Answer:
f(x, y) = (-x-3, y-3)
Step-by-step explanation:
Reflection across the y-axis is ...
r(x, y) = (-x, y)
Translation left and down 3 units each is ...
t(x, y) = (x -3, y -3)
Then the composition of reflection then translation is ...
f(x, y) = t(r(x,y)) = t(-x, y)
f(x, y) = (-x-3, y-3)

The curved surface area of a cylinder is
250 cm2. If the cylinder is 12 cm high, find
its volume.
9514 1404 393
Answer:
414.5 cm³
Step-by-step explanation:
The lateral area of a cylinder is given by the formula ...
LA = 2πrh
Then the radius is ...
r = LA/(2πh)
The volume of the cylinder is given by ...
V = πr²h
Using the above expression for r, this becomes ...
V = π(LA/(2πh))²h = LA²/(4πh)
V = (250 cm²)²/(4π·12 cm) ≈ 414.47 cm³
The volume of the cylinder is about 414.5 cm³.

Explanation:
Each tickmark on the graph represents a distance of 2 units. From A to P is 4 tickmarks, so that corresponds to 2*4 = 8 units. That's one of the bases. The other base is TR = 2. The bases are parallel to one another.
The height is always perpendicular to the base, and the height is 2*3 = 6 units.
So we have
b1 = 8, b2 = 2, and h = 6
Which means,
A = h*(b1+b2)/2
A = 6*(8+2)/2
A = 6*10/2
A = 60/2
A = 30
------------------------------
As a slightly longer alternative, we can plot points at (-2, 0) and (-2, -2). Let's call these two points M and N respectively. These two points subdivide the trapezoid into three pieces: Two triangles sandwiching a rectangle.
Triangle TMP has area of base*height/2 = 6*4/2 = 12Rectangle TMNR has area of length*width = 6*2 = 12Triangle RNA has area of base*height/2 = 6*2/2 = 6Add up those sub-areas to get the full area of the trapezoid:

Answer:
9x^2 + 42x + 16
Step-by-step explanation:
f(g(x))
Plug in the expression for g(x)
f(g(x)) = f(-3x - 5)
f(x) = x^2 - 4x - 9
For every x in f(x) replace it with -3x - 5
f(-3x - 5) = (-3x - 5)^2 - 4(-3x -5) -9
Expand
f(-3x - 5) = (9x^2 + 30x + 25) + (12x + 20) - 9
Combine like terms
f(-3x - 5) = 9x^2 + 42x + 16
f(g(x)) = 9x^2 + 42x + 16

It helps you find missing numbers on a number line. For example, if 4 cookies cost $2, you can use the unit rate of $0.50/cookie to find out how much 8 cookies cost."
In the above case, we have several clues about the rate. The first relationship on the line is between 1 and 3.
But it only makes when we compare it to other iterations on the line such as 2 and 6.
Note that we can establish a relationship here which is that the greater number must be divided by three to get the lower number. That is:
3/3 = 1
6/3 = 2
Note well that the relationship between 0, 3, and 6 on the number line tell us that the upper units graduate in progressions of 3. that is:

Akira is setting tables at the restaurant where she works. She starts with a pile of 85 napkins, and she places 6 napkins on every table she sets
Write an equation that shows how the number of napkins remaining, y, depends on the number of tables akira sets, x
Answer: y = 85 - 6x
Step-by-step explanation:
Number of napkins remaining: y
Number of tables set: x
Akira starts out with 85 napkins. So, every time she sets a table, she is losing 6 napkins. The steady rate of napkins lost can be written with the following expression, as she is losing 6 napkins per table.
[tex]-6x[/tex]
These napkins are being removed from the total of 85 napkins:
[tex]85 - 6x[/tex]
The above equation also expresses the number of napkins remaining. Writing it as a proper equation:
[tex]y = 85 - 6x[/tex]
The final answer is: y = 85 - 6x
Find the volume of the composite solid. Round your answer to the nearest hundredth.
Answer:
9,114.81 ft³
Step-by-step explanation:
The solid is composed of a cylinder and a hemisphere
Volume of the solid = volume of the cylinder + volume of the hemisphere
= πr²h + ⅔πr³
Where,
r = 8 ft
h = 40 ft
Plug in the values into the equation
Thus:
Volume of the solid = π*8²*40 + ⅔*π*8³
= 8,042.4772 + 1,072.33029
= 9,114.80729
= 9,114.81 ft³ (nearest hundredth)

