Step-by-step explanation:
Answer: If a superball is dropped from a height of h feet and left to bounce forever, the total time needed for all this bouncing to take place can be represented by the formula:
t = h / (r - 1)
where t is the total time, h is the height from which the ball is dropped, and r is the rebound ratio of the ball.
The rebound ratio of the ball is the fraction of the ball's initial height that it bounces back up after each bounce. For example, if a ball has a rebound ratio of 0.5, it will bounce back up to half its initial height after each bounce.
The total time needed for the ball to bounce forever is equal to the height from which the ball is dropped divided by the difference between the rebound ratio and 1. This is because the ball will bounce back up a fraction of its initial height after each bounce, and the total time needed for all the bounces to take place is determined by the difference between the height of the ball and the fraction of the height that it bounces back up.

What is a 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. Each function has a range, codomain, and domain.
f(x)=60x+80 is function that represents the charge to Ginny's customers, where x represents the number of hours of labor.
To find initial fee, put x = 0 in the given function.
Put x = 0 in f(x) = 60x + 80:
f(0) = (60×0) + 80
f(0) = 80
The initial fee is $80.
From the table,
When x = 0, cost = $ 60.
The initial fee is $60.

How much would you need to deposit in an account now in order to have $4000 in the account in 15 years? Assume the account earns 2% interest compounded monthly.
2,985/- need to deposit in an account.
To calculate the interest we use one type of formula which is
A=P(1+r/n)^(t n)------------------(1)
In the above formula:
A = Accrued amount.
P = Principal amount.
r = Annual nominal interest rate as a decimal.
n = number of compounding periods per unit of time.
t = time in decimal years.
I = Interest amount.
ln = natural logarithm.
Given That
A=4000 t=15 r=2% n=2
changing the r in % into decimal we get 0.02.
Now we substitute the values in the above Formula, and we get
A=P(1+r/n)^(t n)
4000=P(1+.02/2)^(15*2)
4000=P(1.01)^(30)
4000=P(1.34)

The top and bottom margins of a poster are 4 cm and the side margins are each 4 cm. If the area of printed material on the poster is fixed at 390 square centimeters, find the dimensions of the poster with the smallest area.
The dimensions of the poster with the smallest area are; 27.75 cm x 27.75 cm
How to solve algebra word problems?Let "x" and "y" denote the length and the width of the poster.
We are told that the margin of a poster are 4 cm and the side margins are 4 cm.
The length of the print = x - 2(4) = x - 8
The width of the print = y - 2(4) = y - 8
The area of the print = length * width = (x - 8)(y - 8)
The area of the print is given as 390 square inches. Thus;
(x - 8)(y - 8) = 390
Making y the subject gives;
y = (390/(x - 8)) + 8
The area of the poster is; A = xy
Thus;
A = x[(390/(x - 8)) + 8]
A = (390x/(x - 8)) + 8x
Minimizing the area gives;
A' = 8 - (3120/(x - 8)²)
Equating to zero gives;
8 - (3120/(x - 8)²) = 0
8(x - 8)² = 3120
(x - 8)² = 3120/8
(x - 8)² = 390
x = 27.75 cm
y = (390/(27.75 - 8)) + 8
y = 27.75 cm

Positive: between 0 seconds and 5 seconds
Negative: for time greater than 5 seconds (represents time after
the ball hits the ground)
Increasing: for time less than 2 seconds
Decreasing: for time greater than 2 seconds
Relative Maximum: at 2 seconds, when the height of the football is 9 feet
Height of Football (ft)
End Behavior: As time increases, the height of the football decreases.
Symmetry: The height of the football for time between 0 seconds and 2 seconds
is the same as the height for time between 2 seconds and 4 seconds.
The quadratic function that models the path of the ball is given as follows:
y = -(x - 2)² + 9.
The graph of this quadratic function is given by the image shown at the end of the answer.
How to define the path of ball?The ball is increasing, and then later it decreases, meaning that it is defined by a concave down quadratic function.
The ball has a positive height until 5 seconds, hence one of the roots of the quadratic function is of 5, that is, when x = 5, y = 0.
The vertex of the quadratic function is given as follows:
(2,9).
Hence the vertex form definition of the quadratic function is given as follows:
y = a(x - 2)² + 9.
When x = 5, y = 0, hence the leading coefficient a is obtained as follows:
0 = a(5 - 2)² + 9
9a = -9
a = -1.
Hence the quadratic function is given as follows:

