Answer:

(-1373)

Step-by-step explanation:

a = 1st term = -13

Common difference = d = 2nd term - 1st term

d = -33 - (-13) = -33 + 13

d = -20

n = 69

nth term = a + (n-1)d

69th term = (-13) + 68 * (-20)

= -13 - 1360

= - 1373

What is the solution of the equation 3^5 sqrt (x+2)^3+3=27?

BlackZzzverrR [31]

3^5) (x + 2)^(3/2) + 3 = 27
(x + 2)^(3/2) = 24 / 243 
x + 2 = [ 24 / 243 ]^(2/3) 
x + 2 = [ 8 / 81 ]^(2/3) 
x = [ 4 / 81^(2/3) ] - 2 =-1.786

the answer is x=-1.786

Find the inverse of square root f(n) = n – 3.

pogonyaev

Answer:

$f'(n) = n + 3$

Step-by-step explanation:

Given

$f(n) = n - 3$

Required

The inverse

$f(n) = n - 3$

Replace f(n) with y

$y = n - 3$

Swap positions of y and n

$n = y - 3$

Make y the subject

$y = n + 3$

Replace y with f'(n)

$f'(n) = n + 3$
