Answer:

The recursive formula to generate the sequence 9.6,-4.8,2.4,-1.2,0.6....

a_n=-\frac{a_n-1}{2}

Step-by-step explanation:

Given

f(1)=9.6

The given sequence

9.6,-4.8,2.4,-1.2,0.6....

a_1=9.6

a_2=4.8

a_3=2.4

\frac{a_2}{a_1} =\frac{-1}{2}

a_2=-\frac{a-1}{2}

similarly , we get

\frac{a_3}{a_2} =\frac{2.4}{-4.8}

By simplification we get

a_3=-\frac{a_2}{2}

..................................................

......................................................

a_n=-\frac{a_n-1}{2}

Hence, the recursive formula for the given sequence

a_n=-\frac{a_n-1}{2}.

N-1(-1/2) is the formula because the sequence is taking half of the previous number and changing its sign

Ferromagnetic (for the purposes of this page, at least) means that they will align themselves with a magnetic field. That being the case, iron filings are an excellent way to display the magnetic field of one or multiple bar magnets.

X+9=2x-3<br> FIND THE X!!!!!!
Ierofanga [76]

Answer:

x = 12

Step-by-step explanation:

<u>To find "x"</u>, we need to <u>isolate it</u>. This means move "x" to the left side, and everything else to the right side.

When moving a number, do its <u>reverse operation</u> to the entire equation.

x + 9 = 2x - 3

x - 2x + 9 = 2x - 2x - 3         Subtract 2x from both sides

-x + 9 = -3                              

-x + 9 - 9 = -3 - 9           Subtract 9 from both sides

-x = -12

-x/-1 = -12/-1          Divide both sides by -1 to get rid of the negatives

x = 12                     Final answer

Check your answer. Split the equation for the left and right sides. Substitute "x" for the answer "12".

LS:   (left side)

x + 9

= 12 + 9              Add

= 21

RS:   (right side)

2x - 3

= 2(12) - 3            Multiply before subtracting

= 24 - 3               Subtract

= 21

Both sides equal to 21 when "x" is 12.

LS = RS          left side equals right side

Therefore the answer is correct.

Simplify without using the absolute value sign<br><br> | x- ( - 18) | if x &gt; - 18
slega [8]
The expression would be > 0.

Subtracting a negative is the same as adding a positive; therefore -18--18 = -18+18 = 0.  Since we know that x>-18, 0 is below anything we could get from this.
