We will use slope intercept form y=Mx+b
M is slope and b is y intercept
So you need a y intercept.
Where does go thro the y axis? +1
From that point how much should you go down and right until you get to the graph again (this is the slope).
Down 1= -1 and right 2= 2. So slope is -1/2
Now write it in the form
Y=-1/2x + 1 is the answer
Cosx = 0.5445
arccos(x) = 0.5445
x = 0.995
Step-by-step explanation:
use Pythagoras theorem,


Answer: the answer is
Step-by-step explanation:
Answer:
a]2.3 hrs
b]3.6hrs
Step-by-step explanation:
4hrs = 12 miles
x = 7miles
4 x 7=28/12=2.3
4 x 11=44/12=3.6hrs
