Step-by-step explanation:
These are the terms of a geometric sequence with n th term
= a
where re a is the first term and r the common ratio
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3 ← common ratio
and a = - 3, thus
[te x]a_{n}[/tex] = - 3
← explicit formula
Based off of what I can see in the photo (its too blurry to know for sure) and what I think you're asking:
The angle of a triangle always adds up to 360degrees, so base it on that and the acute and obtuse angles and get the degrees from there, the angle would be those degrees you find or <10, 5, 4 (what I assume is a 5)
Given that <span>C = { X | X + 6 = 10}
This can be interpreted grammatically as "C is a set X such that X is the solution to X + 6 = 10".
Given that X + 6 = 10
X = 10 - 6 = 4
Therefore, the solution is
C = {4}

Answer:
$1380
Step-by-step explanation:
- The regular price of a computer is $1200
- The regular price of a printer is $300.
The electronics store offers a 40% discount on the printer only when the computer is purchased at the regular price.
Discount on the Printer = 40% of $300 =0.4 X 300 =120
Promotional Price of the Printer = $300-120 =$180
Therefore, the total cost of the computer and the printer at the promotional price
=Regular price of a computer + Promotional Price of the Printer
=1200+180
=$1380
