What is modulus of a real number?Modulus of a real number, also called absolute value, is non-negative result of the input value.
This is defined as:
[tex]|x| = x ; \text{ (x is non-negative)}\\\\|x| = -x ; \text{ (x is negative)}[/tex](so that the outer negative makes the negative number positive).
Example:
[tex]|5| = 5\\|-5| = -(-5) = 5[/tex]
What is magnitude and sign?A number has both magnitude(its absolute value) and its sign(positive or negative).
If numbers are negative, the more their magnitude increases, the lesser they become.
If numbers are positive, the more their magnitude increases, the greater they become.
Thus, for -5, the magnitude is 5, and sign is –ve.
Also, positive numbers > 0 > negative numbers.
For given case, we get:
-4 = -4|-6| = 63 = 3-2 = -2|5| = 5Arranging, we get:
-4 < -2 < 3 < 5 < 6

At a cost of 200, your club bought 175 frisbees to sell at the pep rally. You plan on selling them for $5 each. What is the domain of the function?
Answer:
Domain: {0, 1, 2, ..., 175}.
Step-by-step explanation:
We are given that a club bought 175 frisbees at a cost of $200 which you plan to sell for $5 each.
We are to find the domain of this function.
Domain is actually the input into a function which is the x value.
Here sales = 5x where x represents the number of frisbees sold.
So the profit will be:
Profit = Sales - Cost = 5x - 200
Here in this case, the domain would be the number of frisbees sold which is between 0 to 175.
A parachutist’s speed during a free fall reaches 180 miles per hour. What is this speed in feet peer second? At what speed, how many feet will the parachutist fall during 20 seconds of free fall? In your computations, use the fact that 1 mile is equal to 5280 feet. Do not round your answer
Answer:
1. 264 ft/s
2. 5280 feet
Step-by-step explanation:
Changing miles per seconds to feet per hour
If 1 mile= 5280 feet
180 miles=?
[tex](180*5280)/1 = 950400[/tex]
=950400 feet
1 hour= 60×60 seconds = 3600
180 miles/hour = feet/sec = 950400/3600 =264 ft/s
To find the number of feet the parachutist fall during 20 seconds;
Distance= speed × time
=264×20 = 5280 feet

Ginger is solving for 'x' in a quadratic equation to find the amounts by which the length and width of the original 9 ft by 6 ft patio must be increased to achieve an area of 88 sq ft.
Explanation:The student is working on a quadratic equation derived from the area of a rectangle. The original dimensions of the patio are 9 ft by 6 ft, which, when both the length and width are increased by the same amount 'x', the new area becomes 88 sq ft. Ginger is thus solving the equation (6 + x)(9 + x) = 88 using the zero product property.
By expanding this, we get a quadratic equation in the form of x^2 + 15x + 54 = 88, which can be simplified to x^2 + 15x - 34 = 0. The zeros of this function will give us the values of 'x' where the new dimensions of the patio result in an area of 88 sq ft. Consequently, the solutions 'x' are the amounts by which the length and width of the original patio would need to be increased to reach the new area.
A 4000 kg truck is parked on a 7.0° slope. How big is the friction force on the truck?
Answer:
4777.28 N
Step-by-step explanation:
The gravitational force down the slope is given by the formula;
(mass *g * sin θ )
where;
θ is the angle of inclination of the slope
g is the gravitational pull
We plug in the given values into the above expression;
(4,000 x 9.8 x sin 7) = 4777.28 N.
The frictional force must equal to 4777.28 N (pointing up the slope).
Final answer:
To calculate the friction force acting on a 4000 kg truck parked on a slope, the component of the truck's weight acting down the slope is determined and found to be approximately 4780 N. This value represents the maximum static friction force available to prevent the truck from sliding.
Explanation:
The question is asking to calculate the friction force acting on a truck parked on a slope. To find the friction force, first, we need to calculate the component of the truck's weight that is acting down the slope. This can be found with the formula Wparallel = mg sin(θ), where m is the mass of the truck, g is the acceleration due to gravity (9.8 m/s²), and θ is the angle of the slope.
The truck's weight component acting along the slope is:
Wparallel = 4000 kg * 9.8 m/s² * sin(7°) ≈ 4000 kg * 9.8 m/s² * 0.12187 ≈ 4780 N
The friction force will counteract this downhill force to prevent the truck from sliding. Assuming that the friction force equals the downhill component of the truck's weight to keep the truck stationary, the friction force on the truck is approximately 4780 N. However, without the coefficient of friction, this represents the maximum static friction force that could occur before the truck would start to slide down the slope.

Answer:
[tex]g(x)= 3x-2[/tex], graph shifted 2 units down.
Step-by-step explanation:
[tex]g(x)= 3x-2[/tex]
g(x) = 3x is a parent function.
When we compare the graph of parent function g(x)= 3x with [tex]g(x)= 3x-2[/tex], negative 2 is added at the end
f(x)---> f(x) + a , the graph will be shifted 'a' units up
f(x)-> f(x) -a , the graph will be shifted 'a' units down
[tex]g(x)= 3x-2[/tex], In this g(x) we have -2 at the end.
So the graph will be shifted 2 units down.
The graph of 3x - 2 is a vertical translation by 2 units down of the function f(x) = 3x
Translation of functions and graphsAccording to the question, we are given the parent function f(x) = 3x, we need to determine the relationship between the parent function and g(x) = 3x - 2
If the function f(x) translate by k units downwards, the resutlting function will be expressed as h(x) - k.
Hence if h(x) = 3x translate by 2 units downwards, the resulting function will be expressed as 3x - 2.

The line AB←→ passes through the points A(−3,6) and B(5,−2).
Which equations could be for AB←→ in point-slope form?
MULTIPLE CHOICES
y+2=−4(x−5)
y−6=−(x+3)
y=−x+3
y+2=−(x−5)
y−2=−(x−1)
y+2=x−5
y−6=x+3
y−6=−4(x+3)
y - 6 = -(x + 3) and y + 2 = - (x - 5).
The line AB passes through the points A(-3, 6) and B(5, -2). Find the point-slope form.
First, we have to calculate the slope using the equation m = (y₂ - y₁)/(x₂ - x₁):
x, y
A(-3, 6)
B( 5,-2)
m = [-2 - (6)]/[5 - (-3)] = (-2 - 6)/(5 + 3)
m = -8/8
m= -1
Writing the point-slope form equation as (y - y₁) = m (x - x₁), with A(-3, 6):
y - 6 = -1[(x -(-3)]
y - 6 = - (x + 3)
Writing the point-slope form equation as (y - y₁) = m (x - x₁), with B(5, -2):
y - (-2) = - (x - 5)
y + 2 = - (x - 5)

Let’s say that our first number is x. We know, two consecutive odd numbers have difference of 2.Now,x + (x+2) + (x+2+2) + (x+2+2+2) = 40Or, 4x + 12 = 40Or, 4x = 40 - 12 = 28Or, x = 28/4 = 7The second odd number in the sequence = x+2 = 7+2 = 9.
Answer:
9 is the second number in this sequence
Step-by-step explanation:
So if n is the first integer in this sequence, then the following are true of the sequence of consecutive odd numbers (just means the odd integer right after):
First integer: n
Second integer: n+2
Third integer: n+4
Fourth integer: n+6
-------------------------------
Sum of these integers are 4n+12=40
Subtract 12 on both sides: 4n =28
Divide both sides by 4: n =7
So first integer 7
Second integer: 9
Third integer: 11
Fourth integer: 13
When you add these up you do get 40!
