Answer:
triangles are half a rectangle/square. So thats why you divide by 2. diving by 2 is also multiply by 1/2.
pyramids are in 3 dimensions, so since they are like half, but in three dimensions, you divide by 3, in other words multiply by 1/3.
Step-by-step explanation:
The first thing we are going to do for this case is to rewrite the function.
We have then:
y = 3 ^ (2x)
We evaluate the points:
For (1,9):
y = 3 ^ (2 * 1)
y = 3 ^ (2)
y = 9
The point belongs to the function.
For (1/2, 3):
y = 3 ^ (2 * (1/2))
y = 3 ^ (1)
y = 3
The point belongs to the function.
For (-1, -9):
y = 3 ^ (2 * (- 1))
y = 3 ^ (- 2)
y = 1/9
The point does NOT belong to the function.
Answer:
The point (-1, -9) DOES NOT belong to the function.
Answer:
14 squares
Step-by-step explanation:
1. We know if the mosaic is a square shape, all sides are the same length and consist of the same amount of squares
2. Area is L×W, so in this case A×A=196
3. We can test this by replacing A with 14 and seeing if the answer is correct.
4. 14×14=196 is true
This can also be done by finding the square root of 196.
28800
4 meters=1 second
240 meters=60 seconds
240 meters per minute
x60
14400(per hour) x2=28800 in 2 hours
