Answer:
The approximate age of the bone is approximately 11552 years.
Step-by-step explanation:
The current proportion of carbon-14 with respect to its original amount is defined by following formula:
(1)
Where:
- Current amount of carbon-14, no unit.
- Initial amount of carbon-14, no unit.
- Time, in years.
If we know that
, then the approximate age of the bone is:


The approximate age of the bone is approximately 11552 years.
Answer:
y = 2x - 5
Step-by-step explanation:
The slope for a parallel line is the same as the slope in the given equation. Therefore the slope of the new line will be 2 m= 2
use that slope and (2, -1) to find b
-1 = 2(2) + b
-1 = 4 + b
-5 = b
Plug m and b into y = mx + b
y = 2x - 5
Answer:
6.71
You use pythagoras so you do:
6² + 3² = 45
square root 45 =6.71
Option C:
x = 90°
Solution:
Given equation:

<u>To find the degree:</u>

Subtract 1 + cos²x from both sides.

Using the trigonometric identity:




Let sin x = u

Factor the quadratic equation.

u + 2 = 0, u – 1 = 0
u = –2, u = 1
That is sin x = –2, sin x = 1
sin x can't be smaller than –1 for real solutions. So ignore sin x = –2.
sin x = 1
The value of sin is 1 for 90°.
x = 90°.
Option C is the correct answer.
Answer:
y=[-2]x[+][5]
Step-by-step explanation:
m= -2
Using the point (1,3) Find the value of b
3= -2(1)+b
3= -2+b
