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
Answer:
Each section of the board is 1/3 or 0.334(0.333333333333) of a meter
Step-by-step explanation:
3/5 divided by 3 is the equation we have to do.
3/5 divided by 3 is also equal to 3/5 times the reciprocal of 3 or 1/3
3/5 * 1/3
3*1 = 3
5*3 = 15
3/15 which can simplify to 1/3. (divide numerator and denominator by 3.)
Each section of the board is 1/3 or 0.334(0.333333333333) of a meter
Answer is A.
step 1 , 16 was not multiplied by 9
