Answer:
I'm pretty sure the answer is A.
Step-by-step explanation:
A has the correct formula, all you have to do is plug in 8 for x. 1.03^8 = 1.26677008139. 1.26677008139 * 10 is 12.6677008139 which rounds up to 13.
I deeply apologize if that answer is wrong.

The average atomic mass is 6.92X
How do we compute the average atomic mass?
In a bid to calculate the average atomic mass, we multiply the fraction of each isotope by the mass number , then add them together.
This is more like weighted average, as shown below:
average atomic mass=(mass number of first isotope*fraction)+(mass number of second isotope*fraction)
average atomic mass=(6X*7.59%)+(7X*92.41%)
average atomic mass= 6.92X

Answer:
θ = 0.9626
Step-by-step explanation:
Hi there!
We're given the hypotenuse and the leg adjacent to θ in this right triangle. To find θ, we can use the cosine ratio:
Plug in the given information
Use the inverse cosine ratio
Plug this into your calculator (and ensure you're solving for radians instead of degrees in the settings)
Therefore, θ = 0.9626 when rounded to four decimal places.
I hope this helps!
Answer:
B and C
Step-by-step explanation:
To determine which ordered pairs are a solution, substitute the coordinate points into the left side of the inequality and check against right side for validity.
A (3, 5)
25 - 9 = 16 ≥ 7 ⇒ (3, 5) is not a solution
B (- 2, - 5)
- 25 + 6 = - 19 ≤ 7 ⇒ (- 2, - 5) is a solution
C (5, - 3)
- 15 - 15 = 0 ≤ 7 ⇒ (5, - 3) is a solution
