Answer: When the Block's speed is at maximum
Step-by-step explanation:
From the formula of find acceleration
acceleration = speed/time
So we can tell that acceleration is directly proportional to speed
So when the speed reaches its maximum, acceleration is also maximum, when the speed starts reducing, acceleration also reduced,
Note: talking to account initial and final speed, if these are both the same, for a specific time, acceleration will become zero, because the change in velocity within that specific time is also zero
It’s the first one because the parabola is open
Answer:
33.31 cm or higher
Step-by-step explanation:
Given that:
Mean = 29.79 cm
Standard deviation, s = 1.76 cm
According to the range rule of thumb, values which are greater than or equal to 2 standard deviations from the mean are significantly high values :
Significantly high values are :
Mean + 2(standard deviation)
29.79 cm + 2(1.76)
29.79 + 3.52
= 33.31cm
A) Business means the process of earning money, so she earned $350 at first time, so her initial value would be: $350
Rate of change = 750 - 350 / 350 * 100
= 400 / 350 * 100
= 40000 / 350
= 114.28
Now, There are 4 years between 2014 & 2010 so it will be:
= 114.28 / 4 = 28.57
In short, Your Answer would be 28.57% per year
B) Equation would be: Y = x + 0.2857x
Where, x = number of year
Hope this helps!
