Answer:
False.
The vertex is at (-7, 4).
Step-by-step explanation:
f(x) = (x + 7)^2 + 4
The minimum value of (x + 7)^2 = 0 (as it's a perfect square) , so minimum of f(x) is 4 when x = -7.
Answer:
2.41 and 2.50
Step-by-step explanation:
Here, we shall be selecting the correct answer from the option.
a. A is correct
the number we want is between 2.4 and 2.8
2.5 is greater than 2.4 but less than 2.5, this means it meets our criteria
b. 2.41 is also correct
This is because it is greater than 2.4 but less then 2.8
c. wrong
2.4 is same as 2.4, it does not meet the criterion
d. wrong
the value is far lesser than 2.4
Answer:
It will take 100 minutes (an hour and 40 mins)
Step-by-step explanation:
Just add 60 and 40 and you will get 100 mins.
In order to achieve an equilibrium some of momentum should be zero about the axis of rotation.
Suppose, the 10-kilogram child is placed X meters away from the axis of rotation.
Now, according to the question
17x2+10X-20x2=0
X=0.6m
Child should sit 0.6m away from the axis of rotation towards 17 Kg child.
