Answer:
12 - 2n
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = 8 - 10 = - 2, thus
= 10 - 2(n - 1) = 10 - 2n + 2 = 12 - 2n
Answer: 4/36 or 1/9
Step-by-step explanation: The answer will be 1/9 because when a dice is rolled 6 times, every number has a 1/6 chance of being the number. So if the die is rolled 36 times, the number will show up 1/9 of the time.
Answer: 1. 28 2. 25

Didn't know if you wanted the explanation or not, so sorry. But I can put an explanation if you need it.
For the given function, the domain is D : { x ≥ 7} and the range is R: { y ≥ 9}
<h3>
How to get the domain and range?</h3>
Here we have a square root, remember that the argument of the square root must be equal or larger than zero, so the domain is such that:
x - 7 ≥ 0.
Solving for x we get:
x ≥ 0 + 7
Then the domain is:
x ≥ 7
To get the range, we evaluate in the minimum of the domain:
f(7) = √(7 - 7) + 9 = 9
Then the range is the set of all values larger than 9, because the function is increasing.
So the range is R: y ≥ 9.
