Given that f(x) = |x|, graph the function g(x) = -f(x + 4).
Answers
Conniving these points and connecting them, we get a V- shaped graph that's reflected vertically and shifted 4 units to the left wing.
To graph the function g( x) = - f( x 4), we need to start with the graph of the function f( x) = | x| and also apply the given metamorphoses. The function f( x) = | x| represents the absolute value function, which is a V- shaped graph symmetric with respect to the y- axis.
First, we shift the graph of f( x) = | x| horizontally by 4 units to the left by replacing x with( x 4). This results in f( x 4). Next, we multiply the entire function by-1, which reflects the graph vertically. This gives us- f( x 4). Combining these metamorphoses, we've the function g( x) = - f( x 4). To graph g( x), we can compass a many points and also draw the graph by connecting them.
Let's start with the original graph of f( x) = | x| and apply the metamorphoses
For f( x) x = -3,-2,-1, 0, 1, 2, 3
f( x) = 3, 2, 1, 0, 1, 2, 3 For
g( x) = - f( x 4) x = -7,-6,-5,-4,-3,-2,-1
g( x) = -3,-2,-1, 0,-1,-2,-3
conniving these points and connecting them, we get a V- shaped graph that's reflected vertically and shifted 4 units to the left wing.

Some friends tell you that they paid $25000 down on a new house and
are to pay $525 per month for 30 years. If interest is 7.8% compounded
monthly, what was the selling price of the house? How much interest
will they pay in 30 years
Answers
Answer: To find the selling price of the house, we can use the formula for the present value of an annuity:
PV = A * ((1 - (1 + r)^-n) / r)
Where:
PV = Present Value
A = Annuity payment per period
r = Interest rate per period
n = Total number of periods
In this case, the annuity payment is $525 per month, the interest rate is 7.8% per year compounded monthly (which is equivalent to a monthly interest rate of 7.8% / 12 = 0.65%), and the total number of periods is 30 years * 12 months/year = 360 months.
Using these values, we can calculate the present value of the annuity:
PV = 525 * ((1 - (1 + 0.0065)^-360) / 0.0065)
PV = 525 * 162.577
PV = $85,192.25
So the selling price of the house was $85,192.25 + $25,000 down payment = $110,192.25.
To calculate the total interest paid over 30 years, we can subtract the total payments from the selling price:
Total payments = $525/month * 360 months = $189,000
Total interest paid = $189,000 - $110,192.25 = $78,807.75
Therefore, the friends will pay $78,807.75 in interest over 30 years.

When a point is reflected over the x-axis, its y-coordinate changes sign.
In this case, the point P has coordinates (4,3).
To reflect it over the line x=3, we need to keep its x-coordinate the same and change its y-coordinate to its opposite.
So, the x-coordinate of the reflected point will still be 4, but the y-coordinate will become -3.

A store owner paid $15 for a book. She marked up the price of the book by 40% to determine its selling price.
Part A
What is the selling price, in dollars, of the book?
Enter your answer in the box.
Part B
A customer buys a different book that has an original selling price of $38. The book is discounted 25%. The customer must pay a 6% sales tax on the discounted price
of the book.
What is the total amount, in dollars, the customer pays for the discounted book?
Enter your answer in the box.
Answers
Answer:
A) $21.00
B) $30.21
Step-by-step explanation:
Part AThe markup is ...
0.40 × $15.00 = $6.00
The selling price is ...
cost + markup = $15 +6 = $21.00
The selling price of the book is $21.00.
__
Part BThe discount is ...
0.25 × $38.00 = $9.50
The selling price is ...
original price - discount = $38.00 -9.50 = $28.50
The tax is ...
0.06 × $28.50 = $1.71
So the total the customer pays is ...
$28.50 +1.71 = $30.21
The customer pays $30.21 for the discounted book.
Answer:
PART A:
The selling price is $21.
PART B
The cost is $30.21
Step-by-step explanation:
In order to use percents in math questions, you have to change the percent to a decimal. 40% in the math question will be .40 (which is the same as just .4) in your calculations.
$15 × 40%
= 15 × .4
= 6
So, $6 is the the amount of the markup. Add $6 to the $15 to determine the selling price.
6 + 15 = 21
The selling price is $21.
25% needs to be changed to .25 for calculations.
6% needs to be changed to .06 for calculations.
$38 × 25%
=38 × .25
= 9.5
This is a discount. subtract .
38 - 9.5
= 28.5
This is the discounted price. Now find tax.
28.5 × .06
= 1.71
Add tax to price.
28.5 + 1.71
= 30.21
The cost is $30.21

