Given: AB ⊥ l, B ∈ l, M ∈ AB , AM = 7 in, AB = 15 in. Find the distance between point M and line l.
elixir [45]

AB ⊥ l, B ∈ l, M ∈ AB , AM = 7 in, AB = 15 in.

Here AB is a line segment which is perpendicular to line I.

Point B lies on line I,and Point B lies on line segment AB.

⇒AB=15 [Given]

⇒AM+MB=15

⇒AM=7[given]

⇒7+MB=15

⇒MB=15-7

⇒MB=8in

So,the length of line segment MB is 8 in.

The same thing is depicted in the diagram.

Simplify the quotient 4.5 x 10^3/9 x 10^7 . Write your answer in scientific notation. Show your work.
astra-53 [7]
4.5*10^3/9*10^7=4.5/9*10^3*10^7=0.5*10^3*10^7. a^b*a^c=a^(b+c), so 10^3*10^7=10^(3+7)=10^10. 0.5*10^10=5*10^9, since we want to write in scientific notation where the leading number is bigger than one and smaller than 10.
