<h3>
Answer:</h3>
5.51 seconds
<h3>
Step-by-step explanation:</h3>
y = 0 when the stone hits the ground. At that point, t can be found from ...
... 0 = -16t^2 +486
... 0 = t^2 -30.375 . . . . divide by -16
... 30.375 = t^2 . . . . . . add the opposite of the constant
Take the square root to get ...
... √30.375 = t ≈ 5.51 . . . . seconds
Answer:
$559.77
Step-by-step explanation:
Total cost = 
We need to find 4.5% of 525.61. This will be state tax.
We need to find 2% of 525.61. This will be city tax.
Converting 4.5% to decimal (4.5 divided by 100) and then multiplying with 525.61 will give us the answer.
State tax = 
City tax = 
Grand total purchase price is 525.61 + 23.65 + 10.51 = $559.77
The equation of a line in slope intercept form is y=mc+b where m is the x-intercept. False. M represents the slope
A force of 4.05×10⁶ N was exerted on one side of the wall.
<h3>What is the force?</h3>
Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.
The following data were obtained from the question:
Breadth (B) = 4 m
Length (L) = 10 m
Standard pressure (P) = 101325 Nm¯²
Next, we shall determine the area of the wall. This can be obtained as follow:
Area (A) = length (L) × breadth (B)
A = 10 × 4
A = 40 m²
Finally, we shall determine the force exerted on one side of the wall as follow:
Standard pressure (P) = 101325 Nm¯²
Area (A) = 40 m²
Pressure (P) = Force (F) /Area (A)
101325 = F/40
F = 101325 × 40
F = 4.05×10⁶ N.
Therefore, a force of 4.05×10⁶ N was exerted on one side of the wall.
