Step-by-step explanation:
You are playing in the NBA Playoffs and attempt a 3-point shot as the buzzer sounds for the end of the
game, if you make the shot your team wins! Your basketball is is traveling on a path described by the
following function: b(x) = -x2 +1.36x + 2. The net is on a level described by the following function:
n(x) = 3 between (8 < x < 8.5). Will you make the shot and win the playoffs?
You may work alone or in a group of up to 3 students total.
BONUS: How high in the air will the basketball be at its highest point?
UNITS: x is in meters, y is in meters.
The quadratic function for the path of the basketball as it is thrown indicates;
The path of the basketball will not make the shot
The height reached is about 5.24 meters
What is a quadratic function?A quadratic function is a function of the form; f(x) = a·x² + b·x + c, where a ≠ 0, and a, b, c, are numbers.
The function for the path of the basketball is; b(x) = (-1/7)·x² + 1.36·x + 2
The function for the location of the basketball net is; n(x) = 3 and (8 < x < 8.5), where;
n(x) = The vertical height of the basketball
Plugging in the value of the n(x) = b(x), to check if equations have a common solution, we get;
b(x) = n(x) = 3 = (-1/7)·x² + 1.36·x + 2
(-1/7)·x² + 1.36·x + 2 - 3 = 0
(-1/7)·x² + 1.36·x - 1 = 0
(1/7)·x² - 1.36·x + 1 = 0
Solving the above equation, we get;
x = (119 - √(9786))/(25) ≈ 0.803, and x = (119 + √(9786))/(25) ≈ 8.717
Therefore, the x-coordinates of the height of the path of the basketball when the height is 3 meters are 0.803 and 8.717, neither of which are within the range (8 < x < 8.5), therefore, the baseketball will not go through the net and the path will not make the shot.
Bonus; The x-coordinates of the highest point of a quadratic function, f(x) = a·x² + b·x + c is; -b/(2·a)
Therefore, the x-value at the highest point of the equation, b(x) = (-1/7)·x² + 1.36·x + 2 is; x = -1.36/(2 × (-1/7)) = 1.36 × 7/2 = 9.52/2 = 4.76
The height of the highest point is; b(9.52) = (-1/7)·(4.76)² + 1.36·(4.76) + 2 ≈ 5.24 meters

The mean height of three boys is 150 centimeters. The mean height of two girls is 145.Find the mean height of five students
A mean is an arithmetic average of a set of observations. The mean height of the five students is 148.
What is Mean?A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
Given that the mean height of three boys is 150 centimeters. Therefore, the sum of height of the three boys is,
Mean Height of boys = Sum of height of boys / Number of boys
150 = Sum of height of boys/ 3
Sum of height of boys = 150 x 3 = 450
Also, given that the mean height of two girls is 145 centimeters. Therefore, the sum of height of the two girls is,
Mean Height of girl = Sum of height of girls/ Number of girls
145 = Sum of height of girls/ 2
Sum of height of girls = 145 x 2 = 290
Further, the mean height of five students is,
Mean height of five students = Sum of height of students / Number of students
Mean height of five students = (450 + 290)/ 5
Mean height of five students = 740 / 5
= 148
Hence, the mean height of the five students is 148.

Find the x-intercept and y-intercept of the line.
8x-5y = 18
Answer:
Y intercept (9/4,0)
X intercept (0,-18/5)
Step-by-step explanation:
The x-intercept is (2.25, 0) and the y-intercept is (0, -3.6).
To find the x-intercept and y-intercept of the line represented by the equation 8x - 5y = 18, we need to set one of the variables to zero and solve for the other variable.
1. X-Intercept (where y = 0):
To find the x-intercept, set y = 0 in the equation:
8x - 5(0) = 18
8x = 18
Now, solve for x:
x = 18/8
x = 9/4 or 2.25
So, the x-intercept is (2.25, 0).
2. Y-Intercept (where x = 0):
To find the y-intercept, set x = 0 in the equation:
8(0) - 5y = 18
-5y = 18
Now, solve for y:
y = 18/(-5)
y = -18/5 or -3.6
So, the y-intercept is (0, -3.6).
Therefore, the x-intercept is (2.25, 0) and the y-intercept is (0, -3.6).

Answer:
(a) m = 0.47, b = 154.30
(b) b = fixed costs, listed as insurance and car payments.
Step-by-step explanation:
(a) All you're required to do here is recognize that the fixed costs of $154.30 for insurance and car payments represent the constant part of the monthly expense. And, the $0.47 per mile represents the mileage-related part of the monthly expense. Of course the mileage-related charge is the product of the per-mile charge ($0.47) and the number of miles (x).
Then the monthly charge is ...
monthly cost = mileage-related cost + constant (fixed) cost
y = mx + b
y = 0.47x + 154.30 ⇔ m = 0.47, b = 154.30
__
(b) The 'b' in the equation is the fixed monthly cost: $154.30 for insurance and car payment.

employees at an arcade are paid according to the number of hours worked as shown in the graph
Answer:
B, C, G
Step-by-step explanation:
If we look at the graph, it shows that if an employee works for 5 hours, then they will earn $36.25.
We can take 36.25 and divide that by 5 to get the hourly wage.
36.25 ÷ 5 = 7.25
We now know that employees get $7.25 every hour.
Using this we can look back to the graph.
'A' says that if an employee does not work, they will earn $7.25.
We know that this is wrong because if you do not work, then you do not earn money.
Let's look at 'B'.
If employees work for one hour, they will earn $7.25
We know this is correct because we now know the hourly wage.
Let's look at 'C'
If employees work for 4 hours, then they will get a revenue of $29.
We can figure this out by using this equation.
number of hours × hourly wage = total payment
4 × 7.25 = 29
Then this means that this is correct.
Let's look at 'D'
It says that if employees work for 10 hours, they will earn $73
Let's use that same equation again.
10 × 7.25 = 72.5
Employees earn $72.5 for working 10 hours, not $73.
So, this is obviously incorrect.
Let's look at 'E'
It says that if employees work for 3.5 hours, they will get a revenue of $21.75.
3.5 × 7.25 = 25.375
Therefore, this is incorrect.
Now let's take a look at 'F'.
It says that if employees work for 7.25 hours, then they earn $1.
This is incorrect.
And lastly, 'G'.
We know that if you do not work, then you do not earn money.
Therefore, A, B and G are the correct answers.

