Answer:
13
Step-by-step explanation:
The given expression is (3-2i)(3-2i)
This is of the form (a-b)(a+b)
This is equivalent to , where a = 3 and b=2i
=
=
But
=
=
=
Hence the value of the expression (3-2i)(3-2i) is 13.
Which is the graph of y = cos(x) + 3?
1 answer:
Answer:
On a coordinate plane, a cosine curve has a maximum of 4 and a minimum of negative 2.
Step-by-step explanation:
Given:
To find: maximum and minimum of the cosine curve
Solution:
A coordinate plane is a two-dimensional plane formed by the intersection two axis: x-axis and y-axis.
These two axes are perpendicular to each other.
As per the image drawn below,
a cosine curve has a maximum of 4 and a minimum of negative 2 on the coordinate plane.
