Answer: The correct answer is: quadratic, because the height increases and then decreases
We are given the below data:
Time (seconds) Height (feet)
0 5
1 50
2 70
3 48
4 4
We know that quadratic model is used in situations when the values increase and then decreases.
Looking at the given, we clearly see the height variable first increase and then goes on decreasing as the time in seconds increases. Therefore, the appropriate model would be quadratic model here and the correct option is:
quadratic, because the height increases and then decreases
Answer:
4x(4x^3+6x^2-2x+3)
Step-by-step explanation:
Answer:
x = 4.98
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 50 = x/6.5
6.5 sin 50 =x
x=4.97928
x = 4.98
Answer:
- C. 15.5 pounds
- D. 8.0 pounds
Step-by-step explanation:
Anything expressed to a precision smaller than 10 pounds will be more precise. Choices C and D are both expressed to a precision of 1/10 pound, so are more precise than a weight expressed to the nearest 10 pounds.
_____
The convention for indicating that the 0 in 10 is significant is to write the number with a trailing decimal point: 10. pounds. Since the number here is not written that way, we must presume its precision is 10 pounds (not 1 pound). Both of the choices 50 and 30 suffer the same problem.
