On the day that a certain celebrity proposes marriage, 252525 people know about it. Each day afterward, the number of people who
know triples.
Which graph shows the number yyy of people who know about the proposal xxx days afterwards?
Which graph shows the number yyy of people who know about the proposal xxx days afterwards?

Answer:
A
Step-by-step explanation:
The graphs are attached.
First of all, the day proposal goes out, 25 people know, so the initial condition is y = 25 at x = 0.
Hence, graph would start at y = 25.
Looking at the graphs, we can eliminate B and D immediately because they start at 50.
Now, it says every day, this number (y) triples, so 1 day after, it would be:
25 * 3 = 75
So, the graph would show x = 1 and y = 75
We can eliminate "C" as it doesn't show 75 at x = 1.
And we look at A and it is correct.
So,
A is the graph of the situation represented.

Answer:
Step-by-step explanation:
We want to find the distance between two points, so the following formula is used.
Where (x₁, y₁) and (x₂, y₂) are the points we are finding the distance between.
We are given the points (-2, -1) and (3,2). If we match the corresponding value and variable we see that:
- x₁= -2
- y₁= -1
- x₂= 3
- y₂= 2
Substitute the values into the formula.
Solve the parentheses.
- -2 -3 = -5
- 2--1 = 2+ 1 = 3
Solve the exponents.
- (-5)²= -5*-5= 25
- (3)²= 3*3=9
Add.
This radical cannot be simplified, so the distance between the two points is <u>√34</u> and <u>choice 3 </u> is correct.

Step-by-step explanation:
Given sequence is:
6, 18, 54, 162,....
Here
(a) Is this an arithmetic or geometric sequence?
We can see that the difference between the terms is not same so it cannot be an arithmetic sequence.
We have to check for common ratio (ratio between consecutive terms of a sequence) denoted by r
As the common ratio is same, the given sequence is a geometric sequence.
(b) How can you find the next number in the sequence?
Recursive formulas are used to find the next number in sequence using previous term
Recursive formula for a geometric sequence is given by:
In case of given sequence,
So to find the 5th term
(c) Give the rule you would use to find the 20th week.
In order to find the pushups for 20th week, explicit formul for sequence will be used.
The general form of explicit formula is given by:
Putting the values of a_1 and r
