Answer:
The mapping can also be represented as the set of ordered pairs: (4, 9) (5, 10) (6, 11) (7, 12). The ordered pair preserves the directional property of the relation. It is consistent with the order of points plotted on a Cartesian Plane represented by (",$). In the Arrow Diagram that follows.
Step-by-step explanation:
It does not look like Suro even made an error. She took the square root of both sides to get x = 7, I don't see any problem here.
Answer:
853
Step-by-step explanation:
u have 20HP
u dead
For this one, just do 240 divided by 60 to get 3, which means it will take him 3 hours if he drives at a constant speed of 60mph.
Answer:
The radius of the base of the small cone is 3 feet
Step-by-step explanation:
The question requires the determination of the radius of the smaller cone
Therefore, height of the larger cone = 10 feet
Base diameter of the larger cone = 10 feet
Height of horizontal plane of small plane above base of larger cone = 4 feet
Hence the height of the small cone = 6 feet
Therefore, by similar triangles, and tangents we have;

Where:
x = The diameter of the base of the small cone
Therefore;

The radius of the base of the small cone = half the diameter of the base of the small cone
∴ The radius of the base of the small cone = (6 feet)/2 = 3 feet.
