Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*
Veronika [31]

Answer:

<em>The area of the triangle DEF is 10.</em>

Step-by-step explanation:

<u>Area of a Triangle:</u>

A triangle of base B and height H (both must be perpendicular) has an area of:

\displaystyle A=\frac{BH}{2}

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

\displaystyle A=\frac{5*4}{2}=10

The area of the triangle DEF is 10.

I need help. The units of the definite integral are the units of the x-axis times the y-axis. So in a velocity (m/s) versus time
enyata [817]

Explanation:

The average value of the velocity function is the height of the rectangle that has the same area as the velocity curve. That height is still measured in m/s.

If you want to find distance traveled (in m), then you must multiply the height in m/s by the width in s.

Use the Counting Principle to find the probability of rolling a 4 on each of 3 number cubes
Dennis_Churaev [7]

Answer:

\frac{1}{216}

Step-by-step explanation:

We have been given that three cubes are being rolled and we are required to find the probability of getting 4 on each of the three cubes.

We know the probability of rolling a 4 on one cube will be \frac{1}{6}. Since there are 3 cubes, the probability of rolling 4 in each of the individual cubes will be \frac{1}{6}.

But we want 4 to be rolled on all three cubes at once, in order for that to happen, we need to get a four on first cube AND second cube AND third cube. Since there is AND between the events, we will multiplied their probabilities as per counting principle. Thus, the required probability of rolling 4 on each of the three cubes is \frac{1}{6}\cdot\frac{1}{6}\cdot\frac{1}{6} which simplifies to \frac{1}{216}.
