Without considering the sign:
It's sigma(1 to 5, 5k+2)
Since the first item is minus, you simply add (-1)^k
So it's sigma(1 to 5, (-1)^k * (5k+2)
I choose A
Answer:
B
Step-by-step explanation:
A. (1.5)2 = 3 which is rational.
B. Root of 41 cannot be expressed as a fraction of p/q, where p and q are integers and q not equal to 0.
C. Root of 49 = 7 which is rational.
D. 15(2) = 30 which is rational
V = 130 mL
m = 0.250 lb = 113.398 g
Density: d = m/V
d = 113.398 g / 130 mL
d = 0.8722923 g / mL
the coordinates are (-2,1) (-2,-3) that is the answer
The answer would be either:
-99/10 or -9 9/10
