In a Triangle XYZ, side XY is congruent to YZ. If ≤ X=4x+60, < Y=2X+30 and < Z=14x + 30, find the measurements of the angle X, Y and Z.

Consider the sequence defined by b0 = 0, b1 = 1, b2 = 2, and bn = bn−1 + 2bn−2 − 2bn−3 for n ≥ 3. Determine the values of b3, b4, b5, b6, and a closed form expression for bn. (You will need to think about how to appropriately extend the type of closed form expression given above.)

8. Each student at the Crazy Education in Music Conversatory studies at least two of the following: circular breathing, square dancing, and triangle. Last year, 7 students studied all three, 50% of the students studied at least circular breathing and square dancing, 60% of the students studied at least circular breathing and triangle, and p% of the students studied at least square dancing and triangle. Determine all possible positive integer values of p. There should be a general formula as there are many possibilities of p

A 50 kg box slides down an inclined plane 8.3 m long and 4 m high. If the friction force between the box and the inclined plane is 112 N, what is the work done by the friction force?

2. We want to compute the area of the region between the line y = x − 1 and the parabola y2 = 2x + 6 We have two methods to calculate this one. For both methods, start by finding the points of interception and sketching the region. (a) Method 1. Solve for y on the equation y2 = 2x + 6. You will notice that there are two solutions. Look back at the graph. These correspond to the two branches of the parabola when we consider y as a function of x. Try to decompose your area as the sum of two areas that you can write as integrals. Be careful. (b) Method 2. Think of y as the variable and of x as a function of y

How long did it take for the beam to reach a speed of 22 m/s moving with friction covered a distance of 70 m? 3 m/s2 Bury the drum of the beginning of this movement too!

Solve the equation x+4=-12

Calculate the molarity of HCL in a reagent labelled 37.0 wt% HCL, density=1.188g/ml

Assume that the price per unit d of a certain item to the consumer is given by the equation d=35-10x where x is the number of units in demand. The price per unit from the supplier is given by the equation s=2x+20 where x is the number of units supplied. Find the equilibrium price and the equilibrium quantity.

The average salary of the employees in a certain organization is equal to 9300 with a standard deviation of 1400. It was decided to reduce 10% of each employee's salary and it was also decided to reduce another 100. What are the new average and standard deviation?

a student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of vO= 12.5 m/s. the cliff is h=38.0 m above a flat, horizontal beach as shown in the figure. (c) write the equations for the c- and y-components of the velocity of the stone with time. (use the following as necessary: t. let the variable t be measured in seconds. do not include units in your answer.) (d) write the equations for the position of the stone with time, using the coordinates in the figure. (use the following as necessary:t. let the variable t be measured in seconds. do not state units in your answer.)

Find the slope of the line through (1,1) and (x,y) for y=x^2+2 when: (Note: Ensure you carry enough significant digits in your calculation to arrive at an accurate answer.) x= 2.03 x=2+h
