Answer:
The ball will bounce to 2.07 feet after 4th drop.
Step-by-step explanation:
Bradley dropped a ball from a roof 16 feet high. So, its the initial height.
Each time the ball hits the ground it bounces 3/5 the previous height.
Means after 1st drop, the ball will again rise to feet.
Similarly after 2nd drop, it will bounce to
After 3rd drop, it will bounce to feet
After 4th drop, it will bounce to feet
Hence, the ball will bounce to 2.07 feet after 4th drop.
Answer: 2.0736 ft
Step-by-step explanation:
Bounce 1: 16*3/5=9.6
Bounce 2: 9.6*3/5=5.76
Bounce 3: 5.76*3/5=3.456
Bounce 4: 3.456*3/5=2.0736
Answer:
The graph that represents a cubic function is:
Graph A.
Step-by-step explanation:
We know that for the graph of a cubic function it satisfies the property that:
Graph B:
It is a graph of a linear function.
Since a graph of a linear function is a straight line.
Graph C:
It is a graph of a quadratic function.
Since both the ends of the graph are in the same direction.
Graph D:
It is also a graph of a linear function.
As the graph is a straight line.
Graph A:
It is a graph of a cubic function.
Since it satisfies all the above properties.
An angle is defined as the figure, in which two rays meet at a common point called the vertex.
Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'. It is represented by the symbol ∠. Angles are usually measured in degrees and radians, which is a measure of circularity or rotation. In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle. Let us read about the different parts of an angle.
There are two main parts related to an angle - the arms and the vertex. Vertex is a common endpoint that is shared by the two rays. Observe the figure in which the vertex O is marked as the joining point of the two arms.
An angle is measured in degrees. One full rotation around a point forms a complete angle of 360°.
