Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Graph images undergo transformations, one of the types of transformations are rotations.
rotation is done when each point of the image rotates 90° around a point in the counterclockwise manner.
when rotation is done, (x,y) -> (-y,x)
therefore when taking points from image to original then the reverse is done ;
(-y,x) --> (x,y)
the coordinates of image point q' is (-3,4)
before rotation then the coordinates are (4,3)
answer is (4,3)

Answer:
Step-by-step explanation:
The room is rectangular in shape. The formula for determining the area of a rectangle is expressed as
Area = length × width
The rectangular hotel room is 3 meters by 5 meters. The area of the room would be
Area = 3 × 5 = 15 square meters
The owner of the hotel wants to re carpet the room with carpet that cost $15.00 per square meter. This means that the cost to re carpet the room would be
15 × 15 = $225
