Moment for Discovery SSS Theorem Via Kites and Darts Two geometric figures, the kite and dart, though elementary, are quite useful. The figures we have in mind are shown in Figure 3.26, where it is assumed that AB = AD and BC = CD. The dart is distinguished from the kite by virtue of the eight angles at A, B, C, and D involving the diagonals AC and BD being either all acute angles (for the kite), or two of...

(Discrete Math) Read the following combinatorial proof, and write a theorem that we proved. Explain it in details. We count the number of k+1 element subsets of [n+1]. On one hand, it is clearly C(n+1,k+1). On the other hand, we can count these subsets in two steps. First we count the subsets that contain the number n+1. Since have to choose another k elements from {1,2,...,n} for it to make a k+1-element set, the number of these is C(n,k). Then...

2) (i) State the converse of the Alternate Interior Angle Theorem in Neutral Geometry. (ii) Prove that if the converse of the Alternate Interior Angle Theorem is true, then all triangles have zero defect. [Hint: For an arbitrary triangle, ABC, draw a line through C parallel to side AB. Justify why you can do this.] 5) Consider the following statements: I: If two triangles are congruent, then they have equal defect. II: If two triangles are similar, then they have...
A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another, one in the x direction another in the y direction
A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another, one in the x direction another in the y direction. Both of these pieces fly away with a speed of V = 35 m/s. The third piece has three times the mass of the other two pieces. Part (a) Write an expression for the speed of the larger piece, that is in terms of only the variable V. Part (b) What is the numeric value for...

Two blocks of metal come into contact with one another. Given the following data: Block one Specific heat 0.091 kcal/(kg°c) Mass 0.19 kg Initial temperature-22 °C Block two Specific heat - 0.21 kcal/(kg°c) Mass = 0.161 kg Initial temperature 90 °C What is the final temperature (in °C) of the two blocks after they reach equilibrium? A: 50.5 | B: 53.2| C: 56.0 | D: 63.6 | E: 67.0 | F: 68.0| G: 70.3 | H: 112.0

Given two solar cells, one with a Vo 0.4V and Je 25mA/cm, and another cell with a Voc- 0.6V and Je 15mA/cm', find the new values of Voe and e when they are connected in a) parallel and b) series. Assume both solar cells follow the ideal diode equations. Hint: Try drawing the two different circuit configurations, you can extract some current relationships.

Two pumps connected in parallel fail independently of one another on any given day. The probability that only the older pump will fail is 0.25, and the probability that only the newer pump will fail is 0.15. What is the probability that the pumping system will fail on any given day (which happens if both pumps fail)? (Round your answers to four decimal places.) I had put 1/4 and 1/2 however these were proven to be incorrect?

12. Suppose you haven video streams that need to be sent, one after another, over a communication link. Streami consists of a total of b, bits that need to be sent, at a constant rate, over a period of t seconds. You cannot send two streams at the same time, so you need to determine a schedule for the streams: an order in which to send them. Whichever order you choose, there cannot be any delays between the end of...
