For each graph find (a) AB to the nearest tenth and (b) the coordinates of the midpoint of line AB

Mathematics

In each graph, they give you a line.

For part A, they want you to use the <u>Distance Formula</u> which is:

\sqrt{(x2 - x1)^{2}+(y2 - y1)^{2}}

(x2 is supposed to be x sub 2, but I can't put subheadings in the equation tool)

x1, x2, y1, and y2 are the coordinates of the endpoints of the segment.


For part B, they want you to use the <u>Midpoint Formula</u>, which is:

(\frac{x1 + x2}{2}, \frac{y1 + y2}{2})

The coordinate pair you get from the Midpoint Formula is your midpoint.


Hope this helps! :)

Answer:

Step-by-step explanation:

1a+1b(a+b-c)+1b+1c(b=c-a)+ 1a+1c(c+a-b)

1a+1b-c+1b +1c-a+1a+1c-b

1a+2b-c+a+1c-b

2a+1b+c this is the answer I think lol

Viktor [21]

<u>Given:</u>

The angle of elevation from the point on the ground to the top of the tree is 34° and the point is 25 feet from the base of the tree.

We need to determine the height of the tree.

<u>Height of the tree:</u>

Let the height of the tree be h.

The height of the tree can be determined using the trigonometric ratio.

Thus, we have;

tan \ \theta=\frac{opp}{adj}

Substituting the values, we get;

tan \ 34^{\circ}=\frac{h}{25}

Multiplying both sides by 25, we have;

tan \ 34^{\circ} \times 25=h

 0.6745 \times 25=h

       16.8625=h

Rounding off to the nearest tenth of a foot, we get;

16.9=h

Thus, the height of the tree is 16.9 feet.

Hence, Option B is the correct answer.
