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

marta [7]

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.

8-6x>-18 solve for x

EleoNora [17]

Answer:

x=5

Step-by-step explanation:

Well all i did was guess a random number from 1-10 so I could see what numbers make the equation bigger than -18 and the fist thing I guessed was 5 so this is what I did

8-6*5=-22

And them I said let me see if any multiples equal -18 so I went to for and did this

8-6*4=-16

That's when I guessed the answer if i looked at the sign correctly!

BRAINLIEST!!<br> 1. Identify the domain and range of each function.

denpristay [2]

Answer:

The fourth listed answer:

Domain: All Real numbers

Range : { f{x) | f(x) $\leq$ 0, f(x) = 1 }

Step-by-step explanation:

The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.

The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value "x" of the domain. The line with positive slope extends to all f(x) values that are $\leq$ 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.

I need to know these answers fast please please help!!!!

meriva

Answer:

Step-by-step explanation:

y intercept please scroll down--i need to see the rest of the graph-- y intercept is where the graph intersects with the y axis

x intercepts are x=2 and x=6

greatest value of y is y=2 and it occurs when x=4

for x between... what are the options?

if the options are greater than, equal to, or less than, the answer is greater than

To draw a gragh for y = 2x +5, a person can draw a point at x of 0 and y of _, a second point by going over 1 and ip _, and then

Verdich [7]

Answer: A person can draw a point of x of 0 and y of 5, a second point by going over 1 and up 2, and then draw a line through the points.

Step-by-step explanation:

if x is equal to 0 then y will equal to 5 which in this case will represent the y intercept. And after plotting the point (0,5) you can use the slope and move over or left by 1 and move up by 2 to find the next point.
