Jada

> Let's draw some rectangles on it that get smaller and smaller to fit the remaining empty space. With enough rectangles we can come close to covering the whole blob.

> Jada, Geometry Unit 5, Lesson 4.3

**Jada** is good friends with Mai. She is also dating Noah, but she cheated on him with Andre at some point, although he never found out about it. Jada is also friends with Elena and Tyler.

The only other known details about Jada are that she likes to travel and that she has a younger cousin, whom she helps with his math homework.

Jada's favorite subject is physics.

## Notable Appearances

**Geometry Unit 4**

* "Jada is visiting New York City to see the Empire State building. She is 100 feet away when she spots it. To see the top, she has to look up at an angle of 86.1 degrees." (Lesson 8, Practice Problems)

*Analysis: This may imply that Jada likes to travel.*

**Geometry Unit 5**

* "Andre says, 'We know that if a rectangle is dilated by a scale factor of *k,* the area scales by a factor of *k^2.* Does this apply to other shapes?' Jada says, 'Here's a shape that's not a rectangle. Say its area is A square units. Let's draw some rectangles on it that get smaller and smaller to fit the remaining empty space. With enough rectangles we can come close to covering the whole blob.' Andre says, 'These rectangles start to make a nice approximate of the blob. If we wanted to get closer, we could add even more rectangles. The sum of the areas of all the rectangles would add up to the area of the blob! I think we're almost there!'" (Lesson 4.3)

*Analysis: Because Jada appears with Andre, who is infamous for having affairs, this may suggest that the two of them are having an affair.*

**Geometry Unit 7**

* "Jada and Andre want to share a big slice of pizza so that each of them gets the same amount, but Andre doesn’t like the crust. The pizza slice is a sector of a circle with a radius of 20 cm and a central angle that measures pi/3 radians." (Lesson 14.3)

*Analysis: The fact that Jada puts up with this supports the theory that they are having an affair.*

**Algebra 2 Unit 3**

* "Jada was helping her cousin with his math homework. He was supposed to solve the equation 8 + x = 5. He said, 'If I subtract 8 from both sides, I get x = 5 - 8. This doesn't make sense. You can't subtract a bigger number from a smaller number. If I have 5 grapes, I can't eat 8 of them!'" (Lesson 10.1"

*Analysis: Not only does this confirm that Jada has a younger cousin, but it also confirms that she likes helping him.*

**Algebra 2 Unit 6**

* "Jada, Noah, and Elena are riding a carousel. The carousel moves in a counterclockwise direction. When the ride begins, Jada is at position J, Noah is at position N, and Elena is at position E." (Lesson 18.2)

*Analysis: Confirms that Jada is friends with Noah and Elena, because they spend time together outside of school.*

* Jada begins the carousel ride at point J and Noah begins the carousel ride at point N. The radius of the carousel is 20 feet and it rotates in a counterclockwise direction, making one complete rotation every 10 seconds." (Lesson 18.3)

*Analysis: Reinforces the idea that Jada is friends with Noah.*

**Algebra 2 Unit 7**

* "For physics class, Jada wants to know how the surface of different ramps affects the maximum speed of a marble being rolled down the ramp." (Lesson 3, Practice Problems)

*Analysis: This implies that Jada likes physics class.*

## Miscellaneous Appearances

**Geometry Unit 1**

* "Jada wanted to construct a line perpendicular to line l through point C." (Page 51)

**Geometry Unit 2**

* "Jada and Tyler were playing the Info Gap, using Card 3. Tyler asked, 'Can I have 2 sides and an angle?' Jada told Tyler that one angle was 16, one side was 5 cm, and one side was 4 cm." (Lesson 4.3)
* "Diego, Jada, and Noah were given the following task: Prove that if a point is the same distance from A as it is from B, then C must be on the perpendicular bisector of AB. At first they were really stuck. Noah asked, 'How do you prove a point is on a line?' Their teacher gave them the hint, 'Another way to think about it is to draw a line that you know C is on, and prove that line has to be the perpendicular bisector.'" "Diego's approach: 'I drew a line through C that was perpendicular to AB and through the midpoint of AB. That line is the perpendicular bisector or AB and C is on it, so that proves C is on the perpendicular bisector.'" (Lesson 7, Practice Problems)
* "Jada says that it is square because folding it alongside the horizontal dashed line and the the vertical dashed line gives 4 congruent sides." (Lesson 8, Practice Problems)
* "Jada is learning about the triangle congruence theorems: Side-Side-Side, Angle-Side-Angle, and Side-Angle-Side. She wonders if there are any theorems like these for parallelograms." (Lesson 15.2)

**Geometry Unit 3**

* "Jada dilated triangle ABC using center P and scale factor 2." (Lesson 4.3)

**Geometry Unit 5**

* "Tyler and Jada wish to find the value of x, the length of side BC in this triangle. Tyler decides to set up the equation tan(56) = 8/x. Jada says she prefers an equation that has x in the numerator." (Lesson 4, Practice Problems)

**Geometry Unit 6**

* "Jada has this idea for bisecting angle ABC. First she draws a circle with center B through A. Then she constructs the perpendicular bisector of AD." (Lesson 7, Practice Problems)

**Geometry Unit 7**

* "Jada cuts out a rectangular piece of paper that measures 5 inches by 4 inches. Han cuts out a paper sector of a circle with radius 5 inches, and calculates the arc length to be 2pi inches." (Lesson 9, Practice Problems)
* Clare missed class and Jada is teaching her how to construct the circumscribed circle of a triangle. Here are the instructions Jada wrote. 'Construct all 3 perpendicular bisectors of the triangle’s sides. The point where the perpendicular bisectors intersect is called the circumcenter. Construct a circle centered at the circumcenter with radius set to the distance between the circumcenter and a vertex. If the triangle has a circumscribed circle, the circle you construct will go through all 3 vertices.'" (Lesson 13, Practice Problems)
* "Jada is finding the area of a sector with an angle pi/4 radians and radius 8 units. She found the area of the whole circle, then found the fraction represented by the sector by dividing pi/4 by 360. She multiplied this fraction by the total circle area." (Lesson 14, Practice Problems)

**Algebra 2 Unit 1**

* "Jada and Mai are trying to decide what type of sequence this could be: Jada says, 'I think the sequence is geometric because in the value column each row is 3 times the previous row.' Mai says, 'I don't think it is geometric. I graphed it and it doesn't look geometric.'" (Lesson 3.3)

**Algebra 2 Unit 2**

* "Jada used the diagram shown here to figure out that 2x^3 + 13x^2 +16x + 5 = (2x + 1)(x^2 + 6x + 5)." (Lesson 13.2)

**Algebra 2 Unit 3**

* "Jada was solving the equation √(6 - x) = -16. She was about to square each side, but then she realized she could give an answer without doing any algebra." (Lesson 9, Practice Problems)
* "Jada squared a number and got -4. Elena squared a different number and got -4." (Lesson 11, Practice Problems)

**Algebra 2 Unit 5**

* "Jada thinks changing the equation to J(t) = -62(0.85)^t + 75.1 makes a good model for the data. Noah thinks N(t) = -62(0.85)^(t-1) + 68 is better." (Lesson 3.3)

**Algebra 2 Unit 6**

* "Jada is riding on a Ferris wheel." (Lesson 18, Practice Problems)
