Answer:
The provided radical equation has no solution.
x = 225/16 is not a valid solution.
Step-by-step explanation:
The given equation is
Add 3 to both sides of the equation
Squaring both sides
Divide both sides by 16
Check by substituting the value of x back into the original equation to confirm the extraneous solution.
Since -18 is not equal to 12, thus the value of x fails to satisfy the equation.
Consequently, x = 225/16 is an extraneous solution.
Step-by-step explanation:
Solution:
We know, g(x) = f(x) + k --------(1)
It is given that f(x) =
(x+2)
and g(x) =
(x+5)
Substituting f(x) and g(x) into equation (1):
→
(x+5) =
(x+2) + k
→
= k
→ k = 
Thus, the value of k is 1.
Answer:
The formula representing the penny's height as a function of time is:

After 7 seconds, the height of the penny will reach 667 feet.
Step-by-step explanation:
The penny experiences free fall.
With an initial velocity of zero and an initial height of h(0)=1,451.
Gravity acts as the acceleration, measured as g=32 ft/s^2.
The model can be initiated by analyzing speed:

Then, the height is expressed as:

The height of the penny at approximately 7 seconds can be calculated as:

After 7 seconds, the penny will stand at a height of 667 feet.
