Look at the lines half way between the numbers.
The closest one to the tip of each implement is what it's rounded to.
Answer:
b and c, b and c are same
Step-by-step explanation:
Only a and d can be evaluated using simple substitution.
For a, integral of the square root of (x-1)dx i.e
let y = x-1
dy = dx
It becomes integral square root of ydy, ∫√ydy
which is can easily be evaluated and y is substituted back.
For d, integral of x times the square root of the quantity x squared minus 1
let y= x squared minus 1
then dy = 2xdx
dx = dy/2x
It becomes integral x times square root of y dy/2x
∫x√ydy/2x=∫√ydy/2=1/2∫√ydy which can easily be evaluated and y is substituted back
the answer's 85

Answer:
0 to -180 is the same rotation as -180 to -360
Step-by-step explanation:
0 to -180 is clockwise direction. since the rotation is of a total of 180 degrees, which means that from any angle, it has to rotate an extra 180 degree clockwise. Furthermore, another answer could be from 180 to 0, or 90 to -90, etc.
