What exponent would complete this equation 0.005 = 5 x 10? To the ? Power
1 answer:
Answer:
-3
Step-by-step explanation:
0.005 = 5 *
0.005 = 5 * 0.001
Thus, to find what 10 should be raised to, we should find which exponent of 10 gives us 0.001
We can do this by just testing a few numbers from 10^1 and down:
As we can see, = 0.001, thus the exponent in our equation is -3
A shorthand of this is counting the number of zeroes, 10^-1 has one zero, 10^-2 has two zeroes, and 10^-3 has three zeroes.
Since we were looking for 0.001, which has 3 zeroes, we can see that the correct exponent should be -3.

Answer:
The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.
If the function has a positive leading coefficient, the vertex corresponds to the minimum value.
If it has a negative leading coefficient, the vertex corresponds to the maximum valuevalue
If the vertex is located at
(–2, 0)
The possibilities are
y = (x-2)^2
or,
y = - (x-2)^2
Since the problem tells us the answer, we adopt the positive values
Answer:
y = (x-2)^2
