Is the following statement a good definition? Why? An integer is divisible by 100 if and only if its last two digits are zeros.

nikitadnepr [17]

The given statement is An integer is divisible by 100 if and only if its last two digits are zeros.

The two conditional statements that can be made are:

1) If an integer is divisible by 100 its last two digits are zeros.

This is a true statement. If a number is divisible by 100, it means 100 must be a factor of that number. When 100 will be multiplied by the remaining factors, the number will have the last two digits zeros.

<h3>What happen when last two digit of the number are 0?</h3>

2) If the last two digits of an integer are zeros, it is divisible by 100.

This is also true. If the last two digits are zeros, this means 100 is a factor of the integer. So the number will be divisible by 100.

Therefore, the two conditional statements that are formed are both true.

So, option A is the correct answer.

Yes, it is. When the definition is separated into two conditional statements, both of the statements are true.

What's 2sin(2theta)=1? Need it for webassign.

lutik1710 [3]

<em>Solve: </em> $2sin(2x) = 1$

Divide both sides by 2.
$sin(2x) = \frac{1}{2}$

Take the sine inverse of both sides:
$2x = sin^{-1}(\frac{1}{2})$
$2x = \frac{\pi}{6}, \frac{5\pi}{6}, 0 \leq x \leq 2\pi$
$x = \frac{\pi}{12}, \frac{5\pi}{12}$

But we know there are more solutions if we extend the domain. In fact, there are infinitely more solutions since the domain of sine is all real x values.
Thus, we can develop a general solution:

For every $\pi$ units, there is another solution for both $\frac{\pi}{12}$ and $\frac{5\pi}{12}$

General solutions:
$x = \pi n + \frac{\pi}{12}, n \in \mathbb{Z}$
$x = \pi n + \frac{5\pi}{12}, n \in \mathbb{Z}$

Find the first six terms of the sequence.

shutvik [7]

A1 = -7, an = 4(an - 1)
a2 = 4a1 = 4(-7) = -28
a3 = 4a2 = 4(-28) = -112

Therefore, the first six terms are -28, -112, -448, -1792, -7168, -28,672
