Answer: 11.25 secs
Step-by-step explanation:
So in this sense the rockets origin or the ground is modeled at h=0 so the time required if used on a table shows that h=0 between the values of 11 and 12. So if you plug and chug decimal values between these two values you get exactly 0 at t=11.25 so it takes approximately 11.25 seconds for the rocket to return to the ground
Answer:
C
Step-by-step explanation:
The graph can take any value of X
-3[ x^2 - 2x + 1] + 4
-3x^2 +6x -3 + 4
-3x^2 + 6x + 1
x can take any value of real numbers and there would be a solution
Hence all real numbers is the domain.
The answer to those options is of course C
A. 56 cards
B. 120 cards
Sorry if it's wrong, I'm kind of confused. :P
Answer:
Option D, i.e., -0.7.
Step-by-step explanation:
Correlation describes the relation between two variables. It is defined by r and the value of correlation lies in the interval [-1,1].
If r=1, it represents strong positive correlation between two variables.
If r=0, it represents no correlation between two variables.
If r=-1, it represents strong negative correlation between two variables.
It is given that the value of a car decreases with age. The value of one variable decreases if the value of another variable increases. It means, the given problem has negative correlation.
If the data points lie about a straight negative line then coefficient is -1.
Since, the data set is not given, so the it represents moderate negative correlation, i.e, r=-0.7.
Therefore, the correct option is D.
