Lisa is writing a coordinate proof to show that the diagonals of a square are perpendicular to each other. she starts by assigni

ng coordinates as given. a square is graphed on a coordinate plane. the horizontal x-axis and y-axis is solid and grid is hidden. the vertices are labeled as k, g, h and j. the vertex labeled as k lies on begin ordered pair 0 comma 0 end ordered pair. the vertex labeled as g lies on begin ordered pair 0 comma a end ordered pair. the vertex labeled as j lies on begin ordered pair a comma 0 end ordered pair. one vertex is unlabeled. diagonal k h and g j are drawn. drag and drop the correct answers to complete the proof. since ghjk is a square, the coordinates of h are (a, ). the slope of kh¯¯¯¯¯¯ is . the slope of is −1 . the product of the slopes of the diagonals is . therefore, kh¯¯¯¯¯¯ is perpendicular to gj¯¯¯¯¯ . 10−1agj¯¯¯¯¯gk¯¯¯¯¯¯

Your a cheater, k12 will expel cheaters..... jk lol but the answers are

Since GHJK is a square, the coordinates of H are (a, a).
The slope of KH¯¯¯¯¯¯ is 1.
The slope of GJ¯¯¯¯¯ is −1 .
The product of the slopes of the diagonals is −1.
The product of the slopes of the diagonals is −1.

Good luck, and really study, because the finals test will be difficult, and use the geometry reference guide.... It covers the fundamentals

Jose has $45 to spend at the mall. He buys a toy for $18.63, two candy bars at $0.47 EACH, and a shirt for $12.64 (All prices in
GREYUIT [131]

Answer:

$12.79

Step-by-step explanation:

$45 - $18.63 = $26.37

$26.37 - ($.47 x 2) = $26.37 - $.94 = $25.43

$25.43 - $12.64 = $12.79

Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circ
RSB [31]

Answer:

146°

Step-by-step explanation:

Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle. Given m arch AB=64° and ⦣ABC=73°, m ⦣ABC=__ ° and m arch AC=__ °.

Solution:

Given that:

arc AB = 64° and ⦣ABC=73°

The Central Angle Theorem states that the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points. The inscribed angle is any point along the outer arc AB and the two points A and B.

Therefore arc AC is the central angle of ⦣ABC. Using the central angle theorem gives:

arc AC = 2 * ⦣ABC

substituting:

arc AC = 2 * 73

arc AC = 146°

What is the range for y=x^2-7x-8 ?
gtnhenbr [62]

Answer:

[-20.25;+∞).

Step-by-step explanation:

1) according to the properties of the given parabola the minimum is:

x_0=-\frac{-7}{2}=3.5; \ y_0=-20.25;

2) y₀=-20.25 means, the value -20.25 is minimum of the range, the maximum →+∞;

3) finally, the range y≥-20.25.
