What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;
The height of a ball in feet is modeled by the equation,
y = - 16x² + 72x
where, x is the time in seconds after the ball is hit.
Hence, For time of the ball in the air, we can plug y = 0 in above equation.
y = - 16x² + 72x
0 = - 16x² + 72x
Solve for x;
- 16x² + 72x = 0
- 4x (4x - 18) = 0
This gives,
4x = 18
x = 18/4
x = 4.5 seconds
Thus, The value of time of the ball in the air is,
⇒ 4.5 seconds

Step-by-step explanation:
as the x values increase, the y values tend to decrease
For the Scatter plot negative the x-values increase, the y-values tend to decrease.
What is Scatterplot?A linear function is a function that, when plotted, creates a straight line. Typically, it is a polynomial function with a maximum degree of 1 or 0. Nevertheless, calculus and linear algebra are also used to represent linear functions. The function notation is the only distinction. It is also important to understand an ordered pair expressed in function notation. When an is an independent variable on which the function depends, the expression f(a) is referred to as a function.
Given
A scatterplot has a negative, linear correlation.
Which is negative correlation means that with the increase/decrease in one variable the other variable also decrease/increase,

Kimela’s little sister likes to swing the playground. Yesterday, Kimela pulled the swing back and let it go. The swing traveled a distance of 9 feet before heading back the other way. Each swing afterward was only 70% as long as the previous one. Find the total distance the swing traveled.
Answers
To find the total distance traveled by the swing, we use the sum of an infinite geometric series formula with the first swing distance being 9 feet and a common ratio of 0.7. The sum equals 30 feet, indicating the total distance the swing traveled.
The question involves finding the total distance traveled by a swing that starts with an initial swing length and then decreases by a certain percentage with each subsequent swing. It can be classified as a series problem in mathematics, specifically dealing with a geometric series.
First swing distance is 9 feet. Each subsequent swing is only 70% of the previous, which means the ratio is 0.7. We want to find the sum of this geometric series. The total distance traveled by the swing is the sum of the distances traveled in each direction, so the swing's distances form an infinite series. To find the total distance traveled, we use the formula for the sum of an infinite geometric series:
S = [tex]\frac{a}{1-r}[/tex]
where S is the sum of the series, a is the first term, and r is the common ratio (in this case, 0.7). Plugging in the values, we get:
S = [tex]\frac{9 feet }{(1 - 0.7)}[/tex] = 9 feet ÷ 0.3 = 30 feet
Hence, the total distance traveled by the swing is 30 feet.
Question 5 Unsaved
What is the equation for the sum of four consecutive numbers totaling 86.
Question 5 options:
4n=86
n+4=86
n+n+1+n+2+n+3=86
n+n+2+n++4+n+6=86
Answers
"The correct equation representing the sum of four consecutive numbers totaling 86 is [tex]\( n + (n+1) + (n+2) + (n+3) = 86 \).[/tex]
To solve this problem, let's denote the first of the four consecutive numbers as n
The sum of these four consecutive numbers is given by the equation:
[tex]\[ n + (n+1) + (n+2) + (n+3) = 86 \][/tex]
Now, let's simplify this equation by combining like terms:
[tex]\[ 4n + 1 + 2 + 3 = 86 \][/tex]
[tex]\[ 4n + 6 = 86 \][/tex]
Subtract 6 from both sides to isolate the term with n
[tex]\[ 4n = 86 - 6 \][/tex]
[tex]\[ 4n = 80 \][/tex]
Now, divide both sides by 4 to solve for n
[tex]\[ n = \frac{80}{4} \][/tex]
[tex]\[ n = 20 \][/tex]
So, the first number in the sequence is 20.
The four consecutive numbers are 20, 21, 22, and 23, and their sum is indeed 86.

B. 1.12*10'4cm should be the correct answer.
The height of the tree which is 11,200 centimeters is written as 1.12*10'4cm in scientific notation. The conversion involves placing the decimal point after the first digit and then counting the number of places moved, which forms the power of 10.
Explanation:The question is asking you to express the height of a tree, which is 11,200 centimeters, in scientific notation. Scientific notation is a way of writing very large or very small numbers into a format that is easier to read and understand. It is formatted as a number between 1 and 10 multiplied by 10 raised to a certain power.
To convert 11,200 into scientific notation, we first place the decimal point after the first digit, which results in 1.12. Secondly, we count the number of places moved. In this case, we moved the decimal point 4 places to the left. Therefore, 11,200 cm is equal to 1.12 × 10^4 cm. So, the correct answer is B. 1.12*10'4cm.

Answers
A) No; 9.3 or 20.6.
B) Yes, because the triangles are similar.
C) No, because the triangles will not necessarily be similar.
There is not enough information to answer Questions 2 or 3.
Explanation for Question 1:
A) We are not told which side is the longest, so these two sides could be placed anywhere in the Pythagorean theorem. They could either be both legs, or one could be the hypotenuse:
Hypotenuse: 13² + b² = 16²
169 + b² = 256
169 + b² - 169 = 256 - 169
b² = 87
b = √87 = 9.3
Both legs: 13² + 16² = c²
169 + 256 = c²
425 = c²
√425 = c
20.6 = c
B) The two triangles will be similar, since each pair of corresponding sides will have the same ratio (2, since it is doubled). Similar triangles have the same angle measures, so this must also be a right triangle.
C) Simply adding a value to each side will not preserve similarity. For example, if we had a triangle with sides 3, 4, and 5, adding 2 to each side would give us 5, 6 and 11. These do not have the same ratios; 3/5 is not the same as 4/6 or 5/11.
Two lines, C and D, are represented by the equations given below: Line C: y = x + 14 Line D: y = 3x + 2 Which of the following shows the solution to the system of equations and explains why?
Answers
Answer:
(6, 20), because both lines pass through this point
Step-by-step explanation:
We see that both equations are equal to y. This means we can set the two equations equal to each other:
x+14 = 3x+2
Subtract x from each side:
x+14-x = 3x+2-x
14 = 2x+2
Subtract 2 from each side:
14-2 = 2x+2-2
12 = 2x
Divide both sides by 2:
12/2 = 2x/2
6 = x
Substitute this into the first equation:
y = x+14
y = 6+14
y = 20
This makes the solution (6, 20).
The solution for the given system of equations are (6, 20).
What is a linear system of equations?A system of linear equations is a set of two or more equations involving two or more variables. All of the equations must be considered at once in order to find the solution, which is any pair of values that makes each equation true independently.

From equation (i) and (ii), we get

x=6
Substitute x=6 equation (i), we get