The solution to the linear equations in three variable are x = 5, y = -11, and z = 3.
What is a linear equation?It is defined as the relation between three variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The three linear equations:
2x - y + 4z = 33 ..(i)
x + 2y - 3z = -26 ...(ii)
-5x - 3y + 5z = 23 ...(iii)
After solving the above linear equation by elimination method:
From the equation (i):
\(x=\dfrac{33+y-4z}{2}\) ....(iv)
Plug the above value in the equation (ii) and (iii)
\(\rm \dfrac{33+y-4z}{2}+2y-3z=-26\\\\\\\\ -5\cdot \dfrac{33+y-4z}{2}-3y+5z=23\)
After solving the above linear equation in two variables:
y = -11
z = 3
Plug the above values in the equation (iv)
We get the value of x:
x = (33-11-3(4))/2
x = (33-11-12)/2
x = 10/2
x = 5
Thus, the solution to the linear equations in three variable are x = 5, y = -11, and z = 3.

Answer:
a) 7 m
b) 22 cm
Step-by-step explanation:
Given plans at a scale of 1 : 50, you want (a) the actual length corresponding to a plan length of 14 cm, and (b) the plan length corresponding to an actual length of 11 m.
ProportionThe actual lengths are wanted in meters, so we can rewrite the scale to translate between plan cm and actual m.
plan : actual = 1 cm : 50 cm
= 1 cm : 0.5 m
= 2 cm : 1 m
a) 14 cmMultiplying the scale by 7, we have ...
2 cm : 1 m = 14 cm : 7 m
The actual length is 7 meters.
b) 11 mMultiplying the scale by 11, we have ...

Due to the law of alternate interior angles, we can see that one of the angles in the triangle is equal to 35 degrees as well (please see the picture attached).
We're given that one of the exterior angles of the triangle is equal to 105. The exterior angle of a triangle will always be equal to the sum of the two opposite interior angles. Knowing this, we can write:
x+35=105
Subtract both sides by 35
x+35-35=105-35
x=70
Therefore, the value of x is 70 degrees.

Answer: D. Square
Step-by-step explanation:
The shape created by the cross section of the cut through a square pyramid is a square.
To see why, imagine the pyramid sitting on a table with its square base flat against the surface. The cut goes through the vertex, which is the point at the top of the pyramid. Since the cut is perpendicular to the base, it divides the pyramid into two smaller pyramids with congruent, but not identical, bases. Each of these smaller pyramids has a triangular base that is an isosceles right triangle. The two triangles share a common hypotenuse, which is the line of the cut.
The cross section of the cut is the shape formed where the two triangles meet along the hypotenuse. Since both triangles are congruent and the hypotenuse is the same for both, the cross section is a square. The sides of the square are equal to the base of the original pyramid, which is one of the legs of the isosceles right triangles formed by the cut. Therefore, the answer is D, a square.
Kennedy and Olivia go to the movie theater and purchase refreshments for their friends.
Kennedy spends a total of $77.50 on 12 bags of popcorn and 2 drinks.
Olivia spends a total of $51.00 on 3 bags of popcorn and 6 drinks.
Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink.
Using these equations, determine and state the price of a drink, to the nearest cent.
Answer:
6x + y = 38.75
x + 2y = 17
price of drink is $5.75
Step-by-step explanation:
Let the price of popcorn be x
Let the price of drink be y.
price of 12 bags of popcorn will be 12x
price of 2 drinks will be 2y
it is given that "Kennedy spends a total of $77.50 on 12 bags of popcorn and 2 drinks."
thus
12x + 2y = 77.50
dividing LHS and RHS by 2 we have
12x/2 + 2y/2 = 77.50/2
=> 6x + y = 38.75 _________(1)
__________________________________________________
price of 3 bags of popcorn will be 3x
price of 6 drinks will be 6y
it is given that "Olivia spends a total of $51.00 on 3 bags of popcorn and 6 drinks."
thus
3x + 6y = 51.00
dividing LHS and RHS by 3 we have
3x/3 + 6y/3 = 51/3
=> x + 2y = 17 _____________(2)
__________________________________________________
Thus we have two equation
6x + y = 38.75 _________(1)
x + 2y = 17
=> x = 17 - 2y
putting this value of x in equation 1 we have
6( 17 - 2y) + y = 38.75
=> 102 - 12y + y = 38.75
=> 102 - 11y = 38.75
=> -11y = 38.75 -102
=> -11y = -63.25
=> y = -63.25/-11 = 5.75
as we have x = 17 - 2y
using 5.75 in place of y
x = 17 - 2(5.75 )
=> x = 17 - 11.5
=> x = 5.5
Thus, system of equations are
6x + y = 38.75
x + 2y = 17
price of drink is $5.75
