The lower square root would be 4.2
Answer:
-12
Step-by-step explanation:
Here the coefficients a, b and c are 4, 8 and -8 respectively.
-b
A formula for the axis of symmetry is x = -------
2a
-8
... which yields x = --------- = -1
2(4)
Evaluating f(x) = 4x^2 + 8x - 8 at x = -1 yields f(-1) = 4(-1)^2 + 8(-1) - 8 = -12.
The y-value of the vertex is -12. Note that the vertex lies right smack on the axis of symmetry.
Answer:
207
Step-by-step explanation:
1. False. 0 does not equal to 6. No answers.
2. False. x=0 means the answer is 0.
3. True.
4. False. 2 does not equal -2. No answers.
5. True.
Code: (6*6*6)-(3*3)=207
Answer:
3.7777777777 or you could round it to 3.8
Step-by-step explanation:
Answer: The probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
Step-by-step explanation:
Since we have given that
Probability of making his shot = 80%
Probability of missing his shot = 20%
We need to find the probability that his friend doesn't make a shot until his 5th attempt.
So, our required probability would be

Hence, the probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
