The first sequence rule is subtract 8 starting from 72. The second sequence rule is subtract 6 starting from 58. What is the fir
Darya [45]

Answer:

A) 16

Step-by-step explanation:

1st sequence: 72-8x

2nd sequence: 58-6x

Set both sequences equal to each other and solve for x:

72-8x=58-6x

14-8x=-6x

14=2x

7=x

x=7

Plug x=7 back into the equation:

72-8(7)=58-6(7)

72-56=58-42

16=16

So the first number that appears in both sequences is 16.

A. Use what you've learned in this unit to model the population of Western
Leona [35]

An exponential function can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

However, the following is a general guide to solve the question.

An exponential function is represented as:

y=a(1 \pm r)^x

Where:

  • (a) represent the initial value i.e. the initial population of the Western Lowland Gorillas
  • (r) represents the rate at which the population increases or decreases.
  • (x) represents the number of years since 2022
  • (y) represents the population in x years

Given that the population of the Western Lowland Gorillas decreases, then the rate of the function would be 1 -r (i.e. an exponential decay)

Take for instance:

y = 20000 * 0.98^x

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

If x=3 what is 3x -5(9x3) divided by 2 and does any one wanna talk and at school?
mart [117]
<h3>Given :- </h3>

\quad \qquad \bullet \quad \sf x = 3

<h3>To Find :- </h3>

\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}

<h3>Solution :- </h3>

Let's Start :-

\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}

Putting the respective value of x we have ;

{ : \implies \quad \sf \dfrac{3\cdot 3- 5 (27 )}{2}}

{ : \implies \quad \sf \dfrac{9- 135}{2}}

{ : \implies \quad \sf - \dfrac{126}{2}}

{ : \implies \quad \bf - 61}

\quad \qquad { \bigstar { \underline { \boxed { \pmb { \bf { \red { \underbrace { \therefore \dfrac{3x - 5 ( 9 \times 3 )}{2} = - 61}}}}}}}}{\bigstar}
