Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) =

=
Answer:
C.
Step-by-step explanation:
Is it D? if not i’m so sorry
Shifts:
Shifted three units right and two units up to match the blue parabola
Stretches:
It doesn't have any stretches
Symmetry:

x and y intercepts:
x intercpets: It has no x-intercepts
y-intercepts: (0, 11)
<h2>
Explanation:</h2>
The pattern of the quadratic function is:

Whose graph is shown below as the red parabola.
So here we need to identify some characteristics of:

Whose graph is shown below as the blue parabola.
As you can see, the blue parabola is a transformation of the red parabola. The rule is as follows:
- The red parabola has been shifted three units right and two units up to match the blue parabola.
This is so because, for any function:

We have the following transformations:

On the other hand, the blue graph has neither stretches nor x intercepts. Finally, its axes of symmetry is
. The y-intercept is (0, 11) is indicated in the figure.

Answer:
3m cube
Step-by-step explanation:
l = 2m
b= 3m
h= 50cm --->50/100m----->0.5m
volume of cuboid = lbh
2 x 3x 0.5 = 3m cube
