Here are the log properties you need:
log(ab) = log(a) +log(b) \\  \\ log(\frac{a}{b}) = log(a) - log(b) \\  \\ log(a^n) = n log(a)

Tell whether the lines for each pair of questions are parallel or perpendicular or neither y=5/3x+3. 20x+12y=12
disa [49]

neither

• Parallel lines have equal slopes

• The product of perpendicular slopes = - 1

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = \frac{5}{3} x + 3 is in this form

with slope m = \frac{5}{3}

rearrange 20x + 12y = 12 into this form

subtract 20x from both sides

12y = - 20x + 12 ( divide all terms by 12 )

y = - \frac{5}{3} + 1 ← in slope-intercept form

with slope m = - \frac{5}{3}

Neither of the conditions for parallel/ perpendicular slopes are met

Hence the lines are neither parallel/ perpendicular

Parker ran at 6 miles per hour for 27 minutes and 39 seconds. How far did Parker run?
DedPeter [7]

Answer:

Parker ran 2.76 miles

Step-by-step explanation:

distance = speed x time

First, we have to convert 27 minutes and 39 seconds to minutes only we do this with 39/60 because then the seconds divide by total seconds and we can use it as a decimal

39/60 = .65

So it took 27.65 total minutes now we must convert it to hours, so that the 6 MILES per hour has matching terms, we do this by dividing 27.65 by 60 (theres 60 total minutes in an hour)

So it took 0.460833333 hours at a 6 mph pace, we can round this to 0.46

Now we can plug in the time and speed

Distance = 6mph x 0.46 hours

Distance = 2.76 miles
