Answer:
- x=8, x=2
- no solution
- no solution
Step-by-step explanation:
For the equation ...
y = a(x -h)² +k
you can find the x-intercepts by setting y=0 and solving for x.
0 = a(x -h)² +k
-k = a(x -h)² . . . . . . subtract k
-k/a = (x -h)² . . . . . divide by a
±√(-k/a) = x -h . . . . take the square root
h ± √(-k/a) = x . . . . add h . . . . this is the general solution
__
So, for each of your problems, fill in the corresponding numbers and do the arithmetic. If (-k/a) is a negative number, the square root gives imaginary values, so there is "no solution".
1. x = 5 ± √9 = {5 -3, 5 +3} = {2, 8} . . . . the x-intercepts are 2 and 8
2. x = -3 ± √(-2) . . . . . . no solution; the roots are complex
3. x = 5 ± √(-8/4) . . . . . no solution; the roots are complex

A line code is a code used to transmit digital signal data over a transmission line. Common line encodings are unipolar, polar, bipolar, and Manchester code. NonReturn-to-Zero NRZ and Return-to-Zero technologies are used in unipolar, polar, and bipolar line coding schemes. Line coding is used to reduce bandwidth, reduce the chance of error, and increase efficiency. The purpose of this lab is to understand different types of row encoding, use MATLAB to implement row encoding functions, and use the input data to simulate those row encoding functions.

Answer:
A non-square rhombus is not a rectangle.
Step-by-step explanation:
A parallelogram is a quadrilateral (four-sided figure) that has two pairs of parallel sides.
A rectangle is a parallelogram with four right angles.
If a parallelogram does not have four right angles, then it is not a rectangle. However it is still a parallelogram, as it has two pairs of parallel sides.
