Useful Log Rules:

  • log(A*B) = log(A)+log(B)  .......... log rule 1
  • log(A/B) = log(A) - log(B) .......... log rule 2
  • log(A^B) = B*log(A)  ................... log rule 3

=========================================================

Part (a)

All logs shown below are base 3.

log(500) = log(5*100)

log(500) = log(5*10^2)

log(500) = log(5)+log(10^2) .... use log rule 1

log(500) = log(5) + 2*log(10) .... use log rule 3

log(500) = 1.4650 + 2*2.096 ....... substitution

log(500) = 5.657

<h3>Answer: 5.657</h3>

=========================================================

Part (b)

All logs shown below are base 3.

log(2) = log(10/5)

log(2) = log(10) - log(5) .... use log rule 2

log(2) = 2.096 - 1.4650  ....... substitution

log(2) = 0.631

<h3>Answer: 0.631</h3>

Write an equation in point slope form of the line through point J(4,1) with slope -4
lara [203]

Answer:

y - 1 = -4(x - 4)

Step-by-step explanation:

The point-slope form looks like y-k = m(x-h), where (h,k) is a point on the line and m is the slope.

Here,  y - 1 = -4(x - 4).  This is in point-slope form.
