The sum of 5 consecutive odd numbers is 145.<br><br><br> What is the third number in this sequence?
Marina86 [1]
The answer is 29 

let n be the first of the consecutive odd numbers
⇒ n, n+2, n+4 n+6, n+5
represent 5 consecutive odd numbers
sum = n+ (n+2) + (n+4) + (n+6) + (n+8) = 5n+20
⇒ 5n +20=145 
Solve for n = 25

25, 27, 29, 31, 33

25+27+29+31+33=145

Vf²=vi²+ 2ad <br><br> A) solve for vi<br><br> B) solve for d <br><br> Using the same equation
diamong [38]
A)
               Vf² = vi² + 2ad   Subtract 2ad from both sides
     Vf² - 2ad = vi²              Find the square roots of both sides
√(Vf² - 2ad) = √(vi²)         Cancel out the squares with the square roots
  Vf - √(2ad) = vi               Switch the sides to make it easier to read
                 vi = Vf - √(2ad)

B)                 Vf² = vi² + 2ad   Subtract vi² from both sides
             Vf² - vi² = 2ad           Divide both sides by 2a
    (Vf² - vi²) / 2a = d               Switch the sdies to make it easier to read
                         d = (Vf² - vi²) / 2a

Please helpppppppppp
GaryK [48]

Answer:

D

Step-by-step explanation:

Count the number of places it takes to get one place past  3

There are 5 zeros in the given question. That gets you to just before the 3.

Add one more to get past the 3. That makes 5 zeros + 1 more place = 6

Since you are moving right, the 6 is minus. Your answer is 3 * 10^-6
