The horizontal line segment at the top of the polygon on the grid below is how many units long?

Ymorist [56]

Answer:

6 units long.

Step-by-step explanation:

Given:

A polygon drawn on a graph.

In order to determine the distance of the horizontal line at the top, we find the coordinates of the end points and then use distance formula to find the exact distance.

Let us label the polygon as ABCD as shown below. AB is the length of the horizontal line.

Coordinates of A are $(x_1,y_1)=(-3, 4)$ as seen in the graph.

Coordinates of B are $(x_2,y_2)=( 3, 4)$ as seen in the graph.

Now, distance formula for two points $(x_1,y_1)\ and\ (x_2,y_2)$ is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d_{AB}=\sqrt{(3-(-3))^2+(4-4)^2}\\d_{AB}=\sqrt{(3+3)^2+0}\\d_{AB}=\sqrt{36}=6\ units$

Therefore, the horizontal line at the top is 6 units long.

The winner of a 200 mile race drove his car to victory at a rate of 140.2159 mph. What was his time (to the nearest thousandth

Keith_Richards [23]

Answer: 1.43 h

Step-by-step explanation:

Velocity is $V$ is defined as the change in position (displacement) $d$ of an object in a specific time $t$ :

$V=\frac{d}{t}$

Where:

$V=140.2159 mi/h$ is the car's velocity

$d=200 mi$ is the distance the winner car traveled

$t$ is the time

Isolating $t$ :

$t=\frac{d}{V}$

Solving with the given information:

$t=\frac{200 mi}{140.2159 mi/h}$

$t=1.426 h \approx 1.43 h$ This is the winner's time
