Answer:
A person who has height less than 5.2521 m can walk under the rope without hitting his/her head.
Step-by-step explanation:
Radius of earth = R
Length of rope around Earth = Circumference of Earth = 2πR
Now add 33 m to the length of the rope that means to increase the circumference
C = 2πR+33
Now,
C = 2πR'
⇒2πR' = 2πR+33
In order to find the height we need to find difference of the radii
⇒2πR'-2πR = 33
So, a person who has height less than 5.2521 m can walk under the rope without hitting his/her head.
Answer:
Step-by-step explanation:
a). By the rotation of 90° clockwise around the origin image ΔE'F'G' will be in 2nd quadrant while Destiny has plotted in fourth quadrant.
b). Rule to find the coordinates of the image will be,
(x, y) → (y, -x)
E(-5, -1) → E'(-1, 5)
F(-2, -3) → F'(-3, 2)
G(-4, -4) → G'(-4, 4)
c). Now we can plot these points on the graph as shown in the attached picture.
