ANSWER

$0,2,4,6,8,...$

EXPLANATION

An arithmetic has a constant difference .

We check to see which of the given sequences has a constant difference.

0,2,4,6,8,... has a constant difference of

$d=2-0=4-2=6-4=8-6=2$

hence it is an arithmetic sequence.

1,2,4,8,... is not an arithmetic sequence because there is no constant difference.

$2-1 \ne4-2.$

1,4,8,13,... is also not an arithmetic sequence because there no constant difference.

$4 - 1 \ne8 - 4$

The first option is correct.

Answer:

0,2,4,6

Step-by-step explanation:

This sequence is arithmetic because the same number is being added each time: 2. With the others, the number being added changes every time.

Answer:

Step-by-step explanation:

since it is <= we know that it is including the possibility of being equal so it is not a dotted line leaving only A and B as options. since its is <= it must be on the as the x increases the y must decrease. so the answer is A.

Radius of inscribed circle of triangle HJK is 6 unit

Step-by-step explanation:

As shown in figure,

The triangle HJK has In-circle or inscribed circle of radius PL(or PM or PN)

Since, PL and PM is radius of same in-circle,

PL = PM

Given that PL=3x+4 and PM =6x-14

3x+4=6x-14

3x=18

x=6

Thus, The correct answer is B). 6

Find X Options: 6 4 square root 6 6 square root 146

elena-14-01-66 [18.8K]

For this case we can apply the Pythagorean theorem to find "x". Taking the rectangle triangle of base 5 we have:

$x = \sqrt {11 ^ 2-5 ^ 2}\\x = \sqrt {121-25}\\x = \sqrt {96}\\\x = \sqrt {4 ^ 2 * 6}$

By definition of power properties we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$x = 4 \sqrt {6}$

Answer:

$x = 4 \sqrt {6}$

FYI - 14,15,16 are correct.

17. a) 7 (nearest integer), b) 6.8 (nearest tenth)

18. a) 14 (nearest integer), b) 13.8 (nearest tenth)

19. $\sqrt{40}$ --> simplified to = 2 $\sqrt{10}$

-- let me know if you have any questions regarding this.
