Step-by-step explanation:
In general, for all problems like this, remember the acronym VOHI:
vertical outside, horizontal inside.
1. The parent function here would be [tex]f(x)=x^{2}[/tex]. 4 has been subtracted from the inside, so it is a horizontal change. You might think that it is moving left 4, but it's actually moving right 4. There is a reason for this, but it's not necessary for you to know right now. All you need to remember is that when inside the parentheses, minus means moving right, and plus means moving left. You also have a 9 added to the outside. Vertical outside. This is a vertical change, meaning up and down. This function has been moved right 4 and up 9.
2. First, the parent function is again [tex]f(x)=x^{2}[/tex]. This time, we have [tex]\frac{1}{4}[/tex] on the outside of our function. This means it is a vertical transformation. When the value on the outside is > 1, it is a vertical stretch. When the value is between 0 and 1 (0<a<1), it is a vertical shrink. [tex]\frac{1}{4}[/tex] is between 0 and 1. So, this is a vertical shrink by a factor of [tex]\frac{1}{4}[/tex]. Next, there is a 6 on the inside of the parentheses, meaning a horizontal translation. Remember from problem 1, though, minus=right and plus=left. So, this function has been vertically shrunk by [tex]\frac{1}{4}[/tex] and moved left 6.
3. Again, parent function: [tex]f(x)=x^{2}[/tex]. This one just has [tex]\frac{3}{2}[/tex] on the outside. We know that it's on the outside because otherwise there would be parentheses around both [tex]\frac{3}{2}[/tex] and x. There is not, so it is outside. Outside, vertical. This is a vertical change. Looking back at problem two, when a value is >1, which this is, it is a vertical stretch. So this function has a vertical stretch by [tex]\frac{3}{2}[/tex].

Transformation involves changing the position and/or size of a function.
The transformations are:
Translate f(x), 4 units right, and 9 units up.Translate f(x), 4 units left, then compress f(x) vertically by 1/4Vertically stretch f(x) by 3/2[tex]\mathbf{1.\ f(x) = (x - 4)^2 +9}[/tex]
The above function is a square function, and the parent function is:
[tex]\mathbf{f(x) = x^2}[/tex]
First, the function is translated right by 4 units (this is represented by subtracting 4 from x.
i.e.
[tex]\mathbf{f(x) = (x - 4)^2}[/tex]
Next, the function is translated up by 9 units (this is represented by adding 9 to the value of y.
i.e.
[tex]\mathbf{f(x) = (x - 4)^2 + 9}[/tex]
So, the transformation from the parent function is: Translate f(x), 4 units right, and 9 units up.
[tex]\mathbf{2.\ f(x) = \frac 14(x + 4)^2}[/tex]
The above function is a square function, and the parent function is:
[tex]\mathbf{f(x) = x^2}[/tex]
First, the function is translated left by 4 units (this is represented by adding 4 from x.
i.e.
[tex]\mathbf{f(x) = (x + 4)^2}[/tex]
Next, the function is vertically compressed a factor of 1/4 (this is represented by multiplying the function by 1/4
i.e.
[tex]\mathbf{f(x) = \frac 14(x + 4)^2}[/tex]
So, the transformation from the parent function is: Translate f(x), 4 units left, then compress f(x) vertically by 1/4
[tex]\mathbf{3.\ f(x) = \frac 32x^2}[/tex]
The above function is a square function, and the parent function is:
[tex]\mathbf{f(x) = x^2}[/tex]
The function is vertically stretched a factor of 3/2 (this is represented by multiplying the function by 3/2
i.e.
[tex]\mathbf{f(x) = \frac 34 \times x^2}\\[/tex]
[tex]\mathbf{f(x) = \frac 34 \timex x^2}[/tex]
So, the transformation from the parent function is: Vertically stretch f(x) by 3/2

Answer:
They need to sell 3 tees, and incurred $60.
Step-by-step explanation:
What is the revenue equation? R = 20x, where x is the # of tees sold.
What is the cost equation? C = 5x + 45, where x is the # of tees sold.
Set those two equations equal, we get:
20x = 5x + 45, 15x = 45, x = 3.
3*5 + 45 = 60.

