Answer:

∠ 1 = 24°

Step-by-step explanation:

∠ WXZ = ∠ WXY + ∠ YXZ , that is

72° = ∠ 1 + 2∠ 1 = 3∠ 1 ( divide both sides by 3 )

24° = ∠ 1

The distance between the two points rounding to the nearest tenth (-8,-6) and (-3,-4)

Lesechka [4]

Answer:

5.4

Step-by-step explanation:

To find the distance between two points, $(x_1,y_1)$ and $(x_2,y_2)$ , plug them into the following equation:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}$

Two negatives make a positive

$d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4$

Therefore, the distance between the two points rounded to the nearest tenth is 5.4.

I hope this helps!

I need help writing the first 5 terms of the sequence!

Angelina_Jolie [31]

The first five terms of the sequence are 1, 4, 7, 10, 13.

Solution:

Given data:

$a_{1}=1$

$a_{n}=a_{n-1}+3$

General term of the arithmetic sequence.

$a_{n}=a_{n-1}+d$ , where d is the common difference.

d = 3

$a_{n}=a_{n-1}+3$

Put n = 2 in $a_{n}=a_{n-1}+3$ , we get

$a_{2}=a_1+3$

$a_{2}=1+3$

$a_2=4$

Put n = 3 in $a_{n}=a_{n-1}+3$ , we get

$a_{3}=a_2+3$

$a_{3}=4+3$

$a_3=7$

Put n = 4 in $a_{n}=a_{n-1}+3$ , we get

$a_{4}=a_3+3$

$a_{4}=7+3$

$a_4=10$

Put n = 5 in $a_{n}=a_{n-1}+3$ , we get

$a_{5}=a_4+3$

$a_{5}=10+3$

$a_5=13$

The first five terms of the sequence are 1, 4, 7, 10, 13.
