Sample #1:
The number of teenagers that get less than 8 hours of sleep each night include the sum of teenagers that get less than 4 hours, teenagers that get between 4 and 6 hours, teenagers that get between 6 and 8 hours.
Thus, we have

If there is more than one answer, separate them with commas. Select "None" if applicable.
Part: 0/2
Part 1 of 2
Zero(s) of k:
The zeroes of the function k(x)=15x³-48x²-48x are 0, 4 and -4/5.
The function provided is a cubic polynomial.
There will be three zeroes in total for the function k(x).
K(x) = 15x³-48x²-48x
If we put x = 0,
We can see that k(x) becomes zero,
So we can say that 0 is a solutions for this function,
Now,
K(x) = x(15x²-48x-48)
Solving 15x²-48x-48 seperately using quadratic formula,
a = 15
b = -48
c = -48
x = (-b+√D)/D and (-b-√D)/D
D = b²-4ac.
D = (-48)²-4(15)(-48)
D= 5184.
√D = 72
putting all the values to find x,
x = (-(-48)+72)/30 and (-(-48)+72)/30
x = 4 and -4/5.
our function becomes,
k(x) = x(x-4)(x+4/5)
so the zeroes are 0, 4, -4/5.

A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 3ft and a diameter of 8ft. The tank will be made from metal (including its top and bottom). If the metal costs $29 for each square foot, how much will the metal cost in total?
The total cost of the metal needed to cover the tank shaped like a metal is $5,099.36.
What is the total cost?In order to determine the total metal cost, we are to first calculate the total surface area of the tank. Since the tank is a closed cylinder, we are to determine the total surface area of a cylinder.
The total surface area of a closed cylinder can be determined by adding the area of all its faces.
Total surface area of the closed cylinder = 2πr(r + h)
Where:
r = radius = diameter / 2 = 8/2 = 4ft
h = height
π = pi = 3.14
(2 x 3.14 x 4)(4 + 3)
25.12 x 7 = 175.84 ft²
Total cost of the metal = $29 x 175.84 = $5,099.36

The equation that calculates the time taken to get to Springfield is x = 926/57
What is rate?Rate is used to establish the relationship between two quantities of different units. one of the quantity is usually expressed to unity in order to estimate the change in the other quantity.
If Hillwood and Springfield are 926 mile apart, and the speed taken to get to Springfield is 57miles per hour.
Let the time taken to get to Spring field be x.
Then if 57 miles is covered in an hour and it takes x hours to get to the destination
It means total distance covered is 57 × x
This distance is equal to the distance from Hillwood to Springfield which is 926 miles.
Equating both equations.
57x = 926

Which of the following quantities are directly proportional? (Answer if they are directly proportional or not) PLS HELP ASAP
A) distance and time traveled if speed is a constant 77 mph
B) speed and time if the distance traveled is 110 miles
C) the price per item and the number of items bought if the amount of money spent is constant
The only quantities that will be directly proportional are; A) distance and time traveled if speed is a constant 77 mph
Which Quantities are Directly Proportional?
Direct proportionality means the change of a similar kind.
For example, as pressure increases, density also increases, which means both the parameters (pressure and density) are experiencing a similar kind of change i.e. increment in their magnitude.
Looking at the given options;
A) Distance and time traveled if speed is a constant 77 mph.
Now, formula for speed is;
Speed = Distance/Time
Thus, if speed is constant, then it means that distance varies directly with the time because as distance increases, then time also increases.
B) We are told that the distance traveled is 110 miles.
Distance = Speed * time.
Thus, speed and time vary indirectly with the time because as one increases, the other decreases
C) Since the amount of money spent is constant, then it means that;
Amount spent = Price per item * number of items

which point most closely approximates the difference of B and A, that is (B -A) ?
Point (C) C closely approximates the given mathematical operation that is the difference between B and A (B - A).
What are mathematical operations?An operation, also known as an "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the operations that are most frequently studied. A constant is an operation of arity zero, also known as a nullary operation. An example of an operation of arity 3, also known as a ternary operation, is the mixed product.So, when we add up 2 numbers let's say A and B, the result is always a 3rd number which is C.
A + B = CSimilarly, when we subtract a number from another number (B - A), the result is always a third number C.
B - A = CSo, (C) C closely approximates the difference between B and A (B - A).
Therefore, point (C) C closely approximates the given mathematical operation that is the difference between B and A (B - A).

System of linear equationsA system of linear equations is a set of equations in which every equation is linear., in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
This caseIn this case, a system of linear equations must be proposed taking into account that:
"c" is the number of cheeseburgers sold on Thursday."h" is the number of hamburgers sold on Thursday.You know:
A local hamburger shop sold a combined total of 449 hamburgers and cheeseburgers on Thursday. There were 51 fewer cheeseburgers sold than hamburgers.The system of equations to be solved is
h + c= 449
h= c - 51
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, substituting the second equation in the first you get:
c - 51 + c= 449
c+ c= 449 + 51

Find the equation of a line parallel to 2x-2y=-4 that passes through the
point (3,9).
The line which is parallel to 2x-2y=-4 that passes through the
point (3,9) is x-y = -6.
Given that, 2x-2y = -4 passes through the point (3,9) then we have to find the equation of a line which is parallel to the given equation of line.
Let's proceed to find the equation of the line.
The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).
Using the slope-intercept formula, the equation of the line is:
y = mx + b
where,
m = the slope of the line
b = y-intercept of the line
(x, y) represent every point on the line
x and y have to be kept as the variables while applying the above formula.
2x-2y = -4
-2y = -4-2x
y = -4/-2 - 2x/-2
y = 2+x
y = x+2
On comparing with y = mx+b
m = 1 and b = 2
As the lines are parallel then the slope of other line will also be same i.e., m = 1
The point from which it is passes is (3,9)
⇒ x₁ = 3 and y₁ = 9
y-y₁ = m(x-x₁)
⇒ y-9 = 1(x-3)
⇒ y-9 = x-3
⇒ y = x-3+9
⇒ y = x+6
⇒ x-y = -6
Therefore, the line which is parallel to 2x-2y=-4 that passes through the
point (3,9) is x-y = -6.
Hence, x-y = -6 is the required answer.

Which percent is larger 5 , 15 or 20?
Write the slope intercept form for the points through (-4,-5) and (0,2)
Answer:
y = (7/4)x + 2
Step-by-step explanation:
(-4, -5) and (0, 2)
(x₁, y₁) (x₂, y₂)
y₂ - y₁ 2 - (-5) 2 + 5 7
m = ------------- = ------------- = ------------- = --------
x₂ - x₁ 0 - (-4) 0 + 4 4
(it doesn't matter which points you put)
y - y₁ = m(x - x₁)
y - 2 = (7/4)(x - 0)
y - 2 = (7/4)x - 0
+2 +2
----------------------------
y = (7/4)x + 2
