Answer:
81 degrees
Step-by-step explanation:
Let
be the identity matrix. Then pick whatever matrix you like for
.
Mean is the same as average. Adding up all the amounts then dividing it by the number of amounts. In this case, we add up all the snowfall amounts and then we divide it by 10 ( the count or number of snowfall amounts).
In equation,
(13+19+16+23+11+18+14+26+13+16) / 10 = 16.9
Th answer is A. 16.9 inches.
Answer: D: s∈ (-∞, 3]
Step-by-step explanation:
When we have a function:
y = f(x)
The domain is the set of the possible values we can input in f(x).
In this case, we have:
y = √(3 - s)
Where our variable is s.
So we want to find the possible values of s we can input in that function.
Remember that if y is a real number, then we can not have a negative number inside the square root, because it will lead to an complex solution.
Then the argument of the square root needs to be equal to or larger than zero.
This means that:
3 - s ≥ 0
From this inequality, we can find the possible values of s, which will be the domain.
We need to isolate s.
3 ≥ s
This means that s needs to be smaller than or equal to 3.
Then the domain is:
D: s∈ (-∞, 3]
Answer:
Step-by-step explanation:
The vertex form of a parabola:
(h, k) - vertex
We have the vertex at (3, 2) → h = 3 and k = 2.
Substitute:
The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:
<em>subtract 2 from both sides</em>
Finally:
<em>vertex form</em>
<em>use (a - b)² = a² - 2ab + b²</em>
<em>use the distributive property</em>
<em>standard form</em>
