Answer:
Step-by-step explanation:
1) Slope of the given line = -3
slope of the perpendicular line = 1/3
y - 0 = 1/3(x-9)
y = 1/3x - 3
2) slope of the parallel line = -3
y - 0 = -3(x-9)
y = -3x + 27
<u><em>Answer:</em></u>
It would take him 4.8 hours to walk 6 miles
<u><em>Explanation:</em></u>
<u>1- getting his old speed:</u>
We are given that the man can walk 5 miles in 6 hours
Speed is distance/time
<u>Therefore:</u>
Old speed = 5/6 miles/hour
<u>2- getting his new speed:</u>
We are given that his speed increased by 50%
<u>This means that:</u>
New speed = old speed + (50% * old speed)
New speed = miles/hour
<u>3- getting the time taken to walk 6 miles based on new speed:</u>
Hope this helps :)
The anwser is 1/4 or 25% or .25
Given that the area of a 15° secant has an area of 11.9 m2, then the area of the circle will be given by:
(Total measure in degrees of the circle)/(measure in degrees of the secant)*(area of secant)
=360/15*11.9
=24*11.9
=285.6 m^2
Answer: 285.6 m^2
