a ball is dropped from a height of 20 feet. each time it drops h feet, it rebounds 0.89h feet. find the total distance traveled by the ball. (round your answer to two decimal places.)
a ball is dropped from a height of 20 feet. each time it drops h feet, it rebounds 0.89h feet, 343.63 feet the total distance traveled by the ball.
What is distance?The length of the line connecting any two places is known as their distance from one another. Subtracting the different coordinates will reveal the distance if the two locations are on the same horizontal or vertical line.
h₁ = 20 feet = h
h₂ = 0.89h
h₃ = 0.89²h
h₄ = 0.89³h
...........................
h(n) = 0.89ⁿh
Therefore, total distance travelled = 20 + 2 (0.89h + 0.89²h + 0.89³h +.....)
= 20 + 2h (0.89 + 0.89² + 0.89³ +.....)
Sum of (h.p)∞ = a/ (1-r)
Where, a = first term = 0.89
r = common ratio = 0.89
total distance travelled = 20 + 2 × 20 ×(0.89) × [1/(1 - 0.89)]
= 343.63 ft.

Rewrite x^2+4x−20=−8
in the form (x−p)2=q
Step-by-step explanation:
then we do the multiplications and compare :
(x - p)² = q
x² - 2px + p² = q
x² - 2px + p² - q = 0
our target is
x² + 4x - 20 = -8
x² + 4x - 12 = 0
now we compare the variable expression with the target.
x² = x² check
4x = -2px
4 = -2p
p = -2
-12 = p² - q = 4 - q
-16 = -q
q = 16
so, we have
(x - -2)² = 16
(x + 2)² = 16
what's the GCF of 3a+5a
The common factor, in this case, is a, so the GCF is still a.
What is the greatest common factor (GCF)?
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
To find the greatest common factor (GCF) of two or more terms, we need to factor each term and then identify the factors that are common to both terms.
In this case, we have the terms 3a and 5a. To find the GCF, we can factor each term as follows:
3a = 3a
5a = 5a
The only common factor between the two terms is a, so the GCF of 3a and 5a is a.
Alternatively, we could have written the terms as:
3a = 3 * a
5a = 5 * a
Hence, The common factor, in this case, is a, so the GCF is still a.

What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element. A relation between a domain and range is called a function when each value in the domain only has one value in the range.

A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associate is $400 and the daily rate for each partner is $1000. The law firm assigned a total of 16 lawyers to the case and was able to charge the client $11800 per day for these lawyers' services. Write a system of equations that could be used to determine the number of associates assigned to the case and the number of partners assigned to the case. Define the variables that you use to write the system of equations.
Using system of linear equations, the law firm employed 7 associate and 9 partners
System of Linear EquationThe system of linear equations can be defined as a set of two or more linear equations that have the same variables. Linear equations can be said as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.
In this question, we have to write out two equations and solve for the unknown variable.
let;
x = associatey = partnerx + y = 16 ...eq(i)
400x + 1000y = 11800 ...eq(ii)
From equation 1
x = 16 - y ...eq(iii)
Put eq(iii) into equation (ii)
400(16 - y) + 1000y = 11800
6400 - 400y + 1000y = 11800
6400 + 600y = 11800
600y = 11800 - 6400
600y = 5400
y = 5400 / 600
y = 9

What is angles?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
The sum of the angles in a triangle is :
A° + B° + C° = 180°
Where A, B and C are the three angles in a triangle.
Hence, if two of the angles are given as : 55° and 20°
The measure of the third angle will be :
Let the measure of the third angle = C
(55 + 25 + C) = 180°

Paula is standing on a bridge that is 110 above
the water below. She throws a pebble over
the edge of the bridge, and it hits the top of a
24 foot high bridge guard. The quadratic
equation that models the path of the pebble is:
p(t) = -16t² + 48t + 110
such that t is the time in seconds and p is
the height of the pebble.
What is the maximum height of the
pebble?
A) 2 feet
(B) 146 feet
C110 feet
D) 210 feet
Answer:
(B) 146 feet
Step-by-step explanation:
You want to know the maximum height of a pebble whose height is described by p(t) = -16t² + 48t + 110.
Vertex formWe can write the equation in vertex form as follows:
p(t) = -16(t² -3t) +110
p(t) = -16(t² -3t +2.25) +110 +16(2.25)
p(t) = -16(t -1.5)² +146
This shows the vertex of the quadratic curve to be (1.5, 146).
The maximum height of the pebble is 146 feet.
