The first sequence rule is multiply by 2 starting from 7. The second sequence rule is add 2 starting from 8. What is the first number that appears in both sequences?
Question 3 options:

Answers

The first and the second sequence are arithmetic and geometric sequence, respectively

The first number in both sequences is 14

How to determine the first number?

From the question, we have the following rules

Rule 1

Start = 7

Multiply by 2

Rule 2

Start = 8

Add = 2

So, the numbers in the sequence are:

Rule 1: 7, 14, 28, 56......

Rule 2: 8, 10, 12, 14, .....

By comparing the numbers in the sequence, we can see that the first number in both sequences is 14

Do the functions have the same concavity? f(x)=-x^2+40x+120f(x)=−x 2 +40x+120

Answers

Answer:

1. f(x)=-x^2+40x+120. Answer: it would be the same answer

2. f(x)=−x 2 +40x+120. Answer: look at the both picture

Step-by-step explanation: Hope this help :D

Both functions have the same concavity—they are both concave downward.

How to explain the function

Let's start with the first function, f(x) = -x² + 40x + 120.

First Derivative:

f'(x) = -2x + 40

Second Derivative:

f''(x) = -2

Since the second derivative is a constant (-2), it is negative for all values of x. Therefore, the first function has a concave downward shape.

Now let's move on to the second function, f(x) = -x² + 40x + 120.

First Derivative:

f'(x) = -2x + 40

Second Derivative:

f''(x) = -2

Similar to the first function, the second function also has a constant second derivative (-2) that is negative for all values of x. Therefore, the second function also has a concave downward shape.

In conclusion, both functions have the same concavity—they are both concave downward.

4/5y - 8 = 2/5y + 16

Answers

Answer:

y=60

Step-by-step explanation:

trust

y = 60

Step-by-step explanation:

Step 1: Group all the x terms on the left side of the equation

Subtract y from both sides:

4/5y - 8 = 2/5y + 16

4/5y - 8 - 2/5y = 2/5y + 16 - 2/5y

2/5y - 8 = 2/5y + 16 - 2/5y

2/5y - 8 = 16

Step 2: Group all constants on the right side of the equation

Add 8 to both sides of the equation:

2/5y - 8 = 16

2/5y - 8 + 8 = 16 + 8

2/5y = 16 + 8

2/5y = 24

Step 3: Isolate the x

Multiply both sides by inverse fraction 52

2/5y = 24 5/2

2/5y 5/2 = 24

y = 24 5/2

y = 60

What is dot plot?

A dot plot visually groups the number of data points in a data set based on the value of each point.

Given that, the following dot plot shows how many times each teammate was late to practice last week.

We need to find mean,

Total elements = 2 + 4 + 4 + 4 = 14

Data points = 4

Mean = 14 / 4 = 3.5

Answer:

663

Step-by-step explanation:

the total number of students can be determined using this equation :

(total ratio of Chinese and Indian students / total ratio of students) x n = 468

total ratio of Chinese and Indian students = 4 + 8 = 12

total ratio of students 4 + 8 + 5 = 17

N = TOTAL NUMBER OF STUDENTS

12/17) x n = 468

multiply both sides of the equation by 17/12

n = 663

While many cases involve runaways or people who return home, Alaska also has the highest percentage of missing people who are never found [source: Tizon].In 2007, Alaska state troopers added 2,833 missing person notices to their Missing Persons Clearinghouse that maintains all related information [source: Alaska Governors Office]. In a state with just over 670,000 residents, that figure averages out to about four in every 1,000 people.Along with missing persons reports, state troopers oversee search and rescue operations. In 2007, they performed 42 missions related to overdue hikers, 85 related to overdue boaters and 100 related to overdue snow machine operators who were temporarily missing [source: Alaska Governors Office].
