Answer:
A , B and E.
Step-by-step explanation:
the scientist can control and deal with the measure of manure that is given to a solitary corn plants. thus A is correct.
The reaction variable is the yield recorded for each plot due to the fact that the yield recorded in each plot is needed to check whether the compost is given or not. choice B is also correct
it's considered an experiment because the specialist is controlling the autonomous variable. then E is a right choice.
It is given in the question that
And the given expression is
Substituting the values of a,b and c, we will get
So with the given values of a,b and c, we will get
It has two solutions because there is two Xs in the equation (x-4) (x-4)=36 which will get u two answers
Answer:
12i
Step-by-step explanation:
Step 1: Write it out
√-144
Step 2: Factor
√144(√-1)
Step 3: Evaluate
12i
200 km....... 3,5 h
100 km........1,5 h
v1= 200/3,5=57,1
v2= 100/1,5= 66,6
vm=( 57.1+66,6)/2≈ 61,5 km/h
