Answer:

10th term = -88.

Step-by-step explanation:

This is an arithmetic sequence with first term = 20 and common difference -12.

nth term = a1 + (n - 1)d

10th term = 20 + (10-1)*-12

= 20 - 108

= -88.

Find the 10th term in the following arithmetic sequence if the constant being added is -12

Step-by-step explanation:

20 - 12 = 8

8 - 12 = -4

-4 - 12 = -16

So the sequence will be

20; 8; -4; -16

an = 20 - 12(n - 1)

a10 = 20 - 12(10 - 1) = -88

on Tuesday pierce ran 3/4 mile and walked 3/4 on Wednesday he ran 2/4 mile and walk 1 1/4 miles hiw much farther did pierce run

Korvikt [17]

Answer:

On Tuesday

3/4 + 3/4 = 3/2 = 1 1/2 = 1.5

On Wednesday

2/4 + 1 1/4 = 7/4 = 1 3/4 = 1.75

Then we subtract

1.75 - 1.5 = 0.25

Consider the sequence 3, -9, 27, -81, .. Find the 14th term of the sequence.

bagirrra123 [75]

Answer:

let 'a' be the first term, 'd' be the common difference between all the terms of the sequence

Step-by-step explanation:

therefore, a = 3,

and, d = -9 -3

= -12

hence the 14th term would be,

=> a + 13d

=> 3 + 13( -12 )

=> 3 - 156

=> - 153

Chose all the values of x that are not in the domain of this rational function. Picture attached, 15 points and I'll give Brainl

pogonyaev

Answer:

All of them.

Step-by-step explanation:

For rational functions, the domain is all real numbers <em>except</em> for the zeros of the denominator.

Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:

$x(x-1)(x^2-4)=0$

Zero Product Property:

$x\neq 0\text{ or }x-1\neq 0\text{ or }x^2-4\neq 0$

Solve for the x in each of the three equations. The first one is already solved. Thus:

$x-1\neq 0 \text{ or }x^2-4\neq 0\\x\neq 1\text{ or }x^2\neq 4\\x\neq 1 \text{ or }x\neq\pm 2$

Thus, the values that <em>cannot</em> be in the domain of the rational function is:

$x=-2,0,1,2$

Click all the options.

If m∠D + m∠E = 180°, then ∠D and ∠E are classified as what kind of angles?

Archy [21]

The other person is literally wrong. The answer is D. Supplementary because two angles that add up to 180 are supplementary angles.
