Sid wants to find the height of a tree without having to climb it, but it is a cloudy day so he cannot use the shadows . he takes a mirror from his pocket and places it on thr ground 7.2m from the base of a tree. he backs up until he can see the top of the tree in the mirror, a distance of 1.2m from the mirror. if sids eyes are 1.5m above the ground what is the height of the tree?

Height of the tree is 9 m.

Step-by-step explanation:

Since we have given that

Distance at where he takes a mirror and placed it on the ground from the base of the tree = 7.2 m

Length of the tree from the mirror = 1.2 m

Distance at which he side eyes are above the ground = 1.5 m

Since there is direct variation between the actual height and the height in the mirror.

Let the height of the tree be h.

According to question,

Hence, height of the tree is 9 m.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
