Find an equation of a line through √3,1 / 2) parallel to the line:
a. x = −9
b. y = −√7
c. what can you conclude about your answer in parts (a) and (b)?

(a)

(b)

(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is which is parallel to x axis

Step-by-step explanation:

We have given points are

(a) Equation of line is given x = -9

We have to find the equation of line parallel to x= -9 and passing through

x = -9 line is parallel to y axis and so slope will be infinite

Equation of line is given by

So

(b) Equation of line is given

This line is parallel to x axis so slope will be zero

So equation of line will be

(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is which is parallel to x axis

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)
