Answer:
Step-by-step explanation:
a1 = 8
a9 = 56
Using formula for finding nth term of arithmeric sequence
We have to find 24th term, therefore n = 24
is the first term but we are missing d
d is the difference between the two consecutive terms, lets calculate it first
a9 = 56
Using the above given formula for finding d
put n = 9, a9= 56
56 = 8 + 8d
8d = 48
d = 6
Getting back to main part of finding 24th term
n = 24, d = 6, a1 = 8
put values in nth term formula
Answer:
first option
Step-by-step explanation:
number of shirts = x
price of shirts made = 9x+20
amount u earn by selling the shirts = 15x
profit = 15x - (9x+20)
profit of at least 150,
15x - (9x+20) ≥ 150
On the right side, there are
• 2•2 = 4 atoms of Nb
• 2•5 = 10 atoms of O
so among the reactants on the left, the reaction is balanced as
4 Nb + 5 O₂ → 2 Nb₂O₅
There are 3
the number 5 number 3 and 2
Regroup:
(x^4+2x^2-8)-(x^3+4x)=0
Factor: (x^2-2)(x^2+4)-x(x^2+4)=0
both terms have (x^2+4), so (x^2+4)(X^2-x-2)=0
factor again: (x^2+4)(x+1)(x-2)=0
x=1, x=2, x=2i, or x=-2i
