Answer:
6 cubes.
Step-by-step explanation:
By looking at the picture attached we find that the only cubes that will have only once face painted are the ones located in the middle. The cubes near to the edge will have at least two faces painted.
Given that a cube has 6 faces, we can conclude that only 6 small cubes will have one face painted.
Answer:
49030
Step-by-step explanation:
we multiply it by ten so
4903×10=49030
The order of magnitude is essentially the number of powers of 10, which means that numbers 1-10 have an order of magnitude 1.
Then numbers 11-100 have an order of magnitude 2.
Then numbers 111-1000 have an order of magnitude 3.
Then numbers 1111-10000 have an order of magnitude 4.
Then numbers 11111-100000 have an order of magnitude 5.
And our number is in the last part! so the answer is "5".
Answer:
Step-by-step explanation:
symmetry with respect to y-axis for y=f(x) means f(-x)=f(x)
in this case, y = f(x) = x / (x^2+4)
f(-x) = -x / ((-x)^2+4) = -x / (x^2+4) = -f(x)
so it is not symmetric to y-axis
symmetry with respect to x-axis for x=g(y) means g(-y)=g(y)
in this case, y = x / (x^2+4)
y*(x^2+4) = x
y*x^2 + 4y - x = 0
substitute -y into g(y)
(-y)*x^2 +4(-y) - x = 0
-y*x^2 - 4y - x = 0
y*x^2 + 4y + x = 0
so g(-y) is not equal to g(y)
so it is not symmetric to x-axis
