<h3>
Answer: -1</h3>
=======================================================
Explanation:
First we need to find the slope of this given line.
The two points on here are (0,-3) and (3,0)
Apply the slope formula
m = (y2-y1)/(x2 - x1)
m = (0-(-3))/(3-0)
m = (0+3)/(3-0)
m = 3/3
m = 1
The slope of the given line is 1. The negative reciprocal of this is -1, which is the perpendicular slope.
Side Note: Any two perpendicular lines always have their slope multiply to -1, as long as neither line is vertical.
True, Every normal unitary operator u: x! x exists.
False, An if only if it is invertible, a matrix qualifies as unitary.
What is the matrix?
A group of numbers built up in a rectangular array with rows and columns. The elements, or entries, of the matrix, are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics.
Here, we have
a. Every unitary operator U:X→X is normal as an operator A is unitary if A*A = AA* = I and an operator is normal if A*A = AA*.
Hence, every unitary operator u: x → x is normal.
b. A unitary matrix is always invertible but an invertible matrix need not be unitary. An invertible matrix A is unitary if A⁻¹ = A*
Hence, it is not true.

Answer:
FC = 28
Step-by-step explanation:
The parallel lines creates two similar triangles:
ΔBDC similar to ΔEDF
Similar triangle means corresponding lengths are equal.
BD corresponds to ED
BC corresponds to EF
DC corresponds to DF
Now, we want to find FC, we let that length be "x",
thus we can write:
DE similar DF
DB similar DC
So,
Now, we use algebra, cross multiplication and solve for x, which is FC:
FC = 28
