Answer:
8 by 9 over 7
Step-by-step explanation:
Use the quadratic formula with a = 2, b = -5, and c = 1
x = -b ± sq rt b2 - 4ac
-------------------- <---------- Please note: sq rt is over entire expression of b^2 - 4ac
2a
x = - (-5) ± sq rt (-5)2 + 4(2)(1)
-------------------------------- <---------Please note: sq rt is over entire expression (-5)2 + 4(2)(1)
2(2)
x = 5 ± √17
---------
4
x = 5 + 1√17 OR x = 5 + -1√17

4 4 4 4
Common difference in Arithmetic sequences is defined as the fixed amount <span>referring to the fact that the difference between two successive terms yields the constant value that was added. In order to know the common difference of the given sequence above, we just have to deduct 1/2 from 1/4 and the answer is -1/4. Therefore, the correct answer would be the third option. Hope this answer helps.</span>

Answer:
(c) 1/(36·a^4·b^10)
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)/(a^c) = a^(b-c)
(a^b)^c = a^(bc)
a^-1 = 1/a

Amy:
8 + 5 + 6 + 11 + 4 + 6 +8 = 48
48 divide by 7 = 6.85
chelsea:
7 + 9 + 5 + 3 + 10 + 5 + 8 = 47
47 divide by 7 = 6.71
amy runs more on average.
both mean !
