What is the recursive formula for this geometric sequence? -3,-21

maksim [4K]3 years ago

A recursive formula is stating what the first value is, and how to get to the next number given the previous number.

Since the first number is 3, our first part is a₁=3 (if a is the function). Next, to get to -21, we multiply 3 by -21/-3=7. Therefore, aₓ(if x is the nth term of the function)=7*a₍ₓ₋₁₎ due to that we multiply 7 by the previous number

OLEGan [10]

Answer:

Step-by-step explanation:

Answer:

Imperfect substitutes

explanation:

The choices above are not perfect substitutes, meaning they can not be perfectly or directly replace the other. Imperfect substitutes are close substitutes but not perfect substitutes. Unlike perfect substitutes, imperfect substitutes satisfies same utility but has different characteristics and therefore not entirely substitutable. For example, while one may want to have the 40 marks too, he'd rather have 60 marks even if the criteria for a 60 mark score was increasingly hard.

Solve in simultaneou linear equation.
dangina [55]

Answer:

The bag costs 1500, while the umbrella cost 500

Step-by-step explanation:

Let the cost of the bag be b and the cost of the umbrella be u

Total cost is;

b + u = 2,000 •••••(i)

From the second part of the question;

b = 5u-1000 ••••••(ii)

Substitute ii into i

5u-1000 + u = 2000

6u = 2000 + 1000

6u = 3000

u = 3000/6

u = 500

To get b, substitute the value of u into equation ii

b = 5(500)-1000

b = 2500-1000

b = 1500
