T3=-6.5 and t5=-3.9 determine d

nekit [7.7K]

$t_3=-6.5;\ t_5=-3.9\\\\t_5-t_3=2d\\\\2d=-3.9-(-6.5)\\\\2d=-3.9+6.5\\\\2d=2.6\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{d=1.3}$

How do I solve #14????

Tcecarenko [31]

All the measures in a triangle are equal to 180 degrees.

Let the unknown angle= x.

40+89+x= 180

Combine like terms.

129+x= 180

Subtract 129 from both sides.

x= 51

The angle is equal to 51.

I hope this helps!

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
