Prove that the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
The roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k
The equation is given as:
x^2 + (1 - k).x+k-3 = 0
For an equation to have real root, then the following must be true:
[tex]b^2 \ge 4ac[/tex]
In x^2 + (1 - k).x+k-3 = 0, we have:
a = 1
b = 1 - k
c = k - 3
So, we have:
[tex](1 - k)^2 \ge 4 * 1 * (k - 3)[/tex]
Evaluate
[tex]1 - 2k + k^2 \ge 4k - 12[/tex]
Collect like terms
[tex]k^2 - 2k - 4k + 1 + 12 \ge 0[/tex]
[tex]k^2 - 6k + 13 \ge 0[/tex]
Using a graphing calculator, the value of k is all real numbers
Hence, the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

The surface area of this cube is 864 square yards. What is the value of q?
Answer:
Volume
=
512
cubic feet
Explanation:
A cube has
6
faces all with equal area.
If the total surface area of the cube is
384
sq.ft.
then each face has an area of
384
÷
6
=
64
sq.ft.
Each face of a cube is a square and if we denote the length of an edge as
E
then the area of a face (in this case
64
sq.ft.) is equal to
E
2
XXX
E

=
64
sq.ft.
XXX
→

The volume of a cube with edges of length

In this case

if XYZ ~ RST, find RS
Answer:
RS = 38
Step-by-step explanation:
20x - 12 = 18x + 12
2x = 24
x = 12
3(12) + 2 = 38
The value of the side of triangle RS is equal to 38.
What is the similarity?If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the sides of the triangle XYZ are, XY = 5x - 3, XZ = 60 and the sides of the triangle TR = 40, RS = 3x + 2.
The value of RS will be calculated as,
( 5x - 3 ) / ( 3x + 2 ) = ( 60 / 40 )
( 5x - 3 ) / ( 3x + 2 ) = ( 6 / 4 )
20x - 12 = 18x + 12
2x = 24
x = 12
RS = 3x + 2
RS = ( 3 x 12 ) + 2
RS = 36 + 2
RS = 38
Therefore, the value of the side of triangle RS is equal to 38.

Your friend is looking at laptops for
college, and is comparing the different
screen sizes. If a laptop has a height of 6
in and a diagonal of 17.5 in, use the
formula below to find the width of the
laptop screen. Round your answer to the
nearest tenths place
17.5 = √6² + w²
17.5² = 36 + w²
306.25 = 36 + w²
270.25 = w²
√270.25 = w
16.4392822 = W
= w = 16.44 in

Use 3.14 to approximate pi.
Enter your answer as a decimal to the hundredths place in the box.
___ m3
Answer:
602.88 cu ft.
Step-by-step explanation:
V = Bh where B is the area of the base, which is a circle in your problem.
Since the diameter is 8, the radius is 4.
So, B = [tex]\pi r^{2} = 3.14(4^{2} ) = 3.14(16) = 50.24[/tex]
V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank
60% of that volume is .60(1004.8) = 602.88 cu ft.
