The ball will return to the ground after approximately 4.5 seconds.
To find the time it takes for the ball to return to the ground, we need to determine when the height of the ball is zero. In other words, we need to solve the equation f(t) = 54t - 12t² = 0.
Let's set the equation equal to zero and solve for t:
54t - 12t² = 0
Factoring out common terms:
t(54 - 12t) = 0
Now, we have two possible solutions for t:
t = 0
This solution represents the initial time when the ball was thrown.
54 - 12t = 0
Solving this equation for t:
54 - 12t = 0
12t = 54
t = 54 / 12
t = 4.5
So, the ball will return to the ground after approximately 4.5 seconds.

Find the equation of the line passing through the given point and perpendicular to the given line
Answer:
5x + y = 34
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x - 5y = 8 ( subtract x from both sides )
- 5y = - x + 8 ( divide through by - 5 )
y = [tex]\frac{1}{5}[/tex] x - [tex]\frac{8}{5}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{1}{5}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{5} }[/tex] = - 5 , then
y = - 5x + c ← is the partial equation
to find c substitute (5, 9 ) into the partial equation
9 = - 25 + c ⇒ c = 9 + 25 = 34
y = - 5x + 34 ← equation of perpendicular line in slope- intercept form
add 5x to both sides
5x + y = 34 ← equation in standard form
How do you find the perpendicular bisector of a line segment?
The perpendicular bisector can be found by solving for the equation of the line and substituting the two points.
The perpendicular bisector of a line segment can be found by using the midpoint formula. The midpoint formula is used to find the midpoint of two points (x1,y1) and (x2,y2). The formula is:
Midpoint = (x1 + x2)/2, (y1 + y2)/2
Once the midpoint is found, the slope of the perpendicular line is found by using the negative reciprocal of the original line. The formula for the slope of the perpendicular line is y = -1/m * x + b, where m is the slope of the original line.
The equation of the perpendicular bisector is then found by substituting the slope and the midpoint into the equation of a line, y - y1 = m(x - x1).
Finally, the perpendicular bisector can be found by solving for the equation of the line and substituting the two points. The resulting equation is the equation of the perpendicular bisector.

A lighthouse sits at the edge of a cliff, as shown. A ship at sea level is meters from the base of the cliff. The angle of elevation from sea level to the base of the lighthouse is . The angle of elevation from sea level to the top of the lighthouse is . Find the height of the lighthouse from the top of the cliff. Do not round any intermediate computations. Round your answer to the nearest tenth. Note that the figure below is not drawn to scale.
There is no numbers provided, but this is how you solve it.
We can use the tangent function to solve for the height of the lighthouse.
Let h be the height of the lighthouse from the top of the cliff.
tan(angle of elevation from sea level to the top of the lighthouse) = (h+ height of lighthouse from sea level ) / distance from the base of the cliff
tan( angle of elevation from sea level to the top of the lighthouse) = (h+x) / distance from the base of the cliff
tan(angle of elevation from sea level to the base of the lighthouse) = (h) / distance from the base of the cliff
By dividing the first equation by the second equation
(h+x) / distance from the base of the cliff = tan( angle of elevation from sea level to the top of the lighthouse) / tan( angle of elevation from sea level to the base of the lighthouse)
(h+x) = (h) * (tan( angle of elevation from sea level to the top of the lighthouse) / tan( angle of elevation from sea level to the base of the lighthouse))
h = (x * tan( angle of elevation from sea level to the base of the lighthouse)) / ( tan( angle of elevation from sea level to the top of the lighthouse) - tan( angle of elevation from sea level to the base of the lighthouse))
After plugging in the values into the equation, we get:
h = (x * tan( )) / ( tan( ) - tan( ))
Round to the nearest tenth
h = (x * tan( )) /

What is circle ?
A circle is a two-dimensional geometric shape defined as the set of all points that are a fixed distance, called the radius, from a central point, called the center. A circle is the set of all points in a plane that are at a given distance from a given point, the center.
The area of a circle is given by the formula A = [tex]\pi r^{2}[/tex], where r is the radius of the circle. To find the area of a circle with a diameter of 5 m, we first need to find the radius. We can do this by dividing the diameter by 2:
r = 5 m / 2 = 2.5 m

What is the factor theorem formula?
The Factor Theorem states that if a polynomial P(x) has a factor (x-a), then P(a) = 0. In other words, if x-a is a factor of the polynomial, then the value of the polynomial when x=a is equal to zero.
The factor theorem is a fundamental concept in algebra and polynomial functions. This can be useful for determining the roots of a polynomial equation.
Key points:
The factor theorem only applies to polynomials, not other types of functions.The factor (x-a) must be a factor of the polynomial, not just a term.The value of P(a) will be zero only if x-a is a factor of the polynomial, not if it is just a root.The factor theorem can be used to find the roots of a polynomial equation by setting P(x) = 0 and solving for x.The factor theorem is closely related to the remainder theorem, which states that if P(x) is divided by (x-a), the remainder is P(a).In summary, The Factor Theorem is a fundamental concept in Algebra and Polynomials, it helps us understand the relationship between the roots and the factors of a polynomial equation and how a root of a polynomial is related to the value of the polynomial evaluated at that point.
