Cot(3x)=3^(1/2)

cot(x)= cos(x)/sin(x)

cot(3x)= cos(3x)/sin(3x)

look at a unit circle chart

find a value for cos that has sqrt(3) in it

which one will reduce so that the cos/sin will equal sqrt(3)?

pi/6 radians

now cot(3x) implies that x is one third this value

pi/18 is the answer

C because if the denominator equals x-2 that means that the horizontal asymptote happens at x=2. And because the numerator and denominator have the same degree then you divide leading coefficients to get the vertical asymptote at y=-2

Present value sura wiggle would like to make a single investment have 2.2 million at the time of her retirement in 28 years she
levacccp [35]

Answer:

if the annual interest rate is 7%, then you need to invest:

present value = future value / (1 + i)ⁿ

  • future value = $2,200,000
  • i = 7%
  • n = 28 years

present value = $2,200,000 / (1 + 7%)²⁸ = $330,884.87

if the interest rate is 15%, the you need to deposit a smaller amount:

present value = future value / (1 + i)ⁿ

  • future value = $2,200,000
  • i = 15%
  • n = 28 years

present value = $2,200,000 / (1 + 15%)²⁸ = $43,942.34
