What is the x-intercept of the function graphed below? A. (2,0)
B. (0,-4)
C. (0,2)
D. (-4,0)

9514 1404 393

  A.  (2, 0)

Step-by-step explanation:

The x-intercept is the point where the line crosses the x- (horizontal) axis. The coordinates there are (2, 0).

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
