The answer is eyebrow. According to a research, the mean distance from
chin to nose was 6.96 cm. The mean distance from nose to eyebrows was
6.55 cm. The mean space from eyebrows to
hairline was 6.8 cm. while, the space from chin
to hairline was 20.3 cm.
Answer:
x = π/2, 7π/6, or 11π/6
Step-by-step explanation:
sin² x − cos² x − sin x = 0
Use Pythagorean identity to write cosine in terms of sine.
sin² x − (1 − sin² x) − sin x = 0
sin² x − 1 + sin² x − sin x = 0
2 sin² x − sin x − 1 = 0
Factor:
(2 sin x + 1) (sin x − 1) = 0
Solve:
sin x = -1/2 or 1
x = π/2, 7π/6, or 11π/6
Answer:
see below
Step-by-step explanation:
1. 2m = 24
Divide each side by 2
2m/2 = 24/2
m = 12
2. y – 9 = 30
Add 9 to each side
y-9+9 = 30+9
y = 39
3. X/4 = 12
Multiply each side by 4
x/4*4 = 12*4
x = 48
4. k + 12.5 = 30
Subtract 12.5 from each side
k+12.5-12.5 = 30-12.5
k =17.5
5. 3r = 15.3
Divide by 3
3r/3 = 15.3/3
r =5.1
Your answer is 85.555,hope this helped or 85.5 with - over it
The answer is: [B]: " 3.99 * 10⁻⁶ " .
______________________________________________
Note:
______________________________________________
We are given the following answer choices, and we are asked which one is the "smallest number" :
_______________________________________________
[A]: 4.4 * 10⁻⁵
_________________________________________
[B]: 3.99 ⋅ 10⁻⁶
______________________
[C]: 2.6 ⋅ 10²
______________________
[D]: 1.85 ⋅ 10³
_______________________
We can rule out answer choices: [C] and [D]; since these values, essentially "direct us" to move the decimal point FORWARD "2 places" and "3 places", respectively; whereas choices [A] and [B] essentially "direct us" to move the decimal point BACKWARD "5 places" and "6 places" respectively. Note that all values given in the answer choices are written in proper "scientific notation" —that is, beginning with a "single integer followed by (a) decimal point(s) and then additional digits (when needed). So, the answer choice that essentially "directs us" to move the decimal point BACKWARD "6 places" —
___________________________________________________
→ Answer choice: [B]: " 3.99 * 10⁻⁶ " ;

is the smallest value ; and as such, the correct answer.
