Determine the 4th point
The coordinate point of a horizontal or a vertical rectangle is given as:
(x1,y1), (x2,y2), (x3,y3), (x4,y4)
Where:
So, we have:
---
----
----
Using the above equations:
Hence, the coordinate of the 4th point is:
Answer: the radius is 2.61 cm
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Volume = 156 cm³
Height = 7.3 cm
Therefore,
156 = 3.14 × r² × 7.3
156 = 22.922r²
r² = 156/22.922 = 6.81
Taking square root of both sides of the equation, it becomes
r = 2.61 cm
Answer: Option D
Step-by-step explanation:
Note that the projectile height as a function of time is given by the quadratic equation
To find the maximum height of the projectile we must find the maximum value of the quadratic function.
By definition the maximum value of a quadratic equation of the form
is located on the vertex of the parabola:
Where
In this case the equation is:
Then
So:
