Determine whether each sequence is arithmetic or geometric. Sequence 1: –10, 20, –40, 80, ... Sequence 2: 15, –5, –25, –45, ...A. Sequence 1 is arithmetic and Sequence 2 is geometric.

B. Both sequences are geometric.

C. Sequence 2 is arithmetic and Sequence 1 is geometric.

D. Both sequences are arithmetic.

sequence 2 may be arithmetic because -20 but I can't find out what sequence 1 is

Answer:

Assuming that both vehicles have the same mass: It´s 9 times

Step-by-step explanation:

You can use the formula for kinetic energy which is:

We can calculate two different values for each speed. We assume that the mass is "m"

As you can see the K2 is 9 times bigger than K1

If Charlie has $20 and needs to rent shoes then he must bowl 25 games.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Let represent number of games that Charlie can bowl "x".

The cost of renting shoes is given as $1.25.

The cost of each game is given as $0.75.

So the total cost of bowling x games, including the cost of shoe rental, is:

Total cost = Shoe rental + (Cost per game x Number of games)

Total cost = $1.25 + ($0.75 x x)

Total cost = $1.25 + $0.75x

We know that Charlie has $20 to spend.

So we can set up an equation that equates the total cost of bowling to $20:

$1.25 + $0.75x = $20

Solving for x, we can subtract $1.25 from both sides and then divide by $0.75:

$0.75x = $18.75

x = $18.75 / $0.75

x = 25

Hence, if Charlie has $20 and needs to rent shoes then he must bowl 25 games.

undefined

Answer:

C) Undefined

Step-by-step explanation:

When the slope on a graph is straight there is no slope so therefore it is undefined.
