(f) Use your model to predict the best fuel efficiency (minimum fuel consumption) and the speed at which this occurs. 73 Sequences and series $2500 is invested in an account paying an annual interest rate of 5.6%. 160==5110 00 7, voe b 1R R IBl e 18 18,131147 25,100 19:310:05;,9.95,9.85, 9.75, % 20. (d) Since wind speeds above 20 m s~ are strong enough to cause damage to the turbine, that should be the upper limit for our domain, and since negative wind speeds are unrealistic, a reasonable domain is 0 < V < 20 310 We often use models to find optimal solutions. 1. . (d) From the graph we can see that the horizontal asymptote is a = 0 Figure 2.8 GDC screen for the solution to Example 2.4 (c) (e) From part (d) we can deduce that after a long period of time, the activity of the substance tends to zero. Find f(f) and estimate the percentage of renewables in 2020. 1% of 9999 900 is 99 999. Assume that only 100 people in the whole country have the disease. An even number is 2 times a whole number. 335 Modelling real-life phenomena 3. Use of the formulae for the n th term and the sum of the first n terms of the sequence. (b) Revise your model so that the reflector is at the bottommost position at timet =0 (c) Revise your model so that the reflector is at the rightmost position at time t = 0 (d) Revise your model for a point on the outer edge of the wheel.

The statement John is married is definitely either true or false. There is another method of measuring angles that is more natural. It seems fair to say that the mathematics did really come first here. The simplest Japanese kokeshi (wooden doll) is formed from a sphere (head) on top of a cylinder (body). (@ 6+6i (b) 2/3 + 61 (0 13i 7. . Case 1 The side opposite the known angle is too short to produce a triangle: For an SSA diagram to produce exactly one solution, the length a must be exactly the same length as the height or it must be longer than side c. Since the height of the triangle is i = sin A, this requires a = csinA ora > Case2 The side opposite the known angle produces two possible solutions: Figure4.9 Case | B 7 The two possible triangles are AABC and AABC Two triangles are produced if a is longer than the height and shorter than side c. Hence, two triangles are produced only if csin A =h>+ b2 2bx + x? Example 9.9 The position of a certain Formula One race car on a straight track can be modelled by the piecewise function sit) = 728, 3471 + 556t +a, 97.2(t 6) + b, 0=t x= 30.5 Therefore the coffee temperature will be within 3 significant figures of room temperature after 30.5 minutes. For example, finding the 100th term in the sequences in Example 3.8 would be laborious, using the recursive formula. It is a human creation. The first has a resistor with R, = 80 Q and an inductor with X; = 60 , while the second has a resistor with R, = 12Q and a capacitor with X, = 5Q. Sarah buys a car for $14,900. What shape will this distribution take? Experiment with different values of b to see how the graph changes. All DP mathematics courses serve to accommodate the range of needs, interests and abilities of students, and to fulfill the requirements of various university and career aspirations. 4, R A farmer, F, uses a tractor to travel to his house, H. The tractor can travel at a speed of 25 km per hour on roads but only at 15 km per hour over fields. Number and Algebra 2. Include units in your answer. The rate of growth of prey is assumed to be a constant proportion A of the population. As a precaution, a test has been developed to detect whether particular individuals have the disease. Express each rational expression in a + bi form. They talk about mathematical objects as though they had an existence independent of us and that we are accountable to mathematical truths in the same way as we are accountable to physical facts about the universe. Typically in chess, a move involves the movement of only one piece. Hence, the bird is at B(30 - %, 60 - %, 20 118 %) = B(ZO, 40, %) i A cuboid measuring 10 cm x 12 cm x 20.cm is cut into a rectangular pyramid, keeping the face that is 12 cm x 20 cm as its base and 10 cm as its height. (a) V(4, 3), W(=2,5) (b) K(3, 1), L(1,7) (c) T(6,7), G(2, 8) 3. Notice that starting the model with too great a population of prey could end up with an extinction of predators (Figure 2) because the very high prey numbers leads to overpopulation of predators for whom there is not enough prey left to eat. Compound interest is interest calculated both on the initial investment and also on interest already paid. 18, 12 12,8, 1632 rE LS8, 20,07 5=81,00 13035 6,12, 18 21527 = 1 10. Using the symmetry shown in Figure 5.19, we can then evaluate the values for the other three angles: 140 sin (135) = Q sin (225) = 7 sin (315) = = cos(135) = -22 cos (2259 = Y22 cos (3157 = 422 tan(135) = 1 tan(225) = 1 tan (315) = 1 2 2 Note that whether the value ofa trigonometric function for a given angle is positive or negative depends on which quadrant the terminal side of theangle ~ isin, because the signs ofx; y, or- change in each quadrant. Since 2000, the renewables consumption percentage has been growing at a rate given by f/(t) = 0.42 + 0.1062 0.00747t> where t is years after 2000. 8.
