4. Consider the building from the figure below. a) If it is 200 feet tall and you are 20 feet away, at what angle from the ground will you have to tilt your head to see the top of the building? (For simplicity assume that your head is even with the ground.) b) How far is it from your head to the top of the building? c) Repeat parts (a) and (b) assuming your head is NOT even with the ground, but is 6 feet above ground level. And

13. Write a MATLAB program to plot the curve of the equation 3*sin(2x)*cos(2x). The range of x is [0,2*pi].

Question 2 A rocket is launched vertically. At time t= 0, the rocket has reached an altitude of h0=500 m and is rising at a velocity of v0=125 m/s. The height of the rocket as a function of time is given by: h = -t2 + v0 t + h0 (a) Create a MATLAB function that returns the height of the rocket as a function of time. (b) Plot the height versus time from 0 to 30 seconds with an increment of 0.2 s. (c) Use the ginput command to find the time when the rocket starts to fall back to the ground and the time when it hits the ground. Use formatted output command to display the results as follow: "the rocket starts to fall back at t = .." "the rocket hits the ground at t =..." In MATLAB function codes

Use Matlab to Plot the graph shown in image 2 using data in table on image 1, BMI= W*H Where W is the weight in kilograms and H is the height in meters. Or the four color curves, use the line width ‘3’. To display a BMI of a person use the following: circular MarkSize ‘8’, MarkerEdgeColor ‘cyan’. To display this you have to enter two values. these are the Height in meters and Weight in kilograms. And inform the outcome results to the person from the command window.
