Answer:
Axis of symmetry for the functions f(x) and h(x) are x = 4 and x = -2 respectively.
Step-by-step explanation:
Function f(x) = -2(x - 4)² + 2
Vertex of the graph → (4, 2)
Since line of symmetry of the graph is defined by the x-coordinate of the vertex.
Therefore, x = 4 will be the line of symmetry of the function 'f'.
Second function 'h' has been given in the graph.
Vertex of the function from the graph → (-2, 2)
Therefore, line of symmetry will be x = -2
Answer:
BC = 17.2.
Step-by-step explanation:
Since CAB = 90º, this is a right triangle.
The triangle format is given below:
C
A B
We have that AB = 8.6, and angle B measures 60º.
Length of BC:
BC is the hypotenyse.
Side AB is adjacent to angle B = 60º.
In a right triangle, angle 
, it's adjacent side with length s and the hypotenuse h are related by the cosine of the angle, that is:
In this question, we have an angle of 60º, with has cosine 0.5. We also have that side AB = s = 8.6, and the hypotenuse h is side BC. So
BC = 17.2.
Answer:
Step-by-step explanation:
$5.25 x 3 = $15.75
$15.75 + $9.50 = $25.25
X-1/(x+2)(x-2)^3(x+1) is the answer.
I hope this helps. :)
Number one is B Number two is also B
