Someone tell me if these sequences are arithmetic, geometric, or neither

1 answer:

5 0

1. A constant number isn't being added so it's not arithmetic. To get from 2 to 7, you'd be multiplying by 7/2 or 3.5. To get from 7 to 27, you'd be multiplying by 27/7 or 3.85. This means that there isn't a constant rate so it's not geometric either. This one is neither.

2. 16 divided by 4 is 4, 4 divided by 4 is 4, 1 divided by 4 is 1/4, so this one is geometric with a constant of 4.

3. To get from 71 to 62, subtract 9. To get from 62 to 53, subtract 9. This means that it's arithmetic with a constant of 9.

A fire department's ladder is 110 feet long. A firefighter is trying to reach the top of a 100 foot building by leaning the ladd

Alekssandra [29.7K]

Answer:

sin-¹(10/11)

Step-by-step explanation:

The height of the building is 100 ft and the ladder is 110ft long .We can imagine this situation as a right angled ∆. For figure refer to the attachment .

We can use ratio sine here. Let the angle of elevation be theta.

In ∆ ABC :-

=> sinθ = p/h

=> sinθ = 100ft / 110 ft

=> sinθ = 10/11

=> θ = sin -¹ ( 10/11) .

<h3>Hence the angle of elevation is sin -¹ ( 10/11). </h3>

emmasim [6.3K]

Answer:

Step-by-step explanation:

At the lying lemon used car company each salesperson makes $5.75 per hour and receives 6 1/2% commission on sales. Converting

6 1/2% to decimal, it becomes 6.5%

If a Salesperson worked for 8 hours, the amount that he would earn would be

8 × 5.75 = $46

If the salesperson sold a car for $9290, his commission would be

6.5/100 × 9290 = 0.065 × 9290 = $603.85

Total amount that the sales person would earn is

46+ 603.85 = $649.85
