Question 1 (5 points). Fill in the blanks. No arguments are necessary, final answers only. Consider the following right triangle: 960 a 8 cm C 3 10 Imagine that the length of a (measured in centimetres) is growing. We are wondering how fast is changing. Which unit do you want to measure 0 in? c = 9 + b Theta is measured by degree dd Find a formula that relates 0 and a: 9 + 0 dx de at = +62 c = a +b. 2/018 Hozo/9=-86=8 2 +(8)2 20+16=0 2-14 2 =-8 = 2a + 2b - 29+ 2(8) 29=-16 2 Express the rate of change of 0 in terms of the rate of change of a: B de dt 20+2bce) If a expands at a rate of 1cm, at what rate does change when a = 15 cm? S C = 6
