The formula for any geometric sequence is an = a1 · rn - 1, where an represents the value of the nth term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the sequence -3, -6, -12, -24, ...?

an = -3 · 2 n - 1
an = -3 · (-2) n - 1
an = 2 · (-3) n - 1
an = -2 · (-3) n - 1

Answers

Answer: an = -3 · 2^n - 1

Step-by-step explanation:

In a geometric series, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

an = a1 × r^(n - 1)

Where

a1 represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

Looking at the given sequence,

a = - 3

r = - 6/ - 3 = 2

Therefore, the formula for the sequence is

an = - 3 × 2^(n - 1)

Write an exponential growth function, and then describe a real-world situation that the
function could represent. Do the same for an exponential decay function. Share your
functions and the situations they represent.

Answers

Answer:

Step-by-step explanation:

Exponential growth function can be represented as follows

y =

Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or

dy / dt =by , or rate of increase depends upon y itself

dy / y = bdt

integrating on both sides

lny = bt

y =

It represents very fast increase in y .

The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.

For exponential decay function

y =

The decay of   a radioactive material is an example of exponential decay function.

Pablo purchased adult and youth tickets for the football game. He bought x adult tickets for $74 each and y youth tickets for $35. Write an expression that can be used to show the total cost, C, of all tickets. (4 points) a C = (74 + 35)x b C = (74 + 35)(x + y) c C = 74y + 35x d C = 74x + 35y

Answers

Answer:

c=74x+35y     (answer c)

Explanation:

The adult tickets are x and the youth tickets are y. They are not influenced by but add up to the total coast.

A does not work because it is 35+74 multiplied by the amount of tickets needed for adults. B does not work because it mulitplies the cost of tickets by the amount of tickets needed. Therefore C is right.

The answer is C= 74x +35y

You should have the appropriate variable with the appropriate price, so the x for adult tickets goes with the prices for adult tickets and y for number of youth tickets to go with youth prices.

Since these numbers are separate and different, you don't want to combine them like A and B do.

−8⋅f(1)−4⋅g(4)= Help me please!!

Answers

Answer: -8

Step-by-step explanation:

−8 * f(1) −4 * g(4)

= -8 * (-2) -4 * 6

= 16 - 24

= -8

The calculated value of the given expression is "-8f-16g" following are the calculated steps for the  given expression:

Expression calculation:

= −8 × f(1) −4 × g(4)

= −8 × 1 × f −4 × 4 ×g

= −8f  −16g

Explanation of the evaluation of the expression:

In the above-given expression the value of f(1) will be "1 × f", and similarly the g(4) the value will be equal to "4 × g" that's why the calculated value of the given expression will be equal to  "−8f  −16g".

So, the final evaluated value of the given expression will be "−8f  −16g".
