Answer:
C
Step-by-step explanation:
Answer: 60/12 or 5
Step-by-step explanation: Find the reciprical of 2/12. That is 12/2. Then, multiply 5/6 and 12/2. 12x5 is 60 and 6x2 is 12.
So the equation of the red graph is already given to us: 
. I assume you meant the blue graph?
We can use the vertex form: 
, where 
is the vertex. (We can ignore 
because is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).
The vertex for 
is at 
on the coordinate plane. (4 left, 2 down)
Plug into the vertex form:
The double negative becomes a positive, and then you're done:
Answer:
13+2h
Step-by-step explanation:
The word "sum" can be related to "addition" and "13 and a number" is just "13" and an exponent.
Answer:
(1/2)a^n
Step-by-step explanation:
Let m represent the monomial. The problem statement tells us ...
... m^2 = (1/4)·a^(2n)
Taking the square root, we have ...
... √(m^2) = √((1/4)·a^(2n)) = (√(1/2^2))·√(a^(2n))
... m = (1/2)·a^(2n·(1/2)) = (1/2)·a^n
The monomial is (1/2)a^n.
