Answer:

2nd one

as the y is both 4, the points are on the same plane. As such, we care about the distance of x which is between 3 and 7

Find the slope of the point, and reduce the lowest terms (7,3)(9,3)

Umnica [9.8K]

A point doesn't have a slope. A line has. You need to find the slope of the line that these 2 points are on. The slope is

(the difference of the 'y' values) divided by (the difference of the 'x' values)

That appears to be zero. It's a horizontal line.

A leprechaun places a magic penny under a girl's pillow. The next night there are 2 magic pennies under her pillow. The followi

Mars2501 [29]

Answer:

36 days

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 21 billions 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 21,000,000,000.

So, the equation becomes:

21,000,000,001 = 1 + 2^(n-1)

2^(n-1) = 21,000,000,000

log(2^(n-1)) = log(21,000,000,000)

(n-1) * log(2) = log(21,000,000,000)

n-1 = log(21,000,000,000) / log(2)

n-1 = 34.29

n = 35.29

Since it has to be complete days, and we have to reach over 21 billions, then we round it up to 36.

1. A bag has tiles with two-digit numbers (10-99) on them. A random tile is 4 points

stiks02 [169]

Answer:

Step-by-step explanation:

The probabilty is defined as the ratio between the total events and the total outcomes possible.

In this case, we have 90 total outcomes, which are all two-digit numbers. The event is only one, the number 32. Using the definition, we have

$P=\frac{1}{90}$

Therefore, the right answer is B.