For an average intake of 2200 calories per day, the number of acres of land owned is 2.03
How to determine the number of acres?From the question, we have the following calories function that can be used in our computation:
C(x) = 270 ln(x + 1) + 1900
Also from the question, we have
Average intake of calories = 2200 inches
This means that
C(x) = 2200
So, we have the following equation
270 ln(x + 1) + 1900 = 2200
Subtract 1900 from both sides
270 ln(x + 1) = 300
Divide 270 from both sides
ln(x + 1) = 1.11
Take the exponent of both sides
x + 1 = 3.03
So, we have
x = 2.03
Hence, the number of acres is 2.03

What are the vertex and range of y = |4x + 8| − 1?
The vertex and range of y = |4x + 8| - 1 will be (-2, -1) ; -1 ≤ y < ∞ respectively. Using the concept of function -
What is function?According to the function, every value in the domain is associated to exactly one value in the range, and they have a predetermined domain and range. This specific sort of connection is what it is called.
Given that,
y = |4x +8| - 1
To get the vertex of y = |4x +8| - 1 as follows.
Where the absolute values are zeros are the vertex points of the absolute value function.
or, |4x +8| = 0
or, 4x +8= 0
or, 4x = -8
or, x = -2
Substitute the value into an original function,
y = |4(-2) + 8| - 1
y= 0 - 1
y = - 1
As a result, the vertex is at (-2, -1)
Remember that the domain is specified in the range of (-∞, ∞) while determining the range.
Given that |4x + 8| ≥ 0 , (absolute value is always 0 or positive)
The result of adding -1 to the inequality's two sides is
|4x + 8| - 1 ≥ - 1
But since |4x + 8| - 1 is identical to f(x) = y, we have y = f(x) - 1, which means that the range is specified for all values larger than -1.
So the range is -1 ≤ y < ∞
Thus,the vertex and range of y = |4x + 8| - 1 will be (-2, -1) ; -1 ≤ y < ∞ respectively.

Where y is the "independent" variable and 0 to k are the "regression" coefficients. In a "multiple linear regression" model, the "independent" variables are x1, x2, x3,..., xk, and the "residual" or "error" term is.
The "residual" for the regression model is calculated using the following formula.
Residual=y-ŷ
Where y is the "independent variable's" "actual" value and is the "independent variable's" "predicted" value.
The "difference" between the "actual" value of the "dependent" variables and the corresponding "predicted" value when employing the "multiple regression" model is referred to as the "residual" in the "residual" formula.
A statistical technique for evaluating the relevance of a "multiple regression" model is the "F test." Linear models are A linear model is a statistic that explains the “relationship” between “response” and “predictor” variables. Using the “multiple regression” model, the “predicted” value of the “response” variable is denoted by ŷ.
hence option 4 is correct

1.A statistic that is used to evaluate the significance of the multiple regression model
2.A statistic that explains the relationship between response and predictor variables
3.The predicted value of the response variable using the multiple regression model
4.The difference between the actual value of the response variable and the corresponding predicted value (regression error) using the multiple regression model
In an analysis of variance with a between-groups population variance estimate of 30 and a within-groups estimate of 25, the F ratio is A) 25 / (30–25) = 5.00
B) (30–25) / 30 = 0.17 C) 25 / 30 = 0.83
D) 30 / 25 = 1.20
The F ratio is 1.2.
What is statistic?
The study of statistics focuses on gathering, organizing, organizing, analyzing, interpreting, and presenting data. It is customary to start with a statistical population or a statistical model to be researched when applying statistics to a scientific, industrial, or social problem.
30/25 = 1.2
In an ANOVA, this statistic is used in the F test to test the hypothesis that the group means are not equal to one another. The F ratio is calculated as follows:
Fobs=MSB/MSW
30/25 = 1.2
Where MSB is the mean square between the groups and MSW is the mean square within the groups.

5x +6 (x-2) -8 (x-3) please help
Answer:
3x + 12
Step-by-step explanation:
5x + 6(x - 2) - 8(x - 3) ← distribute parenthesis
= 5x + 6x - 12 - 8x + 24 ← collect like terms
==(5x + 6x - 8x) + (- 12 + 24)
= 3x + 12
