45.3541618818 is the answer
A). Pi m
Explanation:
Arc length formula:
Arc length = (Ø/360°) * 2*Pi*r
Ø = given angle (degrees)
r = radius
Plug given numbers in:
(45°/360°)* 2* Pi * 4
This will give you the answer of Pi
Answer:
3 metres
Step-by-step explanation:
If y= distance (in meters) from the finish line
x= time in seconds after the beginning of the leg of relay race.
At x=0, when the race has not started,
From the runner's equation
y+4(0)=100
y=100 metres
Also, from his opponent's equation
y+3.8x=97
y+(3.8X0)=97
y=97
The distance needed by the runner to catch up to his opponent
= 100-97 =3 metres
Answer:
M(x,y) = (0,0)
Step-by-step explanation:
The endpoints are (2,2) and (-2,-2)
<u><em>Let's find the midpoint now</em></u>
=> M(x,y) =
=> M(x,y) =
=> M(x,y) =
=> M(x,y) = (0,0)
