Step-by-step explanation:

A=9b/2 + 315/2

2A = 9b +315

-9b = 315-2A

b=-35 + 2A/9

b=2A/9-35

Answer:

\boxed{\mathrm{view \: explanation}}

Step-by-step explanation:

Two numbers that only have 1 as a common factor are called co-prime numbers.

<u>Example:</u>

Factors of 3 ⇒ 1, 3

Factors of 4 ⇒ 1, 2, 4

These numbers only have 1 as a common factor. So 3 and 4 are co-prime numbers.

Write a recursive formula and an explicit formula for the following arithmetic sequence: -1,6,13,20,27
Luden [163]

Answer:

Recursive formula is: a_1=-1 ; \ \ a_n=a_{n-1}+7

Explicit formula is: a_n=7n-8

Step-by-step explanation:

We need to find recursive formula and explicit formula for arithmetic sequence -1,6,13,20,27

In the given sequence First term a₁= -1

Common difference d = 7

Finding Recursive Formula

The recursive formula is of type:a_1= First \ term and a_n=a_{n-1}+d

Since the First term a₁ is -1 and common difference d is 7 so, the recursive formula  for given arithmetic sequence will be:

a_1=-1 ; \ \ a_n=a_{n-1}+7

Finding Explicit Formula

The explicit formula is of type: a_n=a_1+(n-1)d

We have

First term a₁= -1

Common difference d = 7

So, explicit formula will be:

a_n=-1+(n-1)7\\a_n=-1+7n-7\\a_n=7n-8

So, explicit formula is: a_n=7n-8

Answer:

55 mph

Step-by-step explanation:

First hour: 40 mph

Second, Third, Fourth hours:

180 miles / 3 hours = 60 mph

Average: 40 (hour 1) + 60 (hour 2) + 60 (hour 3) + 60 (hour 4) = 220 / 4 hours = 55 mph average
