Step-by-step explanation:
A basketball player stands near the middle of the court and throws the ball toward the basket.
The path of the ball is a parabola. The ball leaves the player's hands at a height of 6 feet above the ground. The
ball travels to a maximum height of 12 feet when it is a horizontal distance of 18 feet from the player's hands.
Write a function to represent the height of the ball in terms of its distance from the player's hands?
Answer:
A function to represent the height of the ball in terms of its distance from the player's hands is [tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
Step-by-step explanation:
General equation of parabola in vertex form [tex]y= a(x-h)^2+k[/tex]
y represents the height
x represents horizontal distance
(h,k) is the coordinates of vertex of parabola
We are given that The ball travels to a maximum height of 12 feet when it is a horizontal distance of 18 feet from the player's hands.
So,(h,k)=(18,12)
Substitute the value in equation
[tex]y=a(x-18)^2+12[/tex] ---1
The ball leaves the player's hands at a height of 6 feet above the ground and the distance at this time is 0
So, y = 6
So,[tex]6=a(0-18)^2+12[/tex]
6=324a+12
-6=324a
[tex]\frac{-6}{324}=a[/tex]
[tex]\frac{-1}{54}=a[/tex]
Substitute the value in 1
So,[tex]y=\frac{-1}{54}(x-18)^2+12[/tex]
Hence a function to represent the height of the ball in terms of its distance from the player's hands is [tex]y=\frac{-1}{54}(x-18)^2+12[/tex]

How do I write the equation to get the answer ?
Answer:
which type of equation just tell we are here to help if we can
Answer: Take the information given in the situation. Consider the relationships between the amounts, numbers and unknowns that are in the description.
If the word "is" or "are" is included in the description, that is equivalent to an equal sign.
Words like "and," "also" "more than" and "combined" are clues that there may be addition. "Total" often means the sum of an addition equation.
"From" and "difference" are clues that there is subtraction.
"Times" "by" and "of" art clues for multiplication. "Find the Area of. . ." dedinitely requires multiplication.
"Ratio," 'into' "per" and "among" are clues to division.
Use a letter x, y, d, t, or whatever helps identify the
Step-by-step explanation: Without a specific situation, it is impossible to give a specific answer.
Examples: The total number of seats in the auditorium is 125. 75 tickets have been sold already. How many more tickets are left. (This is the unknown)
The Total is the given 75 plus the unknown.
125 = 75 + x is the equation to start with
What is three-fourths of twelve? "What" is the unknown.
x = 3/4 × 12 is the equation to start with.
The ratio of red marbles to blue marbles is 2:3 There are 25 marbles all together. How many red marbles and how many blue marbles.
In this question there are two equations
2r + 3b = 25 This is the equation for the total r = 2b/3 is the division
Substitute the value of "r" from the second equation to solve the first equation

What plus 32 equals 98
Answer:
66
Step-by-step explanation:
Answer:
Lets numeralise the question,
According to question 32+ ? = 98
So if we take the unknown value as x then we will get,
32+x=98
So by transposing we get,
x=98-32

The graph that best represents an increasing function is (a) A graph shows a non linear curve that joins the ordered pairs (0, 0), and (2.5, 1), and (4, 3).
How to determine the graph that represents an increasing functionFor a graph to represent an increasing function, then as the input values increases, the output values must also increase
This means that:
As the x values increases, the y values must also increase
Hence, the graph that best represents an increasing function is (a)
This is so because as x increases from 0 through 2.5 to 4, y increases from 0 through 1 to 3

The IQ of 10 adults is measured, and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121. Find the range of the data set. (4 points)
A: 83−121
B: 38
C: 96.5
D: 204
Answer:
B
Step-by-step explanation:
range = biggest - smallest
121 - 83 = 38
range = 38
the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.
To find the range of the data set, we need to determine the difference between the highest and lowest values in the set. Given the IQ scores of the 10 adults as 83, 87, 90, 92, 93, 100, 104, 111, 115, and 121, the highest value is 121, and the lowest value is 83.
Thus, the range can be calculated as 121 - 83, which equals 38. Therefore, the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.

There is a negative 1 between the two parenthesis
-1(5x-4)
-5x+4
Now plug it back into the equation and take out the parenthesis
7x+6-5x+4= 180
2x+10=180 Now we can solve

Step-by-step explanation:
First, we need to list out the common multiples of 4 nd 6, less than 30
[tex]4 = 0.4,8,12,16,20,24,28[/tex]
[tex]6 = 0.6,12,18,24[/tex]
Then, we list out the common multiples
[tex]Common\ Multiple = 12,24[/tex]
Since, only 12 and 24 fall in this category.

in 154 N38 what digit should be replaced to N to make the number divisible by 3,6 and 9?
Answer:
[tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.
Step-by-step explanation:
In Number Theory there is a rule of thumb which states that sum of digits of a multiple of 3 equal 3 or a multiple of three. If we know that [tex]n = 154N38[/tex], then its sum of digits is:
[tex]x = 1 + 5+4+N+3+8[/tex]
[tex]x = 21+N[/tex] (Eq. 1)
We have to determine which digits corresponds to multiples of three, there are four digits:
N = 0
[tex]x = 21+0[/tex]
[tex]x = 21[/tex] ([tex]3\times 7 = 21[/tex])
N = 3
[tex]x = 21+3[/tex]
[tex]x = 24[/tex] ([tex]3\times 8 = 24[/tex])
N = 6
[tex]x = 21+6[/tex]
[tex]x = 27[/tex] ([tex]3\times 9 = 27[/tex])
N = 9
[tex]x = 21+9[/tex]
[tex]x = 30[/tex] ([tex]3\times 10 = 30[/tex])
We get the following four distinct options: 154038, 154338, 154638, 154938. Now we find which number is divisible by 6 and 9 by factor decomposition:
[tex]154038 = 2\times 3\times 25673[/tex]
[tex]154338 =2\times 3\times 29 \times 887[/tex]
[tex]154638 = 2\times 3\times 3\times 11\times 11\times 71[/tex]
[tex]154938 = 2\times 3\times 7\times 7\times 17\times 31[/tex]
It is quite evident that [tex]N = 6[/tex] so that number becomes divisible by 3, 6 and 9.
