The negative in a = -2 for answer A represents a reflection over the x-axis.
What does the cosine graph usually look like?.....It goes through point (0,1) and decreases.
The graph shown goes through point (0,-2). Since there are no vertical or horizontal shifts, the graph has an amplitude of 2 and reflects over the x-axis.
a=2 for answer D does not represent the reflection over the x-axis.
I am not answering all the questions.
I will only do the first one.
A = pir^2
A = pi(6)^2
A = 36pi
You do the rest.
A+ 2/2= -1
⇒ A+ 1= -1
⇒ A= -1 -1
⇒ A= -2
Final answer: A= -2~
Answer:
Step-by-step explanation:
we know that
2 is a zero of multiplicity 3 of the polynomial
so
we have that
x=2 is a solution of the polynomial
A factor of the polynomial is
----> is elevated to the cube because is a multiplicity 3
and the other solution is x=-2
since the polynomial is fifth degree, x=-2 must have a multiplicity 2
so
the other factor of the polynomial is
----> is squared because is a multiplicity 2
therefore
The polynomial is equal to multiply the factors by the leading coefficient
so
