PI x r^2 is the equation for the area of a circle. Clearly, we have 3 quarters of a circle here, so we can divide our answer by 4 and then multiply it by 3.

PI x 10^3 = 314.159...

Divide by 4 = 78.540...

Multiply by 3 = 235.619...

Therefore the answer is the third one.

Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n > 1?

Degger [83]

The recursive formula $a_n = a_{n-1}-6$ can be used to generate the shown sequence

Step-by-step explanation:

Recursive formula is the formula that is used to generate the next term of a sequence using previous term.

The general form of arithmetic sequence's recursive formula is:

$a_n = a_{n-1}+d$

Given

5,-1,-7,-13,-19

Here

$a_1 = 5\\a_2 = -1\\a_3 = -7$

First of all we have to find the common difference of the sequence.

So,

$d = a_2 -a_1 = -1-5 = -6\\d = a_3-a_2 = -7+1 = -6$

Putting the value of d in the general recursive formula

$a_n = a_{n-1}-6$

Hence,

The recursive formula $a_n = a_{n-1}-6$ can be used to generate the shown sequence

You can drive 60 miles on 1/2 of a tank of gas in 1 hour? How far can you drive on one tank of gas

REY [17]

Answer:

120 miles in 2 hours

Step-by-step explanation:

120 because half of a tank is 60 miles so a whole tank means double half, which gives 120 and you also double the hour to 2 hours.
