T = 2π√(l/g)
<span>=> T = 2π√[5m/(9.8m/s²)] </span>
<span>=> T ≈ 4,49s </span>
To know if they are proportional check to see if there is a number common to the relationship between the y and x to all the numbers:
10/2=5
15/3=5
20/4=5
25/5=5
There is a relationship of 5 and the 5 is multiplied to the x=boxes.
Yes, because the price is 5 times the number of boxes
Area of circle = pie x r^2
GIVEN: radius=22cm REQUIRED: Area = ?
SOLUTION: pie x 22^2 = 484piecm^2
Answer is OPTION D
<span>instead of showing that the conclusion to be proved is true, you show that all of the alternatives are false. To do this, you must assume the negation of the statement to be proved. Then, deductive reasoning will lead to a contradiction: two statements that cannot both be true.</span>
Plug in -3x-(3)=18
Add three both sides
-3x=21
Divide -3 both sides
x=7