If the domain is restricted to the portion of the graph with a positive slope, how are the domain and range of the function and its inverse related?
Answers
If we restrict the domain of the function to the portion of the graph with a positive slope, the domain of the inverse function will be the range of the original function for values of x greater than 4, and its range will be all real numbers greater than or equal to 4.
The given function f(x) = |x – 4| + 6 is a piecewise function that contains an absolute value. The absolute value function has a V-shaped graph, and the slope of the graph changes at the point where the absolute value function changes sign. In this case, that point is x=4.
If we restrict the domain of f(x) to the portion of the graph with a positive slope, we are essentially considering the piece of the graph to the right of x=4. This means that x is greater than 4, or x>4.
The domain of the inverse function, f⁻¹(x), will be the range of the original function f(x) for values of x greater than 4. This is because the inverse function reflects the original function over the line y=x. So, if we restrict the domain of f(x) to values greater than 4, the reflected section of the graph will be the range of f⁻¹(x).
The range of f(x) is all real numbers greater than or equal to 6 because the absolute value function always produces a positive or zero value and when x is greater than or equal to 4, we add 6 to that value. The range of f⁻¹(x) will be all real numbers greater than or equal to 4, as this is the domain of the reflected section of the graph.

What are parallel lines?Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline.
Numerous pairs of angles are created whenever any two parallel lines are intersected by a third line known as a transversal. The other angles are supplementary while some are congruent (equal).
Angles on a straight line sum up 180°
Let us take the line t as our straight line
(7x – 1)° + (9x + 5)° = 180°
(7x + 9x + 5 – 1) = 180
16x + 4 = 180
16x = 180 – 4
16x = 176
(16x)/16 = (176/16)
x = 11
Hence, the value of x is 11.

How much space will a cylindrical water tank occupy if its height is 100 cm and its diameter is 30
find the volume
Answers
Answer:
volume of a cylindrical water tank = 70,650cm³
Step-by-step explanation:
volume of cylinder, V = πr²h
where π = 3.14
h = 100cm
r = ?
given is diameter = 30cm
r = d/2 = 30/2 = 15cm
substituting the values in the formula,
V = 3.14 * 15² * 100
= 3.14 * 225 * 100
= 70,650cm³
Answer:
How much space it would take up: 706.86 square centimeters of floor space and extend vertically to a height of 100 cm
Volume: 706,500 cm³
Step-by-step explanation:
How much space it would take up:
To determine the space occupied by a cylindrical water tank in a room, we need to consider its dimensions and the area it covers on the floor.
The diameter of the tank is given as 30 cm, which means the radius is half of that, 15 cm.
To calculate the space it occupies on the floor, we need to find the area of the circular base. The formula for the area of a circle is A = πr², where A is the area and r is the radius.
A = π(15 cm)²
A = π(225 cm²)
A ≈ 706.86 cm²
So, the circular base of the tank occupies approximately 706.86 square centimeters of floor space.
The height of the tank is given as 100 cm, which represents the vertical space it occupies in the room.
Therefore, the cylindrical water tank would take up 706.86 square centimeters of floor space and extend vertically to a height of 100 cm in the room.
Volume:
To calculate the volume of a cylindrical water tank, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.
First, we need to find the radius by dividing the diameter by 2:
Radius = 30 cm / 2 = 15 cm
Now we can calculate the volume:
V = π(15 cm)²(100 cm)
V = 3.14 * 225 cm² * 100 cm
V = 706,500 cm³
Therefore, the cylindrical water tank will occupy a volume of 706,500 cm³ or 706.5 liters.

A consulting engineer's time is billed at $40 per hour, and her assistant's is billed at $10 per hour. A customer received a bill for $425 fir a certain job. If the assistant worked 5 hours less than the engineer, how much time did each bill on the job?
Engineer: _____ hr
Assistant: ______ hr
Answers
Answer:
Engineer: 9.5 hr
Assistant: 4.5 hr
Step-by-step explanation:
To solve this problem, we can create and solve a system of equations.
Define the variables:
Let x be the number of hours the engineer worked.Let y be the number of hours the assistant worked.Given the engineer's time is billed at $40 per hour, and her assistant's is billed at $10 per hour, and a customer received a bill for $425 for a certain job:
\(40x+10y=425\)Given the assistant worked 5 hours less than the engineer:
\(y=x-5\)Therefore, the system of equations that represents the problem is:
\(\begin{cases}40x+10y=425\\ \quad \qquad \;\;\;y=x-5\end{cases}\)
Substitute the second equation into the first equation to eliminate y:
\(40x+10(x-5)=425\)
Solve the equation for x to find the number of hours the engineer worked:
\(\begin{aligned}40x+10(x-5)&=425\\40x+10x-50&=425\\50x-50&=425\\50x&=475\\x&=9.5\end{aligned}\)
Therefore, the engineer worked 9.5 hours.
Substitute the found value of x into the second equation and solve for y to find the number of hours the assistant worked:
\(\begin{aligned}y&=x-5\\y&=9.5-5\\y&=4.5\end{aligned}\)
Therefore, the assistant worked 4.5 hours.
