Deepika can invest money at 6.5%/a compounded quarterly. She would like $15 000 in 7 years. How much does she need to invest now? 1. (K 1 Mark) X+1 Determine the value of the function f(x) => when x= 2. x-1 9. a) For the arithmetic series-200-180-160- -0, find the values of d, and n. b) Find the value of a given S-3280 and r=-3. c) Given S=3n+4n in a series, find t. (Hint: St +12+...+t-1+ t ) 13. (C 4 Marks) Determine the amplitude, the period, the phase shift, and the vertical shift of the function with respect to y= sinx. Graph at least one complete cycle that includes the y-intercept 9 f(x)=-sin 2 2 x+90 2 Deepika can invest money at 6.5%/a compounded quarterly. She would like $15 000 in 7 years.
