A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet away from the player. The height $y$y (in feet) of a second hockey puck is modeled by $y=x\left(0.15-0.001x\right)$y=x(0.15−0.001x) , where x$x$x is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answer:
The maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels further
Also the distance of the maximum height of first pluck from the player is less than the distance of the second pluck from the player hence the second pluck travels further
Step-by-step explanation:
From the question we are told that
The maximum height of the first pluck is [tex]h_1 = 3 \ ft[/tex]
The height of the second height is mathematically represented as
[tex]$y=x\left(0.15-0.001x\right)[/tex]
=> [tex]y=0.15x -0.001x^2[/tex]
Generally at maximum height [tex]y' = 0[/tex]
So
[tex]y'=0.15 -0.002 x = 0[/tex]
=> [tex]x = 75 \ ft [/tex]
Here 75 ft is the horizontal distance the second pluck traveled at maximum height
So the maximum height of the second pluck is mathematically represented as
[tex]y=0.15(75) -0.001(75)^2[/tex]
=> [tex]y= 5.625 \ ft [/tex]
So comparing the maximum height of the first and the second pluck we see that the maximum height of the second pluck is greater than that of the first pluck, hence the second pluck travels father

What are the slope and the y-intercept of the line shown in the graph?
A. y-intercept = 2 and slope = -3
B. y-intercept = 2 and slope = 3
C. y-intercept = 3 and slope = 2
D. y-intercept = -3 and slope = 2
Answer:
A
Step-by-step explanation:
The y intercept is where the line crosses the Y (vertical) axis. In this case, it happens at y=2
The slope is the rate of change. For every 1 space it moves on the horizontal axis, it moves 3 vertical spaces. It is going down, so it is -3

larry gets a 5% wage rise. his new wage is £252 per week. what was larrys wage before his wage rise
The raise was 5% which is 0.05 as a decimal.
For his new rate his original rate was multiplied by 1.05 ( original + 5%)
To find original amount, divide new amount by 1.05:
252 / 1.05 = 240
His original pay was £240
You can check by multiplying the original pay by 5% and adding:
240 x 0.05 = 12
240 + 12 = 252

What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
As, slope for printer A= 30-2/2-0
= 30/2 = 15 pages per minute.
So, the rate of Printer A is 15 pages per minute.
Thus,
The rate for Printer B is greater than the rate for Printer A because the rate of 25 pages per minute is greater than the rate of 15 pages per minute for Printer A.

2. Tina uSUally brings her children every Sunday afternoon at the children's park in their barangay. The park is 350m Iong and 200m wide complete with slides and
swings for children to play. If is surounded by a pathway of unifom width for children who loves biking and jogging. Suppose the total area of the park and the pathway is 74,464 m2.
a. How wide is the pathway of the park?
b. If you were Tina, woulad you like your children fo go biking and jogging in that park?
Answer: kindly check explanation
Step-by-step explanation:
Given the following :
Total area of parknand path way = 74,464 m2.
Dimension of park = 350m by 200m
Using the area of rectangle formula:
Area = Length * width
Area of park = 350m * 200m
Area of park = 70,000
Area of path = (74,464 - 70,000) = 4,464m2
Since path has uniform width, then width of the the path is sqrt(4464) = 66.8m
2.) the path of the park seems a bit narrow, hence, I wouldn't love children to bike and jog in such a narrow path

Answer:
m∠YPQ = 159°
Step-by-step explanation:
m∠QRP = 107
m∠RQP = 52
m∠RPQ = x
m∠QRP + m∠RQP + m∠RPQ = 180°
107 + 52 + x = 180
159 + x = 180
x = 21°
m∠RPQ = x = 21°
m∠RPQ + m∠YPQ = 180°
21° + m∠YPQ = 180°
m∠YPQ = 159°
A recipe for 1 batch of cookies calls for 1/3 cup of oil. You have 3/4 cup of oil. Do you have enough oil for 2 batches of cookies? She walks 1/2 mile from her home to the bus stop. She then travels 2 miles on the city bus. In miles, how far does the bus drop her off from school?
Answer:
a) Yes she has enough oil for 2 batches
b) 1/4 miles
Step-by-step explanation:
a) A recipe for 1 batch of cookies calls for 1/3 cup of oil. You have 3/4 cup of oil. Do you have enough oil for 2 batches of cookies?
1 batch of cookies = 1/3 cup of oil
2 batches = x
Cross Multiply
x = 2 × 1/3 cup of oil
x = 2/3 cup of oil will be needed for 2 batches
Subtracting 2/3 for 3/4
= 3/4 - 2/3
= 1/12 cup of oil is left
Yes she has enough oli for 2 batches

A seamstress was hired to make band uniforms for Hinsdale High school. The seamstress bought 148 yards of material. There were 16 students in the concert band and 20 students in the symphonic band. How much material did she have for each uniform?
A. 36/9 yards
B. 37/9 yards
C. 35/9 yards
D. 38/9 yards
Answer:
No estoy seguro, intenta preguntarle a tu profesor
Step-by-step explanation:
The seamstress had 37/9 yards of material for each uniform.
What is division?In mathematics, division is a process of dividing a number into equal parts and calculating the maximum number of equal parts that can be made.
How to solve it?Given that total amount of material = 148 yards
number of students in the concert band = 16
number of students in the symphonic band = 20
Total number of students = number of students in the concert band + number of students in the symphonic band
= 16 + 20 = 36
For 36 students, there are 148 yards of material.
Then for 1 student, there are 148/36 = 37/9 yards of material.
Therefore the seamstress had 37/9 yards of material for each uniform. So, option B is correct.

1. 2n - 4 + 6n
2. -15 + 9m
3. 19a - 7 - 3a + 12a
4. 6(x - 3) + ( 2x - 9)
5. (3x + 8) - 6 (2.5x - 3)
Answer:
1. n = 1/2
2. m = 5/3 or 1 2/3
3. a = 1/4
4. x = 27/8
5. x = 13/6
Step-by-step explanation:
I'm just going to explain step 5 as that is what you specifically needed help with.
First, simplify the second term of the equation:
-6(2.5x-3)
= -15x + 18
(this was done by multiplying -6*2.5x which is 15x and -6(-3) which is 18)
Now, add this simplified second term back to the first term:
3x + 8 - 15x + 18
(the parentheses are unnecessary now because it is all just addition and subtraction, so the order doesn't matter)
Simplify:
-12x + 26 = 0
= -12x = -26
= x = -26/-12
= x = 13/6
