Answer:
It took the cell phone 4.15 seconds to reach the ground
Step-by-step explanation:
The formula is , where t is the time and h is the height
The height of that the cell phone dropped from it is 275 feet above the ground
∴ h = 275
- Substitute the value of h in the formula to find t
∵
∴
- Change it to decimal
∴ t = 4.15 seconds to the nearest 2 decimal places
It took the cell phone 4.15 seconds to reach the ground
Answer:
Step-by-step explanation:
Let's start by finding the first derivative of . We can do so by using the power rule for derivatives.
The power rule states that:
This means that if you are taking the derivative of a function with powers, you can bring the power down and multiply it with the coefficient, then reduce the power by 1.
Another rule that we need to note is that the derivative of a constant is 0.
Let's apply the power rule to the function f(x).
Bring the exponent down and multiply it with the coefficient. Then, reduce the power by 1.
Simplify the equation.
Now, this is only the first derivative of the function f(x). Let's find the second derivative by applying the power rule once again, but this time to the first derivative, f'(x).
Simplify the equation.
Therefore, this is the 2nd derivative of the function f(x).
We can say that:
Answer:8
Step-by-step explanation:
If you would like to know how much is the stock worth now, you can calculate this using the following steps:
1 year: 6 1/2 % of $875 = 6.5% * $875 = 6.5/100 * 875 = $56.875
$875 + $56.875 = $931.875
2 year: 6 1/2 % of $931.875 = 6.5% * $931.875 = 6.5/100 * 931.875 = $60.572
$931.875 + $60.572 = $992.447
3 year: 6 1/2 % of $992.447 = 6.5% * $992.447 = 6.5/100 * 992.447 = $64.509
$992.447 + $64.509 = $1056.956 = $1056.96 = $1057
The correct result would be: The stock is worth $1057 now.
