For a finite sequence of nonzero numbers, the number of variations in sign is defined as the number of pairs of consecutive term

elena55 [62]

Answer:

The no. of variations in sign is 3

Step-by-step explanation:

Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.

Therefore, the determination of the number of changes in sign in the given sequence is must.

Therefore, we take the product of the pair of consecutive terms as:

$1\times (-3)$ = - 3, variation in sign

$(-3)\times 2$ = - 6, variation in sign

$2\times 5$ = 10, no sign variation

$5\times (- 4)$ = - 20, variation in sign

$- 4\times (-6)$ = 24, no sign variation

I need the answers for this one as well!

Julli [10]

For the sake of showing work I will replace the empty space with an x like so...

$\frac{9}{10} =\frac{90}{x}$

To find out what x is you must cross multiply (aka butterfly)

***Image of this step is attached below

9*x = 10*90

9x = 900

Next divide 9 to both sides to finish isolating x. Since 9 is being multiplied by x, division (the opposite of multiplication) will cancel 9 out (in this case it will make 9 one) from the left side and bring it over to the right side.

9x ÷ 9 = 900 ÷ 9

1x = 100

x = 100

To make these fractions equivalent the empty spot must be 100

$\frac{9}{10} = \frac{90}{100}$

Hope this helped!
