What is the distance between (-2, 6) and (-2, -1)

7 units

Step-by-step explanation:

(-2,6)=(X1,Y1)

(-2, -1)=(X2,Y2)

now ,

distance=√{(x2-x1)^2+(y2-y1)^2}

=√{(-2+2)^2+(-1-6)^2}

=√49

=7 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)
