1) How much larger or smaller the image will be depends on the scale factor in a mathematical object's dilatation (compared to the original object). When the scaling factor's absolute value exceeds 1, an expansion takes place.

2) No. scale factors can’t be rational numbers. Scaling up always involves a scale factor larger than 1. Let's put this in the formula, which makes it: 15 5 = 3, for instance, if the larger figure's dimension is 15 and the smaller one's is 5. As a result, it is clear that the scale factor is higher than 1.

Answer:

Ah! Geometric sequences, Eh? Sucks I know....

Step-by-step explanation:

So first, we need to find the factor of this(been a while since I have done this)

$r=\frac{24}{48} =\frac{1}{2}$

So we found the relationship! Now we find the entire equation.

So we know the first term, 96, so let's use it!

$a_{n} =96*(\frac{1}{2})^{n-1}$

So there is the equation!

Now to find the 10th term.

$a_{n} =96*(\frac{1}{2})^{n-1}\\a_{10} =96*(\frac{1}{2})^{9}\\a_{10} =96*\frac{1}{2^{9} } \\a_{10}=0.1875$

There you have it!

Hope this Helps!

P.S. Stay Safe!

Answer:

Step-by-step explanation:

Since the pennies need to be kept under the pillow in order to be doubled, we're really looking for the day the girl will wake up with 5 billion pennies under her pillow.

The general formula of that geometric sequence will be: t = 1 + 2^(n-1)

We need to find the value of n when t will be over 5,000,000,000.

So, the equation becomes:

5,000,000,001 = 1 + 2^(n-1)

2^(n-1) = 5,000,000,000

log(2^(n-1)) = log(5,000,000,000)

(n-1) * log(2) = log(5,000,000,000)

n-1 = log(5,000,000,000) / log(2)

n-1 = 22.25

n = 33.25

Since it has to be complete days, and we have to reach over 5 billion, then we round it up to 34.
