A car travels 258 miles in 312 minutes at a constant speed. Which equation represents the distance, d, that the car travels in m

pashok25 [27]

Answer:

0.83 miles per minute

Step-by-step explanation:

The speed of the car can be found by dividing the distance by the time. THe distance is 258 miles and the time is 312 minutes.

$s=\frac{d}{t} \\s=\frac{258}{312} \\s=0.83$

Darnell starts the month $952.43 in his checking account. Darnell buys an iPhone 7 for $217.49 with tax included, and two kindle

ki77a [65]

Answer:

Therefore his new balance=$712.95

Therefore his new balance is =$ 930.44

Step-by-step explanation:

Darnell starts the month $ 952.43 in his checking account.

He buys an iPhone 7 for $ 217.49 with tax included and two kindle books that each $7.99.

The price of two books is =$(7.99× 2)= $ 15.98

Total amount that he paid for iPhone 7 and two books is =$(217.49+15.98)

=$233.47

Therefore his new balance = $(952.43- 233.47)

=$712.95

The new iPhone 7 is not as awesome as promised , and Darnell returns it.

He will get the price of iPhone refund.

Therefore his new balance is $(712.95+217.49)

=$ 930.44

- Write a recursive formula to represent the sequence below. (3,7, 11, 15, 19,23,27,31,35, ...)

NemiM [27]

The recursive formula to find nth term of sequence is:

$a_n = 4n - 1 \text{ where } n \geq 1$ and n = 1, 2, 3, ....

Solution:

Given a sequence is:

3, 7, 11, 15, 19, 23, 27, 31, 35

Let us find the difference between terms

7 - 3 = 4

11 - 7 = 4

15 - 11 = 4

19 - 15 = 4

23 - 19 = 4

27 - 23 = 4

31 - 27 = 4

35 - 31 = 4

Thus the difference between terms is constant

Thus the given sequence is arithmetic sequence

An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant

The nth term of arithmetic sequence is given by:

$a_n =a_1+(n-1)d$

$a_n$ = the nᵗʰ term in the sequence

$a_1$ = the first term in the sequence

d = the common difference between terms

Here in the given sequence

d = 4

$a_1=3$

Substitute in above formula,

$a_n = 3 + (n-1)(4)\\\\a_n = 3 + 4n - 4\\\\a_n = 4n - 1$

Thus the recursive formula to find nth term of sequence is:

$a_n = 4n - 1 \text{ where } n \geq 1$ and n = 1, 2, 3, ......
