Area of a sector As in section 5.1, the area of a sector is a fraction of the area of the entire circle (a pizza slice). In general, suppose that the values of a particular independent variable, for example, x, determine the values of a dependent variable y in such a way that for a specific value of x, a single value of y is determined. Humanism sees mathematics as part of human culture and human history. is a function that is defined ona sequence of intervals. & 316, Yes since this is more than the price to be paid. For students taking their exams in 2021 there is a big change to the IB syllabus there will now be 4 possible strands: IB HL Analysis and Approaches, IB SL Analysis and Approaches, IB HL Applications and Interpretations, IB SL Applications and Interpretations. (b) Find the difference in height between low tide and high tide. Therefore, the cubic model for this turbine is P =0.297AdV? y 7. (b) 8memhr! As the value of x increases, the value of y also increases and there is no limit on how largey can become. ), then we can calculate the relative loudness in decibels, 1, using the formula nes) = lologm( 10:2) The number 10~!2in the formula represents the threshold of human hearing. Determine the gradient of each line and state the gradient of a line perpendicular to it. Remember what the mean value of a function is and considering b = 12 and a = 1, then the mean temperature is modelled by s Tll J} oo, We use Trap. Features Lep flo= 203t = 5 hal. The full criteria for passing the IB DP are set out below and students need to be aware that a score of 24 points will not always guarantee a pass. A rope of length 81 metres is cut into n pieces of increasing lengths that form an arithmetic sequence with a common difference of d metres. Determine if each pair of lines is parallel, coincident, or intersecting. (b) Explain why f does not have an inverse function. The relationship between two quantities how the value of one quantity depends on the value of another quantity - is the key behind the concept of a function. Then the trigonometric functions can be defined as sing=y cosf=x %, tnf=2 x#0 Now we consider angles in other quadrants, like the other three angles that are 45 from an axis: 135, 225, and 315. Since can be anything in the interval [0, 300], scale the x-axis accordingly and then use the GDC Zero tool to find the value of for which T'= 0 Now we just need to interpret the results. Find the general solution of (x> y?

We are told that the test is 99% accurate so, of the 100 cases of the disease the test would show positive in 99 cases and negative in one. Solution Since the arc measures 150, we use that fraction of the circumference: Figure 5.5 Diagram for Example 5.3 L 150 =0Qq 360(2 57 X 3) 3)i= = > =7 7.85m (3 s.f) 1. are inverses by showing that: Af ') = xand f(fin) = x L = r faxt2)=a(ter2)-s=xt8-8=x f(4xs>:i(4x8>+2:x2+2:x This confirms thaty = 4x 8 andy = ix + 2 are inverses of each other. The methods mathematics teaching you have experienced reflects a Platonist or constructivist view of mathematics? B A Figure 4.12 Cuboid room A room is a cuboid with every pair of opposite faces parallel, and intersecting faces, perpendicular. We can see some evidence of that here, RS RRERERRE mine Figure 19.36 GDC screens for the solution to Example 19.12 821 Bivariate analysis (c) The initial velocity, when the rocket is launched, is vy = 46.4ms~'. 13" 2 27. 12. ) So you can get to the nth term by adding d to a,, (n 1) times. Theoretically, of course! You may also see two different options for the least-squares regression line: y=mx + band y=a+bx Mathematically, they are identical, but be careful to interpret them correctly: in the first, m represents the gradient and b represents the y-intercept. Given that log,y = 4log,x, find all the possible expressions ofy as a function of x. 50 7. The first term of an arithmetic sequence is 2 and the 30th term is 147. So this expression means the sum of all the terms a; where i takes the values from 1 to k. We can u also write _a; to mean the sum of the terms @, where i takes the values from =m m to n. In such a sum, m is called the lower limit and the upper limit. A 6 Q resistor and 8 Q) inductor are in the first loop, and a 6 Q) resistor and a 3 Q capacitor are in the second loop. 110 =b sinB Example 4.11 In the triangle ABC, A =42,a=6cm,and B = 63 Find: (a) angle C (b) side b (c) side c.
