Answer:1.2
Step-by-step explanation:
Step-by-step explanation:
Let the height above which the ball is released be H
This problem can be tackled using geometric progression.
The nth term of a Geometric progression is given by the above, where n is the term index, a is the first term and the sum for such a progression up to the Nth term is
To find the total distance travel one has to sum over up to n=3. But there is little subtle point here. For the first bounce ( n=1 ), the ball has only travel H and not 2H. For subsequent bounces ( n=2,3,4,5...... ), the distance travel is 2×(3/4)n×H
a=2H..........r=3/4
However we have to subtract H because up to the first bounce, the ball only travel H instead of 2H
Therefore the total distance travel up to the Nth bounce is
For N=3 one obtains
D=3.625H
We should find the original number, 7 of 1/10. We divide the known number for the numerator, than multiply for denominator.
7 : 1 = 7 * 10 = 70 <- answer
So 7 is 1/10 of 70
We can check our work:
1/10 of 70 = 7?
70 : 10 = 7*1 = 7
Answer:
Equation have Unique solution i.e 
Step-by-step explanation:
Given Equation:
Solving the Equation for 'x'.
Adding '
' both sides:
Adding '42' both sides:
The equation have Unique solution with the value of
↝ Form into 
where a > 0 (Optional)
↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula
↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝
Therefore, the answer for Complex Number System is (5±√7i)/2
