<u>Answer:</u>
The correct answer option is quadratic, because the height increases and then decreases.
<u>Step-by-step explanation:</u>
We are given the following data in the table which represents the height of an object over time:
Time (s) Height (ft)
0 5
1 50
2 70
3 48
We know that in situation where the values increase and then decreases, a quadratic model is used.
From the values given in the table, we can see that the values of height first increased and then decreased with the increase in time.
Therefore, the model used is quadratic, because the height increases and then decreases.
Answer:
y= 3x
Step-by-step explanation:
The slope is just read. It is 3. It is the value of m in the general equation.
y = mx + b
y = 3x + b
To find b, use (-1,-3)
x = -1
y = -3 Substitute into the general equation
-3 = 3(-1) + b Simplify the right side
-3 = -3 + b Subtract -3 from both sides
b = 0
Answer: y = 3x
Answer:
x=2

Step-by-step explanation:
Which is the closest to 6



or 
So, find the square root of each ( I suggest using a calculator)

Which is closest? Let's see.
6 - 5.83 = 0.17
6.24 - 6 = 0.24
6 - 5.91 = 0.09
6.16 - 6 = 0.16
Find the smallest #
0.09 is the smallest, so 5.91 is the closest. Square the #, we get 
Hope this helps! =D
