= 12 + (- 6)(n - 1 )
This is an arithmetic sequence with n th term
= + (n - 1)d
here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and = 12, hence
= 12 + (- 6)(n - 1)
use this formula to find the 30 th term
= 12 + (- 6 × 29) = 12 - 174 = - 162
Answer:
Step-by-step explanation:
We are given the following in the question:
We have to find the growth rate z(t) in each of the following cases:
(a) z = xy
(b) z=x/y
(c) z=y/x
(d) z=x^(1/2) y^(1/2)
(e) z=(x/y)^2
(f) z=x^(-1/3)y^(2/3)
Answer:
answer for angle acb is 180 -90=2x and is 45
sory if I am wrong
X- 10=-2
X-4=4
Hop that helps
Step-by-step explanation:
John ran 3 miles this week.
Jane ran 10 times as far as John this week :
10×3 = 30 miles
but she ran this week 8 fewer miles than last week. in other words, last week she ran 8 miles more than this week :
30 + 8 = 38 miles.
so, last week she ran 38 miles.
