An integer is close to zero if it is "small".
By small, we mean that it is small in absolute value. In fact, for any given distance
, there are two integers that are
units away from zero:
and
.
So, for example, -6 is close to zero than 8, because -6 is six units away from zero, while 8 is eight units away from zero.
So, the answer is B, -8, because it is 8 units away from zero. The other options A, C and D are, respectively, 12, 10 and 14 units away from zero.
I don't know if we can find the foci of this ellipse, but we can find the centre and the vertices. First of all, let us state the standard equation of an ellipse.
(If there is a way to solve for the foci of this ellipse, please let me know! I am learning this stuff currently.)

Where

is the centre of the ellipse. Just by looking at your equation right away, we can tell that the centre of the ellipse is:

Now to find the vertices, we must first remember that the vertices of an ellipse are on the major axis.
The major axis in this case is that of the y-axis. In other words,
So we know that b=5 from your equation given. The vertices are 5 away from the centre, so we find that the vertices of your ellipse are:

I really hope this helped you! (Partially because I spent a lot of time on this lol)

There are 130 centimeters in 1.3 meters
Answer:
A.
Step-by-step explanation:
I think it makes the most sense sorry if i got it wrong
2. an=20+an−1 and a1=145
she starts with 145 so a1=145 and then adds 20 every month: an=20+an−1
