The area of a triangle is determined by the formula: Base x Height * 1/2
You'll need to assign a base to the triangle. Based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). The distance between any two numbers is found by just subtracting them. Here, you should subtract the x values to find the distance of this side.
2 - (-2) = 4.
So the distance (aka the length of the base) is 4. The height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). We should subtract the y values this time to find the height/distance.
4 - 1 = 3
So the height is 3.
Base = 4
Height = 3
Answer:
Angle 2 is 36 degrees
Step-by-step explanation:
73 - 37 = 36
Answer:
vvvvvvvvvvvvvvvvv
Step-by-step explanation:
vvvvvvvvvvvvvvvv
The answer is D. All you have to do is graph the equation, and you will have the vertex and the roots. By the way, you can rule out B and C because those two do not follow the rules of a quadratic. Also, A and B have the wrong axis of symmetry, because the rocket lands after 10 seconds.
To work out 7% of 600, this is what you do
7/100 x 600
this will give you your answer
7% of 600 = 42
