Aperson is 1.9 m tall. where should he place the top of a mirror on the wall so he can see the top of his head? assume his eyes are 4.8 cm below the top of his head. find a minimal vertical distance from the level of the person’s eyes to the top of the mirror.

0.024 meters

Step-by-step explanation:

The height of the person = 1.9 m

Assume his eyes are 4.8 cm below the top of his head.

So, the person should place the top of mirror at a distance of :

 cm

And in meters it is : 0.024 meters

The minimal vertical distance from the level of the person’s eyes to the top of the mirror is 0.024 meters.

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
