

Answer:

B. a (n) = -3n + 13

Step-by-step explanation:

Given arithmetic sequence is: 10, 7, 4, 1, -2, ...

Here a = 10, d = 7 - 10 = - 3

a_n = a + (n - 1)d \\  \\ a_n = 10+ (n - 1)( - 3) \\  \\  a_n = 10 - 3n  + 3 \\  \\  \purple{ \bold{a_n =   - 3n  +1 3 }}\\  \\

Differentiate. <br><br> y = ln(t)/t²
azamat
Remember

the deritivive of f(x)/g(x)=(f'(x)g(x)-g'(x)f(x))/((g(x))^2)

deritivive of lnx is 1/x
derivitive of t^2=2t

so

\frac{(1/t)t^2-2tlnt}{(t^2)^2}=
\frac{t-2tlnt}{t^4}=
\frac{1-2ln(t)}{t^3}
