Answer:

$a_{15} = 2147483648$

Step-by-step explanation:

first, find the common ratio (r) by dividing the second term by the first term:

r = 32 / 8 = 4

next, write a formula for the geometric sequence:

$a_{n} = a_{1} * (r)^{n-1} \\a_{15} = 8 * (4)^{14} \\a_{15} = 2147483648$

Blababa [14]

Answer:

$X = $12y

Step-by-step explanation:

In this question, we are asked to give an expression to represent the amount of money charged to a man who stayed in a motel for a particular number of days.

Firstly, we need to know the amount of money charged per day. This is visible from

the question and it is equal to $y.

Secondly, the number of days/night stayed is 12 days. This means that the amount of money he was charged is 12 * y = $12y

Since the amount of money charged is equal to $x, the amount to pay can be expressed in terms of y and x to be

$X = $12y

If f(x) = -x + 8 and g(x) = x^4, what is (gºf)(2)?

kotykmax [81]

Answer:

$\large\boxed{(g\circ f)(2)=1296}$

Step-by-step explanation:

$(g\circ f)(x)=g\bigg(f(x)\bigg)\\\\f(x)=-x+8,\ g(x)=x^4\\\\(g\circ f)(x)=\g\bigg(f(x)\bigg)=(-x+8)^4\\\\(g\circ f)(2)\to\text{put x = 2 to the equation}\ (g\circ f)(x):\\\\(g\circ f)(2)=(-2+8)^4=(6)^4=1296$

Orlov [11]

Answer:

625

Step-by-step explanation:

Convert 15300 to a percent,

We can convert it to it's lowest fraction,

120, and to find the percent just multiply it by 5 on top and bottom,

120 ×5×5

which equals, 5100

Then take the percent as a decimal, 0.5 and multiply it by 12500,

12500×0.5 which would give you: 625

It's easy it's called Two-way tables please help

Vesnalui [34]

Answer: The filled out table is shown below in the attached image

===========================================================

Explanation:

The letters A through J are one way to fill out the table. Though there are other possible orders.

Start at letter A, which is from the fact we have 40 people total

Then move to letter B. This is the total number who like pasta (26)

We have C = A-B = 40-26 = 14 people who don't like pasta

--------------

Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.

F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.

Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.

----------------

So we have these values

A = 40
B = 26
C = 14
D = 21
E = 19
F = 4
G = 17
H = 9
J = 10
