A Google or Bing search box can be your friend, if you don't have a calculator with inverse trig functions. Most calculators that have trig functions also have the inverse functions, usually after a 2nd or "shift" key. Often, there is a mode setting for degrees or radians.

arcsin(0.33) ≈ 19°
arccos(0.47) ≈ 62°
arctan(1.21) ≈ 50°
arcsin(0.82) ≈ 55°

2. The number of atoms of a particular chemical element is modelled by
____ [38]

9514 1404 393

Answer:

  a) 600

  b) see below

  c) 1.26 hours

Step-by-step explanation:

a) The value of y when x=0 is the coefficient of the exponential term:

  y = 600·3^(-0) = 600·1 = 600

There were 600 atoms to start.

__

b) see attached for a graph

__

c) The graph shows 150 atoms at t = 1.26, about 1.26 hours after the start of time counting.

If you want to find that value algebraically, substitute for y and solve for x. Logarithms are involved.

  150 = 600·3^(-x)

  150/600 = 3^(-x)

  log(1/4) = -x·log(3)

  x = -log(1/4)/log(3) = log(4)/log(3) ≈ 1.2618595

After about 1.26 hours, there were 150 atoms.

Answer:

  a) 7/10

  b) 1/6

Step-by-step explanation:

a) There are 10 ways to roll a 5 or less. Of those, 7 are greater than 3.

(die 1)(die 2) ∈ {11, 12, 21, 13, 22, 31, 14, 23, 32, 41}

  p(>3 | ≤5) = 7/10

__

b) Of the 36 possible outcomes of rolling two dice, there are 6 ways to have a 6 and an odd number:

  {16, 36, 56, 61, 63, 65}

The probability of interest is 6/36 = 1/6.