How much pure alcohol must a nurse add to 10 cubic centimeters of a 60% alcohol solution to strengthen it to a 90% solution? Plsss help ASAP
10 cubic centimeters of a 60% alcohol solution, would mean 10 x 60% = 6 cc is alcohol the other 4 cc is water.
To make a 90% solution, the water would be 10% of the solution.
If 4 cc is 10%, the total is 40 cc.
40 - 10 = 30 cc
30 cubic centimeters needs to be added.

Answer:
[tex]\huge\boxed{m\angle 1 = 131 \textdegree}[/tex]
[tex]\huge\boxed{m\angle 2 = 49 \textdegree}[/tex]
[tex]\huge\boxed{m\angle 3 = 112 \textdegree}[/tex]
Step-by-step explanation:
We can use basic angle relationships to find the measure of angles 1, 2, and 3 here.
First off, we know that the 49° angle and m∠1 are supplementary. This means that their angle measures will add up to 180°.
Since we know one, we can find the other easily.
[tex]x + 49 = 180\\\\x = 180-49\\\\x = 131[/tex]
So m∠1 = 131°.
We also know that m∠2 is opposite to the 49° angle. This means that m∠2 is also 49°.
Now, we know that m∠3 is also opposite to the 112° angle. Therefore, their angle measures are the same, and m∠3 is also 112°.

Find;
i) Angle PCQ
ii)The area of the sector PQRC
iii)The area of the minor segment
I need help plsssssssss
Answer:
A
Step-by-step explanation:
If you follow the dotted lines and bring all the lines together,
angle8 = angle4 (corresponding angles)
angle8 = angle5 (vertically opposite angles)
angle5 = angle1 (corresponding angles)
Therefore, angle8 is basically the same as angles 1 and 4

Every week, a car dealer ship sells at least 5 minivans. Write an inequality that represents this situation. Let c represent the number of minivans sold each week.
Answer:
An inequality 'c ≥ 5' represents this situation.
Step-by-step explanation:
We know that the inequality symbol '≥' represents 'at least'.
For example, 'x≥y' means 'x' is greater than or equal to b. It means 'x' is at least equal to 'y'.
Let 'c' represent the number of minivans sold each week.
As a car dealer ship sells at least 5 minivans. It means the dealer can also sell more than 5.
i.e. c ≥ 5
Therefore, an inequality 'c ≥ 5' represents this situation.

The cost of 4 pounds of bananas is $3.52. What is the constant of proportionality that relates the cost of dollars, y, to the number of pounds of bananas, x?
Answer:
B. $0.88
Step-by-step explanation:
x = number of bananas
y = cost of bananas in dollars
Given that 4 bananas cost $3.52, the constant of proportionality that relates cost of bananas, y, to the number of pounds of bananas, x = y/x
y = 3.52
x = 4
Therefore:
Constant of proportionality = [tex] \frac{3.52}{4} = 0.88 [/tex].

Ordered Pairs
It's given the equation
y = x + 2
Since there are no restrictions for the values of x and y, it has infinitely many solutions, i.e. any ordered pair of values (x,y) that make true the equation is a solution.
We can pick any value for x and then calculate the corresponding value for y as follows:

If we multiply 0.8 by 1/50, we get 0.8 × 1/50 = 0.8/50 = 0.016 meter. So, we can say 0.016 meter wide should the door be on the scale drawing, if the ratio is 1 to 50.
Answer:
the ratio is 1:50
this means that 1 meter in the drawing is equal to 50 meters in real life, but that is a complicated way of stating something simple since drawings are not generally measured in meters.
the door is 0.8 meters wide or 80 centimeters wide
in our drawing, the door should be 80 / 50 = 1.6 centimeters wide
the whole purpose of a scale is to allow us to work with smaller units, that is why we have to work with them. It is true that 0.016 meters = 1.6 centimeters, but as I said before, writing the answer in meters just complicates things and makes them harder to understand. You could also say it is 0.000016 kilometers wide and it would be right, but too confusing.
