Answer:
Central angle = θ = 2.5 radians
Step-by-step explanation:
The radian measure of central angle is given by
Where s is the arc length, r is the radius of circle and θ is angle in radians
We are given an arc length of 5 units
We are given radius of 2 units
Therefore, the central angle in radians is
Bonus:
Radian is a unit which we use to measure angles.
1 Radian is the angle that results in an arc having a length equal to the radius.
Degree is another unit that we use to measure angles.
There are 360° in a circle.
There are 2π radians in a circle.
Answer:
Step-by-step explanation:
An exponetial function is represented by
where a is the vertical stretch or initial rate and b is the factor or base.
Since neither point have a x coordinate of zero. Use this method.
plug in y value into the formula and x value into there as well like this
if you divide the second equation from the first
so our equation now is
know let plug one of the point in to find a
Use 3,16
So our equation is
Answer:
Hannah's line should start at 220 and Brandon's at 340 and should go down each hour by 30 and 50 respectively.
Step-by-step explanation:
substitution:
7x-9= 3x-1
4x= 8
x=2
