Answer:
Step-by-step explanation:
Can't sketch it, obviously, but I can help you understand how to do that on your own. The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] where h and k are the coordinates for the center of the circle. The super-important thing to remember here is that the standard form is ALWAYS (x-h)^2 (the minus being the important part!). That means that if the expression is
[tex](x-2)^2[/tex] for example, it can be rewritten to be understood as
[tex](x-(+2))^2[/tex] where the positive implies movement to the right. If the expression is
[tex](x+2)^2[/tex] for example, it can be rewritten to be understood as
[tex](x-(-2))^2[/tex] where negative is indicative of movement to the right. The location of the center of a circle will help you graph it.
In our circle, we have a -1 in with the x and a +3 in with the y. The -1 indicates movement to the right 1 unit (positive 1), while the +3 in with the y indicates movement to the left 3 units (-3). Therefore, the movement of the circle also indicates the coordinates of the center: (1, -3).
The radius is found in the square root of the number to the right of the equals sign. Ours is a 4; therefore, the radius is 2.
To draw this circle, locate the point (1, -3) on your graph paper and put a dot. Then count directly to the right 2 units and make a dot, directly to the left 2 units and make a dot, directly up 2 units and make a dot, and directly down 2 units and make a dot. Connect the outer 4 dots in as smoothly as possible to get a circle. And there you go!

Answer:
3x^4-24x^3+72x^2-96x+48
Step-by-step explanation:
1. (x-2)^4
=(x-2)(x-2)(x-2)(x-2)
=x^4-8x^3+24x^2-32x+16
2. 3(x^4-8x^3+24x^2-32x+16)
=3x^4-24x^3+72x^2-96x+48
Identify any outliers of the data set. Then determine the effect that the outlier has on the mean.
375, 350, 400, 375, 375, 425, 350, 125, 400
I swear I get so confused with these-
Answer:
125 is an outlier
125 changes the mean by 23 points (from 375 to 352)
Step-by-step explanation:
an outlier is 1.5 times the IQR
the InterQuartile Range of this set of data is 400-350 or 50
50 x 1.5 = 75
the only data value that is 75 points from the IQR is 125

Ethan has packed 6 shirts, 4 pairs of pants and 2 pairs of shoes for vacation. How many possible outfit combinations does Ethan have for his trip?
4
48
12
6
Answer:
Ethan can make 48 possible combinations.
Step-by-step explanation:
Given that Ethan has packed 6 shirts, 4 pairs of pants and 2 pairs of shoes for vacation, to determine how many possible outfit combinations does Ethan have for his trip the following calculation must be performed:
Shirts x pants x shoes = Number of combinations
6 x 4 x 2 = X
24 x 2 = X
48 = X
Therefore, Ethan can make 48 possible combinations.
Answer:
48

A circle with the diameter of 20 mm is showing what is the exact Sir conference obvious and then question to what is the approximate sir conference
Answer:
The approximate circumference is 62.8 mm
Step-by-step explanation:
Circumference is basically the perimeter of the circle
Circumference is given by
[tex]2 *\pi *r[/tex]
Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm
Substituting the given values, in above equation, we get -
Circumference =
[tex]2 *3.14 * 10 \\62.8[/tex]mm
The approximate circumference is 62.8 mm
Un camion transporta aceite de oliva en un deposito con forma de cilindro de 1m de radio y 5m de altura . Si en cada viaje que realiza lleva el deposito lleno . ¿ Cunatos metros cubicos de aceite transportara ?
Answer:
15.71 metros cúbicos de aceite transportará el depósito del camión.
Step-by-step explanation:
Un camión transporta aceite de oliva en un deposito con forma de cilindro de 1 m de radio y 5 m de altura.
Para calcular la cantidad de aceite que transportará se debe calcular el volumen del depósito, siendo con forma de cilindro. El volumen de dicha figura es calculada como V=π*r²*h, donde r es el radio y h es la altura.
En este caso, el volumen del depósito cilíndrico es:
V=π*( 1 m)²*5 m
Resolviendo:
V=15,71 m³
15.71 metros cúbicos de aceite transportará el depósito del camión.

You have a picture that is 4 inches wide by 6 inches long. You want to reduce it in size to fit a frame that is 1.5 inches wide. How long will the reduced photo be?
Answer:
2.25
Step-by-step explanation:
A picture is 4 inches 6 inches long
The length at which it would be reduced to can be calculated as follows
6/x= 4/1.5
Cross multiply
4x= 9
x= 9/4
= 2.25
Hence the length would be reduced by 2.25

Christy rented a banquet hall for her company party. There was a non-refundable deposit of $300 to reserve the space and an $85 fee for decorations. The banquet hall charged $27 per person for food. Their total bill was $2,653 for b employees.
Choose an equation that represents the total cost of the company party. Then, choose the number of employees that attended the party.
412b = 2,653
112 employees
7 employees
27b - 385 = 2,653
27b + 385 = 2,653
84 employees

Find the value of X. show your work (geometry)
Answer:
x = -6
Step-by-step explanation:
x + 121 = 115
subtract
x = -6
Answer:
x=-6
Step-by-step explanation:
the 115° angle and (x+121)° angle are alternate exterior angles, meaning that since lines are parallel, these angles are congruent
to find x:
x+121=115
x=-6

Use the Zero Product Property to solve the equation (x – 5)(x + 4) = –14.
Answer:
x = 3 or x = -2
Step-by-step explanation:
(x - 5)(x + 4) = [tex]x^{2} - x - 20[/tex] = -14
[tex]x^{2} - x -6 = 0[/tex]
(x - 3)(x + 2) = 0
x = 3 or x = -2

What is the end behavior? (select 2)
Ignore: need to be 20 characters or more
Answer:
The correct end behavior are;
As x approaches positive infinity, y approaches positive infinity (D)
As x approaches negative infinity, y approaches positive infinity (B)
Step-by-step explanation:
Here, we want to get the end behavior of the graph
Kindly note that the upward arrow represents a movement toward infinity
Thus, we have it as follows;
As the value of x increases (towards the right); the value of y tends toward positive infinity
secondly: as the value of x decreases, tends toward the left, the value of y also tends toward positive infinity
You Have Tiangle XYZ with X(-7,-9), Y(-10,-3), and Z(-1,-9) After a 90 Degree Counterclockwise rotation, what is the new coordinate of Z'?
Answer:
Z'(9, - 1)
Step-by-step explanation:
For a 90 degree counterclockwise rotation about the origin,
The original coordinates of point P (x,y) will now be positioned as P' (-y,x).
Hence, given :
Triangle XYZ with X(-7,-9), Y(-10,-3), and Z(-1,-9)
The new position of Z denoted as Z' will be :
Z(-1, - 9) ; X = - 1 ; y = - 9
-y = - - 9 = 9
x = - 1 will remain as - 1
Z(-1, - 9) - - - > Z'(9, - 1)
