Answer:
7 radians
Step-by-step explanation:
In a circle, an angle measuring 2π radians intercepts an arc of length 14π. Find the radius of the circle in simplest form.
Since our Angle in in radians
The formula for Arc length = S = rθ
S = 14π
θ = central angle = 2π radians
Hence
r = S/θ
r = 14π/2π radians
r = 7 radians
Radius = 7 radians
Which of these shows how to plot the point to mark the skating rink?
From the origin, move 1.5 units to the left along the x-axis and 1 unit vertically down, and place the point.
From the origin, move 1 unit to the left along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1 unit to the right along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1.5 units to the right along the x-axis and 1 unit vertically down, and place the point.
Answer:
The correct option is 1.
Step-by-step explanation:
It is given that the skating rink is at (−1.5, −1).
Here, x-coordinate is -1.5 and y-coordinate is -1.
In a point P(a,b),
If a>0, then the point P is a units right from the origin and if a<0, then the point P is a units left from the origin.
If b>0, then the point P is b units up from the origin and if b<0, then the point P is b units down from the origin.
It the given point (-1.5, -1), a=-1.5 and b=-1 both are negative.
From the origin, move 1.5 units to the left along the x-axis and 1 unit vertically down, and place the point.
Therefore the correct option is 1.
