Tilly begins a running program to train for a marathon. She starts by running 1 mile the first week and tripling the number of m

Nuetrik [128]

Answer:

The sequence is a function as for any value of n we can not get more than one different $A_n$ value.

Step-by-step explanation:

Tilly starts by running 1 mile in the first week and tripling the number of miles each week.

Now, the number of miles Tilly will run can be modeled by the sequence $A_n = 1 \times 3^{(n - 1)}$ , where n is the number of weeks since she began her program.

Therefore, in the second week she runs 3 miles, in the third week she runs 9 miles and so on.

Therefore, the sequence is a function as for any value of n we can not get more than one different $A_n$ value. (Answer)

The sum of 555 consecutive integers is 270270270. What is the second number in this sequence?

Simora [160]

The second number in the sequence will be 53.

Explanation

The difference between any two consecutive integers is always 1.

Suppose, the five consecutive integers are: $n$ , $n+1$ , $n+2$ , $n+3$ and $n+4$

Given that, their sum is 270. So, the equation will be......

$n+(n+1)+(n+2)+(n+3)+(n+4)=270\\\\ 5n+10=270\\\\5n=270-10=260\\ \\ n=\frac{260}{5}=52$

Thus, the second number in the sequence will be: $n+1= 52+1=53$

Select all of the pieces of information that would tell you x and y have a proportional relationship. Let y represent the distan

natima [27]

Complete Question:

Select all of the pieces of information that would tell you x and y have a proportional relationship.

Let y represent the distance between a rock and a turtle's current position in meters and x represent the number of minutes the turtle has been moving. y=3x

1. After 4 minutes, the turtle has walked 12 feet away from the rock.

2. The turtle walks for a bit, then stops for a minute before walking again.

3. The turtle walks away from the rock at a constant rate.

Answer:

1. After 4 minutes, the turtle has walked 12 feet away from the rock.

3. The turtle walks away from the rock at a constant rate.

Step-by-step explanation:

Given

$y = 3x$

Required

Determine which of the options answers the question

Recall that:

$y = distance$

$x = time$

Analyzing the options 1 after the other:

Option 1:

In this option, we have that:

$y = 12$

$x = 4$

Substitute these values of x and y in the given equation

$y = 3x$

$12 = 3 * 4$

$12 = 12$

Because both sides of the equation are equal, this option shows a proportional relationship

Option 2:

The given equation cannot be used to ascertain the information given in this option.

Because for a every time (in minutes) traveled by the turtle, there's a corresponding distance moved.

Option 3:

Recall that

$y = 3x$

Assume $x = 5$

y would be

$y = 3 * 5$

$y = 15$

Assume $x = 6$

y would be

$y = 3 * 6$

$y = 18$

For every values of x and corresponding y value, there exist a constant relationship because:

$\frac{y}{x} = 3$

This implies that the rate at which the turtle moved is 3ft/s and this rate is constant.