Yˆ=9.1411+0.4775X What is the value of Yˆ when a male crab is 23.2417 months old?
Answer:
[tex]Y = 20.239[/tex]
Step-by-step explanation:
Given
[tex]Y = 9.1411 + 0.4775X[/tex]
Required
The predicted value of [tex]Y[/tex] when [tex]X = 23.2417[/tex]
To do this, we substitute [tex]X = 23.2417[/tex] in the given equation

[tex]Y = 20.239[/tex]
What is the measure of missing angle S?
Answer:
60
Step-by-step explanation:
The measure of ∠ATS is 120. The measure of a straight angle is always going to be 180 degrees. So first, we subtract 120 from 180 to find the measure of the interior angle.
∠STR = 180 - 120
= 60
The measure of all the interior angles in the triangle ΔSTR is 180 degrees.
180 - 60 - 60
= 60
The measure of ∠TSR is 60 degrees.

A new online auction site specializes in selling automotive parts for classic cars. The founder of the company believes that the price received for a particular item increases with its age (the age of the car on which the item can be used in years) and with the number of bidders. Use the multiple regression output below to answer the following questions.

a. Use the information above to write out the form of the linear regression model.
b. Interpret each of the estimated regression coefficients of the regression model.
c. Is the founder of the company correct in believing that the price received for the item increases with its age and with the number of bidders? Explain your answer.
Solution :
a). The required linear regression model is
Price = [tex]$-1242.986 + 75.017 \times \text{age of part} + 13.973 \times \text{ number of bidders}$[/tex]
b). The [tex]$\text{p-value}$[/tex] for the variable "Age of part" is 0.0000
Since the [tex]$\text{p-value}$[/tex] is less than 0.05, so it is significant to the model.
The p-value for the variable "Number of bidders" is 0.1940
Since [tex]$\text{p-value}$[/tex] is not less than [tex]$0.05$[/tex], so it is significant to the model.
c). We cannot say that model is significant because variable " the number of bidders" is not significant.
But as both variables have positive coefficient so as the variable increases the price received for the item also increased.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Kala got a prepaid debit card with $15.
Price of Ribbon = 24 cents per yard.
After purchase money left $3.48.
So, Price of Ribbon purchased = 15 - 3.48 = $11.52 = 1152 cents
length of ribbon = 1152/ 24
= 48 yards

17. Identify the amplitude, period, and vertical shift for the
function shown. Then write an equation that represents the curve.
m
A=
B=
P=
C=
f(x)=
Answer:
[tex]f(x)=2cos(x+\frac{\pi}{2})+3[/tex]
Step-by-step explanation:
Because the function is symmetric about the y-axis, using the cosine function is most appropriate.
Refer to the equation for a cosine function:
[tex]f(x)=acos(bx+c)+d[/tex]
Amplitude: [tex]|a|[/tex]
Period: [tex]\frac{2\pi}{|b|}[/tex]
Phase shift: [tex]-\frac{c}{b}[/tex]
Midline: [tex]y=d[/tex]
The amplitude would be the average of the maximum and minimum y-values of the function, which would be [tex]|a|=|\frac{5-1}{2}| =|\frac{4}{2}| =|2|=2[/tex].
The value of [tex]b[/tex] in [tex]\frac{2\pi}{|b|}[/tex] represents the length of the period, so since the length of the period is [tex]2\pi[/tex], this means that [tex]b=\frac{2\pi}{|2\pi|} =1[/tex].
The phase shift, [tex]-\frac{c}{b}[/tex], describes the horizontal shift of a function. Because the phase shift is [tex]-\frac{\pi}{2}[/tex], then we can set up the equation [tex]-\frac{\pi}{2}=-\frac{c}{1}[/tex] where we determine [tex]c=\frac{\pi}{2}[/tex].
The midline (or vertical shift), [tex]d[/tex], is the horizontal line that passes through between the maximum and minimum points, which the function oscillates. In this case, the midline would be located at the line [tex]y=3[/tex], therefore, [tex]d=3[/tex].
Putting all our information together, your final equation is:
[tex]f(x)=2cos(x+\frac{\pi}{2})+3[/tex]
