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.

Step-by-step explanation:

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

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.

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°

Step-by-step explanation:

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.

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

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]
