i need helppppppppppppppp
Step-by-step explanation:
Answer: or, as a decimal, 11.7.
Step-by-Step Explanation:
1. Use the <em>distance formula</em> and substitute the values of the two ordered pairs.
...
2. <em>Multiply</em> -1 by -4.
...
3. <em>Add </em>2 and 4.
4. Raise 6 to the <em>power of 2</em>.
...
5. <em>Multiply </em>-1 by -8.
6. <em>Add</em> 2 and 8.
7. Raise 10 to the <em>power of 2</em>.
...
8. <em>Add </em>100 and 36.
9. <em>Rewrite</em> 136 as 2² · 34.
10. After factoring 4 out of 136 and rewriting as ... , <em>pull out terms from under the radical</em>. It should look like this now: . That is your final answer!!
Hope that helps! Note: the unrounded decimal is 11.66190378.

Answer:
Angle a = 17°
Angle b = 17°
Step-by-step explanation:
Angles a and b are vertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Vertical angles are angles that are equal to each other
Step 1
We find x
a = b
Hence,
8x+1 = 21-2x
Collect like terms
8x + 2x = 21 - 1
10x = 20
x = 20/10
x = 2
Step 2
We find each angle
Angle a
8x+1
x = 2
Angle a = 8(2) + 1
= 17°
Angle b
21-2x
x = 2
21 - (2 × 2)
= 21 - 4
= 17°
Therefore:
Angle a = 17°
Angle b = 17°
I think it is A. Just count it up and formulate it into function notation.
Hope I helped! Merry Christmas :P
