3(x)-14 3(1)-14
3x-14 3-14
-11
Answer:
B.
Step-by-step explanation:
sin∅ = opposite side over hypotenuse
cos∅ = adjacent side over hypotenuse
To find <em>x</em>, there are multiple ways:
tan72° = 6/x
x = 6/tan72°
cos72° = x/15
15cos72° = x
The formula for point slope is:
y-y1=m(x-x1)
m is your slope: 3; plug in 4 for y1 and 2 for x1
y - 4=3(x-2)
1 hour = 60 mins = 3600 sec
-
6 sec = 1 flash
3600 sec = 3600 ÷ 6 = 600 flashes
-
Answer: 600 flashes
Less for statement 1 and less for statement 2
