Answer:
Step-by-step explanation:
1)expand out the bracket
-15y+6=21
2) get the y to one side
6=21+15y
3) solve
15=15y
1=y
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: 400
Step-by-step explanation:
I'm not sure 400
3x/2 units to the right, so b).
It's not c) or d), because the -3x/2 is within the sin, rather than outside like y=sin(x)-3x/2
If it were shifted to the left, the equation would be y=sin(x+3x/2)
