A type of cell reproduces by splitting itself in half. One cell becomes 2 cells, 2 cells become 4 cells, and 4 cells become 8 cells. What type of sequence does the number of cells represent, and why? It represents an arithmetic sequence because it has a common difference of 2. It represents an arithmetic sequence because it has a common difference of 1/2. It represents a geometric sequence because it has a common ratio of 1/2. It represents a geometric sequence because it has a common ratio of 2.

Answers

Answer 1

Answer:

It represents a geometric sequence because it has a common ratio of 2.

In fact, a sequence is said to be geometric if any two adjacent elements are in the same ratio. In other words, if you choose any index $n \in \mathbb{N}$ and consider the two consecutive terms $a_n$ and $a_(n+1)$ , you have

$(a_(n+1))/(a_n) = r$

no matter which index you chose. In your case, the next term in the sequence is always the double of the previous one, so the ratio between two consecutive terms is always 2, and the series is geometric with common ratio 2

Answer 2

Answer:

Answer:

on edge 2021, your answer would be D.) It represents a geometric sequence because it has a common ratio of two.

What is the domain of the function y=ln(12-4x/5)

Answers

Answer:

The domain of the function is $x<3$

Step-by-step explanation:

Given : Function $y=\ln ((12-4x)/(5))$

To find : What is the domain of the function ?

Solution :

Domain is defined as the set of possible values which define the function.

We know that, log negative is not defined.

So, we will get the inequality in the function.

$\ln ((12-4x)/(5))>0$

$(12-4x)/(5)>0$

$12-4x>0$

$-4x>-12$

$x<3$

Therefore, The domain of the function is $x<3$

$\ln x$ has a domain of $x>0$ , so $\ln\left(12-\frac{4x}5\right)$ has a domain of

$12-\frac{4x}5>0\implies12>\frac{4x}5\implies x<15$

What is the result of the following division?

Answers

For this case we must indicate the result of the following expression:

$\frac {2x ^ 3-3x + 5} {x + 3}$

We must build a quotient that, when multiplied by the divisor, eliminates the terms of the dividend until it reaches the remainder.

It must be fulfilled that:

Dividend = Quotient * Divider + Remainder

Ellie and heather drew floor models of their living rooms. Ellie's model represented 20 feet by 15 feet. Heathers model represented 18 feet by 18 feet. Whose floor model represents the greater area? How much greater?

Answers

Answer:

Heather's model has greater area by 24 sq.ft.

Step-by-step explanation:

Given : Ellie's model represented 20 feet by 15 feet.

Heather's model represented 18 feet by 18 feet.

To Find: Whose floor model represents the greater area? How much greater?

Solution:

Length of Ellie's model = 20 feet

Width of Ellie's model = 15 feet

Area = $Length * Breadth$

= $20*15$

= $300ft^2$

Length of Heather's model = 18 feet

Width of Heather's model = 18 feet

Area = $Length * Breadth$

= $18*18$

= $324ft^2$

Thus Heather's model has greater area by (324-300)= 24 sq.ft.

Heather's model is 324 square feet and Ellie's is 300 square feet. Therefore Heathers models is 24 square feet more than Ellie's model.

Jorge was tracking the decreasing temperature in the morning. At 7 a.m., it was 65 degrees Fahrenheit. At 9 a.m., it was 55 degrees Fahrenheit. If Jorge made the function f(x) = −5x + 100, what would the −5 represent?

Answers

so at 7 am it was 65 and 9 am it was 55 which means each hour it was dropping 5 degrees so probably -5 degrees each hour
