5. The table below represents a quadratic function: draw a graph plot points
What would be the axis of symmetry for the equation?
What is the vertex?
What are the roots?
What is the y-intercept?
Answer:
The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Find the value of the expression 12y - 2xy, when x = 5 and y = 10.
Answer:
12y-2xy
x=5, y=10
(12x10) -(2x5x10)
=120-100
=20
Step-by-step explanation:
1.first collect the information you have been given in the question to make answering of the question easy.
2.then substitute the x value (in this case 5) and the y value (10) into the expression 12y - 2xy on there respectful positions.
3.having done so, you can then multiply and thereafter subtract as the question requires you to do.
Note: only substitute the y and x values where y and x appear in the question.
Always start with multiplying, after substituting,before subtracting or adding.
Suppose that a piano costs $5,000 and loses 20% of its value each year. What will be the value of the piano after 16 years? A. $219.90 B. $274.88 C. $140.74 D. $175.92
Based on the information given will be the value of the piano after 16 years is : C. $140.74.
Using this formula
Time=Principal(1-rate)^n
Where:
Principal=$5,000
Rate=20%
Number of year=16 years
Let plug in the formula
Time=5,000(1-0.20)^16
Time=5,000(.80)^16
Time=$140.737
Time= $140.74 (Approximately)
Inconclusion the value of the piano after 16 years is : C. $140.74.

X =?
y =?
Answer:
x=1/3
y=-7
Step-by-step explanation:
using the elimination method, you can add both equations vertically, to eliminate the x
-3x+y=-8
3x+2y=-13
3y=-21
y=-7
we then fix the value of y into the first equation
-3x+y=-8
-3x-7=-8
-3x=-8+7
-3x=-1
x=1/3

Find the measure of angle TUY
Answer:
120
Step-by-step explanation
Exterior angle theorem:
d = a + b
d = 70 + 50
d = 120
Answer: TUY: 120°
Step-by-step explanation:
Hello,
1. Recall that the sum of a triangle’s angles is 180°, regardless of the type of triangle.
2. Find TUS, that is, the angle for U.
U = 180°-(50°+70°)=60°
For TUY:
Knowing that U=60° and that the line above U is 180°:
180°-60°=120°
Find the length of the third side. If necessary, round to the nearest tenth. 16 23
Answer:
[tex]\sqrt{273}[/tex] units
Step-by-step explanation:
Use the Pythagorean Theorem: a^2 + b^2 = c^2
you have that a = 16 and c = 23, so:
16^2 + b^2 = 23^2
256 + b^2 = 529
b^2 = 273
b = [tex]\sqrt{273}[/tex]

The student's shadow was 5 feet long. At the same time, the shadow of the telephone pole was 18 feet 9 inches long. How tall is the telephone pole?
Please help
Answer:
19.9875 feet
Step-by-step explanation:
The formula is given as:
Shadow of the student/Height of the student = Shadow of the telephone pole/Height of the telephone pole.
1 inch = 0.0833 feet
Shadow of the student = 5ft
Height of the student = 5 feet 4 inches
4 inches to feet
= 4 × 0.0833 feet
= 0.33 feet
Hence: Height of the student = 5 + 0.33 = 5.33 feet
Shadow of the telephone pole = 18 feet 9 inches long
9 inches to feet
= 9 × 0.0833 feet
= 0.75 feet
Hence: Shadow of the telephone pole = 18 + 0.75 = 18.75 feet
Height of the telephone pole= x
Therefore:
5/5.33 = 18.75/x
Cross Multiply
5x = 5.33 × 18.75
x = 5.33 × 18.75/5
x = 19.9875 feet
The height of the telephone pole = 19.9875 feet
