Answer:
(-1,-6)
Step-by-step explanation:
We have the following function:
The following transformation is applied
So
For a second order function in the format:
The vertex is:
In which
In this problem
So
Then
So the correct answer is:
(-1,-6)
Answer:
Step-by-step explanation:
Key features
when t = 0
the initial height is 143/3 = 47⅔ ft
initial velocity is -310/3 = -103⅓ ft/s (downward)
initial acceleration is 2(64) = 128 ft/s² (upward)
I would not like to ride this roller coaster!
that's about four times the acceleration of gravity, and it only increases as the car gets to the bottom of the curve at t = 1 s
For part 3
I'm not sure what they mean by "not realistic"
while the initial acceleration is high. the acceleration at t = 1 is zero except that in 'reality' the car would have to be going through a curve to change direction from down to up. That would create very high centripetal acceleration and therefore centripetal forces.
Answer:
y=1/2x+1
Step-by-step explanation:
First use slope formula.
Plug in the information needed.
The slope is .
Now, use point-slope formula.
y-y1=m(x-x1)
Plug in the information needed.
y-3=1/2(x-4)
y-3=1/2x-2
y=1/2x+1
The equation of the line in slope-intercept form is y=1/2x+1.
Hope this helps!
If not, I am sorry.
Answer:
B. -6
Step-by-step explanation:
The common difference here is the difference between each term. Since it is an arithmetic sequence the difference between each term will be the same value.
So, from 45 (the 1st term) to 39 (the 2nd term), the difference is -6
From 39(the 2nd term) to 33, the difference is also -6.
Therefore, we know that the common difference fro this arithmetic sequence is -6.
Hope this helps and ask me any question if it does not :)
