The measure of angle XYZ in the parallelogram is: 71°.
What are the Opposite Angles of a Parallelogram?In a parallelogram, the angles that are opposite each other are congruent.
Find m∠XWZ using the triangle sum theorem:
m∠XWZ = 180 - m∠WXZ - m∠WZX
m∠XWZ = 180 - 81 - 28
m∠XWZ = 71°
m∠XWZ = m∠XYZ [opposite angles are congruent]
m∠XYZ = 71°

If m < 0 and b > 0, the graph of y = mx + b does not pass through which quadrant?
Quadrant I
Quadrant II
Quadrant III
Quadrant IV
Answer: Quadrant III
Step-by-step explanation:
The slope is negative and the y-intercept is positive.
This means that it is impossible for both x and y to be negative, and thus it does not pass through Quadrant III

Brandon is a running back for his local high school football team. In the last game, he carried the ball 8 times. In the first 5 carries, he gained 6 yards, 12 yards, and 4 yards before losing 2 yards and then losing additional yards. His last 7 carries combined for yards. What was his total net yardage for the game?
Using it's concept, it is found that Brandon's net yardage for the game was of 26.
How to find the net yardage?The total net yardage is the sum of all the yardage they gain, that is, the positive gains are added with a plus signal, while the negative gains are added with a negative signal.
Hence, his net yardage, considering that he gained 20 yards on his last 7 carries, is given by:
6 + 20 = 26.

The diameter of the sphere is 14 cm.
What is a sphere ?Sphere is a three dimensional object , it has no edges or vertices and is round in shape.
The surface area of the sphere is given by 4πr²
As radius = diameter /2
Surface area = 4π r²
196 π = 4π *(d/2)²
196/4 = d²/4
49 *4 = d²
d = 14 cm

If the diagonal of the rectangle is 10.5 inches and the length of the rectangle is 7.25, what is the width of the rectangle?
Answer:
w≈7.6in
Step-by-step explanation:
L= 7.25
D= 10.5
Using the formula [tex]d=\sqrt{w^{2} + l^{2} } \\[/tex]Solving for w [tex]w=\sqrt{d^{2} -l^{2} }[/tex] [tex]\sqrt{10.52^{2}-7.25^{2} } = 7.59523in[/tex]Answer:-
The width of this rectangle is = 7.59
Given:-
In this question, it is given that -
The diagonal of this rectangle is = 10.5
the length of this rectangle is = 7.25
To find:-
We have to find the width of this rectangle.
Solution:-
We can easily solve this problem using the Pythagorean theorem.
In this problem, it is given that the length of this rectangle is = 7.25 and the diagonal is =10.5
so by the Pythagorean theorem, we can get-
(length)² + (width)² = (diagonal)²
or, (7.25)² + (width)² = (10.5)²
or, (width)² = (10.5)² - (7.25)²
= 17.75 × 3.25
= 57.6875
or, width = 7.59
So, the width of the rectangle is 7.59.

Answer:

Step-by-step explanation:
Let the number be z
2 more than 3 times z ==> 3z + 2
6 less than 4 times z ==> 4z - 6
Product of the above two is
[tex](3z + 2) (4z - 6) \\= (3z)(4z) + (3z)(-6) + (4z)(2) + (2)(-6)\\= 12z^{2} -18z + 8z - 12\\= 12z^{2} -10z -12[/tex]
A rectangle has perimeter 16 m. Express the area A (in m2) of the rectangle as a function of the length, L, of one of its sides.
The area A of the rectangle as a function of the length, L of one of its sides is A = 8L - L²
What is the perimeter of a rectangle?The perimeter of a rectangle is P = 2(L + W) where
L = length of the rectangle and W = width of the rectangleGiven that P = 16 m,
P = 2(L + W)
16 = 2(L + W)
16/2 = L + W
L + W = 8
So, W = 8 - L
What is the area of the rectangle?
The area of the rectangle, A = LW where
L = length of the rectangle and W = width of the rectangleSince W = 8 - L, substituting W into the equation for A, we have
A = LW
A = L(8 - L)
A = 8L - L²
So, the area A of the rectangle as a function of the length, L of one of its sides is A = 8L - L²

&8x^2 - 32x + 32 \\
&25x^2 - 30x - 9 \\
&x^2 - 14x + 196
\end{align*}$
Answer:
Step-by-step explanation:
The quadratic expression having repeated root is 8x² - 32x + 32.
What are Quadratic Expressions?Quadratic expressions are polynomial expressions of second degree.
The general form of a quadratic expression is ax² + b x + c.
We have to find the root of each quadratic expression.
-x² + 18x + 81 = 0x² - 18x - 81 = 0
Discriminant = [tex]\sqrt{(-18)^2-(4*-81)}[/tex] = [tex]\sqrt{648}[/tex]
x = (18 + √648) / 2 or x = (18 - √648) / 2
Distinct roots
3x² - 6x + 9x² - 2x + 3
Discriminant = [tex]\sqrt{(-2)^{2}-(4*3) }[/tex] = [tex]\sqrt{-8}[/tex]
x = (2 + [tex]\sqrt{-8}[/tex]) / 2 or x = (2 - [tex]\sqrt{-8}[/tex]) / 2
Distinct roots
8x² - 32x + 32
x² - 4x + 4Discriminant = [tex]\sqrt{(-4)^{2}-(4*4) }[/tex] = 0
x = (4 + 0)/ 2 or x = (4 - 0) / 2
x = 2 or x = 2
Repeated roots
Hence the quadratic expression having repeated roots is 8x² - 32x + 32.

Step-by-step explanation:
given the equation of a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = 3x² - 4x + 3 ← is in standard form
with a = 3 , b = - 4 , then
