Splitting the trapezoid into 2
triangles and a
we
can sum up the areas to find the area of the trapezoid. The area of each right triangle
is
square units. The area of the rectangle is
square
units. The area of the trapezoid is
square units.

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)

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
