Find an equation of the circle that satisfies the given conditions. (Use the variables x and y.)
Center (−3, 4),
radius 3
Answer:
(x +3)² +(y -4)² = 9
Step-by-step explanation:
You want the equation of a circle with center (-3, 4) and radius 3.
Circle equationThe equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
ApplicationYou have a circle with center (h, k) = (-3, 4) and radius r = 3. Using these values in the above equation, we find the circle equation to be ...

How do you model a situation in which a function behaves differently over different parts of its domain?
Enter your answer.
The situation in which a function behaves differently over different parts of its domain is modeled by considering it to be a piecewise function.
What is Mathematical function ?
Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable
Such a situation can be explained through an example:
f(x) = { x, for x > 0
{ 1, for x = 0
{ -x, for x < 0
now, when we take x value less than 0, say x= -1
thus, f(x)= f(-1)= -(-1) = 1 , here we used f(x) given x<0
now, when we take x value more than 0, say x= 1
thus, f(x)= f(1)= (1) = 1, here we used f(x) given x>0
now, when we take x = 0,
thus, f(x)= f(0)= 1, here we used f(x) given x=0
this is how we model piecewise function, we use f(x) as per the value of x. Following image shows plotted answer for this example.
Since inequalities given are exclusive of 0, we leave the dot at the origin unfilled. Now, for x = 0. Since the value is constant at f(x) =1, we pointed a point at (0,1)

A health food company packs almond butter in jars. some jars hold 250 kg. other jars hold 500g. on tuesday, the company packed 186.5 kg of almond butter in 511 jards. how many jars of each size did they pack
In linear equation, there was 235 jars with 0.5 kg almond and 276 jars with 0.25 kg almonds.
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Let the number of 250g=0.25 kg jars be x and that of 500g=0.5 kg jams be y;
therefore:
total number of jars was
x+y=511
x=511-y..........i
total amount kg was:
0.25x+0.5y=186.5....ii
substituting i in ii
0.25(511-y)+0.5y=186.5
127.75-0.25y+0.5y=186.5
solving for y we get:
0.25y=186.5-127.75
0.25y=58.75
y=58.75/0.25
y=235 jars
and
x=511-x
=511-235
=276
hence , there was 235 jars with 0.5 kg almond and 276 jars with 0.25 kg almonds.

Given the product (x+8) (x+3) do the following.
(a) Show that this product is equivalent to x² +11x + 24 by using any acceptable method.
(b) Test the equivalency by using x= 1. Show the intermediate calculations.
The product or multiplication of the polynomials is given as
x² +11x + 24.
A result or product is produced by multiplication or a statement that lists the factors to be multiplied.
The commutative law of multiplication states that the product is independent of the sequence in which real or complex numbers are multiplied.The order of the factors often determines the outcome of multiplying matrices or the constituents of other associative algebras.For instance, multiplication in general and in matrices are non-commutative operations in other algebras.Additionally, two complex numbers can be multiplied to get a complex number. When we multiply two integers, we always get back an integer.Given (x+8) (x+3)
let us find the product :
= x² + 8x + 3x + 24
= x² +11x + 24
Let us now test the equivalency .
(x+8) (x+3) = (1+8)(1+3) = (9)(4) = 36
x² +11x + 24 = (1)² + 11(1) + 24 = 36
Hence we can see that the product is same in both the cases.

Let f(x)=(x+1)²-2 . Find the x -and y -intercepts of f(x) and the inverse of f(x) . Is the inverse a function?
The x-intercept of the function are (√2-1,0) and(-√2-1,0). and the y-intercept of the function is (0,-1) and the inverse of the function is f⁻¹(x)=±√(x+2)-1.
The x and y intercepts of a function is defined as the points on the cartesian plane where the graph of the function intersects the co-ordinate axes.
The intercepts are calculated by substituting the value of x and y to zero to calculate the corresponding variable.
The inverse of a function y=g(x) is calculated by finding the value of x from the equation.
At x=0 , we get the y intercept.
f(0)=(0+1)²-2
or, f(0)=-1
So the y-intercept is at (0,-1) .
At y=0 we get the x-intercept.
f(x)=0
or,(x+1)²-2=0
or,(x+1)²=2
or, x+1= ±√2
or, x=±√2-1
Therefore the x-intercepts are (√2-1,0) and(-√2-1,0).
Now let us calculate the inverse of the function.
y=(x+1)²-2
or,y+2=(x+1)²
or, x+1=±√(y+2)
or, x=±√(y+2)-1
Hence the inverse of the function is written as
