Mathematics

Answer: Only the second sequence is arithmetic. 

Work:
An arithmetic sequence is a sequence in which there is a common value added or subtracted between each term in the sequence. 
The first option, -2, 4, -6, 8,... is not arithmetic because the terms switch back and forth between positive and negative signs meaning that there is no common value that can be added between each term. 
The second option, -8, -6, -4, -2,... is arithmetic because there is a common difference between each term which is +2.
The third option, 2, 4, 8, 16,... is not arithmetic but is, in fact, geometric. There is no common value that is added or subtracted between each term.

Use pythagorean’s theorem
as you can see it’s a right isosceles triangle

so your equation is adapted to this:
p^2 + p^2=44^2
add like terms and simplify
2p^2=1936
divide by 2
p^2=968
square root
p= √968
simplify
p=22√2

the answer would be your second option

Approximately how many inches are in 2500 millimeters? Given 1 in = 2.54 cm, 1 ft = .3048 m, 1 mi = 1.61 km.
love history [14]
Let's begin with 2500 mm and convert this to cm.  

2500 mm = 250 cm

Next, convert 250 cm to inches.  Recall that 1 inch = 2.54 cm.

Then (250 cm)(1 inch) / (2.54 cm) = (250 cm) (1 in)/ (2.54 cm)

= (250/2.54) inches = ? inches

Answer:

C, x ≥ 14.96

Step-by-step explanation:

Step 1: Add 3.408 to both sides.

2.2x − 3.408 (+ 3.408) ≥ 29.504 (+ 3.408)

2.2x ≥ 32.912

Step 2: Divide both sides by 2.2.

2.2x (÷ 2.2) ≥ 32.912 (÷ 2.2)

x = 14.96
