Answer:
The slope intercept form of a line os :y=mx+b where m is the slope and b is the y-intercept.The y-intercept is always where the line intersects the y-axis,and will always appear as (0,b) in co-ordinate form .
It means you have to express y in terms of x.
in other words it means you have to re write the equation so that y is in one side and x and some other numbers should be in the other side.
example- y=2x+4 or
y= 5x+6
The order of selection does not matter. Therefore we need the number of combinations of the 6 hats taken 4 at a time.
It looks to be about y=1.5/6x+6
Answer:
0.53πrad
Explanations:
Given the radius of the circular track = 60metres
If she walks a total of 100 meters, the length of the arc of the circle = 100metres
To calculate the radian angle she rotates about the center of the track, we will use the formula for calculating the length of an arc
L = θ/360° × 2πr
100 = θ/360× 2π(60)
36000 = 120π × θ
36000 = 376.8θ
θ = 36000/376.8
θ = 95.5°
Since 180° = πrad
95.5° = x
x = 95.5π/180
x = 0.53π rad
