Answer
Domain of the function:
In interval notation: [6, ∞)
In set notation: {x: x∈R, x≥6}
Explanation
Remember that the the domain of the square root function are all the values such is is bigger than zero. We can express the later in set notation: {x: x∈R, x≥0}, or in interval notation: [0, ∞)
This is because the square root is not defined, in the real numbers, for negative values.
So, to find the domain of our function, we just need to set the thing inside the radical grater or equal than zero and solve for x:
The domain of the function is all the numbers bigger than 6, including 6.
Answer:
third option is the correct answer
go with the names of the triangle
the triangles are HIJ and LMN
so the ratios will be accordingly
Answer:
x=-14
Step-by-step explanation:
think the number is x
According to the question
x/7+12=10
=>x+84=70 (multiply both side by 7)
=>x=70-84
x=-14
6)
P of <span>Regular heptagon = 7a = 7 x 12 = 84
Area </span>of Regular heptagon = 1/2 P a
Area of Regular heptagon = 1/2 (84)(8)
Area of Regular heptagon = = 336
answer
B. 336
7)
P of Regular nonagon= 9a = 9 x 9 = 81
Area of Regular heptagon = 1/2 P a
Area of Regular heptagon = 1/2 (81)(16)
Area of Regular heptagon = = 648
answer
D. 648
7191
my guy you could just search that on the answers on on the web
