<u>Answer:</u>
x = 4 (extraneous solution)
<u>Step-by-step explanation:</u>
This solution is extraneous. Reason being that even if it can be solved algebraically, it is still not a valid solution because if we substitute back , we will get two fractions with zero denominator which would be undefined.
Answer:
Step-by-step explanation:
The calculation of the value of p minimizes is shown below:-
We will assume the probability of coming heads be p
p(H) = p
p(T) = 1 - P
Now, H and T are only outcomes of flipping a coin
So,
P(TTH) = (1 - P) = (1 - P) (1 - P) P
= (1 + P^2 - 2 P) P
= P^3 - 2P^2 + P
In order to less N,TTH
we need to increase P(TTH)
The equation will be
3P^2 - 4P + 1 = 0
(3P - 1) (P - 1) = 0
P = 1 and 1 ÷ 3
For P(TTH) to be maximum
= 6P - 4
and
(6P - 4) is negative which is for
He will reach the ground after 2.023 seconds.
To start, write a quadratic equation in vertex form with the given information about the vertex.
All that we need to solve for is a. Plug in the point (0, 9) and you will be able to solve for a and write the complete equation.
Now, just use the quadratic formula and you will get 2.023 seconds for when he hits the ground.
